DIY force sensor for teaching Physics, three components - no soldering and all in a 3d printed case. @adafruit.com ESP32 Feather V2, Adafruit NAU7802 and a load cell. Case on printables (www.printables.com/model/147909... ) and code on Github github.com/RGill-1/Blue... .

A level physics demo - dropping a magnet through a copper tube. This time with a force sensor data logger so we can measure the extra downward force in the copper tube as the magnet falls within. DIY Bluetooth sensor in 3d printed case that streams the data to @phyphox.org app. #iteachphysics

Teaching energy levels for AQA A-level, chance to get out the DIY spectroscope and put it in front of different light sources (in this case a fluorescent bulb). Rasp pi, camera and diffraction grating. Annual shout out to Les Wright for his pyspectroscope (2) software that makes it possible.

Our data loggers well and truly past their use by date. Can't remember who it was that first drew my attention to these cheaper light gates. We bought a sample pair and successfully did the GCSE and A-level req practicals with them so they are looking like a viable replacement.. #iteachphysics

To anyone considering family train holiday in Europe, it works. Back from two weeks; LDN>Brussels>Munich >Verona>Turin->London. 6yo fave train, the Nightjet sleeper to Munich. Rest of us, the train over the Alps into Italy. Hat tip to @seatsixtyone.bsky.social for opening eyes to what is doable.1/

Away this weekend, chance for a different Parkrun. Really great marshals and super welcoming to this not v far travelled visitor. Trying to gauge fitness one month out from Chelt HM, so got permission from the 8 y.o to go solo. Just need 5k speed to translate to 21k slog somehow. #edurunners

The annual challenge of trying to get a booking at CERN for a trip with our YR12 Physics students. Tight window when we can go, and spots go so quickly! Desperate f5 ing of the website and a couple of late nights has netted a booking, now crossing fingers flight times line up..

On the train to the ASE conference in Nottingham. Will be at the school exhibit with the DIY sensors we build as part of a school project. 3d printed cases, off the shelf electronics and using @phyphox.org to visualise the data - inspired by @cleapss.bsky.social Arduino builds.

Follow up lesson to slicing/3d design was some physical computing. Cut 5m reel of assessable LEDs into strips of 8. Dupont -> edge connector and the students had a whale of a time reacquainting themselves with @microbit.org coding. The neopixel library meant all could come up with novel uses.

Favourite three from class of students using tinkercad to design bookmarks. Making good use of the multi colour printing available to them. Simple but effective

About to teach specific heat capacity at GCSE. Flicking through the sensor project albums reminded me how clean the 'method of mixtures' demo came out with a home brew double thermistor setup. Placed one thermistor in the brass block and the other in the water it is submerged in.

New to the platform - will mostly be posting about Physics teaching and tinkering with electronics / 3d printing to make DIY sensors to use in the classroom
