How to start hacking electronics

Click For Summary

Discussion Overview

The discussion revolves around the challenges and methods of hacking electronics, specifically focusing on a keychain LCD picture frame with multiple pins. Participants explore how to identify pin functions and share resources for interfacing components, particularly with Arduino.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Experimental/applied

Main Points Raised

  • One participant suggests finding the chip number to look up pinouts online, indicating that common chips may have manufacturer documentation available.
  • Another participant mentions the presence of black goop on the main integrated circuit (I/C) and expresses intent to magnify another chip with tiny writing for identification.
  • A participant provides links to resources for keychain LCD chipsets, including descriptions and pinouts for specific microcontrollers.
  • One participant expresses concern about the current state of hacking electronics, noting that many components are integrated into microprocessors or custom chips, complicating the process.
  • Suggestions are made to explore electronics forums, consider reading specific books on programming small chips, and check out project ideas on hackaday.com.
  • Another participant mentions the potential of Arduino projects and expresses a goal to interface an LCD with an Arduino Nano, considering the option of using an LCD with a built-in serial port.

Areas of Agreement / Disagreement

Participants present a variety of approaches and resources for hacking electronics, but there is no consensus on the best method or the current state of the field. Disagreement exists regarding the accessibility and feasibility of hacking modern electronics.

Contextual Notes

Some limitations include the potential obscurity of chip identification due to protective coatings, the variability in documentation availability for different components, and the general challenges posed by modern electronic construction methods.

got my hands on a keychain-lcd-picture frame thingy
there are 30 pins!
how do i figure out what pin does what?
thanks!
 
Engineering news on Phys.org
cool, thanks. there's black stuff over (what i suspect to be) the main I/C, but there's another one with tiny-tiny writing that I'm going to try magnifying tonight
anyone else have tips/pointers?
 
This is the worst era for hacking electronics. They've got everything tucked away in microprocessors or custom chips, or a mix of both.
If you have a dab of black goop on a chip, it's most likely COB - chip on board. That's where they glue the chip to the board, bond wires from the chip to some nearby pads, and bury the whole thing under an epoxy to protect it from the environment.
This is a very cheap form of construction, and generaly the parts die after a few years from slow contamination through the board.

If you want to get started, I'd recommend browsing the net for electronics forums, maybe buying a Don Lancaster book or a book about programming little chips, like the PIC chips. Also, hackaday.com has some really fun projects.

Best Luck

@jedishrfu, my goal is to interface an LCD with an arduino (nano came in the mail today!)
I guess i should try to find an LCD with a built in serial port?
