Bulding an RPN Calculator

[pcardoso73]

Hi,
Thank you all for your kind words.

Quote:Also, does that = key work as ENTER now?

Actually the key which will be the ENTER is the big + key. I thought that the ENTER should be large, hence the choice.

Regarding the development, nothing happened this week. Today I received a hot glue gun and a set of metal files. I have ordered the files since the calculator's case doesn't close where the LCD is. Fortunately, it has some slots that can be filed down.

Then I will use hot glue to put everything in its proper place.

But before closing the calculator, I will have another problem to solve:

• the type of battery
• how to connect it
• single or dual power?
• do I use the coin cell that came with the calculator ?
  

The last reminds bullet makes me laugh, because it reminds me when I opened the calculator for the first time. Despite saying that the calculator is dual powered, the solar cell is fake and instead, they put inside a coin cell. :-)

Soon I will post some more photos and details.
Thanks.

Cheers,
Pedro
