Tumble Polisher Smooths Parts With Ease | Hackaday
When you’re 3D printing parts, it’s easy to create pieces with all manner of complex geometry. However, you’re often stuck dealing with unsightly layer lines and other surface imperfections. [reitter_m] chooses to get around this through the use of a tumble polisher of his own design.

The polisher uses a drum made out of a glass jar sourced from IKEA. A 3D printed gear is printed to size, and then fitted around the outside. This allows the drum to be turned by a motor fitted into the base of a 3D printed cradle. A simple gear motor is used to spin the drum nice and slowly, powered by a 12 V, 500 mA supply.

Austere Engineering Hack Chat | Hackaday
For most of us, building whatever it is that needs building is something that occurs in relative comfort and abundance. Sure, there are cold workshops and understocked parts bins to deal with, but by and large, we’re all working in more or less controlled environments where we can easily get to the tools and materials we need to complete the job.

But not all engineering is done under such controlled conditions. Field operations often occur miles from civilization, and if whatever you need is not in the back of the truck, it might as well not exist. At times like this, the pressure is on to adapt, improvise, and overcome to get the job done, especially if people’s lives and well-being are at stake.

Teardown: BilBot Bluetooth Robot | Hackaday
Historically, the subject of our January teardown has been a piece of high-tech holiday lighting from the clearance rack; after all, they can usually be picked up for pocket change once the trucks full of Valentine’s Day merchandise start pulling up around the back of your local Big Box retailer. But this year, we’ve got something a little different.

Today we’re looking at the BilBot Bluetooth robot, which over the holidays was being sold at Five Below for (you guessed it) just $5 USD. These were clearly something the company hoped to sell a lot of, with stacks of the little two-wheeled bots in your choice of white and yellow livery right by the front door. With wireless control from your iOS or Android device, and intriguing features like voice command, I’d be willing to bet they managed to move quite a few of these at such a low price.

Inputs Of Interest: Tongues For Technology | Hackaday
Welcome to the first installment of Inputs of Interest. In this column, we’re going to take a look at various input devices and methods, discuss their merits, give their downsides a rundown, and pontificate about the possibilities they present for hackers. I’ll leave it open to the possibility of spotlighting one particular device (because I already have one in mind), but most often the column will focus on input concepts.

Unless you’ve recently bitten it, burned it, or had it pierced, you probably don’t think much about your tongue. But the tongue is a strong, multi-muscled organ that rarely gets tired. It’s connected to the brain by a cranial nerve, and usually remains undamaged in people who are paralyzed from the neck down. This makes it a viable input-driving option for almost everyone, regardless of ability. And yet, tongues and mouths in general seem to be under-utilized as input appendages.

Motorized Inline Skates Run On Makita Power | Hackaday
Inline skates can be fun, but like most wheeled contraptions, they’re even better when motorized. With just such a goal in mind, [The Real Life Guys] decided to whip up a set of powered skates, running on Makita power!

To get power to the ground, the third wheel on each skate is modified to have a sprocket attached. A Makita drill is then fitted to the skate, transferring power to the wheel through a 90-degree gearbox and a chain drive. The drill is controlled by removing the trigger from the shell and hooking it up with an extended cable.

A Deep Dive Into Low Power WiFi Microcontrollers | Hackaday
The Internet of Things is eating everything alive, and the world wants to know: how do you make a small, battery-powered, WiFi-enabled microcontroller device? This is a surprisingly difficult problem. WiFi is not optimized for low-power operations. It’s power-hungry, and there’s a lot of overhead. That said, there are microcontrollers out there with WiFi capability, but how do they hold up to running off of a battery for days, or weeks? That’s what [TvE] is exploring in a fantastic multi-part series of posts delving into low-power WiFi microcontrollers.
