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.

Rare Soviet frequency standard clock (Ч7-3)
 | Managed to save this from the dump yesterday. The thing apperas to be extremely rare as there is no info on it even in Russian internet segment. No ICs inside, only transistors. [link] [comments] |

Finished my first project
 | I made a AND gate on a through hole board. Took a while (1hrs 30 mins) but it was worth it. Try to guess how old I am. (Hint): under 20yo. [link] [comments] |
Workbench Wednesday anyone?
 | I’m 14 and this is my electronics setup. Got into it about 2 months ago and fun fact, I did my first soldiering job today (just soldered some pins onto an rfid scanner) but it was sooo fun!! [link] [comments] |

I ordered a "few" boards
 | I don't know how to program any of these chips but it's better to be curious than smart. I just ordered different ones to see what they can do. All of these boards are new besides the Wemos board. [link] [comments] |
Is electronic engineering dead?
If we consider only circuit design for PCBs, almost all the complexity is moving toward integrated circuits (chip and modules) and/or in code for FPGA or microcontrollers/microprocessors. The role of hardware engineers is still important, because of PCB layout and BOMs, but from the hardware design point of view is almost all already done, just pick a component, read the datasheet and copy the reference design. I’m simplifying, I know, find the right component is not easy at all, but it seems the hardware engineer role is just reduced to search and connect modules. Only ICs designers delve into the complexity of hardware design. Do you agree with me or can you explain why I’m wrong, pls?
My question arise because I’m considering whether or not to move to hardware design from firmware. Currently I’ve a master in EE but I’m working as a firmware designer for microcontrollers.

What is this module ?
 | Hello everyone, could someone tell me where I found the datasheet for this module "Mitsubishi J2-Q03A-D" I can't find it on the Web, very possible it's an IGBT, I want to know what's burnt too Thanks [link] [comments] |
I present to you: the speaker
 | It even comes with a light if it's too dark. Incredible! [link] [comments] |
I present, the mini altoid tin speaker
 | It may look small (ring for scale) but it sure is mighty with a max volume of 110db. I 3d printed a case too. What do you think? [link] [comments] |

Some idiot (me) forgot to update copper fills after adding these plated mounting holes, shorting 12V to GND. Dremel to the rescue!

100 LED chaser
 | I like building useless gadgets and this was my latest. It uses a 555 and 2 X 4017's. I originally found a circuit on the internet, and modified it so it would actually work. (Something found on the internet is totally wrong? -Never!) It now hangs on my workshop wall, constantly powered by a solar panel/battery. I ordered 100 blue LED's and got sent 95, that's why theres 5 odd ones. [link] [comments] |
