DIY Dust Cyclone

 This is my home built cyclone dust collector made from 2 Home Depot buckets and some 3D printed parts.

There are two inlet ports, one on each side.

The unused port is blocked using a plastic plug with a high-tech masking tape gasket.

Learning the Shapeoko

I'm gradually getting to know the Shapeoko CNC machne. It is great at carving but can make a big mess in short order if you don't know what you're doing!

Weather Instrument with Remote Sensor

 This one takes readings from a remote sensor in the back yard. It was built for a friend who has a pool, so naturally it has a pool temperature sensor as well!

The sensor has a thermistor which dips into the pool. The sensor transmits using LoRa RF technology at 915MHz. It runs off a battery which should last about 20 years.

On the back there are buttons to switch the temperature readings from Celsius to Fahrenheit, and a little cage for the indoor sensor.

Inside, the analog gauges are run from miniature stepper motors. The main processor is an ESP32. A 240x320 TFT LCD hosts the digital readings.

The LoRa radio receiver uses an RFM95 module and an ATmega328 processor.
