The most prosaic reason why your cable doesn't work and is drawing too much current is that you connected he wrong pairs of pins and/or some of the the wires are shorted together. If that is not the case, there are two obvious problems: A USB cable that meets the specifications has two twisted pairs of connectors enclosed in an outer shield, not four wires ...

The device is likely not getting the power it needs. Use a thicker wire to ensure the resistance is the same as the original. Don't make an induction coil with your cable. It also helps to use twisted pair - see some of the faster ethernet cables for reference. You twist the two ends of a corresponding signal to preserve integrity. Since an approximately ...

You can do this with a pair of Omron programmable timer modules that mount onto DIN rails, no software required. They are extremely flexible and can be easily configured to perform a variety of tasks like this. They are basically a set of relay contacts which are exercised by an internal clock, packaged into a small plastic enclosure with a clock display and ...

An alternative to an H-Bridge (preferred method if you are already using a controller - it also lets you use those overkill relays for other projects) would be having +/-6V at the motor. This would mean a 12V supply with one leg of the motor at a regulated 6V. You connect the second leg to 12V for one direction and 0V for the other direction, getting you 6 ...

If I am not mistaken, you can use an H-Bridge for that. If you are using an arduino for example, there are a few motor drivers like L298N which do exactly that job (control the direction and speed of a dc motor).

An amplifier doesn't increase power for free. It takes a signal with not much power, and a power supply and outputs a signal with lots of power. The extra power (in fact, usually all of the output power) comes from the power supply. Where is the power supply for your amplifier? That is what is powering the whole system. You may as well connect it directly to ...

In general, it is not possible and it will not work because of law of conservation of energy. For every energy conversion, you will lose a bit of energy. You can invent many similar circular schemes, for example, solar panel - the light bulb, motor - generator, weight going down and from the energy getting from moving down, going up again, water going down ...

I would hope that the power lines are heavier gauge than any of the other lines. I would not expect signal lines to pass USB3.0 properly unless specifically stated. If current (i.e. power) is run through contacts designed to pass "dry signals" (i.e. zero current, no power) it ruins the contact surface so that it can no longer pass dry signals since ...

It seems to be a missing ... Wire from top R5 and collector of BC238. However, gain seems low ... -35 dB from 10 Hz to 200 kHz. Adapter for high voltage piezo or same.
