surveillance != safety.

I realised I need to build my stuff more in the open although I hate social media. So here it is:

currently working on OpenCartoCam

an open source 360° camera with onboard object detection for mapping an area. I am very happy to be supported by nlnet for this work.

working on a solar powered meshtastic node
50 mm x 50 mm

main components:

- HT-CT62 ESP32 / SX-1262
- NEH7100 energy harvesting IC
- battery fuel gauge I somehow need to integrate into the meshtastic installation

this is revision 1

Passive NFC thermometer, 3 ways:

- regular keychain form factor

- pocket knife, integrated into front scale

- 1 € coin as a personal challenge

All measuring at 0.1 °C accuracy while siphoning power from the NFC reader.

@fishPointer Nfc thermometer with power siphoning ;)

.@unsurv's ATtiny1626-based keychain thermometer tells you the temperature on the go, by harnessing energy from an NFC field. https://t.co/NBeWgu1ljp

After some days in bed to recover from #38c3
sickness.

Produced 12 new thermometers today.

Saved two boards from the debug pile and found a new possible error with the PCB. The new revision already has precautions against it. But some of my available boards are affected.

Better to find out now!

New unsurv offline boards should arrive this week!

[unsurv @unsurv]

Fought with an A4988 stepper driver the last two days and sent 12 NFC thermometers on their way thanks to a @hackaday blogpost :)

Aisler having a problem with my KiCad import for a new form factor for the thermometer today. Not sure whats wrong.

[unsurv @unsurv]

transferred the NFC thermometer design to a 1 € coin format today. Space is a little tighter but looks good

Trying out my new pixelpump from @robin7331 building my passive NFC thermometer. Works very nice until the OpenPnP is ready :)
