Much of my time is spent designing, then 3D printing “JUNQUE”. That’s my favorite term for the over-production of plastic items.
It’s not junk that one would just throw away. It’s nice “stuff” but I make way more than I really need. I generally give it away or encourage my wife to gift her friends.
This makes room so I can generate more quality JUNQUE.
My recent nice Junque has been a series of small electrically powered LED (Light Emitting Diode) table lamps. They are powered by 5 volt USB charger and consume 1 watt of power.
All are dimmable to very low light levels. Suitable for mood lighting or night lights. Not great for reading or task lighting.
I started making some conventional style table lamps with white bulbs. I then discovered source for flat round (puck) LED light discs than produce all colors of light and are sequence programable. (Flash, Strobe, Rotate colors, etc.)
Operating cost of a one watt lamp is extremely low. I currently pay in my total electric powered home, an average cost of $ /KWH
Here is the math:
1 watt X 24 Hours = 24 Watt Hours (WH)
24 WH X 365 = 8,760 WH/year or 8.76 KWH energy used per year with continuous operation (24/7).
My current electrical cost is $0.175 per KWH
8.76 KWH X $0.175 = $1.54 (rounded up) electrical cost per year.
I assume running far less than full bright would reduce this cost significantly.
I have not actually measured the power consumed by these devices with a power meter. The cost is so low it doesn’t justify the purchase of a power meter just to confirm. The cost of operation is calculated, $0.0001757 per hour.
