I need a board with a custom remote control that will operate items running on 12 volt dc. It needs to play different sound bytes by clicking diffent buttons. Also needs to turn 12 volt dc lights on/off and brighter/dimmer. Also would like to add a movement sensor that can be wired in to the board that when it detects movement it will play a sound byte and also turn on 12 volt dc lights and then shut off everything in 10 seconds.

The specification is as follows: PV voltage: 25-50 volt with 1 KW output power over the voltage range Load: ±120 V split single phase ac (60 Hz), <1 kW average and 2 kW peak power Battery voltage change range: 1-1.5 and max output power: 1 kW All capacitor voltage peak ripples: < 5% All inductor current peak ripples: < 50% (SEE PDF ATTACHMENT FOR FULL SPECS)

Developer a microcontroller (in the beginning could be Arduino, etc. - later own controller hw) application that does control temperature on a device and modifies performance settings (volt, amps) based on some characteristics. It uses input and output information via a touch display or OLED/steering buttons. Needs to control also a few actuators/relays.

I am looking for someone who could help me with a small project and design a CM4 carrier board with few additional components: - CM4 connector - Mini PCI-E socket with SIM card holder - 2 x Power input (~10 to ~ 30 Volt). State of both connected to GPIO pins as signal (so reduced to some ~2 Volts) - 2 x I2C exposed - Battery charging controller. The main power reduced to 5 V, then connected through the battery charing controller back to the board. - MicroSD card socket. - SPI exposed - Few (~5) additional GPIO pins exposed.

i need a device that when it senses 110 volt power it will keep a running total of hours run , it will be on,off,on,off like the odometer in your car , only runs when power is sensed . it needs to have a resettable alarm that will flash the display or a led at 500 hours, at 550 hours i want an audible alert [beep] that is continuous until reset. i can build it i just need the components required , the schematic and the code for arduino or rasberr pi

Dear Saddam, as discussed yesterday I would need your support on my Fuel Cell model. Target it to set the ref. builder to a certain value which can differ to the req. builder. The reference builder is controlling the FC where a power output of up to 3 MW should be achieved. (status quo) The task will be to modify the existing model so that the Units ( Ampere / Volt / Pressure / Liter / Flowrate) will be displayed correctly in the plots. (Validation of results necessary)

Inverter RS Smart Solar 48 volt / 6000VA Need an Engineer with Victron Knowledge to do the final setup and checks before system goes live UK (Kent)

Hello, following project: 12x Servo Motors (660W) sh...now I am coming to the 48V power supply: I found this 48V alternator like: 7.5kw 48 volt 200a Alternator And now I am not sure, do I need a batterie between Alternator and Servo – if yes how big should be that batterie (maybe 4x12V batterie) Do I need a reverse current switch? If yes – which one? Do I need a charging current controller? If yes – which one? Is the alternator big enough to powering that 12x Servo Motors – working all the time? There are some addition parts that I need? ... ... The goal: A calculated plan/system that I can powering those 12 Servo Motors without problems :) Thanks Here the Servo Motor:

You need to be mathematically skilled as well as knowing how to make a video. I would like to show the difference in your electric bill where you pay for Apparent Power (S) which is a function of Active Power (P) and Reactive Power (Q), so the function is S^2=P^2 + Q^2 or then S=SQRT(P^2+Q^2) It needs to show how the electric current normally has its fluctuating voltage U (in Volt) and current I (in Ampere) oscillating in a perfect Sine-wave when you ONLY have pure resistive load (e.g. heating) but how there is a phase shift oscillating between 0-45 degrees when you have inductive loads (e.g. motors, welding, compressors, transformers etc). Since the phase shifting will be going between 0 and 45 degrees the whole time, I want to show how the electric bill is normally averaging...

Need circuitry designed (PCB Design) for multiple units of remote control, pan tilt spotlight, two boards in total, one is a remote control that has a joystick that drives the two motors, is rechargeable and runs off of a 18650 battery, and is able to turn the light on and off, the second board is for the body of the light, mounted on a roof, this board runs off of a cars 12 volt system, and just uses alligator clips onto the cars battery, the light being used is around 2 kg, however, motors need capability to move about 3 kg, the x axis, pan motor spins 360 degrees and uses a slip ring for the tilt motor to get power, and the tilt motor is less than 180 degrees.

I need to run 3 circuits in consecutive sequence at the rate of 60,000 cycles per minute. In other words, power must run through a single circuit, disconnect that circuit and connect the next (2nd) circuit, disconne...the 3rd circuit, and then start all over again, and do this 60,000 times per minute. This is using 12 volts DC, 60 Amps. I also need a variable speed control for the speed of the sequences so that I can run it at a slower speed of sequences if desired. I may decide to use 24 volts and 30 Amps instead of 12V/60Amps, or I may use a combination of the following. I am running this off of five - 12 volt, 12 Amp lithium ion smart batteries in parallel or sequence, to get the desired voltage/amperage. This sequencer and speed controller that you build, must be as portable as...

I am doing a project that involves a solar panel. I need an engineer to calculate the amount of power that can be generated by the solar panel compared the power used by a 12 volt generator

Hi. I am looking to send 8 pairs (16 in Total) of sensor data to MSSQL. This project is to measure the cycle time on an assembly line. Each pair consists of a 24 volt sensor and a 24 volt push button. The 24 volt sensor activation time is the start time and the push button press is the end time. Ideally I would like all 16 sensors to connect to 1 board whether its arduino or Raspberry Pi and send to MSSQL via ethernet. These 8 pairs of sensors span approximately 50 meters. (Will this cause transmission loss?) I have an MSSQL set up already but I am unable to get the data from arduino to MSSQL. I have attached a file.

For the Cybertruck and the Semi, Tesla is contemplating an 800-volt architecture. During the investor conference on the latest quarterly figures, Tesla manager Andrew Baglino stated this. He also spoke about the importance of 800-volt considerations for other models. Tesla's annual report for the first quarter of 2022 was released on Wednesday evening; even when compared to the previous record quarter (Q4 2021), Tesla was able to boost profit by another billion dollars to $3.32 billion dollars. In addition, sales reached a new high. The points the firm provides in the investor release, as well as the statements made during the accompanying telephone conference, are traditionally interesting in Tesla's quarterly data. Other companies, on the other hand, feature m...
