Making Red Lights for Astronomical Observing

523 ThumbMike writes “While LED circuits are pretty simple by Make standards, they are essential to amateur astronomers. This is because red light affects the human eye less than other colors, allowing astronomers to see their gear without destroying their night vision.

Using an Oscilloscope

Osc1Ever wonder what an Oscilloscope is? Or how to use one? Here’s a good guide on getting starting “An oscilloscope is easily the most useful instrument available for testing circuits because it allows you to see the signals at different points in the circuit.

With a little practice, you will be able to find and correct faults quickly and accurately.” Link.

This does not syncronize iTunes with the phone, it copies music from the PC (iTunes library) to a memory card in a USB memory card reader. ” Thanks Ewan! Link.

Ingredients include a small breadboard, and a $15 cheapie usb charger cable, which when stripped of its plastic housing luckily has all 30 dock connector pins ready to solder.” Link.
