When I was a teen, I used to salivate over all of the Heathkit ads in the teen media I consumed (popsci and sci-fi mags, comic books, adventure mags, Boy’s Life, etc). A few friends had built their own Heathkit stereos and I envied their electronics prowessm and the depth of their piggy banks. All […]
An easy-to-use 6 digit display kit updated via your computer over serial/USB connection – The USB7 expands most computers with a USB connected 6-digit seven-segment display. Supporting letters, numbers, and a range of punctuation, the USB7 benefits any project requiring highly visible information. Using common a USB cable for both communication and power, the USB7 […]
From the MAKE Flickr photo pool Flickr user [fluxa] put an Arduino board to work outputting control voltage to a DIY SoundLab synthesizer. While the PC software has yet to be released, the Arduino code is pretty straightforward – using a pulse width modulated output through a simple resistor/capacitor filter. – CVAirSequencer Project on Flickr […]
Alex writes – Just want to let everyone know about a very special upcoming Be-In Event hosted by Reed Ghazala ( Father of Circuit Bending ) in Ohio next month (Sunday Sept 7th). The location is a beautiful camp ground close to Cincinnati. There will be music, trading, camping, and good times to be had […]
At ladyada’s tea party, user mtbf0 has posted details of his RGB brain machine powered by a Boarduino. …it generates a base frequency at 200Hz. Offset frequencies of 201Hz-217Hz in 1Hz increments can be selected giving binaural beats in the range of 1Hz-17Hz. The LEDs are controlled by comparing the phases of the base and […]
The incomparable ladyada tells us: The next version of the Mintyboost is done and documented. This time it’s based on the LT1302 chip instead of the MAX756, which can provide up to 600mA (although I’ve found that with 2xAA’s it doesn’t really go past 450mA). The layout was also improved for better efficiency. The upgrade […]
If you’re interested in building an analog synthesizer then the VCO (voltage controlled oscillator) circuit is the best place to start. Oscillators form the core of the instrument, generating basic waveforms which are then shaped and shifted by accompanying components like LFOs, VCAs, and filters and then delivered to our ears as tasty electronic audio […]
