You've got a circuit design and no way to get it onto copper without a proper photo-lab. This fixes that in four steps at your kitchen table. Drop a sheet in the tray of any laser printer or photocopier – it's A4-sized, so no fuss. Print your track layout. Press it onto a cleaned copper-clad board with a regular clothes iron. Peel. Etch. The image transfers to the copper and won't wash away in Ammonium Persulphate or Ferric Chloride. Five sheets per pack, full instructions included. Add to cart and you're etching this weekend
