DIY Illuminator for UV Fluorescence Photography

Posted on July 24, 2017 by Fernando Gomes

The image shown is the mineral Hackmanite, which fluoresces under ultraviolet lighting. However, not all UV is created equal, and that makes a difference if you’re into UV imaging. The image for this article is from [David Prutchi] and shows the striking results of using different wavelengths of UV. [David] goes into detail on how to make your own DIY Long, Medium, and Short-wave UV Illuminator complete with part numbers and wiring diagram. The device isn’t particularly complicated; the real work was determining the exact part numbers and models of lamp, filters, and ballasts required to get the correct results. …read more

Hackaday Prize Entry: DIY LCD based SLA 3D Printer

Posted on June 7, 2017 by Fernando Gomes

Resin-based SLA 3D printers are seen more and more nowadays but remain relatively uncommon. This Low Cost, Open Source, LCD based SLA 3D Printer design by [Dylan Reynolds] is a concept that aims to make DIY SLA 3D printing more accessible. The idea is to use hardware and manufacturing methods that are more readily available to hobbyists to create a reliable and consistent DIY platform.

[Dylan]’s goal isn’t really to compete with any of the hobbyist or prosumer options on the market; it’s more a test bed for himself and others, to show that a low-cost design that takes full …read more

Posted on March 13, 2017 by Fernando Gomes

There’s no fancy screen. Instead, the watch gets by with a ring of NeoPixels for all its notification needs. But notification is what it does right. It tells [Dominic] when he’s got an incoming call of course, but also has different flashing color modes for SMS, Snapchat, and e-mail. Oh yeah, and it tells time and …read more

Extracting Sounds With Acid And UV

Posted on December 28, 2016 by Fernando Gomes

Toaplan was a Japanese video game developer in the 80s and early 90s, most famous for Zero Wing, the source of the ancient ‘All Your Base’ meme. Memeology has come a long way since the Something Awful forums and a pre-Google Internet, but MAME hasn’t. Despite the completionist nature of MAME aficionados, there are still four Toaplan games with no sound in the current version of MAME.

The sound files for these games is something of a holy grail for connoisseurs of old arcade games, and efforts to extract these sounds have been fruitless for three decades. Now, finally, these …read more
