DIY Hacks

ElmGen DSP Development Tool

If you like playing with audio the ElmGen DSP Development Tool will help you with that.  It uses an Arduino to control a Spin Semiconductors development platform directly. When the dev tool is hacked it opens up lots of opportunity to make it perform in more powerful ways. “Key Features: Cross-platform development tool for Spin FV-1 effects processor Testing and production EEPROM programming capabiltiy Built-in real-time hardware simulator of FV-1

Computer Controlled Wireless Robot Build

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

Geiger Counter USB Hack

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

MPR121 Touch Sensor Controller Project

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

Audio Spectrum Analyzer Kit

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

DIY Shower Timer Logger

I remember some of the showers at campsites have timers on them, you crank the 5 minute dial to get a quick shower. When you are timed like this you are very conscious of how much longer you have before the water automatically shuts off. I was thinking that I could save tons of hot water fees if I implemented this in my own house although I never did since

PCB Milling using a MakerBot

Rolling your own PCBs is something that is great to speed up the development time when designing a new circuit. Even now that there are quick and fairly cheap board houses that can make production quality boards it still takes days instead of the hours it would take if you made your own in your home lab. Keith Neufeld has perfected the isolation method of PCB creation on his MakerBot.
