Super screwdriver: I have really enjoyed the HOTO AutoCare Air Duster and Vacuum, which despite the name has taken up residence in my kitchen. When I spill espresso grinds I use the vacuum to suck them up rather than attempt to clear them with a paper towel, which inevitably ends up spreading them around. I recently spilled some pepper on the countertop when refilling a shaker and once again, the vacuum made quick work of the job. This good experience led me to try the HOTO PixelDrive Cordless Screwdriver, which looks somewhat similar to the AutoCare Air Duster with its similar tube-like form factor. The HOTO mantra is "cool tools" and thePixelDrive is indeed cool, and the features are clever and genuinely useful.

The PixelDrive reduces effort while adding precision and convenience. To turn it on you simply twist the ring at the top, which also adjusts the torque applied to the bit. The display shows the chosen torque and an integrated ring light provides even illumination around the working area, helping you find the screw and stay centered. Two buttons are provided to control direction clockwise or counterclockwise. A light push of either button provides low speed, a firm push is high speed.

The screwdriver comes in a hard tube-like case that breaks down into three parts. Each part holds 10 different bits, for a total of 30. They are neatly arranged and held firmly into position, yet they pull out easily when you need them. The tool itself is very ruggedly built and feels like it is made to last.

This is a very well-conceived, well-designed and well-executed product. The HOTO PixelDrive lists for $79.99. Currently the code TOOL25 at hototools.com reduces the price 25% to $59.99. It also works for the $99.99 AutoCare Air Duster and Vacuum, reducing it to $75 either with or without the screwdriver. I tinker around the house a good bit and I've used cordless screwdrivers before, but this one is by far my favorite. The ring light, smooth operation, precise adjustment, comprehensive bit set and clever packaging make it a standout. Keeping the bits so well organized and always with the tool means you are more likely to use it, rather than reach for a common screwdriver.

Q. I have an ancient analog 14-inch Panasonic TV that still functions with a digital converter and an antenna. Recently the on/off switch failed so I need to plug and unplug it to turn it on and off. Since then I have looked for a replacement small TV, but can't find anything that small with a decent rating. I like the small size as I use it in the kitchen. I’d like to be able to use the new TV with an outdoor antenna, but I would really rather use my current TV if I can. Can you help?

A.If plugging and unplugging your TV turns it off and on, you can use a foot switch to do the same thing. It is much easier, and I have used these switches myself in similar situations when I need to unplug and plug in a device to reboot it or turn it off and on. Think of the foot switch as an extension cord with a sturdy button in the middle. Plug it in to the wall, and the TV into the outlet on the other end, and you can turn your TV off and on with a quick click from your foot. Many different models are available on Amazon. I bought the Coolneon brand for under $10 and it has worked well for many years now.
