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
Here is a nice DIY Single-Ended Tube Amplifier design with a bit of Transformer inspired artwork made from some painted copper clad board. Thanks Gio. “For the circuit I used home made (hand etched) circuit boards, but the tube amplifier is so simple it can be easily connected with point-to-point wiring, especially if you choose to heat the tubes using AC. The LM338K is mounted (with electrical isolation) to an
Anna Ceguerra has just completed work on Arkanoid which can be played on the uOLED-128-G1 display. If you want to have a look and give it a try all the code has been provided. “The ball bounces off walls, rectangles and the platform. The code and images work on the uOLED-128-G1(GFX). This is not meant to be a faithful replication of the original game.”
Here is a cool Drumming Robot that can carry a tune. There is a long list of improvements that are slated to be added including voice control! We will have to keep our eyes on this one to stay on top of the build progress. “Robot Info Actuators / output devices: 4 hacked servos for driving, 2 servos for head movement, 2 modified servos for drumsticks 1 doorbell for ticking
If you have had your computer fall asleep at the worst possible time before you know how frustrating it can be. Todd Harrison from Toddfun.com has come up with a solution. He built a simple battery operated Keyboard Keep Alive Circuit that he stuffed in a cute candy tin shaped like a Wiimote. This circuit closes a relay contact every 25 seconds. Next he connected an interface jack to his
This Autopilot for Aerial Photography slide show that was done for Barcamp Antwerp looks really interesting. “The autopilot has a built in mixer. On first use you need to tell the autopilot what the channel and mixer arrangement of your transmitter/airplane combination is. To put the autopilot in calibration mode, switch on the transmitter, put all sticks in the center and switch channel 6 to “ON”. Now turn on the
This Coffee Can Clock is a nice piece of work, there is a good build log and tons of details here at the Wise time with Arduino blog. “The electronics is based on Wiseduino (Arduino clone with DS1307 real time clock on board), with a LED matrix shield sitting on top. The shield is built with 74HC595 shift registers that drive two bi-color (red, green, and orange by subtraction) 8×8
