    DIY Lithium-ion battery charger

    Actually Lion chargers are tuned to the capacity of the battery they come with or are designed for, and it's not a good plan to use them for other capacities, unless you replace a few components to adjust the output for the type you want to charge.

  • Make Infrared Thermal Imaging Camera For Cheap ! Convert Any Camera Into Infrared Thermal Camera

    Yes you can remove the IR filter, as about 800 instructables will tell you, but NO that will not make it a thermal camera like the ones from Seek or FLIR.The removal of the filter just exposes near IR which is not the IR you get from heat emanation like the thermal cameras use, it's a completely different frequency range, and in fact those need lenses made from a special material since normal lenses would block the IR from that frequency range.However it's still a neat thing to see near-IR and it makes some interesting photos, it's just ludricous to compare the trick to themral cameras.
