Right now I’m thinking about a 1-knob fuzz with a couple sets of LEDs scattered around. One set for the volume setting, and one set for the output. Kind of like a twinkly starry night. I don’t know.
CHALLENGE April 2nd Challenge…. A call to this community and beyond for Autism Awareness.

Got the LM3914 figured out. It’s controlling the LEDs via a B10k pot. Pretty cool! Now to incorporate that into a pedal
Definitely bookmarking this for a future build.

The LM3914N controlled by a pot to in turn control the LEDs:

So to be honest im not sure if im going to make it before the April 2nd deadline but Im still going to submit something for this i have a really big idea that is going to take me completely out of my comfort zone....

Exactly. That’s what Robert suggested too. Now I’m trying to fit in some chase lighting that’s triggered by the guitar signal. Have no idea what I’m going.

The 2nd isn’t a hard deadline. You got all of April really. I might not even get my enclosure in time for April 2nd

Dude awesome! I’m spending like 800 bucks on equipment just for this project and I’m not made out of moneyThe 2nd isn’t a hard deadline. You got all of April really. I might not even get my enclosure in time for April 2nd
so trust me when I say I’m going all out for this!

Found out how to get some LEDs to react to the guitar signal using an LM386.
Found it in this thread from about 10 years ago and had to use the Wayback Machine to get this graphic.
DIY Guitar Pedals has a board shared on OshPark also if anyone's interested.

I had hoped to join some of the other challenges that have popped up previously on the forum, but life got in the way each time. Fortunately, this challenge came along at an easier time for me. I really wanted to do a bitcrusher of some sort, but all my breadboard attempts have completely failed. So, instead I'm slowly putting together a fuzz pedal. That's about as far as my breadboarding abilities will get me for now.
I've gone through a few different ideas so far. I started with a Jordan Bosstone and added an additional gain stage at the end. Interesting, but not life changing. Next, I started putting together something based on the Marigold schematic. That didn't last very long as I didn't have a the correct diodes. The current idea uses the basic framework of the Death Cap Fuzz.
I like how it sounds a lot. However, it is obscenely loud. I barely have the volume pot engaged when playing. I'm assuming that's because I haven't added any tone stack at the end yet and because the Szilkai pair is very powerful. Having said that, I'm basically shooting in the dark with all of this. The next steps are adding some sort of tone control, getting the volume under control, and finding what other tweaks (functional and/or just interesting) I can do to it.
Also, I have the pots listed as A100K, I'm actually using B100K as that is all I have at the moment...
EDIT: I just noticed that the hfe note has something weird going on with it. It should say ~60. I set up like that to compare with a MP35 I have in that range...

This build was done to support the endeavors of @Paradox916 for Autism. My brother has a mild form of autism and I can sympathize with those caring for someone with autism. To me, autism is a daily struggle. This project was to stretch my abilities and get out of my comfort zone. This build is...

Would you be able to post the schematic here? It’s not in the build docs and I couldn’t get to the forum. This would be a fun little board to have, but I want to make sure it doesn’t load the input (that’s why I want the schematic). Maybe @Robert would consider a utility board for this…Found out how to get some LEDs to react to the guitar signal using an LM386.

Edit: the LM3915 chip seems like a better choice for this and there are kits available online.

Here’s the image I worked from:
I had to use parallel combos of 2 LEDs in series with the lights I have.

Here a reverb I have been working on based off the Effects layouts Vorticity board (EQD levitation) with a switchable pre/post decay effects loop (Originally I was trying to find a good buffer but never quite came up with a good enough one that worked well in the pre decay position) Naming it the Echolalia for my Daughter as part of her condition has pathological Echolalia.
Many children on the autism spectrum use echolalia, which means they repeat others’ words or sentences. They might repeat the words of familiar people (parents, teachers), or they might repeat sentences from their favourite video.
When children repeat words right after they hear them, it’s known as immediate echolalia. When they repeat words at a later time, it’s known as delayed echolalia. As a result of the time delay, delayed echolalia may seem very unusual because these sentences are used out of context. For example, a child might enjoy a song his teacher sang at circle time, and then later ask to sing it at home by saying “It’s circle time” instead of saying the name of the song.
While it might be difficult to figure out what a child is trying to say when he or she uses echolalia, learning a little bit about this type of speech can help you figure out the meaning behind his or her message.
Children on the autism spectrum use Echolalia because they learn language differently.
Typically developing children tend to begin learning language by first understanding and using single words, and then they gradually string them together to make phrases and sentences.
Children on the autism spectrum often follow a different route. Their first attempts at language may be longer “chunks” of language (phrases or sentences), which they are not able to break down into smaller parts. These chunks are more grammatically complicated than they could put together themselves, and they don’t understand what the individual words mean.
There may be times when children use echolalia to soothe themselves when they’re upset or to rehearse something, and in those cases echolalia may not be intended to send a message to someone. But there are also many reasons why children use echolalia for a communicative purpose,
I hope to see some cool stuff this month! Hopefully I can get a demo of this done in the near future.
