Cheap GPS modules

GPS

If you’re making a GPS-enabled project, you may have noticed the commonly available GPS modules are pretty expensive – usually around $50. Here’s one for $8. It’s a U-blox PCI-5S GPS receiver on a PCI Express card. There are test points for serial and USB data, though, so fitting this in your project is a breeze.

Grandfather clock makes a giraffe’s scarf

Here’s a clock project from [Siren Elise Wilhelmsen]. Over the course of 365 days, the clock knits a giant, 2-meter tube of yarn that should be the perfect start for a half-dozen pairs of socks. No video for this, but if you find one, post a comment.

A huge hackerspace for Hotlanta

Atlanta is getting a new hackerspace. It’s called My Inventor Club and they’re starting to move into their space. Judging from [Scott]‘s pictures of the new space it’s huge. We can’t wait for the video tour once they’re done moving in.

Ardino and Windows 8

Windows 8 is… weird… and you can’t install unsigned drivers without a lot of rigamarole. This means installing the Arduino IDE is a pain but [Dany] has a solution. Reboot into “test mode” and you can install unsigned drivers without your computer throwing a hissy fit.

Tweet for welts and bruises

[Zach]‘s boss told him to come up with a Twitter-controlled paintball gun. Why he was asked to build this is beyond us, but the build is still cool. It’s powered by an Arduino and was built in just 12 hours. If only there was a video stream…

Hey guys, need some help here.

Alright, I’ve got a little problem with component sourcing. I’m making a ‘shield’ for the Raspberry Pi. Does anyone know where I can get really long female headers for the GPIO pins so the board will fit over the USB and Ethernet jacks? Here’s the project if you’re curious. I think the female part of the header needs to be 14mm high at least to fit over the USB port.

EDIT: Samtec ESQ-113-33-L-D. Here’s their site. This site is amazing. You can actually… find things. Completely unique experience here. Thank you, [Richard].

No PCIE slot? Just add one

[Leslie] likes his little Samsung N150 Plus netbook. While it packs enough punch for almost everything, it lacks in High Definition video power. That is where a Broadcom Crystal HD mini PCI express card comes in, as these little video decoders are made just for netbooks needing some HD love, but the problem is, his netbook only has one PCI express slot in it, and its occupied by the 802.11N card.

Not being bummed out by this, and not wanting to use a USB dongle device he just ripped open his netbook and added a second pci express connector to the pads on the motherboard. Sourcing the header from mouser, the install seems quick n easy, especially since Samsung was nice enough to have the pad’s tinned already, so just a little flux and a steady hand you’re good to go.

Unfortunately, there are some hidden gotcha’s as the newly installed slot is not “full featured” that both the Broadcom card and the stock wireless N card require, but he had a wireless G card that ran just fine in the newly added slot, so now its time to rock some full screen HD Hulu.

DIY driving controller

It looks like this steering wheel, shifter, and foot pedal were all made from string and garbage. That being said, you can see it works quite well. The setup just pushed keys on the keyboard,  which reminds us of the junky plastic add-ons for the Wii remote. [Thanks Toumal]

Taping PCI express

[Pseudolobster's] company was putting together point-of-sale machines for a retailer. They had surplus computers which really brought the price down but ran into a snag when adding the second monitor. The boxes wouldn’t play nicely with PCIe 16x. His solution was to scotch tape pins 19-82 on the cards, effectively turning them into PCIe 1x… and it worked! No link here but we wanted to share the trick anyway.

USB character display

[Simon Inns] shows how to add a character display to a PC case. We’ve seen him work with these PIC 18F2550 controllers several times before but we like how nicely this piggy-backs the display board seen in green.
