Another OmniBot 2000 Upgrade

There were many toy robots back in the 80s that were — frankly — underwhelming by today’s standards. Back then, any old thing that rolled around with some blinking lights would impress, but the bar is higher today. Then again, some of the basic components won’t really change. You still need wheels, motors, batteries, and all that. But the computers

Powerful Nerf Blaster Aims To Fire 100 Darts Per Second

Nerf has made plenty of fully-automatic blasters over the years, but their toys typically lack punch, precision, and fire rate. [3DprintedLife] set about building a blaster to rectify that last shortcoming, aiming for design that could fire 100 darts per second. The design uses half length darts which tend to fly a little nicer from high-powered blasters. It fires them

3D Printed RC Car is Geared For Speed

You can always go out and buy an RC car off the shelf. However, it’s readily achievable to print your own design that has many of the features of off-the-shelf models, as demonstrated by [Jinan]. [Jinan] set about creating a rear-wheel-drive design with a low center of gravity for good handling. Two large 5.2 Ah batteries slung low in the

A Nifty 3D Printed RC Car

Once upon a time, a remote controlled (RC) car was something you’d buy at Radio Shack or your local hobby store. These days, you can print your own, complete with suspension, right at home, as this project from [Logan57] demonstrates. The design uses standard off-the-shelf hobby-grade components, with a brushed motor and controller for propulsion, and small metal gear servo

Smart Sphere or Magnetic Magic

Sometimes a coworker sees something on your desk, and they have to ask, “Where can I get one of those?” and that has to be one of the greatest compliments to a maker. [Greg Zumwalt] nailed it with his “Marblevator Line Follower.” Roboticists will immediately recognize a black line on a white surface, but this uses hidden mechanics instead of

Remote-Controlled Hypercar Slices Through Air

Almost all entry-level physics courses, and even some well into a degree program, will have the student make some assumptions in order to avoid some complex topics later on. Most commonly this is something to the effect of “ignore the effects of wind resistance” which can make an otherwise simple question in math several orders of magnitude more difficult. At

A LEGO Camera You Just Might Own Yourself

A camera makes for an interesting build for anyone, because it’s an extremely accessible technology that can be made from materials as simple as cardboard. More robust cameras often require significant work, but what if you could make a usable camera from LEGO? It’s a project taken on by [Zung92], who hasn’t simply made a working 35 mm camera from

High-Contrast Images For Hacker Family Harmonics

There’s a new addition to the Adafruit family, and it’s not a microcontroller board as you’d expect – however, we will still find plenty to learn from. On the Adafruit blog, [Phillip Torrone] shares a set of high-contrast images with us; the idea for such images is that they’re more appealing for a child during the first few months of

Model Train Delivers Fresh Coffee

Model trains are good fun, though few of them serve any purpose beyond amusement or authentic railway simulation. [ProjectAir] decided to put his model train to practical use by having it deliver fresh espresso, and faced plenty of difficult challenges along the way. It sounds simple, but the practicalities of the task proved difficult. After all, even a slight wobble

RC Car Gets F1-Style DRS Rear Wing

DRS, or the Drag Reduction System, has become a key part of Formula 1 in the past decade. [Engineering After Hours] decided to implement the same system on an RC car instead. The DRS system was implemented in Formula 1 to increase passing in the series. By moving a flap in the rear wing of the race cars, drag could

CUTTING CABLES CURES TANGLED CORD CHAOS

The Toniebox is a toy that plays stories and songs for kids to listen to. Audio content can be changed by placing different NFC enabled characters that magnetically attach to the top of the toy. It can play audio via its built-in speaker or through a wired headphone connected to the 3.5 mm stereo jack. Using the built in speaker

A Concealed Model Railway Rises To The Occasion

Occasional pieces of furniture serve little purpose other than to fill a space and maybe display a prized ornament or two. Who hasn’t got a relative with one two many small tables or display stands overfilling the available space! If you visit [Peter Waldraff]’s house though, those pieces of furniture may not be what they seem. His display pedestal for
