Summary

  • A user on the DIYPerks forum has showcased their new plywood desk which has an interesting feature, no wires.
  • The desk uses an evaluation kit from Etherdyne Technologies, Inc, which consists of a 100W RF power supply and a power antenna that loops around the desktop.
  • The power antenna works in a similar way to inductive charging in modern smartphones, but at a higher frequency and larger scale.
  • The user embedded the PCB coil receivers built into several devices, including a lamp, heated cup, microphone, speakers, a mouse, and a keyboard.
  • Additionally, the user customised a base to run their monitor, which demonstrates the large power pulling capacity of these PCB coils.
  • Some concerns were raised about the hit to efficiency vs cabled everything and the power usage, with a 10W base draw.
