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):

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.
The recently released Power-over-Ethernet HAT from Raspberry Pi was designed to allow the Raspberry Pi to be powered by a single power-enabled Ethernet cable. Aimed mostly at the industrial market, this HAT uses the extra 4-pin header on the 3B+ to receive the power from the cable and includes a fan for cooling.
However, users of the HAT have quickly encountered problems and have reported them on the Raspberry Pi Forums. The problems have boiled down to under-powered USB ports when using the HAT. In an interview with The Register, Eben Upton of Raspberry Pi Trading has explained the cause of the problems and why they were not picked up during the (apparently limited) testing. RPT is now offering refunds through vendors for returned units, although suggestions for fixing the hardware issue have also been given (not for the faint of heart!)
Ivan Holland from CPC has been taking a look at the new PiTalk board from SB Components. The board, which was originally a successful Kickstarter campaign is a 3G-enabled mobile tele-communications solution for your Raspberry Pi. Plugged into the GPIO pins, and with a SIM card added with an appropriate data package, you can trigger actions on your Pi from another phone. Very nifty. With the use of an extended GPIO header, you can piggyback other GPIO boards and HATs and produce versatile projects. Aside from a few issues with the accompanying software, Ivan gives the product a thumbs-up. You can read the full review here.
