Once in a way we get a hack that makes us wonder – why didn’t we think of that ? [hydronics] tore apart an old LCD monitor and built a fish tank around it. Not sure if the fish notice that they are swimming on the Moon, but it sure makes for an interesting fish tank display.
He starts by ripping apart an old 19″ LCD monitor and built an acrylic fish tank around the display. The backlight of the panel is fixed at the rear side of the fish tank, along with the rest of the electronics from the old monitor.
For an earlier version, he built his own back light, but the second version with the original back light turned out much better. The fish tank pieces were joined together using acrylic glue and left over night to dry, although he still needed to use some silicone to plug leaks.
A Raspberry Pi connected to the monitor’s HDMI input provides the background slide show. [Tony Rieker] helped add bubble animations via some OpenCV code running on the Pi. A live feed of the fish is overlaid on the slide show, adding a level of inception to this tricked up fish tank. The project was recently shown off at the Portland Winter Light Festival.

Whether or not you manged to attend this year’s Burning Man festival we’re dead certain you’ll enjoy reading [Kenneth Finnegan’s] show and tell about the event. This was his first time attending. Aside from his noobish excitement (which is really the only way to approach writing something like this) we’d never know he wasn’t a seasoned veteran. From what he and friend [Marcel] packed along with them, to the attractions he visited, he did Burning Man right!
The two snapped a selfie in the truck on their way to Black Rock City, the community that sprouts up in the Nevada desert every year for Burning Man. Bumper-to-bumper traffic is a surprise in the middle of nowhere, but when you find out that BRC boasted about 68,000 residents this year it’s no wonder. [Kenneth] spends some time talking about the camp they set up, including more than enough solar power, and an amateur radio setup that came in handy in lieu of phone service. This flows into his collection of cool art he came across, most of it massive in scale. There’s even an airport, which is how he was able to snap the aerial photo above.
We think the coolest part of his recollection is the view of ‘city life’. There are night clubs, bowling alleys, radios stations broadcasting live interviews and hosting talk shows, cafés, and much more. Hanging out in the desert at the end of August may not sound like your thing, but reading about [Kenneth’s] odyssey makes us think Burning Man is like Disneyland for Hackers.
Another way to break out dual pin headers
[Uwe] wrote in to share his technique for breaking out dual pin headers. He uses two single pin headers, a piece of protoboard, and a dual row pin socket to make an adapter. This is removable where the other method we saw this week was not.
Web-based slide show hack
Wanting to use an old Android tablet as a digital picture frame, [Gordon] coded up a simple way to use an HTML page to scan your picture directories to feed a rotating background image.
The simplest hot plate
For his chemistry experiments [Charlie] is using a plain old clothes iron for a hot plate. he simply clamps it upside down to the bench. It doesn’t have any stirring abilities, but we already have an old iron in the shop which we use for toner transfer so we’ll have to keep this in mind if we ever need to heat chemicals (might be a good way to warm etchant).
A charging VU meter
This Cambrionix series8 universal charger has columns of LEDs that are animated when a device is charging. [Steve Tyson] works for the company and has had some fun messing with the firmware. He’s showing off the display as a VU meter.
Game Boy knockoff teardown
This wide-form-factor Game Boy is a knockoff from way back when the original system hit the market. You won’t want to miss this lengthy post that takes a look at what’s inside. [Thanks Neil]
