You may remember the Paintball Sentry Gun that we featured last year. Well the team over at The Sentry Project has not been resting, the new version of the gun software is now available on Ebay and it looks very impressive. It was very sensitive and precise before but have a look at the videos, it has been tweaked to improve the results! I wish I owned a junkyard,
I did some looking around after posting about this cool Bottle Cap Tripod and found a DIY Bottle Cap Tripod version that is right along the lines of what I would make. "Master parts list: 1 1/4-inch Stainless steel washer 1 1/4-20×1 1/2-inch stainless steel pan head machine screw 1 1/4-20 Bar Knob 1 1/4-20 stainless steel lock nut 1 lid from a 20oz bottle Tools required: Drill with
Recording live data is something that you could use very often but most of the time we live to learn without it. What is the temperature in your attic over the day or what about the pool?

We all need some inspiration from time to time. Andrew is a 13 year old from Canada who is doing some electronic experimenting. He built this stepper motor controller and single axis CNC machine from recycled parts from old computer equipment. Looks like he loves hot glue as much as I do. 🙂 All he needs now is a few more scanners to make his single axis CNC machine
About 5 years ago I bought all the equipment to make some home-brew beer, I purchased a few different flavors of beer kits and went to work. Only one batch was drinkable, but it wasn’t that good and eventually found its way into the sink. After further reading it seemed that temperature control of the brew stages is key to achieving a good result. BrewTroller is an open source
The crazy guys over at Mana Energy Potion needed a way to blow off the excess energy that is built up from selling the liquid energy. No they didn’t buy a treadmill, they made a DIY Airsoft Shooting Gallery! The list of needed items is not that bad and allowed it to be constructed for around $35. "What you need: 1 x 24" by 60" board 1 x 22"
Alessandro from 5Volt.eu has made this real simple and cool clock . The Laser Sundial Clock Project uses a Atmel microcontroller to move a servo with a line laser connected to it. The result is a single line that can simply represent the time on the wall. "This is a simple project of a sundial wherein the pinion is replaced by a line LASER I took from a LASER
