I cannot explain my obsession with the Nokia 3310. This iconic device definitely marked my boyhood, and I loved messing around with it. After about 4 years, it’s time to revisit and upgrade my old project – and what better excuse to do it than making a conference badge?
I’m happy to announce that I won the HackADay trinket contest!!

Well, today I started testing the analog input circuitry. As you can see, I’m soldering wires directly from resistors to the connector. The casual observer may see this as being too lazy to route a proper connector on the PCB, but it’s really a very sophisticated way to relieve stress on the connector! :P
I also had to add a bodge flyback diode to the buzzer, as I forgot to include one… That’s the second error on the PCB: the other one is taking for granted that I could put two green LEDs in series. I’m too used to modern, super efficient LEDs, but since I’m reusing the original Nokia 12 years old LEDs, they need a bit more current and seem to have an higher forward voltage than the ones I use everyday.

Designing a replacement PCB for the 3310 mainboard requires quite a bit of effort. The first thing I did was to remove all the components from a broken phone, to get a nice scan of the board:

PGAs are quite common, but I don’t have one in my parts bin and I was curious about an idea I had for a while…

A long time ago, (I felt like) I was the coolest kid on the block, with my heavily modified Nokia 3310. A thriving community existed with the purpose of reverse engineering Nokia DCT3 phone firmwares, creating from the simplest mods like changing a few bitmaps to writing a full alternative open source firmware, aka Project MADos. Yes, I was “cooking ROMs” before it was cool.
