archer = two thousand pounds (£2,000), late 20th century, from the Jeffrey Archer court case in which he was alleged to have bribed call-girl Monica Coughlan with this amount. ayrton senna/ayrton = tenner (ten pounds, £10) – cockney rhyming slang created in the 1980s or early 90s, from the name of the peerless Brazilian world champion Formula…
This brief note discusses methods of moisture content measurement commonly found in the lumber and furniture industries.
A minimal table to compare the Espressif’s MCU families (ESP8266/ESP32/ESP32-S2/ESP32-S3/ESP32-C3/ESP32-C6).

Resistors are available in a large number of different package styles and sizes. The most commonly used resistors are rectangular surface mount (SMD) resistors, but the older axial resistor is still used extensively in through-hole designs. See the dimensions of SMD, axial, and MELF packages and also some recommended land patterns for SMD components for soldering to PCBs.
The DFPlayer is a great little MP3 player module at a fantastic price, but there’s a really odd design choice; it has a high quiescent current of about 25mA.
