2021 has been a challenging year for most of us in one way or another. Despite all of the events that have taken place in our personal lives and the world around us, there is always something to be thankful for. Some people may need to look harder than others, but with a bit of consideration we can all think of something. These are the things that we should dwell on. With that in mind, and Thanksgiving just around the corner, I would like to do a small giveaway of various battery drainers that I have built.
The rules are simple.
1. Share something that you are thankful for. It can be an event, a person or anything that brings you joy.
2. Post only once in the thread.
3. Open toU.S. residents only anyone with a U.S. mailing address. I apologize to our International friends, but the shipping is an issue for me.
4. The giveaway will end at 11:59pm on November 20, and seven (7) winners will be drawn at random using automated software. It will take time to organize and notify the winners, and additional time will be required for the selection process. Please be patient for this part!
5. The winners by order of selection will have the opportunity to select their battery drainer from those available or remaining. Obviously, the person chosen last has no say in the matter and will get the remaining light.
Now the fun stuff. From back row, left to right
10mm ZXLD381 (1.5V) battery drainer with 3400K high CRI LED. Perfect for draining AAA cells (or any other 1.5V battery). Will not stick to vertical surfaces like other drainers, but so tiny and cute.
Original 1.5V VoltVamp circuit with some PCB artwork that I was testing. 5400K high CRI LED and koi silk screen.
1.5V through hole battery drainer prototype with cool Nichia GS LED. A real performer and drains cells low. Plus, you get to see the circuit!
CLAIMED 1.5V original VoltVamp with 3400K high CRI LED. Magnets do not stack, but it is an over achiever.
CLAIMED 3V battery drainer with slow color change LED. Good brightness and color changing display while draining 1.5V or 3V cells that won't work in other lights.
CLAIMED 3V battery drainer with 3400K high CRI LED. Gets the last lumens out of the 1.5V or 3V cells that won't work in other lights.
CLAIMED Parallel 1.5V VoltVamp battery drainers with 5400K high CRI LEDs. Twice the light, while draining two batteries. Can be used with a single battery to drain it twice as fast. It seemed like a good idea at one time, but now that I type it out?
