Anyone awake in the early 2000’s knows the familiar shape of those candy bar style mobile phones. In the Shenzhen phone markets we see tons of them. Literally, there are tons of these phone passing through the markets every day. Some are resold while others are disassembled for parts and recycled. This is where all those cheap Nokia 3310/5110 LCD shields come from. It’s great to see so much reuse and recycling.
Having all these cheap LCDs is nice, but most of the interesting and useful parts are wasted. We saw a fantastic opportunity to save a heap of phones from the recycling bin and save people a pocket full of money. We can make a positive impact on the environment if we reuse some of these phones that we are literally tripping over in the streets. Let’s make an Arduino to GSM network bridge for just a few dollars.
