You should do it! You also could make a module that control the 3 colours of the LED strip with control voltage, something like a MOSFET for each red green and blue channel š

Awh thank you a lot! For now Iām stuck on a stupid 555 adsr that doesnāt work š

555 adsr. Been there. Attempt number 3 worked. Keep going. You know what youāre building. Take it a piece at a time. And ask whenever you need to.

Bit of an update on my build progressā¦
Got a dual AD/AR on the bench at the moment waiting on some 1M pots.
Case still isnāt painted because Iām kinda liking the rustic look.

Ah yes itās kinda impossible to get everything to work but most of the time what you do will work hopefully š

Yeah rustic wood looks kinda good! Hopefully you will post an update when youāll receive your pots š
You should put some LED to your envelope generator to show that itās alive š

Its got a couple of bright white LEDs in it to show each āsideā
When I get paid Iām gonna try and order a couple of Sams modules as well as put in a JLCPCB order for some modules Iāve found on here š¤£

I made the decision to JFDI over Xmas and have spent so much money on components etcā¦
Luckily I can save a bit by 3D printing faceplates and by finding bargains on eBay

Yeah making modular needs so much moneyyy!

My no.1 recommendation is buy things like Transistors, Resistors and Diodes in bulk. Theres huge savings to be made there in the long run.
Iām getting into the habit of re ordering when I notice Iām getting low rather than completely out of components.

Iām an advocate of that too.
A practitioner? Maybe not so much.

Never underestimate what you can do with a 555! Have a look here: an Arduino Uno lookalike made by someone who took the paradigm [You should have used a 555!](https://hackaday.io/project/176844-trollduino-v10) further that you would think possible.

Haha trollduino! The idea is amazing! But yeah I know you can do lots of things with this chip but oh boy to me itās just too complicated those threshold, discharge, resetā¦ pins š

I have had a couple of spending rules that have served me well for years.
-New instruments only come from gig money.
-New recording gear comes from writing material for other musicians (not so much these days) and a flat rate for recovering PCās.
-Strings, standard cables and things i canāt make come from simple luthery, art or maker projects (again less so these days)
-Like MAIW I make a list of stuff I didnāt buy. (Amazing how little time has to pass before I cross something off)
-Passive components I salvage or beg for (an old timers blag from way back is to ask large companies for samples - Iāve scored many an odd thing but in 2019 this method netted me 2 unoās, 4 nanoās and over a dozen other assorted pic and mcuās.) I also have a permanent search on eBay for a broken vacuum solder sucker.
-project guitars are paid for with a penny jar. (Most expensive was Ā£20)
Iām Scots and we have a reputation for miserliness. That and electronics; my great great grandfather and his brother invented copper wire while fighting over a penny theyād found.
Someone else here does fix and trade up. I tried it but after the fix I couldnāt part with the gear.
If itās costing you income itās a habit not a hobby. Get salvaging and scrounging.

I had a productive weekend. While testing my envelope follower prototype I found an error in the pcb-design, so I needed to rewire one of the op-amps a bit. Although it is an SMD-type I found it not as difficult to handle as I had thought š.
After that I found all of them to work as planned. The image below shows an input signal and the output signal of one of them. Note the top signal is the dry input signal (comprising the full signal spectrum) while the signal below is the envelope triggered by the 2kHz band from the B914 filter bank only.
