Holly crap, this is one of the coolest things I have ever seen! It was love at first sight, I have got to make one of these. The great thing is that it is all open source, so that you can build one and help to make it better. I can think of about a billion things that I could make with it. I am not one who has a lot of experience with electronics but I think that I could have a friend help me with that, I know that I could put it together fairly easy it looks manageable, and it might take awhile but I could figure out the software. So tell me what you think, I would like to here your thoughts on this one. I have provided some links below to help you get started.

How to Make a simple Smoke Bomb
This is one of the best smoke bomb recipes that I have come across, mostly because of cost. It costs about 3-5 dollars depending on the cold pack that you buy and if you waste your money on a subscription to the newspaper. Any way you soak the newspaper in ammonium nitrate and water mixture, then you sun dry your newspaper, once dry you roll it up and light it, it is that easy. Note: I wouldn’t breath the smoke. Also you will need to make sure that the cold pack that you buy contains ammonium nitrate.
The King of Slingshots
I have been watching this guys inventive ways of making slingshots. Although he does not teach you how to make them, he does give you some cool ideas for a slingshot. Take a look at his videos I bet you will enjoy them as much as I have. I may even do a how-to video based on some of his ideas.
Also here is a cool Forum about slingshots: http://slingshotforum.com/
Woody Norris inventions are awesome
I am starting a new thing here at the Mans Cave. What I will be doing is blogging about cool videos that I come across, videos that I feel deserve some attention. I will add a new page to the blog that is just my videos so you can find my personal work at anytime.
I picked this video first because of the cool thing that Woody Norris has invented, that has made our lives easier and the cool inventions that he is working on. I also started with this video because I also hope and aspire to becoming an inventor.

How to Make a Mini Cannon that shoots bb’s
I saw a couple videos where these mini cannons were shooting at targets and just destroying them, and I was hooked. So, I decided to make a video showing how an individual could make one of their own. I also sell these cannons in my Products section of the website, if anyone is interested. We are extremely excited to announce that we will be giving this 
mini cannon away!!! The day will be May 15th @ 8:00 P.M. mountain standard time, all you have to do to qualify is to subscribe to my youtube channel CLICK HERE. I will be using a random generator to pick the winner.
I have always enjoyed making things and these cannons are not all that hard make and are inexpensive, making it one of the best projects you can make.

- Brass rod (found @ metal supply).
- 1 inch Square brass tube.
- 6-32 knurled nuts (hardware store).

How To Make a Globe Torpedo / Fireworks from Matches
I finally got another video up. This video of how to make globe torpedoes was really fun, it is something I have made for years. Globe torpedoes, well the real ones were actually banned in the 1950′s due to injuries caused by them. They were made of a shock sensitive explosive, surrounded by a clay ball, similar to the air fire clay you can buy from hobby stores. Anyway, mine are a little bit safer but still have some apparent risks. If you choose to make them, I would suggest that you wear safety glasses during production as well as when you are setting them off. Be careful where you set them off, they could start a fire.
I found, that the balls out of the toy shooters work really well. I also saw some plastic golf balls in wally-world that might work, but I have never tried them.
Parts list: Plastic Balls, Strike anywhere matches, tape of almost any kind, and very small rocks.
Homemade Tannerite From Instant Cold Packs
I made this video because I noticed one day that instant cold packs or at least the one I was looking at, contained ammonium nitrate. The main ingredient in Tannerite. And I thought it would be cool to make Tannerite out of something found at a drug store. It may just be me? I think that is very cool. You can also make NegativeX with it, how cool is that?
Aluminum powder is the other ingredient in Tannerite. I used German Dark, Indian Blackhead would also work, and Magnesium powder or Magnalium powder might work.

How to save $$$ using a homade Peanut foam maker
I made this item about 8 years ago. We have used it to make over a hundred bags of peanuts or loose fill. Like I said in the video you get your Styrofoam from furniture stores. Now you can go dumpster diving for it, or you can ask for it. Either way tons of this stuff gets thrown away everyday, so its perfect for a low cost alternative to loose fill peanut foam. And if you are concerned about the environment than you can feel like you doing something to help…
I also had the thought that if somebody was looking for a small business idea you could contact all your local furniture stores, and contract to pick up there unwanted Styrofoam, it would save them loads of room in the dumpster, saving them money. Then you make your loose fill and sell it to anybody that ships.
NOTE / WARNING: Use in a well ventilated area. The p-foam maker putts off harmful CFC’s that can be very harmful to breath. Also it is not a bad idea to wear a respirator to protect your lungs.
Parts:
- Wood box
- Old heater
