When Roamer's bumper is depressed, there are five possible "backup and turn" scenarios--the activation choice is random.After 30 seconds of forward movement (stuck spinning wheels without depressing the bumper or long distance), she backs up and tries...
The deadline for HackadayPrize 2021 is fast approaching.Thanks to your help, I was able to post the video and I was able to fulfill all the mandatory requirements of the contest. In my video I put speech in Japanese but it has also English subtitles....
In past projects I've had raging successes by just looking at the raw data, XORing stuff together, and maybe squinting my eyes a little. Spoiler: Not so this time. I'll walk you through the steps anyway.---------- more ----------What we know: Data comes...
As the amazing online GPRS Weather Station project continues, we have yet another upgrade to the vast array of sensors with a professional analogue wind vane, kindly donated by Vector Instruments. This device will eventually be hooked into the new, upgraded,...
First up, the latest revision. Small changes from the last version including tightening up various current loops in the buck converter and moving the battery-side transient TVS diode to the anode side of the reverse-polarity protection diode to...
Today, i rewrite a code of ambient light of arduino module applied FastLED library carefully. Why? there are 3 important thing, 1) the legacy code of adalight is based on SPI that is used by a RF module too. I think move pin in code of adalight from...
There are several translation routines found during the file sending stuff that translate one character value into another one. Some we understand, like this one:F4DC sub_F4DC: F4DC 84 7F anda #$7F ; reset high bit F4DE 16 tab F4DF 4F clra F4E0...
2020-11-16 Downloaded libft4222-linux-1.4.4.9.tgz and unzipped it. Ran the command: sudo ./install4222.sh and got no complaints. In the examples/get-version.c file, there are instructions for Linux: cc get-version.c -lft4222 -Wl,-rpath,/usr/local/lib...
After I convinced myself that the emulator was probably OK, I turned back to the ROM. But after I found yet another ROM image online, and it turned out to be identical to the other three, I have to rule out bad ROM as well. Just as well as I was...
SATA StatusAfter weeks of painful debugging. I have been able to read and write to the hard drive!I ran into an issue though... the speed at which I can communicate with my FPGA to/from my computer maxes out at about 16MBs and the hard drive reads/writes...
This is a big question, where to start with the ESP8266. There is the official SDK path, for the brave. There is the Arduino, Espruino... Well, I tried NodeMCU. Starting with this page https://nodemcu.readthedocs.io/en/master/, there is a lot explained...
So since the Teensy++ 2.0 bootloader is not available and I'm not feeling comfortable to learn all the bells and whistles of USB communications I was looking for other options. Googling "at90usb1287 arduino" I found this https://github.com/mattairtech/ArduinoCore-avr...

In this post I want to share how I selected a suitable topology for the resistor network that will be the core of the programmable decade resistor. Although I did some online “research”, the following criteria determined my choices: Switch...
Realising that I had the simple yet inescapable choice to finally look into a strong and stable life-management system or chaos continuum, I started searching around on Friday 24th Nov when I said to myself "I feel that if I set the budget for the HMD...
