Soda Can Lamp Pinpoints Your Interests

Posted on by

We’ve said it a million times before: 3D printing will expand your horizons. The more you print, the more you think about things you could print and new ways to use printing in the process of building projects. [AHNT] knows all about this phenomenon, because he thought of a way to use soda cans as canvases for customizable pixel art lamp shades.

[AHNT] designed a printable sleeve that fits perfectly over 250mL cans. It provides a sturdy grid for poking tiny holes with a medical needle, and can be reused indefinitely with any pattern imaginable. He created two different printable …read more

Review: LinkSprite Mini CNC

Posted on by

It’s a great time to be a hobbyist. No matter how you feel about the Arduino/Raspberry Pi effect, the influx of general enthusiasm and demand it has created translates to better availability of components, a broader community, and loads of freely available knowledge. When people have access to knowledge and ideas, great things can happen. Tools that were once restricted to industrial use become open source, and the price of entry-level versions goes into a nosedive.

As we’ve seen over the last several years, the price of cheap 3D printers keeps falling while the bar of quality keeps rising. It’s …read more

An Enchanted Rose For A Beauty

Posted on by

Being a maker opens up so many doors in terms of ways to romance one’s partner through passion projects. If their passion is Disney films, then you may handily make them the enchanted rose from Beauty and the Beast for their birthday. Easy-peasy.

In addition to the love and care that went into this build, redditor [Vonblackhawk2811] has included a set of LEDs, salvaged from cheap flashlights and electronic candles, which are controlled by four toggle switches and offer multiple lighting selections — candlelight, soft white, colour cycling, and bright white — to appropriately set the mood. As if that …read more

Blowing Out A Candle Flicker LED: The Death Of Flame

Posted on by

One day there will be no more need for flames. [slider2732] has put yet another nail in the coffin of this most ancient of all technology by making a candle that uses a flicker LED that you blow out. A little more miniaturization and we’ll have them fully integrated into the size of birthday cake candles (Hint hint, hackers!).

You may have seen these candle flicker LEDs.  They have a small chip inside them that modulates the LED’s light to flicker like a candle. We’ve even reported on what [Cpldcpu] found when he reverse engineered them first here and then  …read more

AVR vs PIC, Round 223: Fight!

Posted on by

Get ready to rumble! [Thierry] made the exact same Hello-World-esque project with two microcontrollers (that are now technically produced by the same firm!) to see how the experience went.

It’s not just an LED-blinker, though. He added in a light-detection function so that it only switches on at night. It uses the Forest Mims trick of reverse-biasing the LED and waiting for it to discharge its internal capacitance. The point is, however, that it gives the chip something to do instead of simply sleeping.

Although he’s an AVR user by habit, [Thierry] finds in favor of the PIC because it’s …read more
