ESP8266 Monitor Keeps an Eye on OctoPrint

At this point, you’ve almost certainly heard of OctoPrint. The web-based control interface for 3D printers is especially popular for those who’s primary computers run on an operating system that has a penchant for occasionally imploding. Even if you aren’t laboring under that common software handicap, OctoPrint offers a wide away of compelling features. Perhaps chief among them the ability to monitor your printer over the network, and if you insist, over the Internet. But while OctoPrint provides the server side for getting your printer on the net, you’re on your own for the client.

Rather than using a web …read more

Gorgeous Omnidirectional 3D Printed Speaker

With all due respect to the hackers and makers out there that provide us with all these awesome projects to salivate over, a good deal of them tend to prioritize functionality over aesthetics. Which isn’t a bad thing necessarily, and arguably better than the alternative. But for many people there’s a certain connotation around DIY, an impression that the final product is often a little rough around the edges. It’s usually cheaper, maybe even objectively better, but rarely more attractive.

Which makes builds like this absolutely beautiful 3D printed Bluetooth speaker by [Ahmsville] especially impressive. Not only did he engineer …read more

Cheap FPV Goggles Turned Pocket Sized Display

Thanks to the exploding popularity of First Person View (FPV) RC flying over the last couple of years, the cost of the associated hardware has dropped rapidly. Today you can get entry-level FPV goggles for under $40 USD on various import sites. For the money you’re getting a 5.8 GHz receiver, battery, and an LCD display; even if the components themselves aren’t exactly high end, at that price it’s essentially an impulse buy.

[nomand] didn’t necessarily have a use for a cheap FPV headset, but he did like the idea of having a pocket sized display that he could pass …read more

Pocket-size Pi Zero Desktop features e-paper Display

[Ramin Assadollahi] uses his Raspberry Pi Zero W as a self-contained mobile desktop, connecting to it over VNC from another computer when he wants to hack away at some code or work on a new project. But he often found himself wishing there was some convenient way of displaying pertinent into right on the device, such as what IP address the Pi Zero had pulled. Then he found the 2.13 inch e-Paper HAT for the Pi Zero from Waveshare, and it all clicked into place.

The final device, which he refers to as the StickPi, combines a Pi Zero W, …read more

Building the Perfect Home Router

When a favorite piece of hardware dies, it’s fairly common to experience a bit of dread. The thought that now you’ll have to go through the process of getting a replacement for the device can be very troubling, and is fraught with difficult questions. Is the hardware still available? Has it been made obsolete by something else in the time you’ve had it? But while it can be a hassle, there’s no question you can come out the other side better than you went in. Sometimes it takes the passing of an old piece of gear for you to really …read more

A Detailed Guide for 3D Printing Enclosures

We’ve all have projects that are done, but not complete. They work, but they’re just a few PCBs wired together precariously on our desks. But fear not! A true maker’s blog has gifted us with a detailed step-by-step guide on how to make a project enclosure.

Having purchased an MP Select Mini 3D Printer, there was little to do but find something practical to print. What better than an enclosure for a recently finished Time/Date/Temperature display Arduino based device?

The enclosure in this guide, while quite nice, isn’t the main attraction here. The real feature is the incredibly detailed instructions …read more

Practical Enclosure Design, Optimized for 3D Printing

[3D Hubs] have shared a handy guide on designing practical and 3D printing-friendly enclosures. The guide walks through the design of a two shell, two button remote control enclosure. It allows for a PCB mounted inside, exposes a USB port, and is optimized for 3D printing without painting itself into a corner in the process. [3D Hubs] uses Fusion 360 (free to hobbyists and startups) in their examples, but the design principles are easily implemented with any tool.

One of the tips is to design parts with wall thicknesses that are a multiple of the printer’s nozzle diameter. For example, …read more
