oldschool breadboards

Definitely been a minute since I posted on here. Finally got around to pulling photos off my phone the other day, so here's something I've been working on. :)

This is a prototype of a vacuum tube amplifier I'm designing. It's cobbled together from circuits I found online and some stuff I just did based on tube data. First few pictures show the breadboarding process. Essentially from left-to-right it's:

Power Supply ---> 3 preamp/driver stages --> Push/Pull output stage

The big grey box is part of the power supply. It's a 6.3V 30A filament transformer that came out of an old vacuum tube computer. The last breadboard picture includes a custom volume control I made which also drives a nixie tube. As you turn up the volume, the number on the nixie will increment from 0-9.

Last few pictures are a potential layout for the chassis. Not 100% sure this is what I'm going to go with, but it gives an idea of how large this thing will be.

Stay tuned for more stuff, hopefully posting more frequently!

this is what I'm doing for my coursework rn

it took me so many hours to cut out all these wires to the right size and this is barely 1/4 of the circuit HELPPP

working on a new pedal while i’m waiting for VAB parts & etching

added a variable low pass filter since this video. and im considering having the gain stages on a 4-way rotary selector instead of a pot.

Using woodlouse logic gates in your natural circuits.

Isopods have 7 pairs of legs all pretty much the same length.

74** logic gates have … 7 pairs of legs all the same length!

Coincidence? I think not!

Clearly, each isopod contains 4 logic gates. This Armadillidium vulgare has 4 AND gates. Don't forget to connect power & ground legs & use pull-down resistors on inputs.

(best practice is to simply ask the rollie to position itself in your circuit.)

Like most natural systems. they use micro-voltages, don't use standard 5V power sources.
