608 Bearing Balanced Wind Vane Rotor
A 175 mm wind vane rotor with a 65 mm tall swept tail fin. It turns on a 608 bearing (8 x 22 x 7 mm) pressed into a hub that is closed on top, so it sits on an 8 mm rod mast and pairs with an anemometer for a DIY weather station. There is a 19 mm ballast well under the arrowhead. Fill it with about 12 g of steel shot until the vane balances level on its bearing, so it points into the wind instead of sagging toward the tail.
Tipping-Bucket Rain Gauge Seesaw
This is the seesaw bucket for a DIY ESP32 or ESPHome rain gauge. It measures 70 x 34 x 25 mm and has two 33 x 26 mm compartments split by a centre divider. It pivots on a 3 mm steel pin through a 3.4 mm bore set low in the base, and a pocket on one side (8.5 mm across, 2.5 mm deep) takes a glued-in disc magnet up to 8 mm, so each tip triggers a reed switch mounted next to the bucket.
608 Bearing Anemometer Cup Rotor
A three-cup anemometer rotor that spins on two press-fit 608 skate bearings (22.05 mm through bore, stacked 14 mm apart) riding on an 8 mm mast, with a 126 mm swept diameter and 30 mm deep scoops. One arm carries a blind 6 x 3 mm disc-magnet pocket over a bridged roof so a hall or reed sensor below counts one pulse per revolution for a DIY weather station.
Louvered Outdoor Sensor Radiation Shield
A Stevenson-screen style radiation shield for outdoor temperature/humidity sensors (BME280, DHT22/AM2302, SHT31 breakouts): five 50° louver rings around a 42 mm ventilated chamber, 64 mm across and 54 mm tall, with a central 26 mm strap blade and four 5 x 4 mm zip-tie slots so any small PCB mounts without guessing a bolt pattern. The 36 mm mounting spine below the shield carries two 4.5 mm M4 clearance holes on 18 mm centres for a post, fence or wall, and the whole part prints cap-down with no supports — total height 92 mm.
