David Hunt who is a senior embedded Linux software engineer has modded the Raspberry Pi into a $150 phone.
When Raspberry Pi was released, many programmers and hackers got their hands on it and came up with some pretty interesting things they could do with this $40 mini computer. Now David Hunt has practically made this little device into a working smartphone and that too with off the shelf components.
He has also released a complete video proof, showing how this thing works. David has named this PiPhone and here's what Hunt used to make the phone:
- Raspberry Pi Model B – $40
- PiTFT Touchscreen 320×240 – $35
- 2500mAh LiPo battery – $15 SIM900 GSM/GPRS module – $48
- DC-DC boost converter 3.3V – 5V 1A – $10
- Cables, connectors, switch, etc. - $10
Now this phone is not a looker not it has the style but still this project proves that this little computer is capable of doing big things. The PiPhone can make regular calls as demonstrated in the video and interestingly there are no circuits as ‘it’s all made from off the shelf components’ according to David.
