Fully assembled and working Chipstomp
It’s done. I’ve assembled the analogue side of the Chipstomp and finally have a fully working device. There were no errors to fix this time which was a nice surprise. Just lots of fiddly 0805 surface mount components to place.
I’ve made a quick video of the project to demonstrate what it can do.
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.
A sneak look at version 2 with a new 32bit PIC and a new larger LCD
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.
This isn’t a Nokia1202, this is a Sparkfun Nokia 5110 breakout
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.
A stack of PCBs ready to be assembled
I thought I’d have a go at getting my PWM controller PCB made professionally.
I’ve updated the code to my LED strip driver and included a few new features.
Here’s a quick demo video.
[UPDATE 7 Mar 2011] Added input/output graph plus link to download LUT calc excel file.
[UPDATE : DEC 6 2010] I’ve had some proper PCB’s made for this circuit. More info here.
