Hi David,
Sorry, it wasn't my intention to force you into making PCB's for everyone!!
Although re-reading my post above it does rather look like it was!
I have been involved in small scale kitchen PCB production in the past (Ferric Chloride- very messy!) so I know how much effort has to go into it. Your suggested price is very reasonable considering the materials as well.
If you do make some, I would love to have two if I may? With stations disappearing from MW, I suspect devices like the Minimod will be even more in demand than previously.
Thank you for the detailed post and for sharing your artwork.
Many thanks
Nick
