top class programmable power supply capable

Do you know, what´s a top-class programmable power supply capable of?

If you need to simulate overvoltage, slow start, fluctuations and other situations, which may occur in real life, then the TDK Lambda power supplies won´t disappoint you. Imagine a laboratory (testing) power supply able to provide a virtually any function. Switching on, drop-out, repeated switch-on and many other functions, by which we can test our […]

Tape Head Pre Amplifier

Tape Head Pre-Amplifier

Description The circuit is built around a popular Sanyo’s stereo head preamp IC LA3161. Low electrical signals from the playback heads are fed to pins 1 and 8 of IC1 via DC decoupling capacitors, respectively. Components between pins 2 and 3 and pins 6 and 7 provide adequate equalization to the signals for a normal

ytimer

ytimer

Description A countdown timer with super bright 7-segment displays that flash when the time is up, instead (or in addition to) an audible alarm. The design is based on a PIC16F886 microcontroller which drives the displays using a TLC5916 LED driver and dual P-channel MOSFETs. A rotary encoder with a push button is used for

Nixie Tube Clock

Nixie Tube Clock

If you’ve poked around the internets where electronics hobbyists collect, it is likely that you are acutely aware of our incontrovertible affinity for building timekeeping clocks.  It is similarly unlikely that you have been able to evade the plenitude of nixie tube based projects.  There is a reason for this. Nixie tubes are cool.  They

Nature inspires color sensitive

Nature inspires color-sensitive, CMOS-compatible photodetector

Researchers at Rice University’s Laboratory for Nanophotonics (LANP) have developed a new image sensor that mimics the way we see color by integrating light amplifiers and color filters directly onto the pixels. The new design enables smaller, less complex, and more organic designs for CMOS (complementary metal-oxide semiconductor) sensors and other photodetectors used in cameras.
