Thinking Outside the Bubble Live-Streaming from a $350 360 camera into Virtual Reality The Ricoh Theta S has achieved much praise within the VR community as being an easily affordable 360 camera that does all the things. The camera has 14MP resolution...

For the current display, I have hacked a JT-033A : It's a decade-old device that was laying unused in my multimeters bin, because its probes were damaged.The autorange does not work in the very low currents :-( but it's sufficient for the...
Digging into SD card writes means shifting gears from the Boot BIOS source code since the Boot BIOS code only does reads. The CP/M BIOS code (CBIOS128.LST) which does the reads/writes after booting. Here's the BIOS code for writes to the SD Card: 0754...
After a longer break we gave it another try and soldered the rainbow cable to the display of another scale. This time we were very careful and did only use as much solder as was really needed. After reassembling the scale the display still worked! Also...
Here you can see the demonstration movie of binary uploading of my board!The .hex file uploading command isavrdude -c jtag2updi -P COM# -p m4809 -U flash:w:name.hex, where COM# is the port number of your system and name.hex is the name of the binary....
https://www.esp32.com/viewtopic.php?f=19&t=1746&p=8153&hilit=parallel#p8153Seems like I'm 3us late with reading and preparing my response. The posted scan looks like it takes 175us from address change to address change. Putting it in relation, an EEPROM...
The orginal goal of this project was to make a smarter & powerfull(er) serial com to my Canon X-07 (by adding support to UARTs & uSDCards).It 's now happening ...And I hope some other ideas will come soon....
The current prototype of the MicroGrid Connection Unit uses a regular 5V Arduino Nano, and an ACS712 current sensor to measure the current flow to or from the grid. Unfortunately, the Nano33 IoT is running at 3.3V instead of 5V, but the ACS712 doesn't...
There was an unofficial statement of "bonus points for blog posts" on the element14 community page for the "Hack Like Heck" contest, so that's why I'm posting my logs there and I'm too lazy to copy them over here. Wouldn't feel right either, so I admit...
I'm claiming 95% success in adding USB VCOM support right out of the box. This means the base Arduino sketch will run with USB VCOM enabled. This allows the board to be powered by USB and enumerate as a virtual com port, even with an empty sketch. In...
YAST is now for sale on Tindie. In parallel, I'm working on an RNG firmware which would provide a continuous random number stream through a virtual com interface. Expected throughput goes from 15kB/s using directly the RNG feature of the SE050 up to...
Post Mortem Well, this is the end of this project. The machine works as expected. One other problem was that I lost my boot sector twice. So I have implemented Boot Sector (for the first 8kb) Software Protection. What caused it? I don't know (other than...
So cartridges in PCjr are actually PC BIOS extensions with 055h 0AAh in the beginning and this is how they checked on boot: with step 2K it's looking for 0x55 0xAA signature and then check CRC: And this piece shows how BIOS determines which algorithm...
