    It's a wonderful calculator kit, but I wanted to make my own calculation program, so I modified this calculator kit. 1. Changed the CPU from IAP15W413AS to PIC18LF2685. 2. Add ICSP connector and reset circuit. 3. Add LCD brightness volume and adjusting hole. 4. Add holes for battery replacement 5. Changed D1 to Schottky barrier diode. 6. Programming will be created. I'm looking forward to it.

    Semplice da realizzare con interessanti funzioni utili per l'hobbista elettronico. Se poi si vuole è possibile programmarla per fargli fare cose differenti e più evolute. Divertente e utile.

    I ordered one as a sample to test, if I could build this with our youth group. I think this is a nice project and I'll try to check with customs what it will cost to buy these as a bulk order. However, there is a written Manual, but that is out of date. There is a written link to an online manual on that small paper, you should use this to build it. Unfortunately the manufacturer decided to pack smaller rubber feet and these are now to flat. As a result the screws scrape on your desk. You need to

    Easy to fit, all parts fit well. It works well, it's a nice device, it's handy for easy scaling.

    Works vell with 5V 500mA power suply (no battery need). Conversion HEX-Dec works well, DC current for LED and color rings too. Calculator works with 7 digits only, but no problem. Finaly, everything works good. Thanks
