Re: DF player

The 'new' boards are marked v0.5.1 will have to google see if they need anything different to the old..

Re: DF player

Just had a play at getting one of these to work (I had an idea for a project using one and had just got two new boards from Temu). This didn't seem to work with an Arduino - and I swapped to an esp32 (for 3.3V) and still nothing. I used the component from the above link (and a simple initialise, Pla...

Re: Esolangs - Brainf**k. Mandelbrot set as you've never seen before..

From the esp 32 to PuTTY. The flowcode compiled and then runs the brainf**k program..

Cool considering the only instructions are +1, - 1, next cell, previous cell, loop and print!

Turing complete!

Re: Esolangs - Brainf**k. Mandelbrot set as you've never seen before..

Changing the check on 'tim' in ExecuteBF to every 500000 loops gives a very nice speedup and still no wdt problems... and just tried 1000000 with a 50ms delay and all good too! - now up to 5000000 bf instructions before delay! Compiling optimised for performance (idf.py menuconfig) gives a little ex...

Esolangs - Brainf**k. Mandelbrot set as you've never seen before..

I posted a simple Brainf**k compiler a few days ago. I had an idea for a major improvement - rather than a (rather large) jump table - I would compile the jumps into the program code. Now jumps add 4 bytes per loop rather than a fixed table of 40k :-) So - with a little fiddling I got the mandelbrot...

Re: SR04 Ultrasonic Sensor

That's one good looking lab. How goes the trs-80? And where did you hire the apprentice 🤔

Re: IOT_Made_Easy - or not?

There's no power (easily) - it's the loft of an outbuilding. I don't like going up there - a couple of years ago the ladder 'slipped' an inch and snapped my little finger. Now I avoid ladders whenever possible :-( So the longer the battery lasts the happier I am - or maybe I should just go up and do...

Re: IOT_Made_Easy - or not?

Sounds good - I was going to power with 3x1.2V rechargeables as a test (not being able to get lithium batteries in the post is a pain) - I've currently got the board sleeping for 60minutes and seems good. I was hoping for a bit more battery life - and will need less frequent sampling (though now I h...
