TL;DR? It’s an analog modular logic synthesizer built in a wooden knife box. It is a “logic synth” because everything is based on boolean logic. There are no filters, no envelope generators, and all the oscillators are square waves

Analog Circuitry Lets You Blow This LED Out

It turns out that coils of 220V heater wire are also quite powerful emitters of electromagnetic waves, and that heavy-duty temperature sensors are also excellent antenna's. So today I kludged this low-pass filter on to the temperature sensor input to get rid of the unwanted signals and now it seems to work fine..

Folks that do software and analog electronics: (and please boost for visibility)

Is there an OSS tool that simulates analog circuits for signals? In particular, I want something that I can script and write expectations of the output signals for given inputs. And ideally that scripting would include programmatically adding/removing/changing components in the simulated circuit and then testing the outputs.

Thanks!

I am not buying oscilloscopes anymore but my only portable (luggable) scope recently died, so I got something a lot smaller but still vintage: this cute Sony/Tektronix 335, from 1976 I believe.

"Rat's nest" or "Manhattan Style" prototyping (or however one would like to call this particular hybrid variant) is fun to do and has some sculptural charm. Tomorrow we'll see if this actually does what it should do.

Learned about slew rates and other limitations of signal amplifiers, but got to 70V p-p maximum output swing with a -3 dB point around 1.5 MHz.
