How To Drill A Curved Hole
Next time you’re renovating and need to run some cables around corners in you walls, save yourself some frustration by building [izzy swan]’s corner drilling rig. It’s something akin to a custom tunnel boring machine but on a small scale.
Starting with a piece of steel, [izzy] traced and cut out a 90 degree curve with an attached arm that will allow it to rotate from a central block. He then grabs a random drill bit and attaches it to a flex shaft which is secured to the leading point of the steel curve. To complete the handy setup the …read more
Arduino Sketch: The Next Generation
What was your first Arduino program? Probably an LED blinker — that seems to be the “hello world” of microcontrolllers. You probably moved on to things a little more complicated pretty quickly. At some point, things get harder because the Arduino lacks an operating system.
There are operating systems that will run on the Arduino. They aren’t full-featured like Windows or Linux, but they allow you to run multiple tasks that are both isolated from each other (to some degree) and have a way to cooperate (that is, synchronize, share data and resources, and so on). One such operating system …read more
How to Run a Pagekite Server to Expose Your Raspberry Pi
Last time I showed you how to expose a web service on a Raspberry Pi (or, actually, any kind of device) by using a reverse proxy from Pagekite. On your Pi, you just need a simple Python script. However, it also depends on the Pagekite server, which isn’t always convenient. There are limits to the free service, and you don’t control the entire thing. The good news is twofold: the same Python script you use to set up the client-side can also set up a server. The other good news is the entire thing is open source.
In practical terms, …read more
Here’s the Turbocharged BBQ Grill You’ve Been Waiting For
We’re not actually sure that it’s a good idea at all, but it’s got a heck of a lot of style; [Morgan]’s barbecue grill is turbocharged. Literally.
Keeping with the automotive theme, a serve-motor-driven throttle from a Ford Mustang serves as a (naturally-aspirated) air intake, and a Honda Civic manifold delivers it to the grill. But when he really needs to turn up the heat, a 360 watt fan can force-feed the fire. …read more
