The ATtiny814 is hardly an ancient chip. It's a member of Microchip's TinyAVR 1-Series that was released in 2017 and still being developed, with the 2-Series being released in 2020…

You're correct that the ESP32-C3 is based on a RISC-V processor, but it has more in common with the other ESP32 boards than it does with the boards supported by the RISC-V version …

Good idea - I'll add a column to the tables giving the current consumption for each board.

The assembler is two-pass.

The assembler is two-pass and the labels are simply local variables in the defcode form. They are assigned the value of the program counter in the first pass, and the assembler ins…

Thanks - corrected "compact" to "compressed".

Sorry, I'd posted the link to the code in the wrong format - corrected now. Would you like to delete that copy?

This is a traditional game called "Voyna Virusov" or "Virus War". There is a version of it on Pencil and Paper Games with clearer rules, and some background history: http://www.pap…

As mentioned in the article I used Elecrow, who made 5 boards for $24.14. I accept that the unit cost will be more if you're only making one.

> What draws people to start projects with AVR in 2022? It's much easier to learn how to do simple things with an AVR than with an ARM. For example, you can configure a timer to bl…

Thank you for putting my 16 LEDs Puzzle on Hacker News! Yes, the principle is similar to Lights Out, but in my puzzle pressing a button toggles its LED and all the other LEDs on th…

I pronounce it 'U'-Lisp.

There's a beta release: http://forum.ulisp.com/t/help-wanted-debugging-ulisp-for-the...

See Porting uLisp to a new platform: http://www.ulisp.com/show?2JZO .

Yes, it currently provides one assembler function, but I plan to extend it to support multiple named functions.

Nice suggestion - I'll try it.

I've never heard of this happening before, and I can't even think of a way in which uploading uLisp could break an Arduino, but contact me directly (my email address is on the uLis…

Good suggestion!
