USB hubs are everywhere, but 31 port USB hubs just don’t exist, at least not at your local electronics store. Today’s project shows you how to build your own 31 port USB hub with some off the shelf parts. The project write-up is mixed in with a little USB theory.

This project goes through the very basics of making a USB device using the PIC. The PIC series 18F4550 is a great low-power USB enabled device and this tutorial demonstrates that. Hardware schematics and PIC software is included in the project write-up.

USB has come to the forefront of importance and so knowing how to build firmware to interface properly is important. This hack brings to the ATtiny USB capability and while only USB 1.1, it still opens up a world of opportunity. Check the project write-up for source code and hardware schematics.

This little project shows how to take a semi-broken GPS unit and create a new hardware interface to connect with your laptop. The software and hardware (PCB) schematic is provided for you.

This project is another on the cheap wifi-booster. It uses a similar principle of a metallic parabola around the wifi antenna. I questions the quality of IKEA products for this use, but that’s for you guys to decide.

This is a very simple project that shows you how to build a usb memory stick within the casing of a “sawed off usb cable.” No real engineering at work here, just careful disassembly & re-assembly, but it’s impressive!

StickDuino is a completely open source custom USB stick for an Arduino. If you’ve ever wanted to learn how to interface Arduino to USB or Build a PCB for your Arduino, this is a great place to start.

USB WiFi connections have been around for a few years now and their popularity is ever-growing. A popular mod is to attach your own antenna to the device. This project write-up takes you through that process and makes a few good suggestions.

In what is probably a fairly obvious and easy thing to do with Xbee, we have the arduino wireless programmer. This is a pretty cool idea because it clears up the mess of wires around your project and is very simple integrated into your project.

This project uses the NTP protocol for requesting a timestamp in order to keep the clock synchronized with the internet. It is essentially a tcp/ip client that has been beefed up to do some cool stuff. An AVR micro is used for all the processing. All schematics, software & references are there.
