Turning a plush Dalek into a WiFi enabled robot

You can now “EX-TER-MIN-ATE!” with one finger since this plush Dalek from Doctor Who has been turned into a wireless robot. The build started out with the toy whose only trick was to spout quotes from the popular science fiction television series. [Madox] took it apart to see how it worked, then added some of his own goodies to make it better.

We just looked in on a project from this guy on Tuesday. It was a light painting wand that used the TP-Link TL-WR703N wireless router. This uses the same tiny hardware as the controller. Since it’s a WiFi router it’s quite simple to serve up a control interface on any browser. To make it all work [Madox] designed and printed a new base plate. This provides brackets on which the two servo motors can  be mounted. It also gives him a place to anchor the driver board and the router itself. The original voice hardware is still there, driven by a connection to the router hardware. See the final product in the clip after the jump.

LED wand brings ergonomics to light painting

Quit struggling with hastily patched together electronics for your light painting images. Follow [Madox's] example and build a light painting wand designed with your hand in mind.

You wield it much like a sword, but the only damage it does is to the long-exposure camera pointed its way. The RGB LED strip is controlled by the guts of a tiny little wireless router, a TP-Link TL-WR703N. This lets [Madox] connect using an Android device to upload different images. It also lets you tweak the settings like adjusting the timing between columns to match your exposure settings. The custom handle design provides a home and mounting plan for everything involved. It was 3D printed at the Sydney Hackerspace.

This isn’t the first light painting device running Linux. We’ve actually seen the Raspberry Pi used in much the same way but that final project involved using an entire recumbent tricycle to move the colored lights.

I/O extender board and case for a cheap WiFi router

This 3d printed case houses the already small [TP-Link TL-WR703N] but also makes room for a custom expansion board. The expansion board is designed to make the device more hacker friendly, and who doesn’t need a nice case to hold it?

Since the router board already has a USB port (intended for use with USB 3G modems) the add-on acts as a USB hub. The stock USB connector is replaced by a pin header which mates with a DIL socket on the underside of the expansion board. Through the use of an FTDI chip the expander offers three USB ports and a 2×10 pin header to break out the GPIO pins from the router’s processor. Only two USB ports are visible in the image above. That’s because the third is recessed, and an opening has not been added to the enclosure. This struck us as odd until we read that the port is meant to be used with a low-profile thumb drive, essentially adding internal storage for the device.
