12-axis sensor adds auto screen orientation to this older tablet PC

screen-orientation-sensors

[Mal'oo] has one of those laptop computers whose screen swivels to turn it into a tablet. But the thing is a few years old and didn’t come with an orientation sensor that changes the screen between landscape and desktop, but also knows which side is up. His solution was to add a 12-axis sensor via the mini PCI express header.

The hardware comes in two pieces. The first is a mini-PCIe card to USB interface. This is handy if you want to add a Bluetooth dongle permanently to your computer. But he’s got other things in mind for it. After hacking the BIOS (which for some reason limits what you can plug into this slot) he moved onto the second part which is a USB 12-axis sensor. This picture shows the wires before they were soldered to the USB card. [Mal'oo] couldn’t just plug it in because the sensor wouldn’t have been oriented correctly in relation to the computer. The final product is quite response, as shown in the clip after the jump. [Read more...]

Aspire One 3G hack

[tnkgrl] is back with part three of her Acer Aspire One hacking. This time she’s adding in 3G. You may look at the picture the above and think, “Cake. She just plugged the card in”. No, the Acer doesn’t ship with the mini-PCIe slot or the SIM card holder. First you have to solder a right angle mini-PCIe connector to the board pads and bridge two others to provide power. The SIM holder was another problem. She wasn’t able to find a pin compatible one. The one she installed is mounted to a riser so she could change the wiring order (let her know if you can find the correct part). This mod definitely requires some good soldering skills and she warns that even she managed to destroy a SIM in the process.

The Dell Mini 9 is another netbook that doesn’t have the appropriate connectors soldered on board, but JKK has a work-around. You need a 3G modem that has the SIM card on board. You plug it into the WiFi slot after taping over a few pins and then use a USB WiFi card instead.
