We’re big fans of surface mount parts. SMD components are cheaper, take less board space, and don’t require drilling; all the coolest new parts are only available in SMD packages.
Smart Tweezers are an advanced multimeter tool specifically designed to test and troubleshoot SMD circuits. It automatically identifies resistors, capacitors, and inductors, and displays the relevant measurements. Advanced Devices sent us a pair of Smart Tweezers to review. We used them while building our last few SMD projects, read about our experience with this tool after the break.

[Pedram] Sent us his USB missile launcher interface project. He happened to have some of the USB missile launchers lying around. having lost their initial draw, he wanted to do something to spice it up. He wrote an interface in python so he could control the launcher via his iPhone. We don’t see how this is any different than controlling them by the computer, but he seems to have put a decent amount of work into it.
[tnkgrl] has concluded her Sony Vaio P by adding GSM support. We covered the switch to XP earlier, but this should work on Vista too. The Vaio P is sold in the US with support for Verizon’s EVDO wireless broadband, but it uses the same hardware as the European model that uses GSM. This is possible because of the the Qualcomm Gobi radio module. To get GSM support, you trick the VZAccess Manager into loading a different firmware than the stock EVDO. The difficult part is that the Vaio P doesn’t come with a SIM card slot, so you’ll have to solder in your own. When you’ve got the computer reassembled, just change VZAccess Manager to use your carrier.
UPDATE: Wired has an article on the Gobi chipset.
[psymansays] needed a panning head for his robotics projects. Already being familiar with the NXP LPC2148 from work, so he wanted to use that to control it. he built his own carousel out of old CDs. The axle of the carousel is a potentiometer. This is what he’s using to determine position. The gear motor was actually cobbled together with bits from a windup toy and an old motor. This may be a bit bulky, but it seems not only functional, but fairly versatile.
