I write a book about old computers. Oh, sorry: I mean "vintage computers" from 80's. My primary goal is to show how one can build a 8bit computer from scratch. It means: how to set up a CPU, how to connect memories, how to connect peripheral chips, and...
We will make Knight Rider car led animation with a potentiometerWe all remember the technological car in the iconic television series Knight Rider. The most important feature of this car is that the LEDs on front of the car are constantly turn on...
Opamp circuits:Repressilator: The repressilator is a genetic oscillator (3). Here we build an electronic approximation of the repressilator. Gene expression is represented by the output of opamps U2, U3 and U5 below. Protein concentration is represented...
(Here's the complete description - sorry for some redundancy.) There are many single chip bipolar stepper motor controllers. These can supply one to two amps and work great for most NEMA 17 and smaller motors. But I wanted to control a long NEMA 23 motor...
ShockBIT is (2) small disposable electronic devices that attaches to a users wrists and will monitor hand motion and when the hand position is close to face (Above the shoulders) will emit a small, harmless electrical pulses (no more than 1 Second) to...
MP-4 is simplest CPU that you can build and run your programs, including conditional branches and a few arithmetic logical operations. As you can see in block diagram, MP-4 is an harvard architecture microcontroller.In this very first version there is...
A metal detector is an instrument that detects the presence of metal nearby. This time I will show you how to make a very sensitive, but simple to build "Inductoion Balance" type of metal detector made with the help of Arduino microcontroller...
Below are two examples of EEG toys.STAR WARS FORCE TRAINER by Milton Bradley ($30 - $50 USD)-Although it's been discontinued due to lack of sales, a lot are being sold at a low price on Amazon, eBay etc. -With this toy, you put on your EEG headset and...
PDQ_GFX Library DevelopmentThe motivation for PDQ_GFXA while ago, I noticed an article on Hackaday about how Paul Stoffregen (and crew) had optimized the Adafruit GFX SPI LCD driver for the Teensy 3.1 to achieve "warp speed" (see TFT LCDS HIT WARP SPEED...
QVGA Camera Module Arducam built the front camera module with the HiMax HM01B0 CMOS sensor, it’s a great balance between performance and efficiency. It’s able to capture QVGA videos/photos at a maximum of 60 frames per second. This’d make the board a...
First, familiarize yourself with the demonstration program that comes with the graphics LCD library. Drawing an LCARS display starts out with one large Rounded Rectangle on the screen. To get the color correct, you can choose the proper RGB color...
IntroductionThe Problem:Many people die from diseases, many of them that lurk in the body and patients only show signs of the disease when it is harder to treat the disease. Regular examinations and testing may also be impractical due to problems such...
It all started with a youtube video that shown a 3 channels dimmer with arduino. It didn't have the visual part (so you couldn't control it, it was a simple function changing the lights luminosity "randomly"), but it was a good start. Also, I found an...
