Hello all, First of all I want to thank this great site, I could not have done it without the information found here :smile: I build couple of individual 808-voice boards couple years ago, starting with kick, then snare, and low tom drum. When I first saw a MB808 video on youtube, I knew I have to have one. This summer I thought why not build all the 808 sounds and wrap those in one case. Now I've build mid and hi toms, clave/rim, cowbell, hihats, maracas and clap. I'm still missing cymbal, but other than that, the clone works. I used Eric Archers circuits on Kick, Snare and Hihats, and love how those sound. To make toms and other sounds, I transfered original schematics to veroboard design. First tom circuit took couple hours to solder, but three days to troubleshoot :D Luckily, when I got it working, mid and hi toms are basicly the same circuit, just using different values on some capacitors and resistors. Cowbell and rimshot/clave circuits were easy, but clap circuit sure gave me the hardest time. After finishing all the sound circuits I needed a trusty sequencer, so that I have a standalone unit. After gathering some courage, I ordered midibox core, din and dout kits from SmashTV and started building the sequencer. Sequencers main UI pbc with all the buttons and leds are also build on veroboard. I have to say, figuring out connections and connecting all the buttons and leds to Midibox DIN and DOUTS was lot of work, but it was all worth it because MB808 sequencer firmware is simple amazing. I didn't want to reinvent the wheel, so when it came time to do a front panel, I drew a panel using Moogah panel as a template, so I want to thank him also. Here are couple photos from the build and video so you can here sounds and see the sequencer in action. Its still work in progress, but since taking the pics, I've build individual outs and main LEVEL amp section, so basicly its done apart the cymbal. It has ugly insides but beautiful soul
