...without the use of any electrolyte (as sodium carbonate, commonly used for improving water conductivity), to accomplish this the generator will perform a calculus operation integrating the current/time curve, this is determined by several physical constants: Avogadro's Number, atomic weight of silver and Coulomb. The software or HMI, should run several processes simultaneously including an ammeter, voltmeter, touch screen keys, time remaining clock, current/time integrator, and audible end of run indicator. The current limiter could be changed during a run. The current may be driven by an op-amp. The cell voltage should be at least 10v (based on an electrode separation of 1,5 inches), 28-30v is desirable. This will be accomplished by a voltage multiplier built in into the ci...
Cost effective and very accurate Voltmeter, Ammeter and Watt meter combined circuit, with 0-5Volt DC output to control Voltage and 0-5 Volt to control Current from a DC power supply. It has to be designed to show the parameters by an adequate graphical display. Two rotating encoders to be provided to control both voltages of 0-5 volt and the center switch within the encoder to be made toggle for the Coarse and Fine settings. Display resolution for voltage should be 00.00 Volt, 00.00 Amps and 4 digits to show Watt. An image is attached herewith for your reference.
My project is about troubleshooting an H-bridge motor controller circuit with an dc motor that is fluttering the rekays when a load is applied. The voltage of the motor is 24V, and I have a schematic available. I need someone experienced in electronics engineering to help me test and troubleshoot the circuit, and I will provide a voltmeter for them to use.

On the picture "Voltmeter" you see the scale of a gauge that I bought recently. Your task would be to adapt it to the style of the car. a) for the shape of the scale I need a file in DXF. The diameter is 55mm, the inner hole may be 6mm. b) In PDF I would like to have the new design. Please compare with the "green-and-red" picture, which gives you an idea of the original design. There should be an inner ring in green (from 11.5 to 13.5 V) and in red color (all the rest in both directions). Maybe better fonts, all of them in white. c) Add lettering "Voltage" and the DS logo. Easy for you, isn't it?

I require an engineer to provide tutoring to staff on calibration of measuring instruments such as ammeters and voltmeters
There are a number of VNA projects on the internet that produce smith charts for various configurations that use a single directional coupler . HP's application note provides a technique for producing transistor S parameters usine a signal generator and a 8405A Vector Voltmeter. The compelexity of the 8405A Vector Voltmeter can be significantly reduced by the use of an open source VNA most designs use a single directional coupler and a second is required to test transistor output impeadance. I am looking at the NanoVNA2 or one based on Henrik Forstén project there is also a thesis from Josh Johnson using an AD8302 this is limited to 2.7 Ghz and is sufficent for most applications

...between the PSU and the POE board and by an 8 ohm variable pot hold the voltage down to near 52. The owner of the faulty PSU's has over 1000 in his warehouse and may not be prepared to bother with the above solution, even if it works but will then be in the market for a replacement 52VDC regulated PSU. If he opts for a total safe replacement then my scheme is still viable, for by adding a cheap voltmeter and a cheap ammeter we have a cheap variable bench power supply of about 0 to 60 VDC at 1.85 amps. Depending on the loss across the 783, or whatever regulator is selected. Cheap if the owner will sell the faulty PSU's for peanuts. Apart from the wandering DC output they are fine. I have a test rig set up to test a prototype with an 8 port SOE and eight cameras, but...

A single phase submersible pump control Panel will protect the submersible pump/motor from dry running, overloading with the use of micro controller. It must also show the voltmeter & current taken by the motor. Additionally, a timer facility is required, e.g. after electricity comes the motor should not start instantly, it should start after 3-4 minutes. PIC controller is more preferable.
