One thing I know for sure, when you are a 'beginner' at any hobby or sport, it's obvious. There is no shame to being new, but I think a lot of people have hesitated to try something new, just because they do not want to be the 'new guy'. I say, 'get over it'. Everybody was new once.
Let's look at the radio controlled boats hobby. I can vividly recall my husband's first year of running rc boats. I witnessed his progress from the sidelines, but made some observations that may help you.
The important thing is to realize that you are 'new', and to pick one of the radio controlled boats that suits your ability and skill level. Trying to start at the top will only lead to frustration, embarrassment, and perplex failure. My husband did a little research, and decided to start with an electric radio controlled boat. Wise choice! He read that these radio controlled boats were easier to handle, and require a lot less maintenance.
The next thing he did, and probably the hardest thing, was introduce himself to a group of guys at the lake that appeared to know what they were doing. Breaking that 'ice', and letting them know that he was a new rc boat guy, really was a good move. The group immediately took him under their wing, and were generous with their time and advice.
In no time at all, my husband had the confidence to run his boat side by side with his new found friends. So, my advice is two-fold. First, if you are going to give your hand a try running radio controlled boats, choose the right equipment … do a little research and start small.
Second, do not be shy. Hobbyists are generally happy to welcome someone new to their world. You can learn so much more from their experience than you can reading through literature. Not only that, but you will earn their respect by being humble, and seeking out their help. What a great way to build new friendships.
As I mentioned earlier, everyone has to start somewhere … we are all the 'new guy' once!
If you are in need of a group project for a kids club and would like to teach basic wood crafting skills, consider a simple birdhouse or shelf. For projects this size, the wood craft supplies can be fairly cost effective, especially if you are willing to use scrap lumber and borrowed power tools. Many people are more than willing to donate or offer use of tools and supplies, you may even get volunteers to help with teaching. Even so, you will still need to buy a few essential wood craft supplies. Check funds from your clubs treasury and make a list.
Purchased Wood Craft Supplies
Sandpaper-No matter what project you are underaking, you will need sandpaper to eliminate cut and splintered ends and to smooth surfaces. Sand paper comes in many grits, you will need an assortment of all kinds.
Wood screws and nails-It just would not be wood working without drilling or hammering. Purchase wood screws and nails that are long enough to attach your wood together.
Wood glue-Applying wood glue to joints before attaching with wood screws and nails will insure a long lasting bond. Once the glue has been applied and the joints put together, wipe off any excess glue that has squeezed out. Wood glue does not dry clear.
Paint and stain-Small bottles of paint can be purchased at craft stores or hardware stores. Clear spray sealer is a wonderful finish to apply to a birdhouse, after it has been completed, to seal the paint from the weather.
Borrowed Wood Craft Supplies
Jig saw-This saw is a versatile tool for woodworking. It can cut dowels to size or cut simple shapes that have been drawn out on wood.
Power drill and bits-Drilling a pilot hole before adding a wood screw will eliminate splitting. Use a drill bit to drill the hole, change to a screwdriver bit and attach the screws.
Miter saw-A chop saw is perfect for cutting straight cuts on narrow boards and, as the name implies, mitering angles.
Sander-An electric sander will give faster results than sanding by hand, which can overwhelm some wood crafters. Some electric sanders are even small enough to reach tight corners.
Clamps-A third hand is always nice when woodworking. Clamp wood to aid while cutting, drilling or to hold glued pieces together while glue is drying.
Measuring tape-There is an old saying, "Measure twice-cut once". Enough said.
Goggles-Eye protection is a necessity for all aspects of woodworking. If you can not see your project when you are finished with it, it was not worth doing.
Note: Never allow children to handle power tools of any kind without constant, hands on, adult supervision.
The Internet is full of simple wood craft patterns that are free to download and copy. Consider designing your own if you can not find what you need or want. Visit your local library for an abundance of books on the subject or scan the magazines at your local supermarket for wood craft topics.
Wood crafting can instill a life long skill and interest in a child and years of accumulating his or her own wood craft supplies.
Most people have hobbies because they have been interested in them for a very long time. However a hobby like stamp collecting, will entice you even if you have never thought of it before. You will be surprised at how nice it is to look at the stamps in an album. The bright colors and fine print are often too hard to resist appreciating.
