DIY electronics is all about revisions. Make something work the first time and make it look nice the second time around. We featured this Analog LED Clock last year, cosmetically it looked fine and worked great. Wellyb00t has been hard at work making a new version which you can see on his Youtube channel. Instructions and details on the clock can be found here. Via: HG Comments
We have seen DIY bullet speed measuring systems before, this DIY Paintball Gun Chronograph by Instructables user KLASH69 has been well documented and includes schematics, PCB layouts and code so you can get a jump on building your own. “The operation of this chronograph is rather simple, there are two IR transmitters and two IR Detectors, each transmitter/detector pair is placed exactly four inches apart. When an object breaks the
I had a great time meeting the team responsible for creating the Anybot Telepresence Robot. The founder of Anybots is Trevor Blackwell who was featured on Hacked Gadgets about 5 years ago for his cool electric unicycle. There was an Anybot mingling with the people in the Las Vegas Anybots suite, it was being controlled by Ian Danforth who was back at the Anybots head office in Mountain View California.
Make is going to have a live show twice a month (every second Wednesday). In episode 1 they are talking all about the Arduino microcontroller. In this episode they interview Steve Hoefer who made the Arduino gum ball machine that dispenses a gum ball when the secret knock is given. In the second video which I am guessing was just the second part of the live show Collin Cunningham shows
Mike Szczys from Hack a Day built a Ping Pong LED Clock, Mike did some nice woodworking on the box to give the clock parts a nice case to shine from. A AVR microcontroller the heart of the clock and a Maxim DS3232 and a coin cell are used to keep track of time. LEDs are inserted through a peg board and ping pong balls with holes cut in the
In the latest Electronic Design magazine there is a great article about the latest small projector chips from Syndiant. If you are interested in how the technology works Syndiant has a write up about that here. Subscribing to the Electronic Design magazine is free as long as you are in USA, Canada or Mexico. If you are in Europe, there is a special European version or Electronic Design. Hacked Gadgets
Dave from the EEVblog has a great video about measuring battery capacity. Most of us will create a product or project one day that will run from batteries and this video will help you determine a good battery match. Check out the cool Gossen Metrawatt Metrahit Energy multimeter that Dave uses to get the battery readings! I don’t feel sorry for Dave sweating in the Australian heat since I froze
