Sold/Expired datiLED Battery Drainers

[datiLED]

For sale are a variety of battery drainers that I have built, ranging from prototypes to my latest lantern build. There is even a DIY option for the adventurous type. It has been a long time since I have offered these, because of the time it takes to catalog and put up a listing. The blue tape that is visible in some of the pictures is for my organization, and corresponds to the item numbers in this thread. It can be easily removed.

Price listed does not include shipping, which is $3.50 for USPS First Class shipping within the United States. If purchasing 3 or more items, shipping is free.

Items are shown from front row, left to right.

Missed out on the lanterns! I would love to put one in the baby room with all the used akaline cells from work!
Looking forward to more when you make them!

The lanterns are pretty cool and the top of a chapstick tube sits on top of the regualr ones these perfectly and makes a great diffuser.

What's the voltage range on the other models where you don't specify?

In for 19, at least.

All of the VoltVamp and two transistor boost circuits are 1.5V, to make the most of partially depleted alkaline batteries.

The 3V battery drainers can use CR123 or 1.5V cells.
