UPFRONT!

I created a Discord channel for my Thermal vision builds but will add a #meshtastic channel there as well in case you have questions or problems. Please remain to the meshtastic channel for all sort of questions as all the other channels are ONLY for my thermal builds!

A word of warning!

It looks like there are different types (at least 2) of dynamo flashlights with different internals (check comments) This of course sucks now! Even if you use my link I provided it seems like it is no guarantee to get the correct one. The PCB board as well the gears and Pins are different causing clearance issues making the gears rub against the case wall.

The LWC “Solamo” is a self sufficient Meshtastic Heltec T114 node that utilizes a solar panel as well a hand crank Dynamo/ generator in case of a total blackout. Featuring, a notification Buzzer, notification LED, canned messages, GPS and an external connector for I2C devices or sensors (like a card KB Keyboard) making this thing a totally off the grid Meshtastic node.

Even if you run the battery down completely and there is no sun you can still unfold that little crank and get to work to charge that battery.

Solar panel does deliver up to 5,5 volts @80mA, the Hand crank can produce between 50-70mA.
