74HC595

The 74HC595 is an high speed CMOS device. An eight bit shift register accpets data from the serial input (DS) on each positive transition of the shift register clock (SHCP). When asserted low the reset function ( ) sets all shift register values to zero and is indepent of all clocks. Data from the input serial shift register is placed in the output register with a rising pulse on the storages resister clock (STCP). With the output enable ( E asserted low the 3-state outputs Q0-Q7 become active and present th All registers capture data on rising edge and change output on the falling edge. If both clocks are connected together the input shift register is always one clock cycle ahead of the output register.

Time Circuits Timepiece

“A practical-size, Back to the Future themed digital clock mimicking the “Present Time” portion of the DeLorean’s time circuit displays. Back to the Future time circuits are a bit over done around the internet, but my desk could really …

DIY Arduino MIDI Mixer “Crius HERMES V1.0”

“Hi! I am Crius and I LOVE MIDI Controllers! The last couple of years I started learning about electronics from nothing to be able to build my own MIDI controllers that would serve my needs , taste and be cheaper overall …

Display VFD48-1202FN analog style

“How to control the VFD48 display with Arduino My son gave me this vfd48 display and I did not know what to do with it. I searched on the internet for solutions, but there was none with arduino. So a …

Astronomical Clock with RTC ds3231

“An astronomical clock with 16 functions, with only three shift registers Years ago I ordered 12 7-segment displays. I wanted to make a clock that displayed the time and date. But it appeared that it took too much digital IC …

ATtiny85-Motor

“These are all the files that I used to make a ATtiny85 circuit that controls a motor’s speed using a potentiometer, and also has indicator LEDs to qualitatively show the speed as you turn the potentiometer. One thing to …

Electromechanical 7-Segment Display

“The goal here was two-fold; create something stylish that would look good when hung up on a wall, and ensure that all movements were as quiet as possible! I was inspired by some great existing projects that I have bookmarked …

DIY Arduino IN-1 (ИН-1) Nixie Tube Clock

“This is another one of the many unusual clocks you can see in some of my previous projects. IN-1 nixie tubes are relatively cheap. Nixie tube is an electronic device used for displaying numerals or other information using glow …

Nixie Clock in a Dome

“This is a Nixie clock 3D wired in a glass dome. It is made with IN-12A (ИН-12A) Nixie tubes and an Arduino nano. This is inspired from a kit I bought a few years ago. I made some modifications …