Taking up new hobby however, takes some guts. As beginners, you may not know anything about stamp collecting. You need a guide to tell you how to start, how to proceed. Read this article and you will find out more.
Stamp collecting is very simple but it requires some patience. You need patience because it is not every day that unique stamps are produced and it is also not every day that you can find unique stamps. To begin collecting, read on more:
1) Purchase a large amount or packet of stamps to begin with. Alternately, you can remove stamps from packages. This will give you a head start to your collection.
2) In order to store the stamps, you need to purchase an album in which you can store your stamps in. Purchase a good quality album and do make sure that the album is large enough to store all your stamps in future.
3) Buy hinges. Hinges will help you to fix the stamp to the album. It is not advisable for you to paste the stamps with glue as it make a permanent arrangement and you would not be able to classify your stamps later.
4) Keep the album in a safe place. You can also keep your album in a polythene packet so that they are not wetted by water.
If you want to take a closer look at the stamps you may need the tools to look at it. They are:
1) An album or an archive stock book. Since you would already have one then this would not be a problem.
2) Magnifying glass. This is important as your may not be able to see the fine details of the stamp with your naked eye. You need a magnifying glass to take a closer look at the stamps.
3) Stamp tongs. Stamp tongs are small tongs with rounded tips. This is to prevent damage from skin oils and rough handling.
Stamp collecting is very simple and it does not require you to spend much money on it. Now, your stamp collection is only one step away.
Dog grooming can be very expensive if you visit a pet grooming salon. However, you must not compromise your pet's hygiene and overall physiological and psychological health by ignoring its need to be well-groomed. Just like people, they also need some pampering and grooming now and then so that they look and feel better.
Fortunately, you do not need to spend a lot of money on dog grooming. There are various ways in which you can take care of your pet by yourself in your own home. All you have to do is purchase some grooming tools and supplies and follow these tips on how to properly groom your pet.
The first thing you have to consider is your dog's coat. You do not want your pet to develop problems with fleas and other pests so you must always clean and maintain your pet's hair. One very essential pet supply is the soft-bristled brush. You have to make sure that you brush your dog's coat every day to prevent it from becoming tangled. Regular brushing will also make the coat shiny because it stimulates and spreads the natural oils found in the coat. It prevails shedding because it removes dead and dying hair.
As well, you need to have your dog's coat trimmed every month or two, depending on the breed. If you want to do this on your own, you need to have clippers or trimmers, scissors, a brush or a comb, a blow dryer, and towels.
Next, when it comes to bathing your dog, you need to get a good dog shampoo and soap, towels, comb, and brush. Before the bath, brush your dog's coat so that it does not become tangled when it gets wet. You have to bathe the dog every month (for dogs with long hair) or every two months (for short-haired dogs) or whenever the dog needs it (eg when it has rolled over in the mud or something smelly). Regular bathing will prevent your dog from getting fleas and other skin diseases. It also keeps the dog smelling nice and feeling clean.
Dog grooming also involves nail clipping. Your dog's nails grow just like yours and longer nails can do a lot of damage to your home. They may also break off, which would be painful for your pet. Therefore, you must cut your dog's nails about once a month. This is not like clipping your own nails because a dog's nails are shaped differently and are much thicker. You'll need to use a dog nail trimmer. You should also have some blood-clotting powder handy if the need arises.
Twice a month, check your dog's ears for fleas and infections. Then clean them using cotton balls, warm water, and mineral oil.
Finally, not only people have to brush their teeth. Your dog can also develop cavities and other diseases of the mouth, teeth, and gums. You need pet toothpaste and a toothbrush to clean the mouth twice a week.
Model trains are a hobby that fascinates enthusiasts and attracts admirers from all over the world. When taking up this exciting hobby, some thought should go into what type of model railway you wish to build as model trains for beginners can be overwhelming if you just dive in. This creative past time is the perfect way to display skill, imagination, and capture the wonderful essence of historical railways and trains with nostalgic memories of the past.
Whatever your vision is, spend some time planning your model railway and join a local enthusiasts club where you will find plenty of helpful tips and hints to get you started. Many small model railway projects start small and expand into complex systems capable of operating several trains at once in all kinds of different terrain. The tips in this article will help you plan and think about how to commence your own model railway.
