    Solar garden lights with deep discharge protection?

    I am wondering if there are any solar garden lights which have deep discharge protection for the battery.
    Many solar garden lights do not have deep discharge protection, as far as I know.
    My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

    Christmas lights - Something I am doing wrong
    by Francesc V.
    Hi:

    i am trying to repair this Christmas lights from my parents. They are incandescent lights, no led lights.

    I have tried with 12V a 24V small lights that I found in Aliexpress but is obvious that are not the right ones. They last microseconds connected. Do they blow because of Amps or Volts?

    If I measure the Amps in the string........it's only 90mA. If I measure the Volts in the "green box"......it's between 0 and 190V, but doing a little bit of maths from the number of bulbs in series.......it's only about 6V per lamp.

    Could...

    Lenovo ThinkPad E14 Gen 5 - Not Powering On - 3 Blinking Lights - 20 volts 0.224 amps
    by bialag
    Hello,

    I have a Lenovo here that does not want to power on. The motherboard appears to be clean, no sign of corrosion or obvious fried components. When plugged in, I see 3 blinking lights and then off. It would cycle the 3 blinking lights every 10 seconds or so as long as I have the adapter plugged in. Amp meter shows 20 volts, 0.224 amps, no fan spin, red light indicator near the charge port.

    Thermal camera shows a section of the motherboard that is warmer than the rest. It is near the connector labels JRTC1 (CMOS battery). Diode measurement to ground for pin 1 = OL,...

    IMAC A1418 / MB: 820-00430-a / does not turn on, Lights 3 of the 4 LEDs and turns off.
    by gabrielA7
    Does not turn on, lights 3 of the 4 LEDs and turns off and stays like this, presses the power and repeats.
    I saw that the room LED lights up only when the screen is connected, so quiet.

    We have all the power supplies, even processor, 1.8V
    One thing I found strange, it has a very low resistance in the Vcore is giving 1 Ohm , work with notes and such, I know that this is normal in some processors but with this resistance only take video card so found it strange.

    I suspect that there may be some leak in the processor.
    Anyway, when I press the power, it...

    Making a capacitor discharge tool
    by redwire
    I'm making a new capacitor discharge tool. Asking for suggestions for sizing the discharge resistor.
    Mr. Carlson's Lab High Voltage Capacitor Discharge Tool 1 is using 4 of 1kΩ 50W aluminum (mount to heatsink) resistors in series for 4kΩ 200W, so it's big, which is fine.
    His Patreon but I don't have a paid subscription for the project details but it looks straightforward. The plastic box with aluminum plate can't get rid of any amount of that heat though.
    Wirewound resistors can be overloaded by a factor of 5 for 5sec. and a factor of 10 for brief times. I've never tried say...

    When your mom is complaining about her new cheap lights
    by evilkitty
    My Mom bought some cheap motion sensor lights on wish... then complains about about batteries and this thing chews though them, well it uses 4 AAA batteries and a pack of rechargeable ones is about 13 USD

    well since it uses 4 AAA and rechargeable are 1.2v and non-recharge at 1.5 this thing must work with 4.8-6v, I'll shove a USB cable on it, infant i will use a broken phone charge cable... dam this thing uses 430 mA and they made it battery powered...


    lets ignore the fact that i thought the board fit both ways... and the wire color is reversed going to the board...
