The designs on this site are generally open source so you can recreate them yourself or modify them if you wish.
For those that want to purchase kits or printed circuit boards there are a number of options.
My kits and PCBs are available from Small Computers Direct, along with some of the components used in the kits. Purchases are made in GBP. This shop does not collect EU VAT, but it does handle US tariffs.
Many of my designs are also available through Tindie and Lectronz, which are market places for makers.
Tindie: Purchases are made in USD. Tindie do not offer country specific pricing or tax calculations. Prices shown here have been increased to include US tariffs. As a result I only accept orders from Tindie for shipment to the US.
Lectronz: Purchases are made in either USD or Euros. Lectronz collect EU sales tax (VAT) up to 150 Euros, so most EU customers will not have issues with customs. This store also handles US tariffs.
Some of my PCBs are available from pcb4diy. This is a website hosted in Germany and the PCBs are shipped from Germany. They also list PCBs on eBay.
