Andre Maia Chagas and his team, comprised of LL Prieto Godino, A Arrenberg and T Baden, have developed a Raspberry Pi-controlled microscope called FlyPi and entered it into the Hackaday Prize competition. Here’s what Andre has to say about the project:
Our plan with this project is to develop a complete opensource and cheap device for scientific experiments (data collection and analysis) and diagnostics (if they are “microscopy based”).
So far we were able to perform some proof of principle experiments in life sciences (Fluorescence and calcium imaging, opto and thermo genetics essays) and to perform diagnostics of the following parasites: Loa loa, Brugia Malayi, Wuchereria bankrofti, Schistosoma eggs, Mansonella perstans
It’s a fantastic and, above all else, useful project that combines that Pi with a camera module, an Arduino, 3D printed parts and various other bits and pieces. You can read more and see pictures and video here and also here.
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 it’s been written up in such a user-friendly way, as it has been over at Circuit Basics. In this tutorial, which features lots of screenshots, Scott Campbell has described how to connect your Zero, change a couple of config files and then set-up the necessary network connection.

Suffolk Libraries are holding a beginners’ Raspberry Jam over two sessions on Wednesday 3rd August. The sessions, which cost £1.50 per person, are being held in the Ipswich Enterprise + Innovation Hub at Ipswich County Library; the time slots are as follows:
- 10:00 – 11:20
- 11:40 – 13:00
Spaces are limited to 30 per session and children under 12 must be accompanied by an adult. To book, contact the library directly by telephone on 01473 263 810.
The folks over at Synchro.io have come up with a lovely robotic bartender solution using a Raspberry Pi. Called Drinkro, the system makes drinks out of vodka and several mixers using DC peristaltic liquid pumps connected to the Pi. There’s even a mobile app to allow you to order drinks! It’s very slow at the moment, as you can see from the video below, but you can read more about it on their blog.
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. The pins surround a mini breadboard and they are all protected by a resistor and a diode, making it much safer to prototype with. If you’re in need of unprotected GPIO pins, however, the pins are also broken out again to an unpopulated header. It’s a great, very positive review and you can read it here.
You can pre-order a RasPiO ProHAT from the RasPiO website.
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 battery. The system streams to their IoT service. You can read the full tutorial here. If you’re in the States, you’ll probably be looking to go to Adafruit for some of the bits. If you’re in the UK, Makersify is probably your best bet for everything except the LIPO.
