ESP32-S3 mini prototype board for small IOT projects
Winter Sep 21,2025
I designed a compact PCB for the ESP32-S3 Mini that mounts directly beneath the main board. It provides access to essential GPIOs and power (3.3V/5V), making it ideal for connecting a few sensors or buttons without the need for an extra veroboard / stripboard. This saves space and simplifies small projects where only minimal expansion is required.If you have just a few switches, buttons, I2C sensor stuff this will greatly simplify your small project.

LoRaTube: Long-Life LoRa Repeater in a PVC Tube (No Lithium, No Solar)
Sep 19,2025
That’s why a repeater is necessary: to fully exploit the available link budget and reach long distances, the transmitter’s location must be carefully chosen. By placing the repeater at a high point — a hill, tower, or treetop with a clear line of sight — a single module can cover several tens of kilometers without exceeding the legally allowed transmission power. This strategy is at the heart of the LoRaTube concept: keeping a compliant, very low-cost, discreet, and autonomous transmitter (...

ESPCistern: ESP32-C3 WiFi cistern monitor using MS5837 depth and BME280 air reference
Quispe Sep 19,2025
Battery powered Wi-Fi cistern level monitor using an ESP32-C3, one submerged MS5837 for water pressure and one external BME280 for atmospheric reference. The MS5837 has a fixed I²C address of 0x76, and the BME280 is set to 0x77 by tying SDO to 3V3, so there is no address conflict. The electronics stay dry on the top side of a pass-through PCB and the MS5837 on the bottom faces the water. The board is bonded through a single hole so the module remains outside and easy to service. USB-C is availab...
