Our friend Daniel Eindhoven from Megavolts has been hard at work improving on the coil gun that we featured here before. The new circuit modifications allows the gun to fire every second now. The new halogen charge resistors look much cooler also. “At the moment the only limiting factor for fire rate is the charge time, this is the time the capacitor bank takes to get fully charged. This time
If you like steampunk you are going to love this. This Steampunk Wheelchair Project is a work of art, other than the obvious donor electric wheel chair platform at the bottom the unit looks like it is something crazy from the past. The sound effects really top it off. Via Adafruit and Make “What you get when you mix an 1875 Eastlake Victorian platform rocking chair with a Permobil C300
Jonathan from iTrends.dk gave us the heads up about a Denmark team who is building the Worlds most Powerful Private Rocket. Their goal is to send a person into space! Sounds like a blast, but I’m not sure I would want to be the first one to test it out. “This is a non-profit suborbital space endeavor, based entirely on sponsors and volunteers. Our mission is to launch a human
Svofski sent in a neat hard drive clock design he calls Strobeshnik. The clock looks wonderful and he has documented the entire build including how he etched through the aluminum hard drive platters to make the number cutouts. There is a full schematic and code for the microcontroller provided. “Strobeshnik uses stroboscopic effect to create the illusion of persistent numeric display. The hard drive platter has 10 digits, colon and
Carl has built some lasers that have been featured here in the past. Well he has sent in his latest creation. It is a small metal box filled with a microcontroller driven array of lasers! Thanks Carl. “My latest work using three lasers (red, green, blu-ray) combined with optics from a HD DVD drive mounted in something called an white fusion kit. I designed a driver circuit to control the
Using a bubble bath bottle Steve from BotBuilder.co.uk has made a cool Dalek Robot that is controlled using an iPhone (or iPod Touch). “The ipod sends out OSC signals over WiFi to processing which then talks over serial to my Servo Board. The Dalek moves around when you tilt the ipod/iphone. I am getting the accelerometer data out for this. I also have a turret that can be rotated and
The team over at Noisebridge just launched a Near Space Balloon with some gear on board. They got some very nice pictures along the way! It sure seems that this type of project is totally within reach these days. I think my next challenge will be to round up a team of people in Winnipeg who want to attempt this up here. Might have to wait till the snow goes
