I want to make a very simple battery alarm app for all version of windows - windows 11,10,8,7,xp & all types of Linux & Apple Mac also. It will issue a warning when battery will reach levels as told by user. User can specify up to 20 levels. Warning can be text , audio or video message or all 3. This app will be a adware. If user does not buys the app he will have to see Ads whenever a alarm will generate. App will download Ads from a web server and show below alarm notification. It will be great if the same app will run in cell phone also.

...electricity markets. In addition to deciding which market, or combination of markets, to participate in, they also need to decide what quantities of energy (and when) to buy and sell. This is becoming increasingly difficult given price volatility in wholesale electricity markets (which is in part influenced by the build out of variable renewable generation assets). In this project, I will consider a hypothetical battery which will operate solely in the day ahead market (i.e. we focus on a particular optimisation problem in the overall domain). Then, following similar or alternative approaches to those outlined in the reference material below, we have to derive both “perfect foresight” and “imperfect foresight” estimates of the storage value o...

I need an Electrical Engineer to produce report for Solar Farm. The project size is on 1 acre land. The target user to support is 150. The average usage is 10/kWh daily per person. The average sunlight hours is 5 hours. The target autonomy of the system is 2 days. I need the Engineer to produce report in words from which include source to supply (online link) the material needed to build the solar farm like model, unit & price for solar panels, Inverters, battery etc.

I need virtual assistance help from time to time however not yet on regular basis. In addition, I wanted to ask this. Can you help me with the following: A. Make a list of all “motorcycle battery manufacturers” in Pakistan. B. Examples of names that might come up: AGS, Exide, Osaka, Phoenix, Homage etc C. Separate types of motorcycle battery each local manufacturer sells, example: lead acid battery, lithium ion, copper, nickel, cobalt, dry etc. D. Incase selling prices are available, please mention. (I think prices will not be easy to find because rates keep changing. So don’t focus much on this point. Incase readily available on manufacturers website that is okay. Otherwise no need)

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.

...operates: - Pressure switch consists of the pressure plate and a tri-colour LED. - Switch connects to a mobile app via Wi-Fi SSID and Password (both are known) - The App displays the pressure switch’s ID name, IP address, MAC address, battery level, etc - When the pressure switch is activated (tapped) the LED changes colour and it sends data to the app I have built a simple sketch, via the Arduino IDE ESP32 WiFi examples, to connect to the pressure switch and successfully print the connection status and IP address to the serial monitor. Scope of this project: I need a simple ESP32 sketch that connects to the pressure switch/mobile app via WiFi and to outputs to the serial monitor any data that is being sent/received like. From this I can hopefully reverse engineer...

...magnets when rotating (at a 29” tire at 10mph it will rotate 116 RPMs) to give the coil a gap to allow them to obtain maximum power output. As the coils obtain this power output it will be in an AC mode. It must be converted to a DC mode, then cycled into a PCB board to convert it to either charge a 48V lithium Ion battery (54.6V input) or 52V battery (58.4V input) with max AMP input between 2 AMPS to 5AMPS. This will have 2 mechanichal swtich to allow rider to pick which battery to charge while it is being ridden, so it will have a constant charge. The rotor on Flat Plat will be encompassed by a “U” shape alloy shell mounted to the frame of the EV and surrounding the Flat plat or rotor to maximize its power output. It can also be used on any pulle...

GUI design PID control Battery and charging Wifi and Bluetooth model

A power supply board design required. Board will have an AC input which will be able to work on 115V and 230V mains voltages. Board will have 6 different isolated 24V DC outputs, these outputs will be able to supply 1A of current typically and 1.2A on burst condition. Also there will be 5V 3A and 3.3V 1A non-isolated outputs. There will be 2x 12V Lead-Acid battery connection for backup the mains input. Power supply will be controlled with an integrated microcontroller and will support security functions. Design will be performed with avoiding obsolete parts and will utilise SMD technology. In the first stage, detailed system plan needed prior to elecrical design.

I need to read battery voltage and current directly because in normal android app programming, the battery voltage always stuck on a number for a long time while current is changing all the time. This example is not accepted because current is always change, but the voltage is stuck on a number, each sample is in one second: Voltage(mV),Current(µA) 3680,220947 3680,189514 3680,160522 3680,161743 3680,185547 3680,160522 3680,139770 3680,148010 3680,434875 3680,275879 3680,383606 3680,1166993 3680,624084 3680,216369 3680,208435 3680,340576 3680,516662 3680,528870 3680,194702 3680,208435 3680,691223 3680,322876 3680,769653 It's very hard to describe what I really need.

We are in need of a 3D image to provide to our manufacturer for a new toy product. This should be a very simple project for an experienced 3D artist! We are duplicating the look of a cellular tower that will have a small battery and light. We have attached a sample image that should make things easy to duplicate into 3D and we are available to answer questions to make for an easier job for the artist! If you refer to the attached sample image, this shows the object we are looking to create into a plastic toy. Our design will only be approximately 5-6 inches in height, and 3-4 inches in width at the widest part. The toy will be a simpler version of the tower in the image, and we will only need one of the round drum/dish objects that are shown on the tower. For the toy,...
