[ch00ftech] showed off the loot from the trip, including breadboards, perf boards, LED matrices, and an RFID reader … Read the rest
[Gil] recently wrote in to tell us about some awesome research going on at UCLA. Apparently by layering some oxidized graphite onto a DVD and tossing it into a lightscribe burner, it’s possible to print your own super capacitors; some pretty high capacity ones at that.
For those that are unaware, supercapcaitors are typically made using two electrolyte soaked, activated … Read the rest

[Bill the “Engineer Guy” Hammack] is back with another lesson in the science behind the technology we know and love, but might not fully understand. This time around he discusses fiber optic cabling and how it is used to relay data across distances both small and large.
He starts off by showing how laser light can be easily transmitted from … Read the rest
