Experimented something super strange with the capacitive touch of an ESP32. I enrolled the wire like an inductor and now I have an amplified touch detection that does not need even a touch! It can detect my hand from 1 or 2 cm! Super cool discovery @realwillreil, you will like this one!
Solar charger with I2C capabilities, designed to be deployed on our smart mini containers to reduce trucks in favor of bikes for your deliveries delipod.org
First time seeing an ESP32 in an actual commercial product! A Canadian product from @UnitedChargers Grizzle ev charger. Do you know other commercial products with an ESP32 module?
The solar charger module is taking shape: BQ25798, MOSFETs, Inductors, thick traces ... 100% pleasure!
First time doing a PCB for power electronics, now let's pour GND everywhere
BQ25798 from TI is not an easy chip to put on a PCB ! Wish me luck! The project is a 5A Solar charger with I2C monitoring and MPPT enabled!

1/16 Every half-bridge hides a tiny bell: copper plus FET capacitance. Switch too hard and it rings, hundreds of millions of times a second.
I simulated a real open-source motor controller at 48 V. Driver at full strength: its 80 V FET takes an 81 V hit. Turned down: clean. 🧵
This air-quality sensor just taught me who invented flash memory !

New card every day.
Text and illustration generated, then pushed to the ESP32.
@realwillreil the PnP ready, or do I keep placing these by hand?
I want to show you this simple 3D-printed lock mechanism I use to mount the IPS screen from @waveshare00 to my enclosure. No complex mechanism or screws needed. The CAD from my @adskFusion shows how it’s inserted and can rotate with enough friction to stay in place.
Maximizing all available CPU on this little Hetzner server is always a joy. Let’s parse all OSM maps with Valhalla!
We have a linear correlation between temperature and battery voltage for a CR2033; each degree gained is 0.01 volts. At this stage we will be capable of measuring temperature just by looking at the battery voltage.
It's very important to choose the right battery cell for the right environment, but crazy to see how cold kills a battery. No surprise that the majority of electric vehicles heat up the battery pack when it's cold outside.
Playing with Golioth these past days and it’s an absolute joy to set up OTA firmware upgrades and RPC calls, so I can call methods to set params or reboot an ESP32 in another country.
Super helpful to go from prototype to production-ready hardware.
