Interesting water only cooler
This is an interesting build that basically uses water as a radiator like cooler (instead of the typical bucket cooler with ice). Nice build, curious how well it works thought. http://hackaday.com/2014/08/08/a-do-it-yourself-air-conditioner-with-evaporative-cooling-5-gallon-bucket/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+hackaday%2FLgoM+%28Hack+a+Day%29
Nice Write-up on building an Arduino Wireless Alarm System
Good write-up on how to build a simple, wireless (RF), alarm system with arduino and mini’s. I think it could be cheap’ed down more if so desired too. http://www.instructables.com/id/ARDUINO-WIRELESS-HOME-SECURITY-SYSTEM/?ALLSTEPS
Laser cut Spherebot
If I only had a laser cutter CNC. Anyways nice write-up (and free plans) for building a spherebot with a laser cutter cutting out the parts. Most of these I see are 3D printed, or hand built. Wish I had … Continue reading

You can get some good parts out of an old lighter
Never thought about the parts in an old lighter for re-use. After watching this video I am. http://www.instructables.com/id/Reusing-Dead-Electric-Lighters-for-fun/
OwnCloud, opensource for a private cloud storage
After wondering about cheaper, and more in control ways of putting data in the cloud, I stumbled on an opensource project to do just that, called owncloud. It looks pretty simple to use, and there are instructions on how to … Continue reading

Cheap laser cutters and upgrades
I was reading the bottom article on DangerousPrototypes today, and it got me thinking about how to upgrade some of the cheap laser cutters you can now get for $400-500 dollars (and cheaper). And doesn’t hackaday have an article on … Continue reading

Using a pressure sensor on an arduino
Actually a pcduino, but this could apply to regular arduinos. Its a write-up and sample code on how to use a basic pressure sensor. Worth looking at if you are starting out with the stuff. http://www.instructables.com/id/Use-pressure-sensor-on-pcduino/

Building a Rubber Band Gatling Gun
This is a very well done write-up on building a hand cranked rubber band gatling gun. A while back I mentioned on for $100. But this is much better and you can build it with kids. Roughly, I think the … Continue reading

Nice write-up on using GBRL for CNC
I have heard of several folks using GBRL, arduino code for converting gcode into stepper control for CNC, but not too many step by step write-ups on how to do it. http://www.instructables.com/id/My-GBRL-cnc-controller-with-Arduino/