Theme and Era
Are you looking for the days of luxury trains like The Flying Scotsman or Orient Express, or looking to the great Trans continental railways like the Trans Siberian Express or the Indian Pacific, which ran on the world’s longest straight stretch of track across Australia? You need to decide on the year, the country and the rolling stock and trains you require. This is a very exciting task, and your project will evolve from these ideas.
Model trains for beginners should not be over ambitious and should allow enough space to show off the layout without overwhelming the room for a first time model. You can always expand or start a new project that is wall to wall. All model railways are a labour of love, and it is best to start small because of all the detail involved.
If you have a small display space, then a smaller scale model railway will work better although more impact is needed from the scenery and setting. Larger scale models are easier to work with, but are more expensive.
Plan of the Track
Your track design has several options, and it is best to draw some different configurations on graph paper. Once you are satisfied with the layout of your track, you can use your sketch to build it into your setting.
Which Track Type to Use
There are many different brands of track on the market with varying rail sizes, roadbed attached track pieces and track only. Custom curves can be made from a flex track product. Review and try different types to see what suits you.
Display Table or Bench
Before deciding on the size of display area for your model railway, you can do a dummy run with your track on the floor. This will give you an idea of overall size required. Estimate how much extra will be needed for scenery and extras. This will give you the size of board, bench, or table for your display.
Electronics and Wiring
The operation of your model railway can be very sophisticated with digital command control (DCC) that enables you to operate two or three trains at once. Locomotives are electronic, but many other components and accessories are also electronic which will give you an authentic replica of a real railway with lights, switching of tracks, steam and smoke, whistles and other sounds. You can even buy tiny video cameras to record your train’s journey around your personal layout, which is great fun to watch.
Starting a model railroad can turn into a life long experience with something new and different to be added every day as your imagination updates your vision. Model trains for beginners are a rewarding and interesting hobby that not only gives satisfaction to the modeller, but also to people who see it. Just remember to plan carefully for a layout you will have for life.
Citizens band radio or more commonly called "cb radio" offers many type of radio experiences for such as small number of legal to use channelized radio frequencies. As an example you man want a cb in your car or in your home. Perhaps you might have a business reason, you may be interested in starting a new hobby, whatever it may be.
This article is written for beginners in cb radio or people who may be thinking of getting a radio. I will cover what kind of radios are best to get when starting out and why and if you decide to try out the hobby what happens to most new comers. Do not worry it only hurts your pocketbook.
Almost all CB radios have a channel selector on its face and some kind of lighted indicator showing a number, generally 1-40 or 1 -23. The radios with 23 channels are older and unless you get one for really cheap or free, I would not purchase one of these units. There are alot of fine older units out there but for reasons Ill explain later, you should get a newer setup. If it does not make sense just read on it will all become very clear to you.
Mobile Vs.Base Type Units
CB's, for the most part, come in two flavors, base or mobile types. The mobile units are smaller but can have all the features of a base radio, equal power output, however, there is one draw back to the reduced size and that is the size of the control knobs on the front. Generally speaking, base radios have larger knobs and in most cases more of them when compared to the mobile unit. What does this all mean? If you have fat pudgy beer drinking fingers, fiddling with small knobs in heavy traffic may prove to be a complete pain in the butt. That choice will be up to you.
Almost every mobile CB radio has an internal speaker, generally on the bottom of the radio. These speakers are garbage. They are overrated, cheap and sound bad. Consider an external speaker when space is available.
Some base cb radios will have a speaker built in, they sound better than the mobile but again a quality external speaker should be considered as well.
Most base station radios also have an internal power supply. It is something to consider when purchasing a setup. Mobiles are designed to run from a car battery so generally have no 110 volt plug. Base units, on the other hand, have built-in power supplies and it's easy to just plug them in. If you decide to use a mobile as a base station just remember that you will have to get a 12 volt power supply or have a spare car battery handy.
Range distances on mobiles are also much less compared to base station due to the size of the antenna.There are glass mount cellular look- like antennas to 8 foot w wave antennas. The minimum length for a mobile setup to begin to perform decently is 40 inches. Anything less is a waste so that cellular look-alike might look cool, but it will not have a very good range, maybe a mile or so.
Basically what it boils down to is the larger and higher up your antenna is physically, the further the range of your radio will be assuming everything is working properly.
