A DIY CNC Machine - The DIY Dudes Rift

Ever since my brother was a wee boy he wanted a CNC machine. While I was climbing trees, playing tag, and goofing around, he was tinkering with electronics and salvaging parts from old scanners. In fact, he wrote an instructable on how to build a stepper controller from recycled parts 7 years ago when he was just a kid (side note, that thing got over 300 000 hits!). Needless to say, a CNC machine was his childhood dream. Over the years he made a few attempts, which were impressive given the materials he used and the fact that he was...

WiFi Enabled Thermometer

I've always wanted to learn more about internet connected systems (also known as “the internet of things”). My goal was to create a basic sensor network that could be expanded to a full home automation system. I chose to start with a simple temperature sensor and display. The sensor sits outside, and sends its temperature reading to an internet server over Wi-Fi. The display module connects to this server and displays the temperature. Since our display is internet connected, we can expand it to include other features, including getting a weather forecast for the next 3 days. Both the display...

A Simple Router Table Vacuum Fitting

My father and I recently decided that we wanted a router table. Rather than buying a full unit which would be expensive and take up precious shop space, we decided to build an insert that would mount to a table saw. I won't go into the details of the table build (perhaps in another post), but want to share the vacuum mount I made for the table. In order to accommodate the router, an extension had to be made for the table saw fence (the bit needs to be able to go into a slot in the fence). My father...

3D Printing a Crossbow

It's safe to say that 3D printing has moved past trinkets and toys and onto more interesting things. From large scale objects like cars to functional 3D printed motors, it seems that almost anything can be 3D printed. In order to build these huge or complicated items, one must work around the limitations of 3D printing and make careful design choices. A key shortcoming of 3D printing is the strength of the parts. With this in mind, I pose the question: is it possible to 3D print a powerful full sized crossbow? Yes, in fact, it is. Materials This crossbow...

3D Printed Arrow Fletching Jig

An Archer is only as good as his arrows, and making a good arrow is easier said than done. An important part of arrows is the fletching; it plays a key role in making the arrow fly straight. Installing the fletching can be tricky, which is why fletching jigs were invented. A fletching jig holds the feathers or vanes in the correct position as you attach them to the arrow shaft. There are lots of commercial fletching jigs available, but they can be fairly pricey. They certainly don't cost $1 like my jig did! The Design I wanted this jig...
