Repair Broken IC Pins using a CO2 Laser Cutter

  Repair Broken IC Pins using a CO2 Laser Cutter_2 

 

If you have an IC with broken pins near the die normally this chip is dead but if you have a CO2 laser cutter and a bit of time you might be able to laser away some of the die so you can access the internal chip traces. Have a look at ca.rstenpresser.de for some ideas.

“Since a few of the Pads already were delaminated I decided to do a repair instead of soldering in a new CPU. For a repair I would need to get rid of the expoxy mold to directly acces the pins of the leadframe. Initially I was thinking of using a ‘dreml’ tool to remove the exoxy, but watching the Uncaging Microchips talk at 31C3 taught me that using a CO2-Laser will also work.”

Reflow Part Melting

at 10:54 am. Filed under Educational, Electronic Hacks

 

You need to be careful when reflowing parts on your circuit boards. Different plastics can lead to a bad day for you parts. If a part was just meant to be wave soldered the actual part may not be capable of the extreme heat and duration of the reflow process. Dave found this out the hard way when he was attempting to reflow a board from a TV that was being repaired.

DIY Speaker

There are easier things to make than a DIY speaker but the essential pieces of a speaker are able to be cobbled together in your workshop. It may not sound better than a $5 store bought one but at least you can say you built it with your own hands in your workshop. As Gursimran Singh mentions you might need a small amplifier to get a bit more volume out of the device but the feeling of accomplishment should give you a nice glow that the sound you are hearing is coming from a device that was built using your hands from some scrap parts.

“For this to be made we need:

  1. A cup made of paper in the last second step I would explain you to make it when not having a paper cup.
  2. Insulated copper wire (take it from old cfl or from ting-tong bell)
  3. Magnet(we can get it easily from market)
  4. AUX cable
  5. AUX cable port(get it from old radio)
  6. Duct tape
  7. Paper Sheets.”

Elev-8 Quadcopter Controlled With An Ardupilot Mega Autopilot Build

at 3:42 pm. Filed under Crazy Hacks

Wired Up_zpsc2a8mawk

 

GlassKNees takes us through the build and what was needed to get this quadcopter working. Upgrading the quad to the APM controller required a few modification such as prop rotation to work, this is just since this is not standardized.

“The GPS/magnetometer are inside the white dome, the telemetry transceiver is the little green circuit board on the left with the antenna pointing down – the board has a clear plastic sheath for protection. I’m using a Spektrum 6 channel receiver mounted to the right of the APM. Power comes from an APM power module that I spliced into the power distribution harness.”
