After a 3h wait at the Barbican, I’ve finally made it to the rain room. It’s a very strange experience walking towards steel rods of rain that get no closer to you.
Little spherical globs of evil.
Canaries? What canaries?
A week in the canary islands and I’ve not seen a single canary. Have I been lied to?

Hellschreiber
What do you get when you mix a cheap MSP430 development board with a simple oscillator circuit and blend in a handful of code from various sources? Hellschreiber– a radio transmission mode invented in the 1920s.
The screenshot above shows the signal as transmitted across my bench – a distance of about 50cm. The text being transmitted is “G7UVW / QTH / JO01BN / QRPP / Hellschreiber”. The slanting of the text is due to the drift in frequency between the transmitter and receiving radio and also timing errors in the transmitting code.
