I got myself a Petzl NAO RL for (ultra-)trailrunning, wich is equipped with a USB C connetor for the battery. My first thougt: Nice, I could run it on a bigger powerbank in my backpack. This kind of works, when using a extention cord with 5 kOhm...
Building a CP/M System Disk To avoid rewriting the assembler codes for ccp, bdos and cbios so that they can co-exist in the same file. I can append the i8hex files and remove the "end of file markers". To make the hex file more readable I have changed...
Previously, while rummaging for scan codes, I was correlating known behaviour with key codes. One of those keys was the Clear File key (0x56). I forgot to post about that find, but it's still worthwhile to mention the file clearing operation...
How It Works Brief Summary I started with a well-known disassembly of Combat (by Harry Dodgson, later improved by Nick Bensema and Roger Williams). To this, I added a K-nearest neighbor algorithm that uses examples from a training dataset to make a...
For quite some time I have been thinking about the possibility to using a laptop to run all the heavy OpenPlotter and OpenCPN stuff instead of using a Raspberry Pi. The performance of the RPi is... well it's usable but it's not a pleasant user experience....
An unexpected cold shower made it clear that I need a new controller for our solar warm water heating system ("split architecture" which is typical for installation in middle and northern Europe - thanks @Saabman for helping me understand that I had...
Plascii Petsma by Cruzer/Camelot has one of the nicest looking plasma effects I've seen for the C64. Since he included the source code, I was able to port it to the Z80 and TMS9918. On top of the features in the original C64 version, I have...
In a previous log I said, "I'm not going to overthink this. Random selection from the chess openings is working.". Well I lied. I am going to overthink this. (Well at least think it.) Something I should have done when working on the opening moves was...
Having found the send speed setting, I got a bit interested in the file sending process itself. Tracing back a reference to "Sending....Press any key to stop. " text, I find sub_F013:F013 ; XXX prepare to send (flags and prompt) F013 sub_F013:...
I tried a couple of other cards and found that they have different MBR formats with no header. I noted this in a previous log. There's an offset at 0x01BE that points to the MBR. My theory is this is true for "bigger" cards. I think the reason I could...
Detecting and identifying a card As stated in an earlier log, the card insertion is detected by grounding the pin *CD. But this is not enough to make the scope believe he have a know card inside him. You need to indicate him what type of card was inserted....
In the arduino code set your WiFi credentials char wifissid[] = "ENTER YOUR WiFi SSID HERE"; char wifipass[] = "ENTER YOUR WiFi PASSWORD HERE"; Normally, the signal strength is displayed in dBm. But for a non techie person, the signal strength in terms...
