New Example Project (and new Reward!)

Posted by Gordon Williams (Creator)

Andy asked if he could make a bluetooth phone-controlled Robot, so we thought we'd give it a go. We even managed to make it voice-controlled, without having to write any software for the phone!

There are more details here:

We've also just added a new reward - the Low Power Wireless Kit. It's got two Espruinos, and two of the amazing NRF24L01+ wireless transceivers. 

These use virtually no power when in standby and work from up to around 60m away, so you can leave one Espruino inside and have one battery-powered Espruino outside transmitting data back to you every minute! You could even buy another wireless module, connect that to a Raspberry Pi, and then control your two Espruino boards wirelessly from the internet!

      @Gordon - thanks for considering my suggestion and making it a reality. Having choices of both BT and NRF in the kit will be a definite plus. Appreciate it!

      Yes, I've been thinking of that - unless we design and make our own (which would be ideal) I'm not sure we'll be able to supply it in the kit at a sensible price though. I got an Adafruit CC3000 module today, but in the UK it costs about as much the whole Low Power Wireless Kit!

      On that subject, it'd be nice if one of the options came with the CC3000 chip, maybe an "Internet Ready Kit", or something like that

      Hi Craig - that sounds like I great idea! In the survey that gets sent around after the KickStarter finishes, I'll add an option for whether you want a mix of Bluetooth/NRF modules instead

      For the £99 wireless experimenter kit tier, would it be possible to swap out a couple of the Bluetooth modules for NRF24L01+ transceivers? Looking to be able to tinker with both wireless technologies.

      Nicolas: Check this out - it's pretty simple
      At the moment that functionality is only on the Raspberry Pi version, but we're planning on adding a driver for the CC3000 WiFi chip (used in the Spark Core/Tessel/etc) so the Espruino board you get should have that functionality by the time you get it!

      Andy: It should be pretty easy (but you'll have to butcher a few of the lego cables so that you can connect it up nicely). The motor driver chip would drive 2 motors (or 4 if you only want them to go one way) easily, but you could solder on two ULN2003 chips instead and get enough powered outputs for 14 lights/motors!

      Great thanks :D I think I may have to get a few of these. A good example would be how easy is it to work with lego technics?

      What would it take to connect an espruino board to the internet? Keep in mind I'm a complete noob when it comes to electronics, but I do have a good understanding of http.
