Oh no! Free #lithiumPolymer batteries appearing in the wild in Canada too!

Haven't seen either of those in the UK not even under a different brand name. [pileofstuff] measured 4V on the battery from the rechargeable #eCigarette, 3.3V on the non-rechargeable #VapePen
Free batteries!

Look at how small the #lithiumPolymer battery is in relation to the size of the disposable #VapePen
1.48Wh (400mAh 3.7V)

Might be useful should I need to replace another battery in some wireless device, assuming I can recharge it - voltage is reading very low 1.2V

Hooked up the tiny lithium polymer battery to a TP4056 PCB to attempt recharge. Note the RProg resister has been replaced to limit current to 230mA. The terminals are so close together I've put masking tape over the positive terminal and clip to prevent accidental short

That pressure sensing capsule found in most disposable #vape pens can very easily be turned into a #touchSensitive switch that is capable of switching currents high enough to activate small relays and solenoids

Simply slice the top off, exposing the edges of the inner and outer conductive cylindrical walls. Bridging the two walls with something no more conductive than human skin is sufficient to trigger it

Touching only the inner wall with a wire seems to trigger it also. Implies that it is actually a capacitive touch sensor

14 months worth of salvaged vape pressure sensors - enough to make a capacitive touch keyboard?

@bornach I've never reused these, any simple hook up ideas for them?
