My build progress

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 :grin:

Awh thank you a lot! For now Iā€™m stuck on a stupid 555 adsr that doesnā€™t work :sweat_smile:

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

I could aye lol . I am just trying to get the stuff that makes sound to work right , not all attempts have been successful .

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 isnā€™t painted because Iā€™m kinda liking the rustic look.

Ah yes itā€™s kinda impossible to get everything to work but most of the time what you do will work hopefully :grin:

Yeah rustic wood looks kinda good! Hopefully you will post an update when youā€™ll receive your pots :grin:
You should put some LED to your envelope generator to show that itā€™s alive :sweat_smile:

Its got a couple of bright white LEDs in it to show each ā€œsideā€

When I get paid Iā€™m gonna try and order a couple of Sams modules as well as put in a JLCPCB order for some modules Iā€™ve found on here :rofl:

and so it goes , glad I have company in this rabbit hole ā€¦

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 spent the last year + , paying the card down and running it back up .

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.

Iā€™m getting into the habit of re ordering when I notice Iā€™m getting low rather than completely out of components.

Iā€™m an advocate of that too.

A practitioner? Maybe not so much.

Hahaha! Sameā€¦ I always seem to run out of 1/4" Jacks

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! 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 itā€™s just too complicated those threshold, discharge, resetā€¦ pins :sweat_smile:

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 PCā€™s.
-Strings, standard cables and things i canā€™t make come from simple luthery, art or maker projects (again less so these days)
-Like MAIW I make a list of stuff I didnā€™t 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 - Iā€™ve scored many an odd thing but in 2019 this method netted me 2 unoā€™s, 4 nanoā€™s and over a dozen other assorted pic and mcuā€™s.) 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)

Iā€™m 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 theyā€™d found.

Someone else here does fix and trade up. I tried it but after the fix I couldnā€™t part with the gear.

If itā€™s costing you income itā€™s 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 :slight_smile:.

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.
