I'm looking to build a charging device that uses the ESP32 micro-controller powered by a Li-ion (for example battery for a FireBeetle ESP32 battery port) or Li-Po battery which will be charged by a solar panel. At the same time (while charging) the ESP32 will be still working for the purposes it has been installed for (it will be working for 10 hours, between 09:00 and 19:00, so actually working only in the charging hours). Of course it should have protection when fully charged, to stop charging, etc etc. Please, only for hardware designers who have already made something like that. The other offers will be dismissed.

We have a schematic for a power supply design. We need the PCB designed in Eagle 7.5. BOM with package data will be shared. • Design will have to consider EMI/EMC aspect for certification. • There are approx. 48-50 unique components and about 115 total. • PCB is double-layered. Size isn’t a criterion, just not too large - 150mm x 150mm (f.e.). • You can use generic libraries and open-source libraries. Please check the attached pdf for more details.

Hello everyone! I'm looking for an experienced professional to help me with a mechatronic design.

Need an electrical designer to help document power board scopes with schematics for fit outs, More details will be shared over a chat

However, instead of physically designing the board, the designer will create a digital representation of the PCB using specialized software. This digital file will contain all of the information necessary for the manufacturer to fabricate the physical board. During the design process, the designer must consider factors such as signal integrity, power distribution, thermal management, and manufacturability. These factors can have a significant impact on the performance and reliability of the final product. Once the digital PCB design is complete, the designer will generate manufacturing files that provide the necessary information for the manufacturer to produce the board. This includes information on the size and shape of the board, the location of components, and the routing of electric...

I like to create counter timer using Raspberry PI HDMI display port also with remote monitor capable. We use the timers for keep track of mixing product with several ingredients. Each ingredient has own define time. The Raspberry PI will display on TV screen. It will display past ingredient if there are any otherwise will be blank. The center will display the current timer and next coming up timers will also display. There are several buttons for enter time, ingredient name, start and stop. I only shown 4 on the pdf, may be needed few more.
