Found a 36mm 3w 4ohm speaker on ebay for £5 so that may end up being the thing, we shall see

Whoops! got two wires soldered to the wrong contacts on the PI! had my scl and sda the wrong way around! Time to undo the damage then.

"Desoldered" them with the iron and a simcard tray opener, hella jank but it works!

Somebody get this guy some Meccano!!

Ha! Yeah, and some powerful, silent servos

I should re-watch weird science sometime

I ended up ordering a speaker from eBay, mainly due to convenience and yup, 3w, 8 ohms is loud enough for the task! The speaker is a little large at 38mm X 38mm but could be incorporated into some sort of collar perhaps?

I need to order the lipo shim next or some sorta battery pack, li-ion is going to be way more power to space efficient though, will do some reading up tonight I imagine.

Careful, now!! Using a cell is one thing. Recharging it without it exploding is quite another!
Good luck...

Aye, perhaps I should just walk ( connect it to a small mobile power bank ) before I run, especially whilst testing and refining the project.

Although, this could do the trick https://shop.pimoroni.com/products/pico-lipo-shim?variant=32369543086163

As could this for better space saving , one less board to wire up, along with a nicer and, more importantly, safer connector https://shop.pimoroni.com/products/pimoroni-pico-lipo?variant=39386149093459

Also, Check out this teeny tiny PKCell! https://shop.pimoroni.com/products/lipo-battery-pack?variant=20429081991

I'll probably go for the latter after I'm satisfied with how this intial prototype works and sounds! The standard pico has 2Mb of flash so upping that to 4Mb or 16Mb without relying on a micro SD card interface makes things much easier. There may be some other, smaller speakers I can use also.

I guess, that 3d printing a strong and sturdy container around the PKCell would be pretty high priority in order to keep it as safe as possible inside a collar,as it's going to be prone to bending otherwise which is really want to avoid! Ideally situated around the back, with some rounding to keep it all close, along with the speaker round the front, yay product design!

Tried attaching a battery pack yesterday, apparently it didn't supply enough juice to do anything, 2xAAs are not enough it seems, i was hoping that would result in 3v which is within the Pico's tolerances but ehhh, never mind.

It does happily run through a USB powerstick / Phone charger though which isn't really surprising.

Circuitpython continues to be a picky little thing about everything currently including the wording for a standard type : bytearray

Python is weird and I don't like it much at all.

9v Square battery? Probably too high..

cyangames
Yeah, I think I need 3 AA batteriess to being it up to 4.5Vwhich should do the job, just gotta buy another container for them I think, then see how that goes.

I've been thingking recently..... adding a screen to a pico + speaker + battery etc. == pico handheld

OK, hear me out....
Use something like Jays JSE language to code the games, that way the *could* be run from a microSD card (assuming the pico has enough ram to do such a thing) and boom! Popular gadget than anyone can build and code for!

Yeah, that would work, just add a couple of buttons and it's all good 👍

JSE would need one heck of a lot of rewriting to get it out of being stuck in a Javascript/Canvas wrapped engine. It uses tons of Javascript variable-array-key stuff, for starters.
Then you've the actual usability, too. No keyboard = severe limit. You'd have to pico+speaker+decent browser+probably a keyboard + battery, and by that point.. Most cheap phones could probably do a better job of it, if I'm honest.

I mean, I know there's the whole "Making for the sake of making" thing, but .. I dunno, that one seems a bit unrewarding!

If you wrote a better, faster, more specific BASIC like language and got it to run really fast on a small system, then that'd be much better.

Perhaps that could be a challenge for the new year? Make your own little Minigame Engine for SBCs!
