I urge everybody to look out for a stereo microscope. Doesn’t have to be overly fancy, a simple one will suffice. Since I got mine - mostly for working on watches - it has come in handy many times. Just make sure it’s a real stereoscopic one.
Check out the gigantic soldering tip…
Bread and other carbohydrate staples may be doing more than just filling plates—they could be quietly reshaping metabolism. In a surprising twist, researchers found that mice strongly preferred carbs like bread, rice, and wheat, abandoning their regular diet entirely. Even without eating more calories, they gained weight and body fat, not because they overate, but because their bodies burned less energy.
#Anecdotique ? Sur ces vingt dernières années, les rendements des cinq cultures majeures (maïs, blé, riz, orge, soja) ont diminué de 5%.

T-Display-P4 smartphone-like devkit features ESP32-P4 MCU, ESP32-C6 wireless SoC, and SX1262/LR2021 LoRa transceiver
LILYGO T-Display-P4 is a feature-rich ESP32-P4 + ESP32-C6 devkit, but with a smartphone-like design and support for GPS, Ethernet, and LoRaWAN through SX1262 or LR2021 LoRa transceiver, besides the usual WiFi 6, Bluetooth 5.x, and 802.15.4 wireless connectivity. The T-Display-P4 is offered with either a 4.05-inch IPS display and a 2MP front-facing camera or a 4.1-inch AMOLED with a 2MP rear camera. The devkit is equipped with 32MB PSRAM and 16MB NOR flash for the ESP32-P4, a microSD card slot, a built-in microphone and speaker, a 3.5mm audio jack, a few USB ports, and a 9-axis motion sensor, as well as a GPIO port and two Qwiic connectors for expansion. T-Display-P4 specifications: MCU - ESP32-P4 CPU Dual-core RISC-V microcontroller @ 360 MHz with AI instructions extension and single-precision FPU Single-RISC-V LP (Low-power) MCU core @ up to 40 MHz GPU – 2D Pixel Processing Accelerator (PPA) VPU – H.264 and
Finally found a MOSFET with a small footprint and a low price that seems to be able to easily handle PWM for 12V/6W dimmable LED spots when driven by only 3.3V logic level: AOD424.
I use NRF52840 dev boards, as they have a minuscule power consumption of less than 15mA at 3.3V even with Bluetooth on and discoverable. Sure, not much of a difference when the lights are on; but when the lights are off, and you throw 20 of those onto your offgrid net, it suddenly matters!