CB Radios as a Road Trip Companion
A cb radio in your car can be a very valuable tool. You can get tons of real time road information from trucks, you do not really even have to talk. Just listening will yield a lot of stuff about road conditions ahead, you will hear about accidents or traffic jams way before any broadcast band gets the info. The best part is almost all the time you can hear where any speed traps may be. The draw back to all this wonderful information is what you have to hear in between the reports. It's not something you want to you kids to hear generally. If you do not care and its just you and you wife or girlfriend then turn it up and join in. It can make a long drive seem short when your yacking the whole time. You may even be able to make a report if you see something first. The one question I hear the most from trucks is about the status of the roadside scales. You can talk all the mess you want on the radio but do take notice as you pass scales on the other side of the road you are driving on. For example, if you are traveling north on a freeway, look for scales on the southbound side. Check to see if they are open or closed and pass that information on as you drive up the road to the trucks and continue your fleeting.
CB Radios as a Base Station
And still another side to CB radio is the base station. You will find that there is generally a "local channel" in almost any city. There you will find normal people to tweakers and anything in between and like the truckers you most likely do not want you kids to hear what comes peoples mouths.
Having a base station usually means a larger antenna, which equates to consider longer communications in terms of distance. Even with a 4 watt radio (the FCC Legal limit) it's not uncommon to 10 or 20 miles. If you live in or close to a larger city, there will be lots of people at what would seem to be all hours. The CB never closes.
CB Begins to Overtake your Life
So you get your base running and get out there. It becomes instantly addicting. Friday nights will be spend more in the garage drinking beer and talking on the radio. You will hear lots of things about radio and receive advice from many people. One of the first things almost every CB'er wants are modifications to the radio. Usually to be louder and have big signals at the receiving stations are the 2 most common configurations with being louder quite possibly being number one.
Being Louder?What Does that Mean?
Here is where the line is drawn between what is technically correct and what people want. It is true that a "stock" radio will be able to be heard at a receiving end, but the real question with regards to the human psyche is how it is heard.
You can equate configurations on a CB radio to having a car and by changing certain parts or modifying the engine, wheels, tires and so on, will enhance it's performance and make your experience driving the car more pleasurable. It becomes validated even further when a friendly street race is won. This is absolutely no different than the modifications to a CB radio where fellow CB'ers take notice that your voice in their speaker is louder than others. Often referred to as "Tree Top Tall or Walkin the Dog and Kickin 'the Cat." You get the idea.
It is here where your first questions will need to be answered. I am of the opinion that having a great microphone is important first. It will not take long for you to hear of the infamous Astatic D104 base microphone. (Be aware that there is a mobile version which is loud but it's tonality sucks) The base version is an impressive looking piece and has a reputation of being a "loud" microphone meaning that all you have to do it plug it in and instantly your Loudness will change, and it will from the stock microphone for sure.
I think that the D104 is a good microphone and it is loud, however, it's tonality is not acceptable due to its pre-amp (the electronics contained in the base of the unit). When I use the word tonality I'm referring to how well it's amplifying in terms of sound quality not unnecessarily loudness. Of course there are many more variables than just the microphone's pre-amp but if the microphone does not have the capability to capture and reproduce a natural, tonally pleasing sound or your shot at better than average audio is gone right there. At this point you may as well hammer a screw into a wall with a wrench. It will not make much difference what mods you make to the radio if the microphone can not keep up.
Radios that I Think are Great Starter Units
I have to say that there are many great radios out there. I have created this list based on
Cost vs. Performance
Availability of parts
Ease of finding shops that work on the models
Abundant information available and easily accessible
Good resale value
Cobra 25/29 Classic, LTD 148 GTL Cobra 2000 GTL – Base Unit Cobra 142 GTL – Base Unit
Uniden PC 66/76 Uniden XL
President Washington – Base Unit (There are two versions) one with one meter or dual meters. The unit with one meter is almost a cobra 148/2000 – There are some slight differences technically but the version with dual meters is nothing like any of the radios listed here despite it's same name. If you end up with an obscure radio, the time a tech will need to review the schematic and come with some mods either may or may not be possible or just too costly to justify.
