Model 001 - free-form 'Talking Clock'
 | 'Model 001' is a free-formed 'Talking Clock' with a strong 'Star Wars' audio theme. It also acts as a complete MP3 player. The clock was designed as a gift to my son and reacts to a set of dates and times specific to him. An hourly chime function announces the current time using my voice and personalized messages to him. The clock is interactive, providing a text-based interface and menus, accessible over a serial Bluetooth interface. To keep the interface secure, the clock uses a one-time password login scheme, using its OLED display to present the required login code needed from the user. The menus hide many personal 'Easter Eggs', waiting to be discovered. It reacts to good and bad input with contextual 'Star Wars' sound effects. The clock's main structure is built using 2mm copper welding rods, 0.8mm brass rods and 20 AWG bare copper wire were used for wiring components. The clock's electronics are commonly found electronic components, such as a Raspberry Pi Pico RP2040, a DS3231 RTC, a HC-06 serial Bluetooth module, a DFPlayer Mini MP3 player chip, a small HW-404 amplifier and a 128x64 SSD1306 blue OLED display. Two 4 Ohm / 3 Watt speakers are connected to the HW-404 amplifier and provide a crisp audio ouput. The square wooden base of the clock provides illumination, thanks to an RGB LED as well as power for the clock itself. The firmware for this clock was written in Go / TinyGo, along with a pure Go driver for the DFPlayer Mini MP3 chip. [link] [comments] |
My highschool EE project
 | This is my highschool electronics project, made this at around 15 years old it uses Binary adders, counters and cimparators and has alarm and time adjustment [link] [comments] |
Ben Eater 8-bit CPU using Logisim simulator
I just finished the Ben Eater 8-bit CPU implementation using Logisim. I had a ton of fun doing this and being a mechanical engineer, I learned a lot. I'm planning to do extend this to have dedicated data, address and instruction bus in the next design. God, I love how CPU works.

I’m building a VFD clock from scratch using only jellybean ICs
 | On the photos you can see the display module I made hooked up to my Arduino. I’m working on the boost and MCU board now, this is also my fist PCB design and I’m so proud of it! More infos, pictures and gerber here [link] [comments] |
I tried to make a 1-Bit Computer. It is super super primitive 💀

I’m distributing the Garber files of the vfd clock

Behold!
 | ...My stuff! Primarily second hand, ham-swap things and bobs, apart from the soldering iron and the power supply up above the bench. All things restored and repaired myself since I was a scrawny 15 years old with a soldering iron and lots of patience. Bench surface (way tidyer than usual) Partial workshop area (sorry for the bad lightning) [link] [comments] |
Is it too late to post my workbench?

Hobby bench for a recent EE grad
 | The little 3D printed component storage drawers are awesome for resistors and capacitors and stuff. I have a hot plate and air gun and microscope not pictured for when I do SMD work but thats not super often right now [link] [comments] |

My first breadboard!
 | My first ever breadboard kit arrived today and this is my first circuit. I'm a full grown adult but still jumped and smiled like a kid when it actually turned on! [link] [comments] |

Free (and Open Source!) Electronics Part Inventory Software
Hi everyone,
I recently published the first version of an open source project I've been working on. It's an electronics part inventory software - completely free and open source (https://github.com/PartPilotLab/PartPilot). I've originally made it for my brother, as he was f*cked up with ordering parts he already had or noticing that he actually doesn't have the part while assembling the project. All existing solutions were either expensive or shit. So I made an alternative. It has pretty much all the most important features and directly integrates with LCSC (but still lacks a bit).
Would love to get some feedback and maybe some of you would be willing to contribute :) Leaving a star would also mean a lot ✨

Brought back old VHS camera using USB C
 | It looks a bit like a pipe bomb But there is a purple trigger board taking 12V from the power bank, and a step-down converter turning it into 7V for the camera. I also had to add a capacitor because while opening the cassette bay, the camera was turning off. It looks really bad, but I'm out of home, next week I will 3d print a case for all the electronics.
