Goodbye Standby
Energy saving has been a hot topic for some forty years now. In the early years the focus of public, political and specialist attention was on the large-scale users of energy, but now attention is also turning to the much more numerous smaller-scale users, on the principle that ‘many a mickle makes a muckle’.

Gerber file
CAM/CAD data for the PCB referred to in this article is available as a Gerber file. Elektor GREEN and GOLD members can exclusively download these files for free as part of their membership. Gerber files allow a PCB to be produced on an appropriate device available locally, or through an online PCB manufacturing service.
Elektor recommends the Elektor PCB Service service from its business partner Eurocircuits or AISLER as the best services for its own prototypes and volume production.
TIP: your first PCB at AISLER is free up to €30 with using the coupon code ELCCBB at checkout.
