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.

Kerbal Controller - the Basics

“The goal of this tutorial is not to show how to build a specific KSP controller, but to show many of the common design choices and their pros and cons. The idea is to guide you to make your own …

Valden: Heat Pump Controller

“The Valden Heat Pump controller is an open source platform to precisely control heat pumps. This controller can be used for the automation of newly built Heat Pumps (HPs), as a repair controller for old systems or as control system …

DIY SMU: Source Measure Unit

“As a lifelong analog EE, I have built and used many DC power supplies starting with an LM309 5V regulator in the late 60’s. Then on to uA723s, various 3 terminal linears, and many switchers. At Analogic in the …

SonicSurface: Phased-array for Levitation, Mid-air Tactile Feedback and Target Directional Speakers

“We will build an array of ultrasonic emitters. It has 256 emitters arranged in a 16x16 grid operating at 40 kHz with individual phase control. It can focus the acoustic power at controllable positions to create dynamic levitation of small …

ATtiny85 - Spectrum Analyzer on RGB Led Matrix 16x20

“Continuing with ATtiny85, today I’d like to share how to build a music spectrum analyzer on 16x20 RGB led matrix. The music signal FFT transformation and LED Bit Angle Modulation are all carried out by one DigiSpark ATtiny85. Main …

Lor’s matrix glasses

“DIY (NO PCB) LED matrix glasses using 3mm LEDs! LED Matrix glasses made with discrete 3mm LEDs using their leads as the matrix frame. I started working on this project out of nowhere and a little over 2 days later …

Rainbow Led Circuit Sculpture

“Today I would like to share how to make a sculpture circuit that controls 16 RGB leds using ATTINY85. We can adjust their colors separately according to the colorwheel rule with a touch button. The main components are as follows …

Command & Control of Multiple Serial-In/Parallel-Out ICs

“Design projects using many 100’s of output pins, using banks of serial-parallel ICs, up to 255 ICs/2040 output pins, on minimal digital pins The ez_SIPO8 Library Introduction - More from Less Arduino microcontrollers are great for offering readily usable …

A Shuttle Mission Control Mock-Up for Kids

“A Mission Control Center for children was constructed to manage a pretend launch of the space shuttle. I wanted to play-out the make believe mission with nothing but LED lamps to tell the story; both 7-segment displays and graphic displays …
