The Nokia 3310 Finally Gets A USB-C Upgrade

The Nokia 3310 has a reputation of being one of the most indestructible devices ever crafted by humanity. It’s also woefully out of date and only usable in a handful of countries that still maintain a GSM network. It might not be easy to bring it into the 5G era, but you can at least convert it to work with modern chargers, thanks to [Andrea].

[SGCDerek] whipped up their own solution for USB-C charging.
If you don’t want to buy the parts, you can just DIY the same mod. [SGCDerek] did just that a few years ago. From what it looks like, you likely don’t even need to worry about doing any fancy charger handshaking. The 3310 will happily grab a charge from a low-current 5V supply straight off the USB pins.

You might think this is a messy, complicated mod, but [Andrea] engineered it as a drop-in upgrade. He’s combined a USB-C port with a small plastic adapter that enables it to sit in place of the original phone’s charge port module.  Contact between the port and the rest of the phone is via spring-loaded contacts. The only additional step necessary is popping out the mic from the original charge module and putting it in the new one. You need only a screw driver to disassemble the phone, swap out the parts, and put it all back together.

If you want to upgrade your own handset, [Andrea] is more than happy to provide the parts for a reasonable price of 25 euros. It’s almost worth it just for the laughs—head around to your friend’s house, ask to borrow a charger, and then plug in your USB-C 3310. You’ll blow some minds.

Once upon a time, it was big news that someone hacked a USB-C port into the iPhone. Video after the break.

Capacitive Buttons Control All Life

Projects involving Conway’s Game of Life and utilizing a Nokia 3310 screen are quite popular with electronics hobbyists. [Droky] put these two together and went one step further by adding capacitive sensors to control the Game of Life. His work is a great example of how to use the Atmel QTouch capacitive sensor (QT100a datasheet). This chip does the heavy lifting that we’ve seen in other touch sensitive solutions. It operates from 2V-5.5V, requires only three capacitors and a resistor, has a one pin active high output, and sells for around $1 in low quantities. One thing [Droky] overlooked in his board layout is the ground pad on the bottom of the WSON6 chip. He was able to make it work by masking the trace that runs under the chip but you will want to alter the layout in your own designs.

If you’ve used the QT100a before we’d like to hear about your experience, and find out if button debounce handling is necessary with this chip. Let us know in the comments. You can see a video of it in action after the break.
