The Assemble instructions on the nullbits website are very good.Īlso if u feel its too much u can buy this keypad it has backlighting and later down the road if you like desolder the switches and solder ones to your liking.

Also if u do go through with it take your time and make sure your doing things correctly. You can buy soldering kit projects on amazon for as little as $7 to practice. A fine solder tip for those small areas u have to solder such as the LED : MythGeek 19 Keys Numeric Keypad, Retractable USB Cord Financial Accounting Number Keyboard with 19 Keys for Mac Windows XP Laptop Desktop PC. Its difficult enough to desolder things without proper tools so I highly suggest you practice and have good equipment such as a soldering iron, good solder wire and Flux and don't cheap out on a good desoldering pump for when u wana desolder.

You practice soldering or else your gonna have a frustrating time trying to figure out what you did wrong

Honestly moderate difficulty its mostly the soldering you have to worry about.
