New thing posted in the Electronics section: a very basic square and triangle wave generator. Schematic and some notes can be found here.

After way too much time away from electronics, I finally have something new to share. NANDulator is a simple but fun noisemaker based around two CMOS chips. Check out the demo video below, and have a look at the dedicated page for more info and a schematic.
NANDulator: a wonky, lo-fi DIY noise synth
NANDulator is a simple, lo-fi, CMOS-based noisemaker synth. It uses two IC’s, a CD4093 (quad NAND gate) and a CD4046 (VCO/phase-locked loop), and a handful of passive components. I think it’s simpl…
The sole sound source in this one is the original prototype of the Modutronic Messmaker, which has been processed with hardware and software effects.
Noise Therapy: Session 058
The sole sound source in this one is the original prototype of the Modutronic Messmaker, which has been processed with hardware (Yamaha EMP700) and software effects (AMOTA, Unfiltered Audio Sandman Pro, bx_Rooms). The revised schematic for this beginner-friendly circuit can be found here: https://www.fstateaudio.com/?page_id=30 AMOTA (Reaktor fx) can be found here: https://www.fstateaudio.com/?page_id=551 Thanks for listening/watching!
Some 13 years later, I’ve done a little revision to the Modutronic Messmaker circuit schematic. The Messmaker was intended to be a “beginner” build, and this new revision removes some complexity (and cost). The original version is also still available here and from a link on the page.
The original version includes a direct output from the 555, as well as inputs for the LM567 AM and the 555 CV in. My original thought was that these would be cool features for a beginner’s circuit, giving one easy access to some modular-style interconnectivity. However, all these years later, even I have rarely used these features. The quick & dirty nature of this circuit also means they don’t work the way one might expect with other modular stuff, which has become more common.
Another fairly simple noisebox synth combining an AM/FM oscillator configuration with an Atari Punk Console-style triggered monostable.

FSA Latcher demo – VST3i noisebox synth
Latcher is a VST3i noisebox synth in the same vein as NANDroid and XORbot, and contains many of the same features as those previous synths. The sound-generating part is something of a cross between a circuit I built called the Modutronic Messmaker (an AM/FM noisebox), XORbot, and an Atari Punk Console.
Latcher is a noisebox synth in the same vein as NANDroid and XORbot, and contains many of the same features as those previous synths. The sound-generating part is something of a cross between my Modutronic Messmaker circuit and an Atari Punk Console, in that it combines the AM/FM oscillator configuration with the osc-triggered monostable of the APC. In keeping with the logic-based theme of the previous two noiseboxes, it also includes a switchable “mod osc” that is fed into an XOR gate with the APC-like signal on the other input (pre monostable).
Here’s a little audio demo:
NANDroid and XORBot have both been updated to V1.01, with the biggest change being that MIDI note value is now available as a modulation source in any of the assignable slots, including the Combiners. This change is largely thanks to a user request.
Another change is that these and other FSA plugins will now be available from Gumroad. They are still available for free if you like, just enter a price of “$0”.
XORbot is somewhat related to NANDroid, in that it uses logical operations to generate sounds, and features a similar modulation setup and synth engine. The synth itself is finished, just working on presets and a manual.
Here’s an audio demo, starting from a preset and tweaking knobs:
An attempt to recreate Slacker’s Melody Generator in VCV Rack. Since I couldn’t find a module that works like the 4051 as a demuxer,* I finagled a workaround of sorts that seems to provide similar audio results, at the cost of more complexity. In fact, there are really 2 finagled solutions here, one of which is the 4019/DAC combo, which could be removed for a more “pure” solution.
The patch can be found here, and comes with a text file that lists the modules used.

* Note: I’m not necessarily saying such a module doesn’t exist, just that I couldn’t find it if it does– feel free to get in touch if you know of one.