Example One: You buy an obscure radio for 40 dollars in a working, stock condition. Next you get a D104 and I ll just say it's 60 dollars. You take the radio to the techs place, he / she has little experience with this model. If the tech does not have the schematic, you will have to provide one or wait and it will cost more money, say 15 dollars. Now wait more till the tech figures out a modification. Or maybe he / she just gives it a "tune up" (that is left to be interpreted by anyone as to what it really is) and charges you 40. So after 155 dollars you have a D104 and a radio that really has nothing done To it. When people ask you about your radio setup (and they will) you will find yourself making excuses why you have that radio as in "I got it cheap".
Example Two: You buy a Cobra 25 or 29 for 40 dollars + D104 for 60. The tech has done many of these radios, probably has all parts on hand and can do some good mods in just a few hours. It may cost 75 dollars but look at the math. It adds up to 175 total but you have your radio back in a very short time, the configurations will have made a tremendous difference and your loving life. When people ask you about your setup, your proud of it and instead of making excuses you talking about taking it to the next level, moving up in the CB world. It can make or break your CB radio experience. Trust me on that one.
This pattern teaches you how to crochet a simple single crochet dishcloth that is ideal for beginners to learn on. The dishcloth pattern is easy to crochet to any size you want, making the pattern great for blankets, scarves or anything else you like.
To get started, you will need a worsted weight #4 yarn. The yarn labels will provide you with the information. As for your crochet hook, I used an H/8-5.00mm hook, but an I/9-5.50mm will work just as well for this yarn and pattern. It’ll just come out a bit bigger.
To crochet the dishcloth, make 21 chains.
Row 1: Single crochet in second chain from your hook. The skipped chain does not count as a stitch. Then single crochet in each chain across. Turn your work. (You will have 20 stitches made.)
Rows 2-24: Chain 1. Then work 1 single crochet in each stitch across. Turn after each row. (20 stitches in each row)
If you don’t mind the jagged edges, you can leave the dishcloth as is and fasten off your yarn. However, for a nice smooth edge, you can work a round of single crochet stitches around the dishcloth. To do that, make your chain 1. Then work 1 single crochet evenly around, with 3 single crochet stitches in each corner. Once you get all the way around, you will join the round with a slip stitch. Now you can fasten it off and weave in your ends to secure it.
You can also use the above pattern to make a scarf or a blanket. The only thing you would change is the number of chains that you start off with.
If making a scarf you might want to start off with fewer chains; about 15 would give you a nice width. Then simply repeat the 2nd row until you have reached a length that you like.
As for a blanket, you could start off with a 100 or 200 or more, depending on what size you want. A baby blanket would only need about a hundred or so, whereas a full-sized blanket would need a greater width.
Another option you have is to change up your yarn and hook sizes. You can basically use any yarn and hook size, just make sure to measure your chains in order to get the width you need. You could also add pretty stripes by changing your colors after every row or every few rows.
When I first started racing Gas Powered RC cars, I used to struggle to get the engine into tune, while I was able to get the engine to start on a dime and it used to run fine for almost an entire fuel tank, it always seemed to over-heat near the end of the run. After many hours out on the track I can now finally say that I’ve got it down, tuning for me is now a 5 minute operation before I take my RC car out, and once it’s dialed in I only need to adjust one needle a fraction of a turn to get it back to it’s optimal settings.
I assume that your understand the basics of a RC Nitro Engine and how it works, if not please see my other articles which you can find on my website, see the resource box for details.
The Idle Screw
I always start with the idle screw, I adjust it so that the car will idle high when I’m first dialing in the engine. Once I get the engine up to temperature and with a tube that can keep it running without stalling I slowly adjust the idle down to the point where it’s about to stall, then I turn it back about 1/4 to 1/2 turn depending on the temperature. If your car stalls often it can be worth while increasing the idle to prevent this, it’s only a temporary fix while you sort out the other tuning issue, but it helps keep frustration levels down.
Low Speed Needle.
One of the great debates is which needle to adjust first, if your carburetor only has one needle adjustment screw then it’s not a problem, but if like most glow engines you have two you need to decide which to tune first. I always start with the low speed needle, this is because when you adjust the low speed needle you change the high speed needle. Once the low speed needle is dialed in you shouldn’t have to adjust it again. Make sure you keep it slightly on the rich side, when you RC Car idles the combustion chamber should start to fill up with fuel, this helps keep it cool. After a while the engine will stall, by measuring this you can tell if it should be richer or leaner. A good time is about 30 – 60 seconds before it stalls. The RC Car should pull off quickly from a standing start and should not bog down or flame out when you apply full throttle.
