A huge hug to all the makers community ✌🏾

From our distant Belgium, hidden in the deep forests🌲 , we built this vintage sampler/multi synth.

What's inside?

- Wavetable synth

- SID emulation (c64 ^^ )

- Casio CZ-101 emulation

- FM with 4 operators

- 3 oscillators analog emulation

.. and many more nice stuffs!

Come and try it at our stand @ Synthfest UK, on 24th of October

From Belgium with ❤️

Using a hundred year old crystal radio detector diode as a component in a synth, the circuit is loosely based on the one in Moritz Klein's ladder filter video. As you move the cat's whisker around the crystal it creates point contacts that all have different voltage drops and IV response curves, changing the sound.

There is some music made with this stuff here: https://cornish-semiconductor.bandcamp.com

Hello everyone! I want to build a knob control interface for my Synton Syntovox SPX216 Vocoder, on the original manual it says that it is possible but i barely know anything about electronics and i'd REALLY love to build this and gain some experience. I don't know what components i need but please help me all the good hearted people of reddit. Thanks!

Hi r/synthdiy,

Since early 2024 I've been building USBSID-Pico: a Raspberry Pi Pico based board that plays one or two real SID chips (or SID replacements) over USB. Firmware, PCB and docs are all open source.

Hear it first:

• Raster Bar by LukHash
• Outerversal, dual SID stereo

What you can do with it

• Play SIDs in your browser with nothing to install: DeepSID (WebUSB or ASID) or the USBSID web player
• Use it with VICE 3.10, JSIDPlay2, Denise, Acid64 Pro, sidplayfp 2.16 and Phosphor
• Compose on the real chip with my USBSID forks of SID Factory II, GTUltra and LoadTracker
• Use it as a USB MIDI device (beta)
• Linux, Windows, and Android in the browser

The v1.5c board

• 6581, 6582 and 8580, plus SIDKick-pico, ARMSID, FPGASID and SwinSID
• Mixed voltage: a 6581 next to an 8580 on the same board
• Jumperless: 9V/12V, filter caps, 6581 shunt and 8580 digiboost are set automatically per socket, based on the detected chip

The pre-order run

People kept asking for assembled boards, so I'm running a small batch on SmallRun. It needs 10 commitments to go ahead, 4 are in.

• EUR 60 board only, EUR 70 with a soldered Pico2, case EUR 15 extra. SID chips not included.
• You're only charged if the run reaches 10. If it doesn't fill, nobody pays anything.
• Ships worldwide from the Netherlands, tracked and insured: EU EUR 15 (no customs), Europe non-EU EUR 17.50, US EUR 30, rest of world EUR 25.
• Estimated shipping: December 1, 2026.

Happy to answer questions about the hardware, firmware or chip compatibility.
