Some individuals hate cables with a ardour; others are agnostic and like cabled peripherals to having to cease and cost their mouse. [Matt] from DIYPerks has the very best of each worlds with this wireless-powered, no-cable desk setup.
The key is embedded throughout the plywood desk: an analysis equipment from Etherdyne Applied sciences, Inc consisting of a 100 W RF energy provide and its related energy antenna looping across the desktop edge. The mechanism is just like the inductive charging usually seen on telephones these days, however at larger frequency and bigger scale, enabling energy to be transmitted a number of ft (a minimum of a meter) above the desktop.
The equipment from ETI contained a number of PCB-coil receivers, which [Matt] constructed into numerous units, together with a lamp, heated cup, microphone, audio system, his mouse, keyboard, and even a customized base to run his monitor, which actually reveals the ability these items can pull.
The microphone is a non-Bluetooth RF unit lovingly modified to studio high quality, a minimum of so far as we will inform on laptop computer audio system via YouTube’s compression. The audio system use a pair of Bluetooth modules to barter stereo sound whereas staying in sync. And earlier than you ask “what about sign for the monitor?”– now we have to tell you that was taken care of too, by way of a wi-fi HDMI dongle. Test it out within the video beneath.
In fact the elephant within the room right here is energy utilization — there’s a ten W base draw, and possibly a giant hit to effectivity vs cabled-everything– however we determine he will get partway to a move on that by utilizing a Frameworks mainboard as a substitute desktop {hardware}. Certainly, a full evaluation would possibly present that the transmission effectivity of this technique is not any worse than the ability to cost/discharge inefficiencies in a extra standard battery powered wi-fi setup.
Whereas no wires is fairly clear, we’re unsure this beats the totally-hidden-in-the-desk PC [Matt] constructed final yr by way of minimalist aesthetic. That Frameworks mainboard additionally probably lacks the ability of his triple-screen luggable, however this was nonetheless an entertaining construct.
