A fun construction that I did a while ago. In live it really deploys bass from beyond the grave (which we don’t really hear in the video) ![Synth fan duo (1)](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/2X/d/dda5635f66e43fbe06b1a43c9d2af31b8607cd14.jpeg) Work on 12V https://www.dailymotion.com/embed/video/x6c1eqq ![synth-fan-small-circuit](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/2X/5/53700fc5b578ad5fbbf1adcc56b515226baea25b.jpeg) later I added some functions (a sort of VCA with clock in / and division clock select with a CD4040 and a reset button for syncro) ![Synth fan duo (3)](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/2X/e/ece946e7f5c5f9c6333ca81bf530c6aa17dbeba0.jpeg) Test with 4017 sequencer https://www.dailymotion.com/embed/video/x6q12i7 infact a very simple drone but I found it funny 🙂 if some like this kind of hack, I have other but I hesitate a little bit to post this kind of thing because a little far from modular (even if some modified one could make some strange modules) ---

hacks are good! (and it’s not like @lookmumnocomputer hasn’t posted silly/weird/awesome non-modular things earlier, so they definitely fit the theme) ---

yes the double spinner and with the guitar mic, i have made some “tremollo/LFO” with LDR and motor or fidget spinner, but here what is different and interesting is that it produces sound itself with speed ---

You didn’t share this idea with anyone from Gamechanger, did you?

I think this is more likely just a case of simultaneous invention. Would be something if it was actually inspired by Dud. ---

Is Dud ~~Gus~~ [Gijs](https://gieskes.nl/instruments/?file=synth-fan)? I thought he was French? 😀 (looks to me like Dud is riffing on an earlier idea, and I’m pretty sure there’s prior art for that one too because there always is 😃) ---

Gus? That dude is called gijs, and his domain ends in .nl . Gijs is a Dutch name and .nl is Netherlands, so I have to assume he’s from there ---

Ah, right, misread the handwriting, and the site is the first hit for “Gus Gieskes” so didn’t spot the mistake. Also, the second hit mentions a “Gus Gieskes (NL)” so it’s not just me 😃 ---

Someone should be working on their handwriting then, haha. Not that I have much authority in that department. ---

Well, I made the mistake so I should work on my Dutch handwriting reading skills 🙃. On the other hand, a quick peek at Wikipedia makes me wonder if you guys aren’t asking for trouble here: _“Sans serif uppercase IJ glyphs, popular in the Netherlands, typically use a ligature resembling a U with a broken left-hand stroke”_ and the article then goes on to complain about Y/y looking like IJ/ıȷ in Dutch handwriting. ---

They do look alike, difference being mostly that you put tittles on ij and don’t put them on a y. We have some confusing names for these letters anyways, as we call ‘ei’ long y, ‘ij’ short y, and y is called greek y. It’s because they all get pronounced similarly. Another difference between writing ij and y in handwriting usually is that y has an open loop and ij is closed. I’ll add a picture to demonstrate. ![image](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/2X/b/b80b1c82adcd5fc251b96ac719b2a8e653b146ba.jpeg) ---
