...program written for a raspberry pi zero, that will be plugged into a TV via HDMI output. I want the Pi to output a picture to the TV, in JPEG or PNG format, then when the PI receives a signal, it dissolves the image to show a new image, which will be a logo. Then after about 5 seconds it changes back to the original picture. The signal the PI will be watching for is a drop in voltage, from 12 volts to 0 volts momentarily across 2 wires that I can input into the PI. I would like the ability to change the static picture out, but the logo picture will remain the same. This is for a Samsung Frame TV that is on a door displaying art. When the door is opened with a RFID card, it releases the door lock (this is the drop in voltage from 12 to 0) and I want the logo picture to dis...

I've purchased an inexpensive DC power regulating board, 12 V in and 0-12 V out. It has a pot you adjust for the output voltage. I want the output to slowly build from 0 to 12 volts over about 10 to 20 seconds. I decided to swap in a slow RC circuit for the pot. It does NOT work. See attached pic. I think the pot is just a variable resistor as the wiper and ground leg of the pot are connected. The board was purchased on ebay: XH-M400 for about $8. I think you would have to purchase a board and experiment with it. The result should be when you put 12 VDC to the board, the output should slowly build to 12 VDC over a 10 to 20 second time period. It does not have to be linear. I would expect it to somewhat follow the characteristics of an RC filter.

...detail at ends. Originally two large cooling towers were placed over the boiler house to cool the water from the condensers of the turbine and the engines, rising majestically into the Glasgow skyline. It was designed by Andrew Myles and completed in 1900. In 1904 an additional steam turbine of 1,400 kilowatts capacity wasinstalled powering a turbine that drove two DC dynamos, giving 500 to 600 volts to power the south side of Glasgow for just over 20 years. The power station closed in 1922, however it wasn’t until 1937 that it opened its doors once again, as a Printing Works responsible for much of the stationery used by the City of Glasgow. Being a single-storey building the layout lent itself perfectly to its new role. This impressive and imposing structure is to be re-p...

In electromagnetism and electronics, electromotive force (also electromotance, abbreviated emf,[1][2] denoted E {mathcal {E}} or ξ {displaystyle {xi }}) is an energy transfer to an electric circuit per unit of electric charge, measured in volts. Devices called electrical transducers provide an emf[3] by converting other forms of energy into electrical energy.[3] Other electrical equipment also produce an emf, such as batteries, which convert chemical energy, and generators, which convert mechanical energy.[4] This energy conversion is achieved by physical forces applying physical work on electric charges. However, electromotive force itself is not a physical force,[5] and for the current ISO/IEC standards consider the term deprecated, favoring the names source voltage or sou...
