Forty years minding SCADA panels in Biên Hòa before I hung it up. Turns out I can't stop, so I rebuild dial gauges and a level-bubble for the lens. Old hands, new glass.
Made
Unit conversions and kitchen math glanceable while both hands are busy
Round-up tipping math before the card machine times out
In their words
A gauge should tell you one thing, clearly.
