I now have all of my prize for the Project14 Prototyping Techniques competition. Thank you element14 and tariq.ahmad
The components I chose were a selection of ferrite cores to experiment with, some transistors, a CAN controller and a couple of transceivers, a PLL chip (HC4046), and a couple of varicap diodes and dual-gate MOSFETs.
The final item, that I had to wait for, was the evaluation board in the centre. It's a breakout board for a Lattice ICE40UP5K. I had thought (wrongly) that the small ICE parts were simply programmable logic, but these UP (UltraPlus) parts also have block RAM and multipliers (16 bit), so they're quite capable little devices. I'll try and do something with it in the next week or two.
