Axocontrol build with OLED screen mini-documentary


#1

Hello friends. I recently documented the experience of building an enclosure for the Axoloti Core, Axocontrol, and an OLED screen, and even though it's small potatoes compared to the types of projects I see others around here creating, I still wanted to share it because I am very happy with the results.


Please take a look and enjoy, if you should be so kind.

You just provided my tea-time entertainment, and a job well done, looked very nice once the matt finish had gone on :sunglasses:

That's a nice helping-hands rig you have there as well, looks sturdy!

Great job. Had planned on doing a similar enclosure and it looks like too much hard work for a lazy sod like me. :joy:

Great video! I have watched it several times in preparation for having a second go at building my Axocontrol. Messed up one kit with poor soldering. In the video, you talk about finding out that a lot of the connections on the 40-pin connector are superfluous. Have you got a list/diagram you could share which shows just those pins that are actually used by the Axocontrol board, please? That way, I don't need to solder those connections that are unused. Thanks.

Thanks for the link @tele_player. My understanding of schematics is a bit basic but do I take it that any of the pins in the 40-pin strip that don't have a label are not connected to anything within the rest of the pcb and therefore don't need to be soldered?

How about any of the connections that don't feature anywhere else in the schematic? For instance, PC4, PC5, PB6 and PB7 only seem to appear on the 40-pin connector and don't seem to be linked to any of the other components. Can I leave those unsoldered too?

Thanks for your help.

Another way to look at it. All the identifiers around the pots, switches, etc. NEED to be soldered. So, I’d print the schematic, and use a highlighter to mark all the pins on the connector which are referenced elsewhere.

Actually, I’d suggest careful soldering, rather than trying to solder minimally. You might want to buy a bag of connectors, and some cheap boards, and practice. I can’t imagine botching one of these, but I’ve been soldering forever.
