Ashish Derhgawen has built a Computer Controlled Wireless Robot. It uses some linked together off the shelf electronics to get the job done. The vehicle that is being controlled is a Microbric Viper which is normally controlled via IR light. “I’m using a 1/4 wave monopole antenna (6.8 inches) with the RF modules. It’s just a single core wire. The range I get is amazing. I think I get about
How much data has your router passed? No idea right, well check out this LCD Router Traffic Counter project if you are curious how many bits have passed through the mystery box. “Using my python library as a reference for how to use the display, and my XML parsing script for ash, I was able to cobble together a working project quickly.”
This Geiger Counter USB Hack takes an inexpensive Geiger Counter and makes it able to output counts our via USB. This would be very helpful when you want to take readings logged over time. It uses a small microcontroller to interface to the computer. Check out the small circuit implementation above! “The Kvarts DRSB-01 (Кварц ДРСБ-01) is a simple consumer Geiger counter. It does not feature a display of any
Touch sensors are getting more and more popular these days especially since many low cost microcontroller have them built in. If you have a controller that doesn’t have built in touch sensors there are many chips that do just that. The Freescale MPR121 is one of these chips. This MPR121 Touch Sensor Controller Project will give you the pointers you need to get your feet wet with touch sensors. “This
If you know someone who is starting out with electronics and wants to learn how to solder this Soldering for Beginners guide (PDF) by Mitch Altman, Andie Nordgren and Jeff Keyzer is a great start. Via: Tinkerlog
This Audio Spectrum Analyzer Kit looks like too much fun. I remember back in the 90s I had a huge spectrum analyzer with lots of knobs, buttons, levers and dancing LEDs. With the lights down the display was as mesmerizing as a lava lamp. But just like my lava lamp the EQ was phased out. There is lots of technology packed into this kit but unless you can solder surface
Having a cool tool like a CNC machine is great but unless it can make something that looks fantastic it is as valuable as a paperweight. The Egg-Bot is a interesting machine which has a limited functionality since it is designed to draw with markers on Eggs (or egg shaped items). Eastern Eggs has designed some crazy designs which really showcase the capability of the machine and WOW do the
