Yeah, it's not so good on this side of the Channel either :( . However, it should be easy to draw up a PCB layout for what you need. Then email it to China. Two weeks later you will have 10 boards, manufactured and delivered from half way round the World, for 5 euro. If you just want to...

Hi hippy, nice to see you back ! The main problem is not the #Slots in the 'real' Picaxe, it's the fact that the PE Simulator can't simulate them. This makes simulating a multi-slot programme very difficult, sometimes actually impossible. One of the benefits we were told PE 6 was going to have...

I started a Rubiks robot, back in 2014. ( Was it really that long ago ? ) The mechanics were prototyped with Lego, and worked quite well. The camera was going to be a simple colour-recognition chip, but I didn't get as far as building this part. My plan was to get the code working first, then...

It's only got one motor, so you would need some clever mechanical solution if you wanted to steer.

@premelec, I'm sorry to hear that you are not too well. I've enjoyed reading your posts, and have learnt from them as well. Hope all goes well for you. Cheers, Buzby

It can be streamlined even more. Put the code I wrote in a sub of it's own, maybe called WaitForSwitch. Then replace each RETURN in each of your subs with GOTO WaitforSwitch ( Some people don't like GOTO, but sometimes it's the best way. )

You can only tell if the switch has moved by reading the port !. At the end of each of your subs put something like this : do ' Wait for switch change let newval = pinsC & %00111111 if newval <> b1 then : Return : endif loop ( This assumes you don't change b1 in your sub. )

CDs don't have metadata for 'normal' tracks, but on a CD full of .mp3 files each file will likely have metadata. The only .mp3 files I've ever seen with no metadata were ones I ripped from CD years ago. Nowadays ripping software will let you add your own metadata, or it will suck it off the...

It does look to me that the BY8001 returns 8 chars of the file name, not of the metadata stored in the .mp3 This would mean saving each .mp3 with a distinct and meaningful 8 char name. This means you would need to 'silently' play each track and query the file name, maybe during a 'Please wait...

A quick read of Wikipedia about the MP3 format shows that the artist, cover art, release date, etc can be stored ( or at least it's address is stored ) in the 'header' or 'tail' of the MP3 file in a format called ID3 ( See here : https://en.wikipedia.org/wiki/ID3 ) I couldn't find any mention...

I see now what your problem is. The track music and names are unknown to you, so the PICAXE can't hold any relevant data about the current USB. If this was my project, the first thing I would do is investigate what data about the tracks is stored on the USB, maybe using a computer to view the...

If you have generated the sound files, and have saved them in a known track order, then the simplest idea would be to store the track names in the PICAXE. Then a simple lookup of 'track name' using 'track number' as the pointer could provide any text you want for each track. Or am I missing...

Sounds like an electric arc crucible, like the one I saw for making float glass.
