Look, sometimes a girl-creature just needs to hack apart an old pot lid to make modular panels. I'm adding enrichment to my enclosure

The classic EPROM!

Each of these chips has a meg or so of computer memory, Only erasable by shining ultraviolet light through the top window. They were used to store operating systems in computers (and some synths), game software in arcade machines, among other uses.

In modern electronics they have been mostly been replaced with the E-Eprom, which stands for electrically erasable programmable read only memory. A phrase which I manged to impress one of my collage professors by recalling without hesitation at 8 am.

In music, you see these quite often in 80s synths. the need for stable memory was higher then in computers of the time, so they often had more rom and less ram. For example, Most wave table synths had several eproms for wave form memory.

In the 90s you see a shift to non rewritable masked proms, driven by japanese companies (mostly yamaha). these proms offer more memory per chip, and the best long term stability, but require more testing, and large production runs.

I am now taking hardware gear commissions again!☆

Shut this option down for a bit, but it's back again: everyone wishing for a piece of gear (pedal, eurorack module, full synth, ...) of varying fucked-up-ness made with loving paws of a decoracore transfem losergirl - look no further! Here's some stuff that i made.

Here's a full catalogue of my DIY module designs that i can execute for you with any customisations that you'd like. I also can take on any arbitrary hardware project that's not modular - so, pedals, desktop units, etc, are also a possibility. Prices vary and i do value my time, but also i have like half a dollar of money that's not to cover the rent, so now's your chance to get a custom cheaper than usual.

Also, all the SFP series modules from that catalog above are for sale, too - they're Eurorack format, inquire for depth, prices, and other details. All the photos and demos are attached to each module's page.

PLURR!

"PSYCHEDELIC SOLDIER" «Психоделический солдат» by SHERMAN DROZD [2022]

A Ukrainian-made, DIY synthesizer made from a reclaimed burnt-out tank headlight from the Russian war on Ukraine.

I’ve been tinkering with the korg 3DS synth every night before bed lately… it’s therapeutic

Living out the modern trans soccer mum life I always dreamed of. Soldering together a midi merger/splitter while watching the oldest compete in a SF6 tournament on twitch. Didn't even have to leave the house!

Despite some bad news that appeared yesterday, and attempts of my friends to get me out of the lab, my Friday night was almost perfectly effective, yielding the results that were planned to be gained in May.

In 11 hours I was lucky to build Two units of Serge DUSG and one Negative Slew from bare PCBs and the panels to working and adjusted modules.

I also did a successful archeological research in the field of 70th synth schematics that led me to an idea of module.

Here in Russia, we say "Give me two", if something irregular happens bringing extraordinary results . So that night was "Give me two".

It is done! Now I just gotta fill it with bleeps and bloops

I MADE A FUCKIN' FIXED FILTER BANK MODULE WITH MY BARE HANDS

and a soldering iron. AND i'm giving all the deets on it to you 4 free!

That's right. 10 discrete core VCAs, followed by 10 fixed frequency bandpass filters, all controlled by a set of macro controls like the scanner and odd/even band CV and audio inputs, mixed down using a two-bus switch-selectable audio summator. Why? Because why not to divide your complex audio source into separate tiny little bands, and then control the volume of each one in weird ways for fun? Really though, check out what feeding it some white noise and sequencing the scanner thing alone can do, with a bit of end-of-chain delay and a short envelope to all bands thrown in.

I designed and built this in about 3-4 months, but most of this time was spent sitting and staring at the box with parts in dread. This is a hardcore build, the most hardcore SDIY build i did so far. How do the GUTS look like? Well, here's how - it is a battery of PAIN built of pure MADNESS, although a fairly orderly and manageable one. If someone manages to build this, i will probably send them a congratulatory postcard and a free module.

Oops, all veroboard! Also, power and master signals delivered to them via bare wires skewering the ten boards behind the unit. What a beauty - definitely a safety auditor's dream, too! :3

This all took a considerable amount of time to wire and debug. But! If i did it, humans can do it, because i am a human. Which means, if someone really wants to, they, too, can have a cool filter bank. For this reason, as usual, i wrote up on this thing on my website. Not only what it does, but the schematic, the veroboard layouts i used (you better not use them directly and instead make them better first), circuit notes, more COOL audio, photos (although those four are pretty much it), and everything else - all this can be found out there at my cool synth website. So, even if you're just curious for more sound demos, go check it out. And i dare an SDIY enthusiast to actually pull this one off.

Anyways, now that i'm done with this chunk of wires and parts from hell, i'm going to go sleep my happy sleep of a girl who owns one vast entire extended fixed filter bank.

I made a thing! It's a DIY synth, shoved in an old junction box and given the most lurid paint job imaginable 🎨

Basically 8 DX7s combined, like a Yamaha TX816 except it cost me like 50 bucks instead of 2k

Looks mad, sounds fantastic!

Project is Minidexed, if you want to make one yourself

(You can probably make it a lot neater than mine)

Really loving this pairing of tELHARMONIC->Ikarie->Data Bender and Ts-L->Yester Versio. This patch, for the latter I cranked up the "regen" and lowered the filter, allowing it to sweep from sparkly pings to just texture depending on wet/dry mix.

The Y LFO from Marbles is slowly modulating Flux and Ikarie's Stereo parameter for more subtle movements; while Centroid, Degree, and Effect parameters are played by hand to really keep the piece evolving.

Bloom controls tH and Mables controls Ikarie, clocked at a 4/5 ratio to each other respectively, and with each set to slowly evolve their sequences over time. Simple AD envelopes from Peaks.
