Building an MB808 with my brother

Entries in this blog


A good hint was made from jojjelito , so I started building a new pcb with the following requirements:

- single sided, so you can fetch it by yourself

- SMD support (I never done SMD [or "SMT" how you english folks call it] before, but watching some videos It should be quite doable.

- containing: headers for lcpexpresso, DOUTs, DINs, USB for MIDI, AOUT for drum voice boards

- additonal wiring for simplifying is allowed for : IO-lines to DIN, DOUT, AOUT

VCC- and ground-lines

- containing not: power supply

I will use this encoders, because of there




-easy to get

I need to go a head and start doing some eagle stuff right now.

So stay on!

So here is a fast picture I made to show you the pcb 's - like normally they look totally different to what the really look like. They are razor sharp edged.

I am still totally happy how easy it is, after a little bit practice to edge pcb :)

Right now I need to go to bed.

Good Night!



I am Jonas, writing from germany. This blog may be a place where I put some stuff, showing the process of building my own MB808-Clone. I have to say I am not alone in this battle :)

My brother just joined in my little group of infected people. So what we do so far? We just etched two voice boards from microLarge containing the basedrum, snardrum, claps and maracas.

I although got an lpcexpresso board so I can have a look in the sequencer code running.

Write now I am developing a base board for all the user interface stuff like switches, leds, and encoders. I would like to minimize "cable salad" in the case so I 'm planning to

include all the DIN, DOU, AOUT-boards in the baseboard. I will take some pictures the next time so stay on!

have a nice day!
