On Monday, June 9, more than 350 of the UK’s most successful and most promising technologists were invited to Buckingham Palace by the Queen and the Duke of York for Tech at the Palace.

Her Majesty Queen Elizabeth II was shown the Raspberry Pi High Altitude Balloon payload developed by David Akerman M6RPI (now M0RPI) which transmitted Slow Scan Digital Video (SSDV) signals on 434 MHz from the first “Pi in the Sky“. She also saw the TARDIS that was flown by David and Anthony Stirk M0UPU @AnthonyStirk
