There is alot to go through which is exciting!

I am having a good look. Inspiring.

Thank you again for your generosity making your hard work available Very Happy

Thank you so much Vladosh. An excellent variety of interesting modules.

I am excited to do some building! Very Happy

I will very much enjoy building some of them. I usually do my own etching but I may ...

Great looking unit! I like the type tape labelling where did you get the machine from? Glad you like the range with 2.2u & 1m. And of course you can use a 3 way centre off switch with 3 speeds of ...

The speed of the LFO can be altered by increasing the size of the 1uf capacitor and the 100k potentiometer.

Try a 1m pot and a 2.2uf capacitor, this should be a good start

It is important to use ...

Hi Amarello

I have not tried the 4049 Hex VCA but it looks very interesting and with a pcb design on the Paia pdf - handy for etching. Maybe helpful to note that regarding the schematic posted by ...

A very full featured LFO. Well done!

You got me wondering about what the electric druid tap lfo chip offers exactly and incase you are not aware there is a minor bug in taplfo 3 that they have fixe ...

Looks great. There will be some amazing virtual reality synths one day!

Thomas has kindly given his blessing to an excellent both 15v/12v design of his MPS by Haraldswerk that has a components board so no panel wiring. Quinie over on Muff's has ordered a set of boards and ...

Wow looks excellent. Have you tried front panel design in 3d?

Am sure you will get those issues ironed out.

Think I have seen your ribbon controller project on mod (muff's)?

Video synthesis is really interesting - I love the surreal look of some of the ef ...

That is good to know Grumble thanks for the wise tip - Hope that the creator of the microscope drill press uses dust extraction.

Stupidly I didn't think of pcb dust being dangerous. Luckily I enjoy ...

Yes that microscope drill is just absolutely gorgeous!

What a lovely really professional looking result. Good work to aspire to.

Hi Cyclic

Great that it is all tested and working. You are the man Razz

Good work. Thank you. I will get etching as soon as I have a diy space again - (should not be be too long before I sort ou ...

Thank you for sharing the layouts

I like the combination of logic functions you chose for your Analog Logic design.

Wanted to check that the inverters are separate from the logic not serial. So ...

Any ideas on how to ge a true HPF output from the Polivoks filter (rather than by deriving from an inverted signal and mixer).

Glad to see you continuing project Hubaswift! Good work!

I listened to your demo's and it sounds really good. Useful to have the ring mod and sub octave options that are not found on many VCO's. Good work Very Happy

Nice VCO!

I have also had problems with etching double layers. Getting them to match up is not easy and soldering the vias is a pain.

Looks like you have put lots of hard work into this. Good work.

HOW TO ADAPT 6N2P to 12AX7

This describes a plug and socket solution where;
12AX7 = plug
6n2p = socket

12AX7 pins 1,2,3,4,6,7 and 8 go to 6n2p pins 1,2,3,4,6,7 and 8.
12AX7 pin 9 goes to 6n2p ...
