Mail Day Thread


Another save from the trash! Works as a power supply with voltage and current control! The multi turn pots are not in use, but I will probably find a use case :slight_smile:

I might also use the case as a mini-eurorack-case xD

Not mail, though, tsk tsk! A place for everything, and everything in its place! :laughing:

The proceeds of a board swap with @BlackDeath .

I now have enough modules to keep me going for at least another year…

Heyyy, alright! Glad they made it. Expecting to post a reciprocal shot when the mail comes tomorrow.

Kosmic Superspreader and VCDO received!

…and I have have now exceeded the limits of my first case! Literally need to move to a bigger apartment before I can order any more modules…

I’ll try and get some documentation put together for the VCDO this weekend. Have fun building them!

Cool! I do have some questions, as it looks like some of the values close to the edge have been cut off :slight_smile: - what’s the thing right next to the power connector? I just see a box with no label.

Oh - don’t do anything with that - I add that to my modules as an easy way of testing the power connections and getting a grounding point for the scope etc.

The 10k resistor between the 2 regulators is optional - only place that if the -5v source is erratic.

There’s no values for the trimmers on the board or the KiCad files. RV4 is 50k, RV5 and RV6 are 20k.

Any other questions let me know.

Cheers

Could you please explain to me why I don’t do that?

I ordered some [Edit] TL431s

after watching this:

Who wouldn’t want to have an stash of electronic parts that ‘can do anything’ ?!

I have TL431s in my list of “useful components to check out some day”.

I hope you actually got TL431s, otherwise you may have bought four bags of Airnorth flights from Perth to Darwin. :laughing:

I got some TL431s in my last Digikey order. Thinking about using one in a VCO instead of the LM4040 + resistor divider for a more accurate octave switch voltage reference. I’ll have to check out the video, if they can do anything maybe I can get rid of all my other parts.

So do I. Why shouldn’t they be genuine?
I’ll test a few this weekend.

I meant TL431s instead of TL341s. Typo humor.

Any chance that this is a software issue? I am just running the Ada fruit ssd1306 example.
