This candle was a prototype for the similar looking candles I made for some of my friends as Christmas presents.
I plan to make more someday soon, if you have any empty Absolut bottles you would like to give me, please notify me.

I was fortunate enough to receive my Tiko for Christmas from batch #1. Starting on Christmas day I printed a bunch of owls, a benchy, and some other ornaments as well as the Tiko demo print.

Some Eee PC customizations via shell script

	*  Disable suspend to ram when AC adapter is plugged in and the lid is closed.

	*  If the lid is closed and the AC adapter is unplugged, then suspend to ram is run.</description>

Hardware

Using a ESP32 with QMC5883L compass module. TBD

Accuracy

Quite accurate, each interval (max to min to max) from the water meter appears to be 32.5ml, this was confirmed over the course of a few days and about 1.6 m³ of water (about 49 thousand intervals).</description>

        <description>Sump pump Monitor



My parents have a cistern and a sump pump which would be useful to have some sort of water level monitoring.

In the past, we would check the cistern level with a pressure gauge calibrated in inches of water. There was a rubber squeeze bulb which which would pressurize a plastic line which fed into the cistern, and the resulting level would be shown on the gauge.</description>
