    Charging an iPod from 12V in a car

    Suggest get an adapter with at least 2.1A(2100mA).

    AMP connector identification

    AMP connectors often have the 6 digit part number hidden somewhere on them. Just need a magnifying glass to find and read it.

    Can CP2102 USB to UART be used to power 5V devices?

    Yes, the CP2102 board was powering the Arduino. Here is a photo of the programming board I use.

    Can CP2102 USB to UART be used to power 5V devices?

    A USB2 port can only supply 500mA. I use a CP2102 board to program and test run Arduino Pro Mini boards and stand alone ATMEGA328P micros without any problems. Just have to limit the output current to keep it well below 500mA. Must learn to type faster.:)

    Push Button H2O - Reversing Polarity

    Looks like Bob and I have been led astray by the ambiguous information given by the supplier of your valve. As you have discovered, your valve probably works by changing polarity. The wire colours indicate which way to connect power to get a particular operation. Just found this on another...

    Push Button H2O - Reversing Polarity

    Like Bob, I would be rather annoyed if I had purchased that solenoid valve and found that it only works by changing polarity. That is not how the description reads to me. I would also not have expected a polarity reversing valve to have a red and black wires. Another thought. The valve is...

    Push Button H2O - Reversing Polarity

    "Yes, I am going by what the link you posted said. Did you try to see if using the same polarity twice also might flip it? Because that is what I read the specs as saying." Have you tried this as requested by Bob? Confirm state of valve, ie open or closed. Connect the black wire to negative...

    Home Security system takeover

    Why do you not want to call Monitronics? My suggestion would be to call them and find out for sure what the situation is. Can you contact the previous owners? Real estate agent may be able to help?

    Home Security system takeover

    Do you actually own the system, or was it a "free" supply and install with monitoring for a set term?

    Connecting strobe light to 12V vehicle reverse lights

    I'm a little confused by your diagram. Each bulb is shown as having a chassis earth and an earth wire going back to the flasher unit's output. These earth wires appear to be joined to the bulb contact wire? This is a direct short, so can't be correct? Do you have a link to the flasher unit?

    Effectively defeating PWM on Jeep Wrangler

    Is the problem with the original halogen headlights poor output brilliance, or poor beam pattern? Better quality bulbs may help to increase brilliance, but there isn't much you can do for crap design. Halogen bulbs have a filament that heats up to give out light. The filament heats up and...

    Effectively defeating PWM on Jeep Wrangler

    Would it be better to use the PWM to operate a relay? The relay contacts could then supply direct battery voltage to the LED lights.

    Exam question help please?

    My opinion is that it is a badly written question.

    48v DC - what switch do I need?

    Make sure you fit a fuse in the positive wire to the 48v-12v reducer. The fuse should be as close to the positive take off point as possible.

    Inductive sensor interference

    Usual method is to use a shielded twisted pair cable from each sensor to the module that is reading the sensors. The screen should be grounded at one end only, probably the module end. https://www.altex.com/Belden-18AWG-2-Conductor-Shielded-Twisted-Pair-Cable-8760-BEL-P140298.aspx

    Speedy PCB production using an inkjet printer

    I have got to the stage where I am starting to look at making my own circuit boards, rather than using veroboard. Boards will mostly be based on an ATmega328P-PU chip. Some may have an Arduino Nano or Pro-mini instead. Q1 - What software are you guys using to design the board? Eagle, Design...

    Wondering if a Pyle Pro Amp is Compatible with Some Sony Speakers I Have

    Probably should be ok. Speakers are 3ohm and rated at 143watts. Amp is rated at 120watts into 3ohm speakers.
