Compiling for the Raspberry Pico on Arch Linux

 Posted on January 25, 2021  |  Barnaby Gray

The latest microcontroller on the market is the RP2040 in the form of the Raspberry Pico board - a compact SoC with many I/O pin configurations and great documentation – as we’ve come to expect from Raspberry! Getting compiling for this up and running is simple and I’ve made it even easier for Arch Linux with an AUR package to install the Pico SDK and necessary tools. For more generic instructions see the Raspberry docs. [Read More]

Mince pies

Tasty wholemeal alternative mince pies.

They are VERY delicate while they are warm especially if you have used butter.

Best eaten warm with a sprinkling of icing sugar on the top!

Running Tensorflow models on the Raspberry Pi

 Posted on November 25, 2020  |  Barnaby Gray

One of the features of our smart home is when the doorbell on our house is rung or a letter is posted, a snapshot is taken by a security camera pointed to our front door. The snapshot is then sent to a neural network to identify if it’s the post or not. If it is then house will announce this to us, which is handy to decide if it’s worth getting up from the sofa to pick up letters / answer the door. [Read More]

Zappi smart charging

 Posted on August 29, 2020  |  Barnaby Gray

With the emergence of dynamic ’time of use’ electricity tariffs like Octopus Agile - where the unit price you pay every half hour is tied to wholesale prices and varies throughout the day - there’s the opportunity to charge power hungry devices like electric cars to take advantage of really cheap (and greener!) electricity rates. Under 5p/kWh often, which equates to the under 1p/mile bargain prices. TLDR: The Zappi charger can be made smarter with a Sonoff smart switch to trigger charging on a programmable schedule.

Frying pan pizza

 Posted on July 29, 2020  |  Barnaby Gray

I originally got this recipe from Pizza pilgrims, a great restaurant chain in London. It’s the best results I’ve got at home for matching the sheer heat of a proper pizza oven to produce proper crispy thin based Italian pizzas. No thick crust here.

Take care with the hot frying pan - it’s really easy to get burnt!

Flammkuchen

 Posted on July 26, 2020  |  Barnaby Gray

Flammkuchen, flam-kuche, Flàmmeküeche lit. “flame cake” - many spellings, but all delicious - this is a German dish from the Baden/Alsace border region borrowed from the French (tarte flambée) borrowed from the Italians (pizza).

As a variation you can swap the creme for salsa and tomato to make something closer to pizza.

This makes two flammkuchen.
