I’ve not posted in a long time so here’s a quick update on the progress of my drum machine. It’s come a fair way from the initial prototype documented in this post back in July 2012.
I’ve been using Nokia 5110 LCD screens for a while now they’re 84x48px have a built-in back-light and are really easy to use and quite cheap. Recently though whilst working on my drum machine I found myself wishing for a few more pixels. I want to show a “pattern view” of 16 tracks with 16 steps plus some additional information and 84×48 was getting too tight.
I found some time to convert my hand drawn notes into a proper Eagle Cad schematic.
This is a project I’ve been working on for over a year but haven’t had the time to complete yet. Electronics takes second place to children… 🙂
It’s a mini drum machine modelled on classic machines like the Roland TR808. My version is digital, playing samples rather than analogue and uses a single pic24 to do the work.
Here’s the firmware for my V2 lighthouse PCBs.
If you bought a PCB from me I should have already sent this to you, but I though I had better post it here just in case.
I thought I’d have a go at getting my PWM controller PCB made professionally.
