    Help, accidentally connected 24v to a 12v ip camera and now it won't turn on.

    I don't think that you will be finding a "freebie" in any other "things" that you have laying around.

    Help, accidentally connected 24v to a 12v ip camera and now it won't turn on.

    My . . .my . . .MY ! . . . . . you really DODGED a BIG bullet on that one ! That would appear to be a Transient Voltage Supressor installed across the supply line. Check out Littelfuse as the BM marking code is referring to one of their 15V units Make REFERENCE to their SMF series @...

    Sir Agnatorian . . . . . ¿ Whyforyounogivemonitorsbrandandmodelnumber ? ¿ Whyforyouhavenewcapacitorswithfulleadsandyoutheninstalltheminthatcrudeandslipshodmanner ? Guess that leaves me to relying on my "reading of the board" and guess that the unit is a KB monitor using a TUO8Q164 P.S...

    Storz & Bickel Plenty Vaporizer Circuit Repair

    ADDENDA . . . . Considering the small size of this unit and its handle aspect . . . AND a TEMP gauge ? its not being my expected conventional water vaporizor . . .but an electrified HOOKAH ! I hold the same suspicions of an isolative / thermally insulative build up still being at the bottom...

    Storz & Bickel Plenty Vaporizer Circuit Repair

    Sir Kurt . . . . . so I assume it is the themal fuse causing the problem. If you are getting any level of heating, it will NOT be the thermal fuse, with it being bad, the unit will be stone cold dead. PARTE DEUX . . . . relying solely upon the infomational aspects of . . . . both had the...

    sunbeam electric blanket no heat

    Sir jon5500 . . . . . et al That is going to be this family of unit . . . . and NOT the previously reference to a SMD . . . version of a lower voltage rated 2N2907. Since the potential full AC voltage of the heating element string is going to be across / sampled by it. PLUS I really...

    Fluke 8846A defective due to overvoltage

    There are also 2 letters printed on component Q41. But the photo reflected it. You have to moisten the component and illuminate it with a lamp, then you can see the imprint. If that was being the case then, and you WERE able to make them out, why didn't you give those two alfa /numeric symbols...

    Gould Model 465 Oscilloscope

    Sir fmevanspe . . . . . OH TAY ! on your forthcoming comments and the similarities / disimilarities of the supplied GOULD 400 series power supply . . .versus your 465 version. I would at least suspect some high degree of carryover of their shared initial design aspects. Now with your...

    Solar cell soldering

    First you initially see that your solder drop fully flowed into and blended in with the cells solder coating. Then the only thing that I would do differently would be to ADDITIONALLY flux the silver wire and solder tin coat it , until the point that you can see that it is then FULLY solder...

    More transistor radio repair - faultfinding prior to audio stage

    That is EXACTLY correct . . . . . so it seems that the to be repaired Punysonics local oscillator IS functioning properly. So . . . . . can you now pick up the harmonics of an IR remote transmitter that will / can extend on up into the tested radio receivers IF spectrum ? Standing by . . . ...

    More transistor radio repair - faultfinding prior to audio stage

    Sir de_light . . . . . Well it looks like you have moved up from the last sets less than desirable germanium transistors and now graduating into more modern SILLY -CONE transistors. I do see a lackluster wide band frontal RF amp stage that is not even using a tuned circuit in its base input...

    Sansui 7000 Receiver with weak FM

    You'se guys . . . . . Mine eyes show that to be having a pop off / wrap around tuner shielding. If that is being a TO-72 casing schmitt der 4 gold flashed leads . . . as a dual gate MOSFET . . . . . . I am still havink sum left over from my ham radio days. I initiallly was expecting it to...

    Transistor radio repair - Philips RR-230

    If it wasn't cut or broken you should just be able to route properly and leave the last to getting it upon the BIG tuning pulley, where a light pulling on of the associated tensioning spring should let you get just enough dial cord slack to then just roll it upon the drum / pulley...

    Sansui 7000 Receiver with weak FM

    Sir KilgoreCemetery . . . . . . Now I can't see, in order to know, if that units FM tuner is being all sealed up like sardine can . . . . . BUT . . . . if you can get access . . .first try this evaluation. Note the shared connective comonality of the drain of the RF amp and the 22pf cap and...

    What is this component

    That reminds me of a small wattage vitreous coated wire wound resistor. Pull all power and take an ohmmetter and see how close it comes to reading 330 ohms. . . . .or also possibly 33 ohms. If so then, tell us about the audio amplifier used in the unit. More info please . . . The parts right...

    Dewalt DC012 radio - No sound

    Sir Gilles H . . . . . Referring to the resolution limitations being provided by your . . . .DC012.jpg photo. Your fretting of the relays and hot resistor can be allayed as they are being associated with the tool battery charger portion of the unit. The sole radio aspects portions are being...

    Transistor radio repair - Philips RR-230

    Sir de_light . . . . . After hearing that, I would also like to see you either have the speaker out of its present circuit and test it with a like power level of low impedance audio from another source. BTW . . . . what is the impedance of the test heaphones being used . . . .low like the...
