A piece of musical history is the Maplin 4600, a DIY electronic music synthesizer from the 1970s. The design was published in an Australian electronics magazine and sold as a DIY kit, and [LOOK MUM NO COMPUTER] got his hands on an original Maplin 4600 that he refurbishes and puts through its paces. Inserting conductive pegs […]
The LM3914 LED bar graph driver was an amazing chip back in the day. Along with the LM3915, its logarithmic cousin, these chips gave a modern look to projects, allowing dancing LEDs to stand in for a moving coil meter. But time wore on and the chips got harder to find and even harder to […]
The chiptune scene is dominated by Game Boys and other Nintendo hardware, but one should never forget the gorgeous, beautiful tones that come from the hallowed Commodore 64. [Linus Åkesson] knows this well, and it’s at the heart of his work on the Commodordion. Now, he’s built an even better version. The original idea he […]
Two engineering students are hard at work on this air drum which they hope will help disabled people and people in nursing homes. Though, we think it just looks fun! Each board is its own module consisting of the electronics and 3D printed cases. The modules each contain an arduino mini, IR sensor, and LEDs. […]
We’re pretty sure there’s no internationally recognized arbiter of records like “World’s smallest full-featured polyphonic stereo MIDI synthesizer that fits in a DIN shell”. If there isn’t, there sure should be, and we’re pretty sure [mitxela]’s Flash-Synth would hold that particular record. This is one of those lessons that some people just can’t leave a […]
Leapfrog make some pretty awesome kids electronics. Especially admirable is the low cost, the battery life, and the audio quality of these devices. This circuit bending hack takes advantage of those audio circuits by turning the Alphabet Pal into your lead vocalist. The performance in the demo video begins with some impressive tricks, but just […]
There’s nothing new, ever. It’s all been done. But that doesn’t mean you can’t invent something interesting. A case in point is the Motor Synth, a crowdfunding project from Gamechanger Audio. It’s what you get when you combine advanced quadcopter technology with the market for modular and semi-modular synthesizers. The core feature of the Motor […]
[Eliot Curtis] found himself a little too close to 1960’s counterculture while restoring a vintage modular synthesizer — he began tripping out on acid. The instrument in question is a Buchla Model 100. The Buchla is a modular synth. Instead of a keyboard, it used capacitance-sensitive touch plates. This particular model 100 was purchased by […]
The ESP32 is well known for both its wireless communication abilities, as well as the serious amount of processing power it possesses for a microcontroller platform. [Robert Manzke] has leveraged the hardware to produce a Eurorack audio synthesis platform with some serious capabilities. Starting out as a benchmarking project, [Robert] combined the ESP32 with an […]
