Hi, The following is to be produced to act as a proof of concept for a larger project. I require the following: - I am looking to create a system whereby small e-ink displays (approx. 10-12 inch) are all connected via mesh network and powered by battery. They are to be able to receive data from a "master terminal" that will be a PC and mains powered and display whatever is requested from them. So basically the master PC will send a message out to say Sign 1 to display "1", sign 2 to display "2", sign 3 to show a logo etc etc. The three signs would then carry out the requests. The only data required to go back to the master is any fault reports and battery status. The idea behind mesh network is to ensure that if any one sign fails the data can still get to the other signs etc. Each sign will be upto 20 mtrs apart and eventually there will be upto 10 signs per system and so cabling isn't an option as well as for other reasons. The entire system has to be battery powered with no option for solar or mains power etc which is why we have chosen e-paper which hardly consumes any power when iit is not updating. We are more than happy for the entire system to be off between updates which should be settable for between every minute and every 10 minutes in the first instance. Our initial research has led us to the ESP32 chip which is ideal for LIPO battery circuits and power consumption as the board basically shuts down on demand but can still be woken up via a time for updates. That coupled alongside the fact that the system ill be mesh networked means that the "on" time will also be very short due to the fact it doesn't have to go through a router or DHCP etc Budget has been set for the code development piece only at this point but is likely to be reassessed as and when we progress.

Hello thanks for making this job application available. We are hardware Research & Development team of 4 from Croatia. Over the last 6 years, we have worked on over 30 projects that include professional R&D of hardware. In our team, we have covered all positions & know-how needed in order to get product from the idea stage to the manufacturing stage. We are, at this very moment, working on our internal eInk project where we have reverse-engineered a cheap eInk display and made a controller for it using the ESP32. Currently, we are designing a single board with all needed electronics onboard(power supply, controller, logic). We are very open and looking forward to an opportunity to discuss this project with you in more details. Best regards David Zovko
