It will be exactly the same EXCEPT the components and layout will be different from the original square design. I had a freelancer create the original Arduino but as thing evolved it was never panelized and so I need this to be combined with another smaller design so it can be quoted by the manufacture... There is also another type of Arduino design that needs to be made into a new unique design just as the first. Arduino is Open source and the design can be found here -

Need to do a arduino project on propeller based pendulum.

The device is an ion exchanger. It is therefore used to extract ions from media, in this case water. This can be ensured, as long as the device has “space” for the ions. This unit is reprocessed with acids and alkalis after it arrives at the factory. This process lasts from several days to several months, so all materials worked with should be fully resistant to the corrosive and abrasive effects of said media. The device already exists and is now to be extended with useful features for the plant and customers. These various sub-items are assigned as one package, various packages, or separately, depending on competency. The developments of the sensor technology, as well as the processing of the electrical signals resulting from this, are the priority tasks. For further in...

Your task will be to receice an existing product and improve it. The current one is not integrated with home automation systems. It should be. I dont know if there needs to be an app or if it can be i tegrated in existi g apps where the dimming time and levels/rates can be changed The ergonomics/shape of the current one is not optimal. This one will improve that The function of this one is not optimal. The dimming sometimes jumps a bit. 16 ampere electric throughput must be possible. All mayor country voltages must be possible. Single phase is ok. Build instructions that an untrained person can follow is also required. It should follow all the rules. That goes without saying. What is the process to make it accepted for the market? What certifications needed?

Simple project. I have a sensor producing data every 0.8 - 1 seconds. I want to collect the data on a Raspberry pi 4 that has a SIM card in it. The Raspberry will communicate with a Cloud based database every 3-5 minutes providing dumping the data into the database for the given account and location. The sensor is a Rogowski coil. I will provide more details, but just trying to source assistance first. You must understand how a Rogowski coil works in order to quickly perform this project.

The GUI will be part of a system that we develop. It needs to be developed on Workshop 4 IDE and the final version needs to have: - An intro screen with the a short logo video - 2nd page - HOME PAGE - needs to manage the different functionalities that our system requires. All the commands are sent via serial ports from a raspberry PI zero. - the firmware on the raspberry will give the screen some variables that needs to be shown on the screen and can be also modified from the screen. - The images will be provided and stored on the screen sd card. The app needs to run directly on the screen, it won't be managed from the raspberry CPU.
