    Got A New Flashlight...

    The full body of this small light does gets hot, quick, on turbo, as do all the powerful ones, on turbo. The big ones just take a bit longer. Turbo is obnoxious, constricts pupils, kills night vision. But power is good, grunt grunt. Stepless ramping down to desired/needed level..has memory...

    Got A New Flashlight...

    This light a while back was priced @ $13.50 with a additional 50% off coupon, and I could not resist: https://www.amazon.com/dp/B09MLYDHV6/ref=cm_sw_r_apan_i_54SR0DVBCFXVW93D7JC2?_encoding=UTF8&psc=1 I linked this to a friend, whose order arrived before mine did. He was raving about it, and had...

    Rear End nightmare

    Back in early '08 I heard noise I didn't like from the rear, opened the 8 3/8 chrysler diff cover to find some heavily pitted spider gears, a caked magnet, and pitted axleshafts where they ride on the outer bearings. Got a few quotes from people who recommended I just get a junkyard axle. All...

    Dot 1717 Cooper AT3

    Southern, but coastal, meaning cooler, and more overcast days. I thought it strange all 4 tires show exact same issue in exact same place. And had i not been doing a rotation and brake tune, id be unaware of this visual deterioration. The sides facing out look fine

    Cracked samsung a11 screen.

    Think I spent 170$ for the phone some 14 months ago with the 2 day shipping which took 6. I would still be using my 2014 era S4 mini if my network did not phase it out. I have other 'wifi' phones compatible with my network(ting), but they were trac fone subsidized and attempting to get one...

    Cracked samsung a11 screen.

    Dropped from 3 feet or so onto cork flooring Landed nearly flat on face in protective cover. Shattered half of screen. Still works fine, but can feel sharp edges. Watched 2 different repair videos. Not sure I could do it... Devote the time, and try to develop the new skills. The heating of...

    plug-in seat heater?

    The bimetal switches they use to limit max temperature are too inaccurate. Some are placed directly on a heating wire. Other brands have higher temp ones off to the sides. Their wattage/ heating potential is directly related to voltage reaching the pad itself. Some have voltage dropping diode...

    I could use some advice about a 12VDC to 120 VAC inverter project:

    When hot, my engine, in drive, stopped, foot on the brake, idles at 525 rpm and the one 50/120 alternator can make its 50 amp rating. The other alternator with same 50/120 rating, struggles to make 40. Both K type thermocouples on each alternator are climbing rapidly the whole time I am sitting...

    I could use some advice about a 12VDC to 120 VAC inverter project:

    GoPower Samlex are 2 pure sine inverters on my wishlist, in that order. A parked idling alternator at 50%+ of output, gets much hotter, much faster, than when vehicle is moving with more.engine rpm spinning alternator fans faster with underhood airflow. Also voltage regulator itself gets hot...

    NorthStar AGM battery charging and sulfation woes with Optima® Digital 1200 Battery Charger.

    I would / will eventually switch to Lifepo4, as I intentionally deep cycle my Lead acid batteries, often. Lead Acid batteries can only be recharged quickly to ~80% state of charge, the last 20% means many many hours held at absorption voltage, before reaching true 100% charged. Achieving True...

    Songs with great saxophone

    Good thread, Lots of 'new to me' stuff to explore, and lots of stuff once appreciated but forgotten about. The eyes of the world will have me revisiting some old cassettes throughout the day. A lot of my musically inclined friends were once like: "Fela who?" and now they link me some of his...

    Prepping surface rust for paint

    Get some good gloves and some red scotchbrite. Wet the scotchbrite with Ospho and goto town, and use various implements to get into corners better than your gloved fingers.. When the rust turns black, you can chisel it off revealing brown rust below, and Ospho scrub some more. Can do this to...

    More and larger cooling fans

    Nah, I.m irritated with myself, as even with all the clues you provided as to your limited intellect, I thought it was possible to help you become better informed on a subject I am very experienced with. I'll waste a bit more time and then cut my losses and wish you good luck. You are...

    More and larger cooling fans

    I never did, nor would recommend using a small server fan in front of, or behind an automotive radiator. My applications for these fans falls strictly into 'other', and I almost always use the largest diameter fan I can squeeze into the application, and speed control via voltage from minimum...

    More and larger cooling fans

    Ok 'computer' fan, was a poor choice of words, as noise is a factor with most every computer. But good, I am glad you are irritated. Fester in it ! :0 This 12v 4.75"/120mm 'server' fan is rated at 254 CFM and has an impressive static pressure rating too...

    More and larger cooling fans

    I've done a bunch of experimenting with powerful computer fans when there is a restriction like a radiator either in front of or behind the fan blades, moving the fan orientation when at speed to push against or pull from a restriction, like a radiator, or Ac condenser. Almost every fan is not...

    Back Pain - What do you do?

    While the causes of back pain are vast and varied, and what works for one might not for another, I think we can all agree that a strong core is a desirable thing. I've been working my abdominal muscles regularly for a year and a half, and my incidences of back pain are about 1/10th as frequent...

    NorthStar AGM battery charging and sulfation woes with Optima® Digital 1200 Battery Charger.

    I've been trying to establish a few points regarding your Northstar batteries. 1: The smart charger deciding to never read above 75%, might mean absolutely nothing. If it stalls at 75%, what is the amperage it is accepting at the voltage the charger is holding the battery at? This is highly...
