Solar engine (with high output amperage) with off-the-shelf components

$30-250 USD

$30-250 USD

Paid on delivery
I have basic soldering experience and I am looking for the easiest way to build a solar engine to power an ESP-32 device with a power-hungry peripheral. I already have solar panels (6V) and capacitors large enough to power the device for the duration of the process. The missing part is a controller board. Of the dozens of so commercially available, I have found none that is able to deliver that 800mA - 1A I need. I need the list of components (BOM), with code from some supplier (example mouser or digikey or other). Payment in 2 steps: once the project and the components are well defined (70%) and once I successfully put the parts together (30%).

I can modify the Easter Solar Engine circuit to give you up to 1.5A My design would consist of a total of 9 or 10 through hole parts easily constructed on a solderless breadboard for testing. I'll supply you with a schematic and BOM with parts from Digi-Key. Digi-Key has a 1-3 day USPS shipping option for only $4.99, it's great for small orders. I would like a 80/20 milestone payment but full payment MUST be deposited with freelancer. The second milestone must be released 13 working days from the time I provide you with the schematic and BOM. If you claim that the circuit does not work, you must provide supporting documentation such as, pictures of the assembled circuit, scope traces, voltage and current readings reading etc. Regards, Jim
