I continue to subconsciously underestimate the strength of PLA and increase the % infill. Just stood on a printed case cover and it held up all 83kg😀
The battery compartment snapped into place.
The temperature sensor chip itself is just plugged into the socket because it is not meant to be a room thermometer - there will be a long cable to the outside.
I am happy with it, I used all the old parts and got a good grip on the alignment of the 3D printer table:)
On the fourth try, it was acceptable. I mostly raised the temperature of the table and the nozzle.
It would have been even prettier if I hadn't printed all the parts at once - multiple transitions from one to another with a stop in the flow of plastic clearly does not improve the quality:)
At this point we consider the project complete and return to #fpga :)
This is a nerve whim: having stumbled across attiny13 and ds18b20 in a drawer and having a freshly purchased 3d printer Aquila I wanted to build an outdoor temperature thermometer. The sensor is on a wire outside the window, the box itself is inside.
A toy, in short.😀
On the second day the device went out. It was a surprise - with 1000mAh batteries, falling asleep and everything else, it should have lasted at least a week😕
And only here I read about crystallization in NiCd batteries and the critical discharge to 0.9V before every charging, as well as the reviving to 0.4V and breaking the crystals by pulses of 100V.
In short I need a smart charger to replace this thing, which apparently was slowly killing battery capacity.
And while I haven't found the thing with 0.4V discharge, it looks like I'll have to make such a device myself.
