Thank you!!!! :)

Pitch bend in the Speak and Spell can be made just connecting different pins on the board via a 1.0 Mohm potentiometer. This is the version I used: experimentalistsanonymous.com/diy/Schematics/Circuit%20Bending%20and%20Modifications/TI%20Speak%20and%20Spell%203.jpg

Thank you so much. The secret was the enormous inductors. a total of almost 7-8 H. I got the inductors from a friend who collected electronic surplus and rare components for a long time. Apparently the larger ones originally were custom made for a very early voice synthesis experiment at a University. Here's a first test of just the inductors. ua-cam.com/video/VmGu8COb88k/v-deo.html

Much thanks! :)

Several glitch/bend points exists for all the various iterations of the Speak and Spell. I found mine here: experimentalistsanonymous.com/diy/Schematics/Circuit%20Bending%20and%20Modifications/TI%20Speak%20and%20Spell%203.jpg And here is also listed more versions: experimentalistsanonymous.com/diy/Schematics/Circuit%20Bending%20and%20Modifications/

thank you so much! 🙏✨☺️

Thank you, and yes I know. Experimenting like this often has me starting with way too much headroom (might be needed for the feedbacks), I wished UA-cam added Normalizing processing for audio -- especially since e.g. Instgram has had similar contrast boosting functions for ages… but you’re absolutely correct. I’ll try and look into optimizing pre-phone better… ❤

It's a passive second order high pass filter. I used the formulas on this page: electronicbase.net/high-pass-filter-calculator/ There are some more details here (sorry for my messy schematic) lookmumnocomputer.discourse.group/t/diy-king-tubby-big-knob/7297/3

@@jacobsteel very clever ! Thanks, will experiment soon !

… and they should make a reclockable Coolaudio 1000 pedal… free pitching makes some great sounds!

Thank you! sure, fire away. I'll do my best... :) I guess droning could work, the pitch stayed pretty stable... lowering the supply voltage produced many random effects though... (also these no brand versions are somewhat more unstable than "brand name" ICs)

Haha… I’m not clear on a good Venn diagram over all forms of sound generation and manipulation… 😉

thanks! 🙏

Thank you! 🌞

thank you so much! :)

no, I run out of free space… Guess I’ll erase some older stuff and post it. Was happy with it.

Thank you! 🧹🐇🗿

thank you! 🙏🌟🙏 yes, I liked all artifacts from analog control and these really simple tape players… also, great germanium transistor distortion on older tape players…

Thank you - and funny you should mention it, repairing an old tape echo and learning more about them got me started too! 🗿🙏

thank you! yes, he’s great! 👍

thank you! Yes it took some time to align the heads - but it helped that everything is made of metal in these old machines…

Thank you 🙏

As far as I can tell - so far several recharges and hours of use… but (of course) I personally can’t guarantee anything.

Thank you! Yes, I like it a lot. It's based entirely on 741's LDR's and lighbulbs, it's Haible's board (more on his development here) jhaible.com/legacy/compact_clone/ As far as I've been able to compare the circuit designs the phasing parts is identical. elektrotanya.com/schulte_compact_phasing_a.pdf/download.html However, I haven't seen what's inside the remote to the Shulte - and the knob I added was for "Manual" (I also added an input for Expression pedal, e.g. av regular volume pedal (just takes the light of the bulbs up and down manually instead of by built in LFO). Here's how it sounds when this Expression input is controlled - via Vactrol (LED to LDR) by the trig out from a drum machine (that was more interesting than just an envelope follower) ua-cam.com/video/B2v5CDmOsLA/v-deo.html

thank you! We had great fun making it!

Setup via an external mixer. One channel has the sine input, sending to the Nagra III via send 1. The Nagra III is in REC, recording via the Mic. input from external mixer send 1. A second channel on the external mixer takes Nagra audio from headphones, feedback controlled via send 1. Hope this makes it clearer. :) The proof of concept above was mainly "does the tape mechanism pull hard enough to pull a tape via an extra loop". It's a Nagra III, best machine for tape loops: it did. <3 NOTE: I tried to just loop it in the Nagra but it that didn't work. Most of the times external mixers give better feedback control anyway (even when working with regular delay pedals, you can add a limiter in the feedback loop and have much more control etc etc).

@@jacobsteel very helpful! Thank you!

Thank you! Controlling the envelope was the key. Short pulses turned out too fast for the (regular) lightbulbs in the Phaser (which is completely based on 741, LDRs and lightbulbs... Under the hood view here: ua-cam.com/video/XDyTqbKz_lg/v-deo.html Great Phaser BTW, a recreation of the legendary Shulte Compact Phasing A (now by Haible, renamed Krautrock Phaser) More on the phaser build: jhaible.com/legacy/compact_clone/

Thank you! :) I'm erasing the tape and feeding the echo back into recording. I've tried covering the erase head with tape and that allow for some amount of layer-recording, but the recording gets so much better if you just feed it back. Yes, my Akai had the broken-cam problem. www.vintage-radio.net/forum/showthread.php?t=134714 I see now that cams can be bought here: www.wilkinsons.tv/product/akai-4000d-cam/ (but, as I remember it a few parts were missing on mine (fleamarket find) from previous repair attempts) Another video on this DIY tape echo: ua-cam.com/video/-xT16pdS3Ao/v-deo.html Here's a DIY tape delay from a cassette deck: ua-cam.com/video/OYjC2h2sVaE/v-deo.html

@@jacobsteel Fantastic, thank you so much for the links to your other videos - I'm definitely going to have to give this a try. I have a DIY built modular synthesizer and I think this will be a good addition to it! :)

thank you so much! ✨🙏🌟

thank you! :)

Thank you!

Thank you very much! The violin noisebox is getting expanded with more stuff... will post quite soon... :)

@@jacobsteel awesome! I’ll make sure to check it out when you do.
