micro:bits on eBay

The first few micro:bits are now appearing on eBay and are fetching good money, around the £30 mark for both auctions & buy-it-now.

Economic theory says that the price will drop if the market is flooded so I’d expect prices to sort themselves out very quickly. There is also a limited pool of people to sell to – there can’t be that many tech types that couldn’t get hold of one to play with by other means or use some other microcontroller board.

None the less, still very frustrating.

More sensors in the works

Thanks to everyone that has given us feedback.

We are working on some additional sensors along with more code snippets. The ‘coming soon’ sensors include:

  • A more basic temperature sensor
  • Piezo buzzer
  • A small speaker in a box (with a basic amplifier), powered by the micro:bit
  • A transistor output that can then drive motors or relays – depending on what you drive depends on whether another power source is required
  • A small low-load motor for the transistor output
  • A dual-colour LED
  • A full colour RGB LED

All products will have code snippets added soon.

We’ve had some requests for ‘the missing manual’ – we don’t have the resources to refactor the BBC materials at present but it is in the back of our minds.

However, if any group of schools or local authority want to arrange a venue & attendees, we’d be more than happy to come and deliver some quickstart training on both micro:bit fundamentals as well as using our accessories in projects.

Pin 12 is official available

microbit device pinsPin 12 on the micro:bit was reserved for other uses but has now been released for general use.

This means it can definitely be used for a robot driver board to allow two motors to be controlled for forward & backward movement.

My robot, a ChickBot micro:bit prototype, had used pin 12 but it’s use was off-book. With this news I can plough on with making a driver board for a micro:bit to plug in to.

I’m hoping the evil genius R&D department can find a way of hacking a speed control out of the outputs we have available from within the block editor – fingers crossed!

Lead times for bulk orders

We’ve got a fair amount of stock in for the ChickBot crew apart from Water Sensors which we only have two left right now.

To meet these price points, we buy in bulk from China. Orders take between 15 and 20 days (on average) to reach us. If you have a need for a class set of a particular item, please bear in mind that we may be between shipments and it could be as long as a month before we can ship your order to you.
