    Try measuring the voltage over the black diode, it should be "1.2-1.5VDC".

    18650 charging question

    Your power supply can not provide the needed current rating, but it will still work. This is made for charging 3 18650 batteries in series, if they are charged to "4.2VDC".

    ADC Values?

    This is a little unclear. 1. Whats your power supply? 2. 99 only means that you need 0.32V for whatever you are doing, if you need something else, change the voltage.

    Flash varification error for atmega128

    Hi, 1. Please post a circuit. 2. Please provide your OS and PC type. 3. Is the processor connected to anything else but the programmer? 4. Can you test with a second processor?

    Can't find mosfet info

    t430: https://www.tme.eu/en/details/aot430/tht-n-channel-transistors/alpha-omega-semiconductor/ Are you sure the others are transistors? Don't use "bing.com". Use "google.com".

    Star Shower motion button bypass

    Thats done on purpose. A relay or Timer555 would be better. What is the power supply? If its "5VDC" a "T trigger" will do the job.

    Laptop as a Playstation (PS1)

    Converting the cable is not possible. Windows 95 and 2000 are not recommended. If you can not get at least Windows 7, you may have problems in the future. If the emulator works for Linux "Ubuntu Linux" is a better choice than Windows 95. You need a software similar to "JoyToKey". Plug the...

    high side mosfet offset voltage in Phase shifted full bridge converter

    Designing a full bridge inverter is not an easy job. Can you post a circuit?

    LCD replacement

    It shouldn't be possible to use it with a smaller one. The resolution does not matter as much (if the controller is made for multiple resolutions). But a different inch display should not work. Make sure that the connectors are exactly the same, if they are and the old chip is made for multiple...

    Simple DC-DC Boost Converter 19.50V(dc) to 20.50V(dc) and 8A for charger.

    I don't pretend I read your posts. Normally the simpler method is to take it from the input, but it might not be possible in your case.

    hi fellow hobbyists.. ?about sensors

    A simple LM358 as a comparator will do. You need resistors, the IR LEDs, an LM358 and the LED for lighting. Like this circuit: http://elonics.in/breadboard-projects/infrared-ir-proximity-obstacle-sensor-using-lm-358

    Increasing Battery life Question

    "24A" for half an hour, which is very unlikely. It might be time to replace the batteries with rechargable ones and buy a car cigarette lighter charger for "9VDC" batteries. I will post the links for them later. Isn't 12A/h too much? I see them with 600mA/h ?

    Send Wireless temperature sensor to Industrial cloud platform through REST API

    I am not familiar with Raspberry P. If you were using a different WiFi module it would be possible.

    Send Wireless temperature sensor to Industrial cloud platform through REST API

    I have to check the datasheet for your sensors, to see how they work. Normally: sensor -> wifi module -> router -> web server -> something in the web server processes them.

    Whirlpool topload washer motor

    That would be very hard. If possible connect everything to the original washing machine and try to measure what does every wire do. We don't have that knowledge unless there is someone who has practically repaired washing machines, especially this model. Disclaimer for the stupid: Do this at...

    Suggestion to send wireless Temperature sensor data to google spreadsheets

    Also a circuit would be useful and some effort from you side. We don't want to just do it for you!
