Wifi-Controlled Christmas Ornaments!

Posted on by

Trimming one’s Christmas tree can be an enjoyable tradition year after year, but every once in a while some variation on  the established order can be just as fun. Seeking some new ornaments to and desiring to flex his skills, Instrucables user [Gosse Adema] created a LED-illuminated, phone-controlled, deltrahedron Christmas tree ornaments.

Wemos DI Mini Pros are the brains of these little guys, WS2182b RGB LED strips — being the superb go-to’s that they are — light the ornament, and a 5 V power supply keep them lit. [Adema] used the Wemos specifically to create a web server unique to …read more

3D Printed Mini-Printer Enables Obsession With Lists

Posted on by

When going about a busy day, a hard copy listing all your tasks helps if you aren’t inclined to pull up a notepad — or whatever app you use — on your phone each time; doubly so if you want to pin it up in one place to refer to. Besides, using a full sheet of paper for a few items is impractical — and wasteful. To that end, [Jed Hodson] has concocted a mini printer for all your listing needs.

[Hodson] designed and 3D printed the case, making the files available for download and instructions on how to assemble …read more

Smartphone Case For The Retro Gamer

Posted on by

A well-designed phone case will protect your phone from everyday bumps with only as much style flair as you’d like. While protection is usually the only real function of a case, some designs — like [Gabbelago]’s Emucase — add specific utility that you might not have known you needed.

Contrary to most cases, the Emucase fits over your phone’s screen, and the resulting facelift emulates the appearance of a Game Boy for easier — you guessed it — Game Boy emulation play on your smartphone.

Cannibalizing a USB SNES gamepad for its buttons and rubber contact pads, Gabbelago then threaded …read more

Fully 3D Printed Snow Blower

Posted on by

For anyone living in cooler climates, the annual onslaught of snow means many hours shoveling driveways and sidewalks. After a light snow, shoveling might seem a waste of time, while a snow blower would be overkill. If only there were a happy middle ground that required minimal effort; perhaps an RC snow groomer with a 3D printed snow blower would work.

We featured an earlier version of this project last year. This year’s model features a slipper clutch — combined with a differential from a heavy RC truck — to forestall damage to the attachment if you happen to hit …read more

Bluetooth Speaker With Neopixel Visual Display!

Posted on by

Finding a product that is everything you want isn’t always possible. Making your own that checks off all those boxes can be. [Peter Clough] took the latter route and built a small Bluetooth speaker with an LED visualization display that he calls Magic Box.

A beefy 20W, 4Ohm speaker was screwed to the lid of a wooden box converted to the purpose. [Clough] cut a clear plastic sheet to the dimensions of the box, notching it 2cm from the edge to glue what would become the sound reactive neopixel strip into place — made possible by an electret microphone amplifier. …read more

Make Mulled Wine With A Processor Heatsink!

Posted on by

Now, over the holiday season there seems to be a predilection towards making merry and bright. As many an engineer and otherwise are sure to note, fine alcohols will facilitate this process. One such warm holiday beverage is mulled wine; there are many traditions on how to make it, but a singular approach to preparing the beverage would be to re-purpose an old PC and a CPU liquid cooling unit into a mulled wine heating station.

Four years ago, [Adam] found himself staring at a pile of mostly obsolete PCs in his IT office and pondering how they could be …read more

A Menorah For The 21st Century

Posted on by

For those new and experienced, this time of year is a great chance for enterprising makers to apply their skills to create unique gifts and decorations for family and friends. [Mike Diamond] of What I Made Today built a phone controlled, light-up menorah. It’s a charming way to display some home automation know-how during the holidays.

Expanding on his previous project — a pocket-sized menorah — a Raspberry Pi Zero with a WiFi dongle, some LEDs, wire, and tea lights suffice for the materials, while setting-up Blynk on the Raspberry Pi and a phone to control the lights ties it …read more

Massive Pixel Display Holiday Decoration

Posted on by

Decorating for the holidays is serious business! Finding themselves surrounded by neighbours who go big, redditor [wolfdoom] decided that this was the year to make a strong showing, and decided to build an oversized pixel LED display.

Demonstrating resourcefulness in their craft, [wolfdoom] found an old fluorescent light grid pattern to prevent bleed from one pixel to the next. Reusing this grid saves many hours of precision-cutting MDF — to be substituted with many hours of cutting the plastic with decidedly more room for error. Attaching the resulting grid to a sheet of plywood, and 576(!) drilled holes later, the …read more

A DIY Net Gun To Catch Whatever You Want

Posted on by

Suspicious drones hovering about your property? Burglars or other ne’er-do-well test subjects giving you trouble? Need to catch a dog that keeps meandering through your workshop? [William Osman] suggests you build yourself a pneumatic net gun that can shoot 20-30 feet to catch them all.

The net gun is built largely out of PVC pipe; the air tank — filled via a tire valve — uses adapter fittings to shrink it down to a 1″ sprinkler valve, with an air gun to act as a trigger. The net launcher is made of four lengths of pipe bent with the use …read more
