RE: Wireless charging for a HP-25 calculator
Hello!

What a phantastic project. But that must have been a very long weekend. Designing and 3D-printing the box alone would occupy me for much more than a couple of days...
Do you have any intention of getting a small batch of these boards made? If so, I would be very interested!

Thanks
Max

Addition: I just ordered a couple of ready-made wireless chargers from Aliexpress (shortened link: shorturl.at/puPQ7 - if that link doesn't work after some time just search for "wireless charger receiver" there and sort the list lowest price -> highest price) at a whopping 2 Euros a piece. It is small enough to fit inside an empty - or 3D printed - Woodstock battery box. Accoring to the listing this can be directly connected to a LiPo battery. In two weeks or so I will know more.
