Historically, getting files on to a microcontroller device was a fraught process. You might have found yourself placing image data manually into arrays in code, or perhaps repeatedly swapping SD cards in and out. For select Arduino boards, that’s no longer a problem – thanks to the new TinyUSB library from Adafruit (Youtube link, embedded below). …
For my latest project, I am diving back into Verilog to create the hardware side of Consolite. For those who don’t know, Consolite is the name I’ve given to my design of a tiny hobbyist game console and associated software toolchain. In my previous posts, I demoed a compiler that translates from a flavor of …
ulibSD It’s a library for use SD cards in SPI mode with uControllers, entirely writtenin C. This library can work with SD cards and also has the possibility to emulate the behavior in a PC file (GNU/Linux) using the macro _M_IX86. It’s for debugging purposes. The data transfer is oriented to 512 byte size, remember …

I always considered circuit boards like this something you bought, not something you made. Not any more. I actually helped to make the board in the picture above. And it was awesome fun. The board is designed to monitor the conductivity (and, possibly, contamination) of water in lakes and streams, with the wonderful feature that …
The goal of this project is to learn as much as possible about the Zsun WiFi card reader and run OpenWrt on it to turn it into an awesome wifi device. UPDATE 2017-09-12 Info about LEDE and USB gadget working UPDATE 2016-11-28 Adding some more info about the new PCB revision, thanks to Erik Dorner, …
This project, builds on Wunderground weather forecast via the Internet. Specs: 1. 3 days weather forecast (Low&High temps, probably of precipitation, condition icons) 2. Current weather conditions (Current temp, feelslike temp, humidity, pressure) 3. Current wind directions & speed with analog gauge meter. 4. Indoor temperature with Dallas 18b20 Temperature sensor. 5. NTP time via …

Story The main purpose of this project is to build a system based on chip ATMEGA328P, Arduino compatible, and interface it with a 2.2″ QVGA TFT display using the library ILI9341. As an alternative to the self-build system you can use an Arduino Pro 3.3 V/ 8 MHz board or similar. This system works well …

This project started as many of mine usually do, as a honey-do. We have compiled an extensive list of our book and movie collections on our computer at home, but my wife wanted to be able to scan the list from the video store (yes, we still go to the video store). So I created …
