In our Dev Phone 1 enjoyment last week, we somehow overlooked phoneWreck’s teardown of the T-Mobile G1. The complex slider system is definitely worth looking out. one of the major oddities they point out is the inclusion of two vibration motors. One is mounted next to the SIM on the mainboard. While the other is mounted in the frame next to the earpiece. We question what was gained/solved by utilizing two. The phone likewise includes a digital compass module. We’d like a a lot more in-depth explanation of exactly how the Xilinx CPLD is used. From this post in 2006, it seems HTC utilizes them to produce custom-made clock signals as well as changing off gadgets for power management.
