Hi everybody,

Just finished building my controller for a YM2149 synth, and thought I’d share it with you

Also cased in an old Sinclair ZX Spectrum + 128 case ( calm down - again just an empty case)

Reused the buttons and modified them with LED’s to make them look like Roland/ Sequential Circuits buttons from 80’s synth’s and drum machines

The control panel is laser cut &engraved in a black&white acrylic.

It is very similar to lemonhorse’s MB AY (YM), but uses an Atmega328 module from Wil Lindsay at [straytechnologies.com](http://straytechnologies.com) I got a while back [http://www.straytech…m\_mini-modding/](http://www.straytechnologies.com/beautiful-ym_mini-modding/)

The control is done by the Core, DIN and DOUT modules from Smash TV

I have a problem with the LED’s so if any of you can help me with some Assembler code I would be very greatful

Have a great weekend everybody, and thanks for the inspiration from all your projects 🙂

A real beauty! Well well done, and very consistent in style 👍

Did you cut the DIN and DOUT in half ?
