The new hotness in cheap radios this year has been the Quansheng UV-K5, a Chinese handheld transceiver with significant RF abilities and easy modding. The amateur radio community have seized upon it with glee and already reverse-engineered much of the firmware, but flashing the thing has always required a minor effort. Now thanks to the work of [whosmatt], it can be flashed with little more than a web browser and a serial cable.
This feat was made possible through the magic of WebSerial, a handy feature that allows web applications to talk to connected hardware. We’ve seen it in action a few times in the world of badges, and as browser support for it has improved it’s now available through browsers on all the major platforms.
The web app allows tweaking of the Quansheng settings and will, no doubt, be capable of uploading that when fully open-source firmware is available. It should be of great interest well beyond the world of Chinese radios, though, because we’re guessing there are a lot of projects that could benefit from such a ubiquitous interface tool.
If you’d like to know more, WebSerial is something we’ve looked at in the past.
