266 IEEE-COPA 2025 fringe -Title: «Can gears that engage only so good make the machine run?» Tricky MEMS mic sampling etc.

263 An encounter with AI-powered Cursor text editor and XC – an a polite apology from the claude-3.5-sonnet AI engine

261 Beep-BRRR using smart home to extend its functionality– and more some about some Plejd products

255 My missing smart home connection – and some about some Plejd products

253 My audio automatic gain control sw driver (AGC) notes – Is a little about the Beep-BRR2 in general, and how I implemented AGC on the mic input, in order to try to «hear» better through a closed door

243 My MEMS microphones notes etc. – Is about how to find a proper microphone when moving from Beep-BRRR-proto to Beep-BRR2

​Also 219 My Beep-BRRR notes movies – The unit is able to “hear” a recorded sound (a “beep”) and trigger an output. This is connected via an audio cable to a clock and alarm unit, consisting of that clock with sound and light plus a separate bed shaker (which “BRRR”s)

219 My Beep-BRRR notes – Photo: the unit has a small display and four buttons

151 My single-board boards and why notes – Photo: my aquarium controller (2017) has run flawlessly since then, with an older XMOS processor
