This week I built a small air bazooka (vortex cannon) using just supplies I had laying around the house. This project didn’t cost me one cent to build since I already had all the materials laying around.
This week I’ve built a CO2 carbonator using parts mostly found from the hardware store. The CO2 tank is a 16oz paintball CO2 tank that I had laying around the house. The most difficult to find part was the paintball tank to CO2 regulator adapter. I had to purchase it online for around $7.00. I imagine you might be able to find it at home brewing store if you have one locally.
This carbonator can be used to add bubbles to pretty much anything with liquid and a thin skin. You can make soda water, carbonated fruit juice, or you can even carbonate fruit! I put orange slices and pineapple slices inside the carbonator and when they came out they were actually fizzy. It adds some extra fun on top of the already delicious fresh fruit.
I have found that you need to experiment with the pressure and the amount of time that your medium is pressurized. Different foods have different requirements and you can really only figure it out by experimentation. I can carbonate water in just a minute, but fruit slices might take an hour or so to get really fizzy.
Recently I’ve been fighting what seems like a list of never ending problems in order to get the Cisco Ironport WSA proxy to authenticate users properly in a Citrix environment. Every time I think I have it figured out something else breaks or, even worse, starts working intermittently. I finally figured out what it takes to make authentication work reliably in a Citrix environment, but it involves a compromise in security. Continue reading
Last weekend I decided to build a paper airplane crossbow for use at Eugene Mini Makerfaire. This project is fantastic because the only piece I had to purchase was the latex tubing. Everything else was scrap materials I found laying around the garage or shop. The whole project cost me less than $2.00 to build! Check out the video to get basic overview of the design, and to see it in action. This crossbow will launch a paper airplane clear across the room at high speed if the plane is designed properly. If you’d like to duplicate this build, I put together a very detailed set of build instructions.
I think it was somewhere around two years ago. I was kneeling on one of our wooden kitchen chairs. I had my knee right in the middle of the chair seat. Then CRACK. The seat snapped into two pieces. Cracked right in the center. Crap. Of course I said I would fix it since I had a whole shop at my disposal. Instead the chair ended up in the garage for two years. I finally decided to clean out my garage and of course I found that chair. Time to fix it. Once and for all. Continue reading
