You know those nixie tube displays? Well, 14-year-old Spanish maker pinomelean made an edge-lit glass nixie that consists of ten etched glass plates stacked atop each other, with SMT LEDs lighting them up individually — similar to this display we blogged last year.
Collin Cunningham explains what diodes are all about, describing the history of the component, the various types, and even touches on creating your own. [M]aking this installment of the series taught me quite a few things. Prior to reading up on the diode, I wasn’t aware how closely its development was tied to the birth […]
Instructables user Kurt E. Clother shows how to make a shunt regulator out of a Zener diode.
Collin Cunningham’s videos remain golden! In Circuit Skills: LED Matrix he talks about LED matrices and how to control the LEDs with a multiplexing IC. He uses it to make a mini game machine! Many an experimenter, hacker, tinkerer, & maker have heeded the call of the mighty matrix – and it’s no mystery why. […]
June’s Component of the Month is the diode, and a 7-segment display actually consists of seven light-emitting diodes! So, why not matrix them up? Skot Croshere built a matrix out of 512 7-segment displays: he calls it the DigitGrid: The DigitGrid is an array of seven-segment displays. There are 4096 LEDs, forming 512 7-segment digits […]
Stephen Richardson of Tangent Audio built the AZIZ light ring for his Bausch & Lomb stereo microscope. AZIZ is an LED microscope illuminator that I designed and built from scratch. It is designed around a Texas Instruments TLC59116 constant-current PWM LED driver chip, and an Atmel ATTiny1634 AZIZ has 64 LEDs, half super-bright and half […]
A diode made from a semiconductor can generate electricity in the presence of light. Instructables user nevdull shows how to generate a modest amount of power by arranging four 1N4148 diodes in parallel.
