...transformer windings based on the detected input voltage. The possible voltages are 100,110,120,200,208,220,240. It is envisioned that an Arduino (which could be embedded into the circuit) of whatever flavor is used to select the voltage based on the sensed voltage. The circuit should be able to handle around 10 amps at the 200+ Level and up to 21 on the lower voltages. You will find a spreadsheet attached, which shows the color code for the transformer as well as each of the connections that have to be made. Connections to the supply are coordinated and they follow the diagram as shown in the attached spreadsheet. This is AC voltage and so appropriate Triacs will need to be turned on and off based on the voltage sensed. As an example, if the detected ...

...motor based on liquid level in a tank. More specifically, the following is the functional logic requirement: 1. Sense liquid level in a tank (15 cm to 1 m). The sensor should be non-contact type, for example, ultrasonic sensor. The selected sensor should be water proof as water may splash over it. 2. Wireless transmittance of the above sensed signal to a motor control unit. The distance is 30 meter and building walls would be present in between. 3. Motor control unit - Should receive the water level, and based on it, start and stop the motor (1 kW 1 phase). Detailed logic would be shared latter. 4. The water level should be communicated to a smartphone (Android/iOS) through Bluetooth. The smart phone will be present near the motor control unit. 5. Note - The system for sen...

Hello need overvoltage protection and reverse polarity protection added to an existing pcb design. It's a generator controller that is powered by 48-60vdc. As the generator produces DC, it needs protection from overvoltage in the following scenario. If the 48v battery bank is disconnected whilst engine is running, the voltage will rise above 60v damaging the onboard regulators(1 * 5v and 1 * 12v). I want the Vin to be disconnected immediately upon an overvoltage scenario with autorecovery.

I am constructing a permanent magnet generator but the generator experiences a voltage drop on load which is normal. The prime mover of the generator is a DC motor. I need a Arduino hardware that can read the output voltage of the generator and if the voltage is below a certain level, the Arduino should increase the voltage going to the DC motor so as to increase the speed of the motor.

I moved into this house in September 2020. The house was built in 2016 and has solar panels on the roof. There's an on-off switch on the top floor, but there's no meter for the solar panel anywhere. Neither my smart electricity meter nor the electricity bill mentions the solar panel. So I have no idea whether it's actually working or not. I need someone to advise on whether it's working and, if not, what I need to do to make it work.

...face, call, video call , chat) . The sole purpose is that sometimes we suddenly like someone in a subway, or Street, or market but we fear to interact or start a conversation. But this application will allow other users near you to see if u r intrested to interact with them . And can successfully reduce the effort and time for both. The user can set range to which it should allow( eg 10 meter, 50 meter, 100 meter etc.) It can be used mainly if someone is travelling alone in bus and needs accompany or in a train. Or waiting for something in a cafe. So i need a coder who can code this application for me... I won't be able to provide money now but I can provide him shares of this application as a mode of payment. I know this idea will grow unicorn one day. So if a...

...all the functionality needed for this app. Project brief: I have three BLE devices called GMA1, GMA2, GMA3 - all using a HM-10 BLE 4.0 module. There could be more BLE devices in the future and all will have the GMA# naming convention. As soon as the app starts, it needs to scan specifically for these devices and ignore anything else in the vicinity. The app needs to read the RSSI (signal strength) and display this for each GMA device found. This would be similar functionality to the proximity feature of the Bluepixel BLE Scanner app. The RSSI needs to be displayed in a bargraph style graphical meter - If any GMA BLE device is far away or not found then the meter is green. - If any GMA BLE device is 5+ metres away (-90 and above) then the meter is amber - ...

...particles/contaminants will circulate in the space; some being air entrained others moving randomly with no entrainment based on electrical fields. Then particles will need to be shown entering the mechanical return grill going through the duct and some being captured by the filters while the majority go through. The particles/contaminant will then enter a technology; a 2-grid system using a high voltage field and a high frequency field in which the are accelerated and forced to collide. They should be shown sticking together and growing in size and then continue through the mechanical system continuing to grow and either reach a final filter; single pass, in which the enlarged particles are captured or continuing in to space continuing to grow; recirculating pass.

Your task will be to create an arduino code to communicate between ESP32 and STC3115IJT. The arduino code must print voltage, current and battery status to the serial monitor.

We have a Jmeter script (attached) in to scale test our website. In the script the users all come on and complete actions at the same time, which isn't realistic. Instead of the 10s wait time between actions we would like it to be a random time between 5s and 15s. The finished product will be the same meter script but with the random wait time between actions rather than 10s every time. Thanks, Rob

Hi I'm looking for someone wh...looking for someone who has Raspberi pi (preferably number but doesn't matter, you'll help me adapt it later) at home and is connected to his network. Someone to implement: 1. take a voltage data from a specific GPIO (you can let me know what exactly you chose) 2. transmit the data (voltage) continously via LSL. 3. Check it with Labrecorder (on a different PC) Preferable people with two raspberi pi so they can check the LSL they wrote is working well in time. (should not be a difference in the time domain if both devices get the same voltage spikes at the same time - same data to both, but possible to make readings with different freq.) The freq. should be higher or equal to 512Hz.
