If you decide to go with the Hammond 1456CE2WHBU Sloped Enclosure (146x102x56mm), then please print out the attached images on plain white paper. The total cost shouldn't be more than £75,- Definitely search for parts on ebay to get a good deal.ĪY-3-8910 - (1x) 40-Pin ZIF DIP IC Socket - (1x) Arduino Nano - (1x) 30cm Mini USB 5pin Male to USB 2.0B Female Socket Panel Mount Cable - (1x) Hammond 1456CE2WHBU Sloped Enclosure 146x102x56mm Aluminium Blue/Beige - (1x) 12 Position 1 Pole BBM Break Before Make Rotary Switch - (2x) Rotary Encoder Module KY-040 Clickable Switch - (1x) Resistors (metal film 1/4 Watt) 3 x 220 Ohm 3 x 10K 1 x 3K3 1 x 4K7 3 x 8K2 6 x 2K7 12 x 2K2 Capacitors (radial electrolytic, 16V) 1 x 100uF 1 x 10uF Capacitors (ceramic disc, 16V) 1 x 100nF 1 x 10nF Potentiometers 1 x 100K (Log), 7mm diameter, 15mm shaft length Diodes 1 x 1N914 Integrated Circuits (chips) & Sockets 1 x 6N138 (Optocoupler) & 1 x DIL8 socket 1 x 7404 (Hex Inverter) & 1 x DIL14 socket LEDs & Holder 1 x Common cathode, clear transparency, Tri-Colour LED, 5mm & 1x 5mm chrome holder bezel mount 1 x Red, 3mm & 1 x 3mm black plastic holder bezel mount DIN Sockets (for MIDI in/thru) 2 x 5 Pin DIN chassis panel mount female socket VERO board 1 x prototyping copper strip board 95mm x 127mm should do Adhesive labels (for printing front panels) & Film 3 x A4 adhesive white sheets A roll of self adhesive pvc clear film (to put on top of printed labels) Ok, let's summarize the materials you need to build the TB-AY-3. ![]() Of course, I am including the Arduino code, so feel free to customize the default patches. Important to understand here is that the design is monophonic (only one patch at a time). I pre-programmed 8 patches: The first 5 you can freely edit (Bass drum, Snare drum, Closed hi-hat, Open hi-hat and a bleep sound) The remaining 3 patches are hard coded (a random bleep sound, an arcade kind of video game sound and a Kraftwerk "pocket calculator" kind of random melody) You can't save the changes you make to the 5 selectable patches the intention here is to tweak the sounds on the fly (as they are MIDI-triggered) - often resulting in cool techno patterns. to generate percussion type of sounds), but it does allow you to select other types. This design, called TB-AY-3 (or Techno Box AY-3-8910) sounds best with the release-only type of envelope (i.e. All these functions are fully controllable, but it does comes with a few limitations the design I am presenting here is meant as an extension to, for example, drum machines/samplers capable of sending MIDI (trigger) notes. This chip contains three independent square-wave oscillators (great for generating chords), a noise generator, an envelope generator and a mixer. The design is centered around the 1978 AY-3-8910 programmable sound generator. This design is partly inspired by Chiptune enthusiasts building Arduino circuits to play Chiptune files and some of my own ideas to integrate the sound of early video game consoles into my synth-jam setup. Build a retro sounding 8-Bit Sound Generator and control it through MIDI. ![]()
