    Look for a WiFi Signal Strength Meters

    UPDATE. . . . . . . Steve said . . . . I also saw (a week or so ago) a design for a spectrum analyzer using an NRF24L01+, but I can't find it now :( So I went to that link and found his link . . .at that time . . . has now been replaced with a GAMESTOP page...

    Looking for RCA Chroma IC Datasheet

    Maybe a year late but . . .found you while searching for other post You are going to have to use the LA7615 equivalent schematic / data sheet of that A23110001A RCA jungle chip http://html.datasheetq.com/pdf-html/437011/SANYO/20page/LA7615.html?lang=en

    I'm new and need help with a capacitor

    From what I can make out from the photo, is its center all pooched out and is the unviewable far side, possibly, being split ? This one below meets X2 line cap specs and tolerances and even excels on the all important AC voltage spec. If yours is not having this 15mm lead spacing, check for...

    Simplest mosfet circuit with ghosts....

    Sir punkieys17 . . . . . . I would be first wanting to know the voltage /current/wattage and run capacitance used on that motor.. Let's do a test . . . If it's going to be using that same SCR, I would swap the AC line input at the top so that you would then have all of that circuitry...

    RCA F19207BC (CRT TV) shuts itself off even after new HOT install.

    No response to my PM / Conversation to you for info, so I'm burning a post and re posting here. Seems like Ruh Cee Aye made a change to your sets CTC 185 chassis and Q1114 was changed at later dates . . . . Initially the sets Q4114 was being a bipolar # BUH517D and then later they changed it...

    Trying to repair a circuit board for a rolling ball clock

    Sir @Iguanaman . . . . . I wish that I could have had your last pic for referencing, earlier. That holder seems to be for "D" sized cells, with 3 and then one on the end. And is the silver mylar sticker stating 6 VDC @ 100 ma ? I can see the barrel connector input plug and there being the...

    Basic: Trying to hookup 20v Decker lithium battery - to a 20V four wire Hoover vacuum. Same parent company.

    Looking at the third photo down and the black vacuum orifice and then comparing it to the slotted cuts surrounding the battery . . . . surely you're loosing ~ 50 % of your suck capability with that air leak fallacy.

    Sir HarveyCat . . . . . . . What I am seeing on your last picture . . . . . is being the money shot. On the bottom corner left is heavy RED cable that should be the 5 X 18650 battery packs + output and the heavy BLACK cable which should be its - output. The RED wire goes up to a power switch...

    Trying to repair a circuit board for a rolling ball clock

    Sir @Iguanaman . . . . . Most humble apologies on the time offset delay . . . . of reply. Looking at your soldering, I believe that we can now not worry about the possibility of a solder joint connectivity issue. With concentration now being on two aspects . . . 1. The provision of a...

    Help identify [SMD resistor?] Please!

    The last nickels worth of your query . . . . . is there a specific orientation to this part? Nope . . . its non polarized and I usually use a round tooth pick pressed down on its center to hold it in place, until I get the mystical and magical Pb Sn concoction applied to its ends.

    Help identify [SMD resistor?] Please!

    What I am seeing is a monolithic block ceramic capacitor, most commonly used for bypassing and MOST commonly, statistically used, being a 0.1 ufd at typically a 50VDC rating. Next most likely a 0.01 ufd unit . That might possibly even work without it. It is not as likely, as if it was being...

    Need help troubleshooting control board

    O.K. with this posting JUST dedicated to the 4 wire connecting plug over to the control board And the use of the two side by side pedals, which I presume to be located down near the floor for shoe toe operation, to leave both hands free for use upstairs. I can see the sharing of a common wire...
