I've been using various versions of ZeroPhone for more than half a year now, from just carrying one with me to pretty much depending on having it with me. I've also been thinking about what's necessary to integrate it into my life as much as possible....
This project demonstrates how precision manual PWM can compensate for the non-linearity of a human's perception of light intensity, creating multiple visually appealing light patterns, all within 1kB of program space. The application was a retrofit of...
Parameterized - IoT Confrigurator The following is intended to illustrate the capabilities of my parameterized IoT configurator with an actual use. I recently wanted to measure the temperature and humidity in my house. I live in the Dominican Republic...
2023-09-09 For some reason, it isn't working. The 32K RAM piggy-back is working, but graphics are not. It has been modified to take a 4K EPROM. Quick tests: 1 LET B=11520 10 FOR A = 0 TO 8 20 PRINT PEEK A - PEEK (B+A) 30 NEXT A I get: 128 64 32...
It's been a while, hasn't it? My work on this project has been relatively sporadic over the past 12 months. I've not found it easy to find a balance between this, my day job, and other projects I'm working on. As a result, there have been some relatively...
Building a smart (IoT) product is more an art than it is a science because it is about unifying the physical world with the digital one. When you put a piece of hardware on the web, magic happens. But one device on the web is one thing. Think about tens...
Recap In my previous post, OpenOCD-based debug support was brought up for the Ibex RISCV core. The debug core implementation is based on RISCV-dbg. Since then, having worked a bit with the debugger, I did notice a few shortcomings and opportunities for...
The 555 timer IC is an integrated circuit that is used in a variety of timer circuits, pulse generators and oscillator applications. The heart of the tutorial is the 555 timer IC that is wired as an astable multivibrator. In this tutorial, I'll first...
Nothing gets me more excited about the IoT and embedded development than the opportunity presented by Machine Learning. Case in point (and shameless plug), I've built a Raspberry Pi-based birding project, a speed trap, and an anomaly detection...
Project update:What a RIDE this week has been! Every once and a while you put a thing down into the EDA, shoot it off to production buy all the parts everything comes and the thing comes out working, EXACTLY like you thought it would! I...
As usual, I am trying to do five or six things simultaneously, and everything is important, in some form or fashion., even if for the most part, few things are actually essential. So I found a copy of the source code for the classic chatbot Megahal...
What problem are you going to solve? We run in a busy world where we find it difficult to water plants on time. It was found that gardeners used so much water in their gardens or on their balconies that they lost track of things. The result is that the...
For whatever it is worth, at this point in time - if I add up the word count for every project that I have ever submitted to Hackaday, well, right now I don't quite know if I have hit the 50,000 or even the 100,000-word mark yet. The 100,000-word...
In the last project, we saw that we could adjust the brightness of an LED using the PWM capabilities of the Atmega chip. We will now take advantage of this capability by using a red, green, and blue LED and by mixing the colors to create any color...
I'm surely not the first person to figure this out, but I didn't come across this solution while searching around. They are probably out there and I just didn't find them. The problem, in a nutshell, is how to reliably map USB devices into a docker container....
