Fireworks display using the Pimoroni Mote on the Raspberry Pi

This is a nice little project that I wrote the code for a couple of Sundays ago. It uses the Pimoroni Mote (full kit) to appear as fireworks and then uses Pygame to play the sound of fireworks as each Mote stick ‘explodes’ in a shower of sparkles! You can see the effect in the video below and see the code here. You can get hold of your own Mote from Pimoroni. This is all in aid of the Milton Keynes Raspberry Jam on 10th November which is a “Fireworks Special”!

 

Watch TV using the Raspberry Pi TV HAT and Plex with this great tutorial from The Pi Hut

Following yesterday’s news concerning the launch of the new Raspberry Pi TV HAT, the folks over at The Pi Hut have worked out how to stream to the Plex media server. It requires a plugin to be installed, but mostly it’s just a case of software configuration. You can read the tutorial over at The Pi Hut. You can get hold of the new HAT from The Pi Hut here.

Stream and watch television on your Raspberry Pi with the new TV HAT

Raspberry Pi has just announced the release of the new TV HAT. This Zero-sized board will enable you to receive a DVB (digital) television signal on your Pi and then view it or stream it to other devices on your network. It’s a nicely put-together board and is also the first to be in the new form factor, which re-defines the size and shape of HATs. There seems to be some confusion over whether it’s called a uHAT (micro-HAT) or just a HAT, though! You’ll need at least a Pi 2 to view programmes on the Pi (as it’s quite processor intensive) but a Zero will do for streaming.

The board retails for £20 and you’ll need an antenna and co-axial cable to connect it up.

You can buy the board over at The Pi Hut or from ModMyPi. There’s a great tutorial over at The Pi Hut on how to use the board and another from ModMyPi here.

Formula Pi 2018 – the finals of this Raspberry Pi-powered autonomous robot competition are tonight!

This year’s edition of the brilliant autonomous robot competition, Formula Pi from our friends over at Pi Borg, comes to a thrilling conclusion tonight (Wednesday, 10th October 2018) at 18.30 GMT. With an international field of roboteers, it’s sure to be exciting to watch. The following teams are in the ‘A’ Final (1st to 5th place):

  • lambda.p.racing
  • Chitty Chitty Pi Pi
  • Team Yoshi
  • Whacky Racer
  • Pi Hard

and the following teams are in the ‘B’ Final (6th to 10th place):

  • Pico HulkenBorg
  • Makerspace Randers
  • Team Limilo
  • lambda.q.racing
  • IQaudIO

Formula Pi is currently using the MonsterBorg robot from Pi Borg. Teams work on their code and then upload that code to Pi Borg to be installed on a standard robot. The races are entirely autonomous and the robots react to the changing ‘start lights’ to trigger them off on their runs. You can read more about the teams and the competition here.

You can view the live stream of the finals below, which is also here on YouTube:

New LoRa boards on Kickstarter aim to forge long-range communications links to your Raspberry Pi

Apologies for the dearth of posts recently – work’s been a bit… intense and Pi Wars preparations have taken their toll!

Pi Supply have launched a new Kickstarter campaign for several different types of add-on boards which use LoRa technology. So, what is LoRa?

LoRa is a revolutionary new method of sending small amounts of data over very long distances using long range radio and low power. It’s designed for the Internet of Things (IoT) so it’s perfect for communicating with sensors such as weather monitoring, air quality, smart homes etc.

You will need at least a Gateway and a Node to make the communications link work, and Pi Supply are offering both. The different Node boards work with the Raspberry Pi, micro:bit or Arduino and a Gateway HAT completes the equation as a receiver.

You can view the campaign video below and visit the Kickstarter campaign to pledge to get hold of the board(s).

Make a MIDI piano with the Raspberry Pi and a PiCap

The PiCap from Bare Conductive uses conductive ink to transfer touch impulses to the Raspberry Pi. They’ve written a lovely little tutorial on how to do it yourself and have put the code on GitHub. If you want to do it “properly”, you’ll need to follow their screen printing tutorial but you can get similar results by just painting the note ‘buttons’ on a piece of paper or card. The code is based on the FluidSynth synthesizer which uses sound fonts and is the basis for my own music tech project, the Music Box. Take a look at the tutorial here.
