Loading...Hello, if you read my last post you know my project. I plan to transmit energy over an air gap of about 2-3cm (up to 2 amps) In keeping with this, I am currently researching and conducting experiments on resonant circuits. I am able to create and modify these resonant circuits by changing the capacitance…
If a day has 24 hours, how can I supposedly have 23 hours and 59 minutes of screen time?
Hi, I need to install a warm-up circuit with a buzzer for a technical project. The total voltage is 9 volts. The buzzer is 3 volts. I also need to install a red LED (1.6 volts and 20 mA). And the potentiometer (10 kOhm), but I only need 2 kOhms. In the end, it didn't…
So, we're soldering a Christmas tree at school, this one: " https://www.roboter-bausatz.de/p/bausatz-led-weihnachtsbaum " and my friend put the transistor in the wrong way round, so I soldered it like this. We noticed it and tried to re-solder it, but now the transistor's legs are so short (we had to cut them off) that it no…
Hello, I have a Xiaomi 11 Pro with the included power adapter. At first, it took an average of 16 seconds to charge to 1% (I used a stopwatch). Then I plugged a Huawei phone into the same port a few times. Now, my phone takes 30 seconds or more to charge to 1% with…
