Made a "How much wax will I need?" calculator for candle making. Uses a formula that multiplies the water weight of a container by the specific gravity of the wax type. waxcalculator.netlify.app source: github.com/tkroo/howmuchwaxwillineed #svelte #candlemaking

A thermometer with high and low set temperature alarms. I'm using it for melting/pouring candle wax. Initially measured -4°C in an ice bath and ~96.25°C in boiling water. I used the "calibrate_linear" filter in esphome to correct readings. Kinda sorta mostly […] [Original post on fosstodon.org]

Prepping addressable string lights to adorn my friend's Christmas tree. There are 600 LEDs, powered by a Pixelblaze controller with an output expander that breaks them into three 200-pixel lengths for better power distribution. Gonna try to map their positions on the tree for cool 2D/3D patterns.

More #candles this time using a soy, coconut, apricot, and paraffin wax.

8 light green candles in glass jars on a wood floor.

8 glass jars on a kitchen counter with wicks and pieces of wood to hold the wicks in place, filled with 170° F liquid wax, which is dyed light green.

Minor upgrade. Added an 128G eMMC module to my #LePotato running #pihole on #armbian. armbian-config made it simple to transfer the installed OS from the sd-card to the emmc module. Had to fix a permission problem on one file to get pihole web ui working again. #librecomputer

Libre Computer Le Potato in a case with the top off.
