    Can I just use impact sockets?

    I've grown to like my Milwakee 1/2" deepwell impact socket set. I like the nice white numbers and useful case. I almost never use it for impact though. I use it whenever I need 1/2" drive sockets, just because the case is nice, and those white numbers make them nicer to use than my non-impact...

    Solar for intermittent high drain things

    I have an electric lawn mower. The charger draws several amps, but only runs for an hour to charge the battery, and that only once per week. If I put a solar panel on my shed, with a buffer battery like one of those LifePo batteries that have a built-in battery management system, the solar...

    Flexible conduit identification

    What kind of cable or conduit is this? I want to re-route the wiring. But I can't tell if it's "metallized cable (MC)" or "flexible metal conduit (FMC)". They are different and use different fittings I think.

    In search of good LED light bulbs

    I'm still looking for a qualified universal incandescent-replacement LED bulb Requirements: 2700k color temperature Good dimmability Rated for damp locations Rated for enclosed fixtures "75W replacement" or above (1200+ lumens) This is frustratingly hard to find, especially because...

    Automotive wire

    I'm installing a rear dashcam so I will be running about 12 feet of wire to my rear liftgate. I have to snake it through the rubber cable grommet, and under plastic moulding, so I don't want wire that's too fat or stiff. On the other hand I don't want it to overheat or melt. How do I decide...

    I have a cloth lunchbox and I want to take sheets of closed cell foam to make custom compartments inside. Is there a type of glue that works well?

    pinch weld jack adapters

    Like everyone else my cars have these pinch welds on the side, designed to be used with the scissor jack. Jacking them up from the same point with a floor jack would presumably be a good place to jack up the car, except the pinch weld being damaged. If you look at how the OEM scissor jacks...

    What lithium batteries have built in BMS?

    I found out my M12 batteries don't have any battery management or protection circuitry in them. That means if you use them with those 12v adapters, etc, you can discharge them too far and ruin them. I assume Milwaukee tools all have the proper circuitry in the tools. Do all 18V batteries that...

    Do you ALWAYS use jack stands? Help settle the argument.

    I swap between summer and winter wheels on multiple cars, multiple times per year. I was taught that jacks are only for jacking cars up, not supporting them. So I have a nice 3 ton floor jack that's reliable, but I always jack up the car, fiddle with getting jack stands positioned (and now I'm...

    How to choose a MOSFET

    I don't do EE stuff enough to remember how to pick out the right MOSFET for a particular job. Plus when I go to a site like digikey, I get 48,945 options and can't tell any difference between them. What I want to do is not fancy or high-speed. I could actually use an automotive relay, but I...

    Why do Scotchlocks have such a bad reputation?

    When doing car wiring or stereo installs, I've come to realize these things have a bad reputation, had people tell me "just don't use those scotchlock things whatever you do", even heard some people say anyone who uses them is automatically a "hack": Where does this idea come from? Do people...

    Can I run a furnace on a 120v generator?

    My small house has a small gas furnace. No fancy heat pump or multistage or anything. If there's a power outage in the winter I'd like to be able to hook up my furnace to my generator. It's a 2000W camping generator that's 120V only. I can buy a step up transformer for $100. But are furnaces...

    Jacking up a van by the hitch bar

    I'm never sure quite how to jack up my minivan. The owner's manual mostly shows you how to lift it at the pinch-welds using the spare-tire jack. That works, but then I still have to put jack-stands somewhere before I go underneath it, and there's not much guidance there. I really don't want to...

    How hard is it to change car tires yourself?

    I have changed thousands of bicycle tires, dozens of dirt bike tires, ATVs, and even semi-trucks tires. Semi-truck tires are surprisingly easy to change with the proper tire levers...probably easier than dirt bike tires. However I've never changed a car tire or even heard of anyone doing it...

    What socket sets have GOOD organizers / holders?

    I have basically a drawer full of loose and mismatched sockets that have accumulated over 25 years. I started looking for organizers to organize them all, but there's a small issue that you have to buy organizers that will fit the sockets...some sets have more or less sockets, plus even if I...

    Bags for organization

    I have a theory that the answer to my organization and storage problem involves greater use of bags vs. bins. I have a large need for storage: bike parts, nuts and bolts, special tools, electronics small-parts, spare car and household things that you might never need again...basically lots of...

    Cigarette burns in car interior

    I bought a used car that has several ugly, but small cigarette burns in the ceiling. I see that Permatex sells a fabric repair kit but I'm not sure how well it works...I may just go to Jo-Ann and get some grey iron-on fabric patches and put over them. Does anyone have a better repair idea?

    Making carpet floor mats

    I have a minivan I use for work and play and the carpet floor is going to get trashed. I don't know why they don't make everything with rubber floors you can hose out... I'm thinking about springing for weathertech, which work good for the front, but im my experience they just flop around in...
