How To: Create a PCB Etchant That Automatically Improves After Each Use

Etching your own circuit boards is tons of fun, but etching requires strong chemicals to dissolve the copper plating on blank circuit boards. The normal ferric chloride solution works well, but can be expensive and leaves permanent stains. Luckily, we can whip up our own etchant at home with everyday chemicals! Better yet, our new etchant will turn an eerie green color rather than the dull brown of ferric chloride.

How To: Avoid invasive fingerprinting techniques

Ordinary invasive fingerprinting techniques, such as dusting, are prone to damaging evidence. Micro-X-ray fluorescence images fingerprints without touching them. By stimulating atoms to emit signature wavelengths of light, MXRF also provides chemical information -- such as traces of soil or saliva left in the fingerprints -- in addition to the print pattern itself. Avoid invasive fingerprinting techniques.

News: Watch NASA's Tracer Rockets Light Up the Sky with Cloud Trails

This morning, NASA launched the five suborbital sounding rockets from Virginia as part of ATREX (Anomalous Transport Rocket Experiment). Each rocket was launched 80 seconds apart and released chemical tracers that created "milky, white clouds at the edge of space." Now, I've seen plenty of bullet tracers in my life, but these are far more poetic. Take a look at the time-lapse video and see for yourself. Why shoot these tracer rockets? To help scientists "better understand the process responsi...
