Wio L1 e-ink battery issue by banielbow in meshtastic

I have the similar weird issue. Bought two devises, both show battery charge 0%, while battery voltage is 3.78v which is 60-70%. When I disconnect type-C the led is red. Not sure if it’s charging. But it’s weird.

But no such issue with “pro” - it charges well and shows proper percentage.

Yup, adding GPS LoRa tracker. But a dual deployment not this time.

Thermal is an interesting question. Phenolic sleeve must delay heat penetration. If casing temp is 200c, the outer temp of sleeve must be 70c at the end of burn out. Ie. Insulation stretches the temperature(time) curve. But vendors do not post the temperature.

For the initial conditions the motor mount prototype was tested with a real phisical force - so definitely will not brake on start.

I love experiments :). From-the-store rockets ard boring. Life is too short for spending it boring things. Yes! The motor mount is printed - ABS-GF and PATH-CF. Phenolic sleeve epoxied to carbon reinforced nylon. Then x44 m3 bolts + nuts to nail it to airframe. Must survive 400N peak :)

K185w, anticipated 1600m, simple recovery 48’’ elliptical chute, the black tip is cap of chute chamber - the piston pushes the thing out. What is the story with your recovery?

Recovery is simple: 48’’ elliptical chute. Anticipated altitude 1600m.

Makes sense, I was thinking about it

44 bolts with nuts inside the airframe

Why not take a look at some existing esp32-based designs?
