Great online BOM and no fancy parts. Sounds nice!

For 606BD - Eurorack Drum Module

It's a simple project, but nice to hear it work perfectly the first time I powered up.
The 606 kick isn't for everyone, and it doesn't replace an 808. But it gives personality and definition to a cheap analog kit, especially for things like a Casio analog keyboard. Great value!

Perfect for DIY Eurorack

For Eurorack Power Bus - 14

I couldn’t find anything close to this anywhere else. Works great and is well made. I bit unusual French shipping but trusted the process and arrived sooner than expected. Thanks!

Easy build, but no ready-made firmware

For MIDI8d Plus

Was OK to build, not too complicated, just remember to solder the connector befor soldering the 3.5mm jacks.
I was a but dissappointed that there is no pre-compiled firmware with useful functions, but only some examples that have to be heavily customized and compiled.

Response from David Haillant's Electronic stuff | Oct. 4, 2024
Hello Martin,
Thank you for your review.

I'm really sorry to hear that you were disappointed by the absence of a pre-compiled firmware.

This module is dedicated to builders that are relatively confident with Arduino and its programming environment. But maybe I should emphasize more on this point.

It is also difficult to provide firmware that can adapt to everyone's needs on a module and interface as simple as those of the MIDI8d (or the UC Divider).
Maybe I could help you write one that can suit your specific needs? Feel free to contact me if you want.

The sketches provided are examples of simple features. They are nevertheless functional. And since the firmwares are open source, everyone can share improvements or new features.

I also thank you very much for pointing out that the inter-board connectors must be assembled before the jacks. I will soon add a more detailed step-by-step assembly procedure for the MIDI8d (Plus) and the UC Divider, which all share this kind of construction technique.

I hope you will have fun anyway.
David

Great module!

For DM77 - Eurorack Drum Module

I bought the SMD prototype board with frontpanel. I just needed to solder some thruhole components that can be bought in most electronic stores. It was not difficult. I needed to look at the photo of the SMD prototype on Davids Instagram to see I needed to solder a jumper (S2). Very nice module with versatile drum sounds.
