Some parts have turned up for my ETI Vocoder project. The CMOS 4006 becomes part of an interesting circuit called a Linear Feedback Shift Register.

Wish you had twisted the pot while the noise was playing….
You’ve really inspired me to get my electronics head on after a long time
2 numbers are relatievely primes if they have only one common divider, so that means they dont have to be primes, like 4 and 9
i would like to know how much it would cost me to buy one of each of the vocoder boards from you thank you gary
You are picking up encoded communications by something.
We are still waiting. One day you will unveil (so much for the "I" before "E" rule I was taught in school) the completed Vocoder.
I CAN wait. Make it right. I think that is what you are doing, and you have much more on your "plate". That "box" is going to be awesome. You always get everything right. (Aside from crossed legs). Our secret. 😉 Julian. You have taught me so much.
I'm from the Future!! Don't Solder the GREEN LED's IN!! They are too BRIGHT!! Oh, well, you already know. 😉 Love your videos, Jylian!!
I realize this is an older video, but for anyone in the US you can still get the CD4006 and CD4030 from NTE if you want to attempt to stick to the original design as much as possible.
Just found this video and instantly subscribed.
I quite like the sound you get on the second tap… it's got a low-fi techno feel to it.
I remember the ETI Vocoder and the Transendent 200… I just couldn't have dreamed of affording the parts back then but I used to like to re-read the magazine articles and dream.
I'm looking forward to seeing your work on this project.
Hello: What's the country of origin of the Powertran ETI vocoder?
HaHa! Nederland toch een beetje populair! (Use translate ;P)
Hi Julian.
I have a copy of the PDF but the main board overlay is missing, have you got a copy or are you building the main board from your own design.
In the PDF it say send an sae to modmags to get a copy, im sure that wont any more.
id love to build this project, any help would be appreciated.

Why not use the HC devices?
£1.65 including postage, how the hell do they sell it for that price! Nice videos BTW!
