    Battery resurrection

    I knew you're going to say that. In truth my Crystal Ball knew. My goodness all these naysayers out there! I have personally built an anti-gravity car powered by an anti-gravity rejuvenated lead acid battery. And it works. But all it did was drive me up the wall!!

    ESP32 wroom32 Bluetooth dBm

    You could use repeaters. Or external power amplifiers DIY or buy off the shelf that goes for any adreno or raspberry pi But you wouldn't want the FCC knocking on your door. That's going to the dark side , I did read somewhere the dark side has cookies. Yummy!

    ESP32 wroom32 Bluetooth dBm

    Look at page 12 there's no default .it's normally a range (minimum, typical, maximum) Max transmitting power is +10 dBm that is the Gain of the transmit amplifiers output with reference to its input which is one milliwatt. That's what the m stands for in dBm. And this all depends type of Wi-Fi...

    Speaker LED lightguide frontplate

    I used to think physics was kind of difficult.Helping is harder. Could you please take a photo of what is behind your Thank you! & I appreciate this clarification 3 mm = 0.11811 inches or 3/32 seconds of an inch. That's one heck of a strip. Now if you'll excuse me, I have to get back to my...

    Speaker LED lightguide frontplate

    Great now you tell me. Anyway. So 3 mm White LEDs light sources those are characterized by temperature in Kelvins. Warm white(2600K to 3700 K ), neutral white (3700k to 5000 K ) & cool white (5000K to 8300 K) + Diffuser, which is your laser cut lightguide pattern of 45° angle of incidence...

    Speaker LED lightguide frontplate

    Forget what I just said... let's start over. The image looks horrible. How thin is super thin for the light guide, could you volunteer the manufacturer specifications. LEDs as well. Any and all information you can provide would be most helpful. Show me a photo of what is behind the light guide...

    Speaker LED lightguide frontplate

    Or you can try some thousand grit sandpaper scuff up the individual LEDs themselves, try a single LED first see how effective the light will disperse. Trial and error and go from there!

    Recreating kit sold in the 60s, alt 12vdc to 3 120vac outlets

    As mentioned above the frequency will be dependent on shaft speed or rotation of the alternator. You say three 110 AC outputs. which gets me thinking about, I think (I'll have to check with my grandpa) back then some alternators output Polly or three phase & terminate to a three-phase full wave...

    buggy board, bad tech and strange readout... heh heh

    Hey...I resemble that remark! do you mean the controlled feedback concerning the amount of energy that must be moved varied on the desired temperature of the cooled space, the ambient conditions, amount of humidity etc, and the level of internal heat generation within the cooled space perhaps...

    T110C Hand Held Remote Transmitter

    From what I gather on an interweb. www.omnexcontrols.com Omnex t110c Hand held transmitter have unique ID code for each transmitter/ receiver pair to ensure no two systems will conflict with each other on the job site. Employing frequency hopping spread spectrum. I can see why you asked for...

    Where can I find this Component (Inductor / Choke)

    Aah so true. The values of those components are there by design! Without a schematic. there is very little one can do. If you're proficient with a oscilloscope I can walk you through the process to confirm or deny your suspicions. If you are in the US you can try Digi-key or Mauser for...

    Where can I find this Component (Inductor / Choke)

    Replaced the entire video graphic card! One or more of the components are faulty. I see capacitors associated with the inductors lower right hand corner designation c571 that is covered with a non-conductive blue pad. ( the only one I can see clearly.) To comment any further would be total...

    what is value of variable resistance “VR1” in Powercom UPS BNT-1000AP

    I have no idea it's kind of hard to see from here you got a photo of VR1? Or number markings on it like 403-302 something like that?

    Battery resurrection

    There are many factors that contribute to poor battery performance and failure, & it is important to diagnose the symptoms of poor battery performance before determining a cure. It is also important for amateurs to understand that many of the supposed “cures” can damage the battery, while...

    Battery resurrection

    My totally discharged lead acid batteries through a very complex process and should not in any way be attempted by amateurs... turn into boat anchors. I would agree with Battery University.
