Printable wire stripper lights up when you hit the conductor

The image above shows an Electro Wire Stripper that might be very useful for all of us.

 “For years we’ve used razor blades to do this, as the tiniest wires don’t have a slot on our trusty wire strippers. But often we cut all the way though the conductor (or many of the strands) when doing so.”

If setup correctly, it can be very precise and give feedback telling when the blades have cut deep enough, and this is how it could be used:

  • Sight down the blades.
  • Align the blades with where the wire should be stripped.Move the wire into the blades having the blades cut into the insulation.
  • When the blades cut through the insulation and contact the wire the LED will light.
  • Spin the wire or the tool to cut the insulation completely around the wire.
  • Remove the wire from the tool and pull off the insulation.

This is a really cool and clever hack! What do you think?

How to design a Homemade GPS Receiver


Have you ever thought about designing a GPS Receiver? It seems very complicated but not with this design we found at, the article clearly explains how to make a homemade GPS receiver and we thought you guys would find it very useful.

“…I was motivated to design this receiver after reading the work of Matjaž Vidmar, S53MV, who developed a GPS receiver from scratch, using mainly discrete components, over 20 years ago. His use of DSP following a hard-limiting IF and 1-bit ADC interested me. The receiver described here works on the same principle. Its 1-bit ADC is the 6-pin IC near the pin headers, an LVDS-output comparator. Hidden under noise but not obliterated in the bi-level quantised mush that emerges are signals from every satellite in view.”

The article is complete with source code, resources and more so that you can start making your own GPS Receiver!
