Please see my "first project" on how to setup everything: https://hackaday.io/project/175642-a-first-fpga-project-spi I used an Intel MAX10 FPGA (10M08SAE144C8G), and then a ATMEGA256RFR2 to interface with the FPGA over SPI. The ATMEGA256RFR2 is...
A search for related projects I always start out new projects be making sure I don't re-invent the wheel. A quick check of ongoing Hackaday (and other) projects returned many examples of visual spectrum analyzers. Some of them are simple LED strips,...
Today, after several months of waiting, I received a Si4732 chip. That was the reason for the new video. The previous video describes the same Radio receiver, but made with Si4730 Radio module, which due to the limited capabilities...
Battery ChargerBattery charging is managed by a bq24075 IC from Texas Instruments, with the following features: Maximum charge current configurable through a DIP switch: 1A, 500mA, 100mAReverse current, Short-circuit and thermal protection.Dynamic Power...
Hi everyone! This is a brief(ish) summary of our smart buoy project. We’ll break down the technical build into separate posts, to explain: electronics, 3d print, and dashboard. Step 1: What does it do? The sensors on board the smart buoy enable it to...
Introduction With the emergence of low-power IoT devices with cellular connectivity and the phase-out of 2G (with only T-mobile supporting 2G/GSM until 2020), everything is moving toward LTE and this has left many people scrambling to find better solutions....
The mini µmixctrlr plan the mini µmixctrlr is taking shape. by lack of a project box at hand.. roll your own box. keep it simple was a given to use discarded tech is a must in this age of resource shortages. to the chagrin of the maker community...
My solution for a cheaper 5K monitor was to just order the panel that comes in the 5K iMac and which is also the same panel that comes in the LG Ultrafine Monitor. From the same store I was able to buy a driver board that would power the panel and...
Our story begins somewhere in the year 2007, the actual date isn’t as important as that of the event occurring. For it was on this day Brian O’Connor (KA2CGB) made a trip to Ohio to visit a friend. It was at this time Brian became in possession of a...
This project has been an adventure of the most ridiculous sort...At the time I started this project-page I planned on emulating an 8088 in an AVR, so the AVR could be a drop-in replacement for the original CPU in an IBM PC/XT clone. The discovery that...
Motivation So I got a new audio receiver. It was from my local FreeCycle listserve. I use it to take the audio from my TV and power some outdoor speakers which come in handy for parties. But since I'm not employed right now, I didn't want to pay money...
The goal was to build a cheap circuit that would play a small audio file in an infinite loop. I could have used one of those postcard circuits they sell on Ebay and make my life thousand times easier but what would be the fun in that?The project required...
This project began several years ago when I got a multi purpose machine kit. The kit allowed you to build various machines including a lathe and milling machine. Obviously I wanted to automate the kit but I knew nothing about CNC or CAM software.Most...
The standard operation of this device is to give the standard pulse to the speedometer as long as there is no deceleration measured. If there is a deceleration, a series of pulses will be generated that shows for 100 revolutions of the wheel...
The project is wholly composed by off the shelf components: ESP-01ArduinoDS3231 RTCNeoPixels5V to 3V3 regulator The ESP-01 creates a hotspot and serves a page with a form and a button The Make it Glow button maskes the ESP01 send the string typed ...
