Moto Z modular Android phone gets a Raspberry Pi HAT adapter
Motorola and Element 14 have launched a development kit for creating add-ons for the new Moto Z mobile phone. As well as this kit, they’ve also announced that there will be a Raspberry Pi HAT adapter board (pictured above). It…
Enviro pHAT reviewed and used with the Raspberry Pi and the Initial State dashboard
Jamie Bailey has written a great review of Pimoroni’s Enviro pHAT. He’s evaluated the sensors on-board and has then integrated them, using Python, with the Initial State dashboard. He’s used the temperature sensor and accelerometer to provide data and has…
Raspberry Pi home automation stops fumbling in the dark (more’s the pity!)
The bloggers over at WhiskeyTangoHotel have been investigating home automation solutions. They’ve come up with a Raspberry Pi-based solution which detects, via Bluetooth, the presence of a device (in this case an iPad) and switches on some LEDs to save…
Directly connect to and program your Raspberry Pi Zero over USB
For a while, it has been possible to communicate and program a Raspberry Pi Zero via it’s USB data port. I’ve covered this useful feature before, beginning with Andrew Mulholland’s original work but I feel it’s worth covering again, particularly when…
The MagPi reviews the RasPiO ProHAT for the Raspberry Pi
In the MagPi issue 47, Phil King wrote a review of the RasPiO ProHAT. This clever prototyping HAT breaks out all the GPIO pins in numerical (BCM) order to female headers as well as adding several power and ground ports.…
Mobile data and GPS enabled Raspberry Pi Zero
Rachel Gibbs, over at Initial State, has written a great tutorial which gets a Pi Zero online via a mobile data connection. She’s added a GPS module to the FONA board and then powered the lot using a small LIPO…
Controlling a toy crane from Scratch on a Raspberry Pi using the SenseHAT
Albert Hickey wanted a new project to take to Jams. He’d seen the micro:bit controlling a toy crane so he got hold of one at Home Bargains. He used the SenseHAT as a controller and, thanks to a handy tutorial from…
Create an attendance system using RFID and a Raspberry Pi
Over at Circuit Digest, Saddam has written a tutorial that helps you to create an attendance system based on RFID cards and a reader. The code is written in C and Saddam takes you through it all so you understand…
Calculate true North using a Raspberry Pi, a GPS and a compass
CodeGirl42 has written a very comprehensive tutorial that teaches you all about GPS and taking magnetic North bearings using a magnetometer. There’s a lot of maths involved, but she takes you through it and then creates a C++ script to carry…
