Blucave Flashcell - Supercap Powered Screwdriver

[rippledabs]

Just came across this on amazon for $23. I am very intrigued with the supercap power source. Suppose to "charge in 60 seconds with up to 100,000 cycles".

Anyone got one? How many screw can it sink before dying?

I know it smells of hookie consumer grade marketing, but I'm in the market for a little screwdriver to place inside the kitchen drawer for misc house stuff.

eh. Looks like a waste of time to me. The battery is useless if it doesn't have the torque to do anything.

If you already have M12 stuff, a used 1/4 impact or drill is $40 all day long on ebay.

I like the snap on 7.2vs

Huh... I've never seen that before. I just bought one to take apart and see what's going on inside. Figure it's worth a video at least. Might be handy up in my lab for electronics teardowns anyhow. I'll get a set of better bits to store with it.

For 23 dollars I can't image a decent sized supercap capacity being in that driver, but it sounds pretty interesting.

Yay! Let us know how it goes!

The M12 impact and the dewalt would work good, but it's too much tool for the job of taking off little screws around the house. Besides, I have both the M18 surge and M18 fuel that's pretty close in size to the M12 and that dewalt driver. I just want a cute little one now.

Bought my wife one of these...

It's not bad.

Just got home from work and tore into my Bluecell Cavedriver whatever thing. First impression is better than I expected. Will report back after I've used it a bit and run some tests but, it seems worthy of 20$ at present.

Also I did not realize that it rotated to be a straight driver as well similar to that Dewalt above. We use those at work for ECM connectors. The dumb thing is though, since the head is now 180 degrees from the handle, the controls are backwards!

Nice, I just bought one. When it arrive, I'll take it apart and hook it up to a column counter to see how much energy is stored in those caps.

I took mine apart quick just to poke around. I'm still planning to do a full teardown with some analysis but the heart of it is a pair of 2.3V 300F Vinatech HyCap Supercapacitors in series. Not a whole lot going on in there. It pretty much looks like it just dumps the supercaps right onto the motor through the trigger micro switch (can't tell brand, logo looks like a fancy JL or possibly vancy V) and then a direction switch which swaps the polarity. The body of it is ABS with rubber overmolding. The motor is a 3.6V Leshi DC motor. Since it's 3.6V it's actually being overdriven a little bit technically off those caps. It goes through a planetary reduction gear to the final drive for the bit. I ran the motor removed from the geartrain and that sucker flys!

So far, I like the construction of it. It's freaking simple, but well done and solid. I've already used it a few times taking other things apart and it seems perfect for taking apart electronics. Won't strip a screw but will speed up removing 20 case screws. The bits that come with it are pretty fat though, so I'm going to get a set of Wiha bits that are a lot skinnier and longer for getting down into holes.
