    IR, oh what fun it is. I use the little handheld IR non-contact thermometers in my work. I now have an infrared camera, and learned a lot more. What range will they work? Forever. The catch is it takes an average of what it sees. A small apparent size will not be detected. If your target fills most of the Field Of View, you are measuring your target. Will it see thru glass? No, infrared reflects off of glass like a mirror. My camera can see someone standing behind me. My camera is sensitive and can even see warn foot prints on the floor. Will it give an accurate temperature reading of shinny surfaces? No, aluminum foil (flex duct and the like) reflects infrared the temperature of things around it. It will not see the temperature of air, but the things the air hits will give hints of the air temperature striking the objects. And have you heard of emissivity? Some things look like the temperature they are and others look like they are colder. On average they work well, but infrared is a very different color of light and somethings will surprise you.

    I too await a chance to stress test your system to OVER 16,000 items. Wait, how many items are in a one-day sale that will still fit inside you new diggs?
    I remember one company I worked for who’s first month sales was 3 times the forecast sales and we used our pickup trucks to pickup supplies until the distributors bought a new truck! Glad to hear it was a hit, even thought something hit the fan. signed a big COM-11718. :-)

    wild guess, is the wall wart unfiltered dc? a single diode turns the power output off 60 times a second. if your volt meter reads less dc than the wall wart label and or your volt meter displays a significant voltage on the ac scale, that maybe the problem. try a capacitor on the wall wart output.

    My Tenergy AA-AAA charger blinks to show power on. Off when empty. Steady red when not charged. Flashing red when something is wrong. Then green when that one position is fully charged.

    how about a safety video. electrolitic cap backwards, wear safety glasses before it detonates. slow motion of where the leads go when you cut them off. of course no one would ever drop hot solder in their lap. ;-)

    Ah pinballs of the 70’s when I repaired them. Found Nixie tube circuits that shorted in high humidity (acid core solder), repair notes in Spanish, and a mechanical machine from a bar someone used WD40 to clean (the can says “cleans and protects”). The protection is a form of varnish the does NOT conduct electricity. I like the new boards with HDMI output to a monitor in the headboard. Flexible enough to support more than one game and a plexiglass protected play field that could support imbedded displays below. That could help keep it more flexible when an ‘oh wow’ idea comes in late in the design. Good Luck.

No public wish lists :(
