Yeh!! I've built the FEITW circuit many times now. Rene should get nominated for a noble prize, this is a fantastically great sounding ADSR!!!

Eurorack copy of the Buchla 258 Dual Oscillator. Very easy to get a good sound out of this.

This particular PCB set uses the THAT340 transistor array, working off Mark Verbos' annotated schematic. I've got a set of PCBs that use BC8x7DS matched pairs instead (cheaper), and will verify them in a few days.

Arpad Benares' touch controller from Synapse Magazine. This was a pseudonym for Serge, and it's a very responsive touch controller indeed!

Provided, of course, that I don't screw up. I had three resistors in the small oscillator going to ground, and not -12V, and I ran out of 22M resistors (hence the two in parallel on the back. I also had the ICs far too close to the header pins, and had to actually slide them forward as much as the sockets would let me. To do this, I had to desolder the power smoothing caps and angle them forward a bit.

Voiced/Unvoiced Detector, built from the Doepfer module's schematics. Originally did this for someone in 2017, finally got around to building one for myself.

I think the wires for the pots was why I put it off. I can do crimped connectors... they're just a fiddly pain in the posterior to actually do, for me.

I showed that one before, but now it got a frontpanel. Design wise it is still not finished. At first sight I was really satisfied with the edges, but then I decided to try out rounded edges on other boards and I liked it more. So I will make another run of pcbs and panels I guess Laughing

Under the wire...

I used a sewing machine speed control pedal, stripped of everything except slide pot and lever microswitch to voltage control the decay of a HiHat circuit. It worked well electronically. but the action didn't feel right physically, even after I added a heel rest.

The foot plate from a damaged acoustic HiHat, some wood, rubber, and a big spring gave me something that feels more like operating an actually HH.

The microswitch can be used with circuits that require off-on/open-closed. A slide switch selects Tip and Sleeve closure, or Ring and Sleeve, as used by some manufacturers.

Great work again Alan P. If you have any PCBs left over and want to sell 'em please PM me. Thanks

Wow, that's a neat little instrument!

The leftmost bottom panel (labelled "computer") is a non-standard (USB-)MIDI unit, isn't it. Where did you get that from?

Cheers and a lot of fun!

Drum sequencer, first 4 channels pure digital, the next 4 are outputs of a quad 16bit DAC.
Module is powered by a bluepill STM32F103.

looks great grumble Smile

I have a bluepill to play around with here, what do you use for level shifting ? (3.3.V <> 5V)

For the digital outputs I just use a 74LS08, works perfectly.
For the last 4 channels I use a quad DAC which accepts 3.3 volt digital signal, and puts out 0 to 5 volt. The rest of the components like the display etc. are 3.3 volt compatible.
At the moment I’m working on the software, when that works I will open a thread with schematics and some explanation how things work.
For this project I use the Arduino IDE.
I just realise that I just have outputs and no inputs... guess I have to make a secondary panel with trigger in and outputs...😱

oh interesting, I just checked the datasheet for the 74LS08 and it says the mininum high voltage level is 2V. yeah that'll work, cool
Did you get the arduino IDE working with USB ? I did manage to upload a sketch through FTDI but haven't been able to load an arduino bootloader on it.
and yeah, I did notice the lack of inputs, and the fancy goldplated connectors Shocked

I used this set,didn’t bother uploading a bootloader.
This set cost me less than 3€ and just the blue pill board about 1€50 (less than a knock-off Nano.

Thanks.
I have one those too but since I wasn't 100% sure if it would work and didn't want to risk having to wait another month or so
I also ordered one of those FTDI boards right away, which I believe was only $0,75. But good to know that one works too.
Yeah the blue pill boards are damn cheap and with those specs a nano doesn't even come close but I do like the convenience
of only needing a USB cable and not having to mess around with different voltages and/or jumper settings.

One more question before I derail this thread too much; why the red buttons in those places, was that purely an aesthetic choice ?

I plan to have midi implemented as well, and the buttons can serve as a keyboard input (could have used black caps instead of the red ones Wink )
And the “fancy” gold plated connectors are the same price as the metal ones and are there to discriminate between triggers and analog outputs.

ah that makes sense. I was looking at it as a drum controller and it made more sense to me to use them for steps 1,5,9,13.
It does remind me of a MIDI controller I made in 2013 but never completely finished and I don't think I ever posted any photos before.
It is functional though and I used it to create some albino tracks which you can find here.