High Speed Needle.
Once you have your low speed adjustment needle dialed in it’s time to start getting the power out of the RC engine. This is done with the high speed needle, which adjusts the air to fuel mixture of the engine while it as high RPM (about 40% and up). Keep an eye on the trail of smoke as this is your first clue about the tune. You want to have a lot of smoke coming out of the engine at all RPM, if at some point there is little or no smoke then you are running too lean.
Hints, Tips and Tricks
Turn the needle clockwise to lean out and counter-clockwise to richen the mixture.
A lot of smoke means you tune is rich.
The sound can tell you about your tune.
Reading your glow plug after a run will tell you a lot about your tune.
Make sure to run your engine on the rich side, this will extend it’s life.
A lean engine will always put out more power, but it will shorten the life of your engine.
Temperature, air pressure and humidity play if big part in the tune, different days will need different settings.
Flying an electric RC airplane is like having beginners luck every time you fly. The first remote control airplane I ever got was electrically powered, I had no flying skills whatsoever, and I still managed to fly it perfectly without even crashing. Why you ask? Because electric RC planes like the one I had are so simple, they only have two control options, power and steering. You go as fast, or slow as you want and just choose your direction.
Now yes, there are electric RC planes that you can buy or build, that have many control channels and all the works, like flaps, ailerons, etc. Those types of electric airplanes are basically made for advanced flyers who don’t like the mess that comes with the use of fuel. Most hobbyist start with an electrically powered plane, then move onto fuel powered ones once they have mastered it. But like I said, some people just don’t like the mess and added expense that comes with a fuel powered engine, so they stick with electric motors. Fine, do whatever makes you happy, but I am just going to talk about getting a good electric RC plane for a beginner pilot.
Now first off you should note that electric airplanes can come in a few different types. Basically there are only park flyers, slow flyers, regular electric planes and advanced electrically powered RC airplanes.
Park flyers are mainly for parks and small areas similar to that outdoors. Slow flyers are just the opposite, since they move slower they are for indoors. These can be great for the winter or when it is just plain to windy outside to fly.
A regular electric RC airplane is the best for beginners and is exactly what I flew as my first RC airplane. Usually these planes are priced around $50 and they have just two controls, so it is ideal for beginners. This type of airplane is usually made of Styrofoam, and very little metal, so you need to be careful when flying it. Even if you do crash and damage something, usually a little duct tape will fix anything on it. I kid you not, I still have my first electric RC plane, which I broke the wing twice on, and it still fly’s!
An advanced electric RC airplane is ideal for advanced pilots who don’t like the mess of fuel, like I said before, but it is also great for areas where noise is a concern and you still want the full experience. Advanced electric R/C airplanes are more full bodied then regular ones, usually made of all plastic and balsa wood, plus they also have around 5 or 6 channels of control.
All in all, buy a park flyer if you just want a quick little flight every once in awhile, get a slow flyer if you want to fly indoors, purchase a regular electric RC plane if you want to get into the RC airplane hobby seriously, but are just a beginner. Last but not least, once you master an electric RC plane, move onto a more advanced nitro methane fuel powered one, or an advanced electrically powered plane.
Labrador Puppy Training For Beginners Labrador puppy training needs to begin as soon as possible. This breed of dogs have a huge amount of potential in their blood. Besides being one of the most famous breeds around the world, it is also known as the official assistance dog for people with disabilities. Training Labrador puppies shouldn’t be a hard task, but it will require some patience on your part. These are Labrador puppy training tips that your dog must know and obey if you ever planning on taking your dog out in the public.
First your Lab needs to know his/her name, and come to you as soon as you call. You can start by waiting for your puppy to get distracted, than call out his name and the moment he pays attention reward him with a tasty treat. Do that over and over until he gets the point.
A Labrador will grow up to be a pretty large dog, so you have to teach him how to walk on the lead without pulling or jumping whenever he sees a stranger. Whenever the puppy starts pulling administer a sharp tug and say heel. After a while he will translate heel as walking calmly by your side. And when he does, start concentrating on getting him of the lead and walking next to you without it.
Keep in mind that rewards (treat) will get far better results than fear when training Labrador puppies. Basics such as knowing his name, or when to sit are the best to start with for Labrador puppy training.
