Here we go again.....with some 'lite' humor. If you put a light bulb in a light tite box does the light level increase because the light is being stored inside? If this is so than the light switch on a refrigerator door must be a safety device to prevent that blinding flash when the door is opened. ...

WOW! PTS is stll around? Is this the same Precision Tuner Service from years ago? I sent them a ton of barrell and wafer tuners for repair and rebuilding. Many had bummed shafts where a knob was lost or broken and the kitchen drawer pliers substituted! I still have, and sometimes use, their famous '...

Now let's recap a bit and put it together... Some of these are interrelated so they are not in a logical order, but here are some points to ponder. Unless you live near Roswell NM, the LED must be getting power from someplace. I doubt that, unless you are next to a big transmitting antenna, you will...

Indeed there are variations, and if you go back two weeks later, the big box store may not be selling the same product. Yes, there may be an 'equivalent' product on the shelf but there can be differences due to production times or the manufacturer. I once bought some prefinished shelving, then a few...

Hi John, By no means am I a Xbee expert. This evaluation kit was obtained to prototype a design that never matured. I did set up a link to prove the concept but no other testing was really done. I would estimate the total power on time of two of the modules was only a few hours and the rest were nev...

How about a large value, low leakage capacitor, directly across the sensor to slow down the swings from the light changes? :idea:
Or add a filter to the sensor lens to tame it down a bit.
No, I don't think there is an optical capacitor :sad:

Actually the mechanical part would be more challenging then the electronics. With cheap off the shelf preset counters you can count the turns of a wheel and then cut at the preset value. Add a batch counter and it will stop at the desired quantity. I have the AM-10 pneumatic crimper (see other posts...

Perhaps a shorted capacitor has 'healed' itself.
I have seen this with HP systems and their crappy capacitors.
Were I you, I would not get a block party permit just yet! :mad:

With the Vizio there are built in apps for YouTube, Netflix, Hulu and many others. No, you cannot surf the net but there is still some free content available. There is a app manager that allows adding or deleting apps. Connection is via a wireless or wired connection and there is a complete network ...

I need two predetermined, also know as preset, counters for a wire measure/cut project. You set a number, count whatever and something happens when the count is reached, then do it again. My knee jerk first thought was to get a micro, keypad, display, a fist full of other stuff and then crank out po...

i Len, I am not sure what you are trying to say about the lightening.... Metaphorically speaking, have you never KNOWN that the guy climbing the broken ladder with three cans of paint, hands full of brushes and hanging loose shoe laces was going to have a disaster? As to the 'lick' factor.... I'll j...

What I know about the lightning ..... Check for home owner insurance discounts, like for an alarm or fire protection. For a lightning rod, usually there are none. Often rods are found on old farm houses and tall smokestacks. On tall buildings they use antennas! :!: One time lightning struck the grou...
