It's Wednesday, so here's my small apartment workbench. Moving to a new place soon and I hope I get more space.

A faulty memory IC caused Voyager 1 to send incoherent messages. After 5 months, scientists figured out how to work around it and restore communications.

I've had batteries leaking before, but this is first I've found like this.

Rare Soviet programmable frequency counter РЧ3-07-0001
This beast is almost impossible to carry by one person. Aside from the normal frequency counter stuff, there is a full CPU inside built on descrete ICs. Extracted boards on the last photo are arithmetic logic unit and RAM. [link] [comments] |
My first project (plant watering system)
First project I've done on my own with no tutorial to follow. Using an L293D to drive 4 5v pumps and controlling them with 4 capacitive soil moisture probes. Working pretty good so far! [link] [comments] |
2 second mistake, 30 minute botch 😖
Mirrored a symbol in the schematic for better readability, got a phonecall, forgot to mirror the signals too when I continued. Did this botch so I can continue writing the firmware whilst waiting for the fixed board to arrive. So, how is your "Revision A" going? [link] [comments] |

Rock Band guitar fix
Hey guys, trying to fix my buddy's Rock Band guitar because they go for like 500 on ebay. So there are two AAs in the battery holder, both are tested good at 1.5 volts. With the batteries installed, between the contact circled in red and both pins in the connector circled in blue, I get +1.5v. I would assume I should have +1.5v on one and -1.5v on the other. I also have 0v across the pins circled in yellow, and I would think I should have 3v. Does it sound like there's a short in the battery holder, or am I missing something here? [link] [comments] |

An RGB Microscope Ringlight

Thank you for the comments on my first circuit! Got a little carried away today. Astable, monostable and bistable circuits with a switch and some gates!
Next I want to look into making some registers, and maybe solder some cable with pins to act as a bus. Also want to buy smaller resistors, they are HUGE [link] [comments] |

Just made my first ever circuit, I’m so excited! I’ve been watching Ben Eater.

Color sensor/detector without microcontroller up-to 7 colors
This circuit can detect 7 different colors (red, green, blue, yellow, cyan, magenta, white) without any kind of microcontroller just with ldr and rgb led and bunch of ics like 555 timer that provides a clock pulse for 4017 ic so it can light up the rgb led with each pin separated from the other and shift register to save the data from the op amp which is connected to the ldr and bunch of diodes as rom memory and 7 segment display to show the first letter of the color.
