Hysteresis
12/23/2020 at 01:35 • 1 commentPlaying with Fasltad's circuitjs to create a slightly better hysteresis circuit than the default circuit. It's crazy because changing any value affects the rest of the circuit.
The main difference is the feedback resistor, and a better choice of resistor values.
I tried to reduce the current draw and increase the hysteresis, which keeping convenient resistor values and decent logic levels (at least the low level is < Vbe at 3.3V).
That's if for today :-)

Thank you Jaromir !
01/28/2020 at 23:36 • 2 commentsI received these yummies thanks to @jaromir.sukuba and it's only a tiny, tiny small part of the treasures he sent me !
Is it worrying that I now know half of these ridiculously obsolete parts ?
anyway I have enough of these to build a clock.
or two, maybe.
or a UART.
Damnit...
Thank you for liking and following my #Homemade Operational Amplifier !
