Hey everyone! I'm the creator of this. Glad to see a few of you have tried it and enjoyed it. Any questions, just let me know below and I'll do my best to answer. Just to answer some of the stuff below: Yes, you could write someth

I think there were just a bunch of other features they wanted to give exposure (ML, speaker, etc), and the kid-friendly tools out there for it won't support Zigbee. However I bet Nordic's examples for Zigbee on nRF52833 would work

Espruino (a JS interpreter for MCUs) runs really nicely on this too now - you get wireless programming and debug, and a full Bluetooth LE stack (you can run Web Bluetooth on the device and use to control other consumer electronics).

I'd like to see Apple implement Safari's missing functionality before they try and come up with a replacement for WebGL. Where are getUserMedia, MediaRecorder, WebRTC, filesystem, vibration, screen orientation, Service Workers, We

Hi! Thanks, v7 looked great too. mJS looks like a good idea - IMO it'd be nice to standardise a sane, minimal subset of JS that can be easily implemented - it'd be a huge help for all the developers of embedded JS interpreters, an

Espruino's had an FFI interface for the last 3 years! Nice to see they did their research :)

I get this too - thought it was just me/my family. I never seem to actually 'dream' the answer, or know what it is ahead of time. It just seems obvious when I look at the code again later, and I totally rely on it now. As oth

Oxfordshire countryside in England. I tried working from a small flat in London and I got totally burnt out. I like being able to look out the window and see trees, fields and a river - I've been working full-time for myself for 7 year

Thanks! Yeah, the phone apps that do it turn on the phone's flash and it works much better - but I can't find a way to do that from JS. It seems like one of those things that's in the pipeline but hasn't made it in just

I'm under NDA, but I believe we can talk about things that have already been disclosed. If you do a google image search for large micro:bit images, you'll see there's a Nordic NRF51822 chip (Which is an ARM Cortex M0, with BL

by gfwilliams 11y ago
There is currently a version of Espruino for the Micro:bit too, so kids will have the ability to use JavaScript. You can even program/debug it over BLE as well :) However there's been virtually no interest in it so I haven't

There is http://www.espruino.com - where the toolchain runs in the MCU - you can then just send the JS code you want to execute straight over to it :)

There's been info on doing this with Espruino for about a year now: http://www.espruino.com/Headphone . There's even an online-only version of the Web IDE that does two-way communications: http://espruin

As someone who's now shipped 2 hardware KickStarters on time (both of which were bigger than KoalaSafe), I find it a frustrating when people post up 'hardware KickStarters never ship'. It's just not true. It's defin

Just to add: Overall open source has been great in my case. It's just that it's very easy for someone to make a comment on the internet - it doesn't mean they're particularly bothered about it or are prepared to do anyt

I actually had a lot of success with Open Sourcing. After a year of making virtually nothing out of selling Espruino as software (while being bombarded with sometimes abusive comments about the fact it wasn't Open), I decided to put it

As one of buro9's users, I have to say I was very happy to hear that the software was going to be Open Sourced, however I was dreading having to migrate it all to my server. In the end I'm much happier that buro9 found a way to

Yes, it'd be really handy... Having said that, to be truly useful you'd need to be able to access whatever it was from some API that was common across platforms. Sadly I think it's very unlikely that any simple communications

Thanks! I'd seen your post when I googled to see if it could be done. It's just nice not to have to wire up so many components, or to need a battery!

There is a demonstration there of full loopback, without the 1 sec delay. The delay is purely so you can send a command using a totally normal audio API that only uses the sound card when needed. I could probably get away with 1 stop bit...
