Badges Of 2022: EMF TiDAL


As we bit by bit return to a summer of obtaining together in fields for our festivals of hackery, it’s time to appear at an additional of this year’s crop of badges. The UK’s Electromagnetic Industry, or EMF, is ordinarily a two-yearly party, but its return this year arrives just after a 4 year absence because of to the pandemic. The EMF 2022 badge is a departure from preceding outings, absent is the handheld game console type component and in its put is a svelte USB-C stick with a nod to the to start with era of EMF badges in its wave shape.

Bodily the badge is fashioned of two PCBs that plug jointly with the LiPo battery sandwiched among them, the higher 1 carrying the display and battery whilst the lessen holds the ESP32-S3 MCU and the many peripherals. These include things like a QMA7981 accelerometer, a QMC7983 magnetometer, and maybe most intriguingly, an ATECC108A cryptographic accelerator. This previous ingredient presents it the probable to be a 2-component authentication key, which we think is likely a first for a badge.

In use, the TFT exhibit and joystick interface is usable, but difficult to read through for a Hackaday scribe whose eyes possibly are not as sharp as they employed to be. Programming is by way of MicroPython, applying an application structure via the very same on the internet hatchery method that will be common to owners of other European badges. There are currently rather a few applications, which we hope will help this badge have some longevity.

This is just the newest of a long line of EMF badges, of which the 2016 edition is in all probability our favorite.
