 * [Daniel] started work on [`bluetooth-hci`], an abstraction layer for HCI based Bluetooth Controllers, and is using it in his [`bluenrg`] crate for STMicro's BlueNRG RF modules
+* [cr1901] shared his [`AT2XT`] project, an adapter that allows use of low cost PS2 keyboards with older computers that expect (now very expensive) XT keyboards. The firmware for this project is based on `rtfm`, and runs on an `msp430` microcontroller. Check out the [short blurb] by [cr1901] summarizing the project
 * [hannobraun] released v0.3 of his [`lpc82x`] Chip Support Crate for NXP's LPC82x family of microcontrollers, as well as v0.1 of [`lpc82x-hal`]. Check out the [lpc82x-hal announcement] here!
 * [japaric] released v0.3.1 of [`heapless`], a crate for fixed capacity implementations of `HashMap` and `HashSet` that does not require the use of `std`, an allocator, and used `u32` hashes (instead of the default `u64`).
