[Peter Johansson] has taken it upon himself to build a medium format camera, from scratch. We know this is a shock to some of you, but this camera uses traditional medium. There is no sensor. He will be loading it with (gasps) film. He bought the lenses pre made, but everything else is being constructed by himself. Probably the most notable parts are the aperture and the shutter. The project is about 80% complete right now. We can’t wait to see it finished.

After letting it sit around for about 3 years, [Blake] decided it was time to fix his broken 15″ television. A little trouble shooting showed the problem was with the inverter. The backlight would come on for a few seconds, off for a few seconds, then repeat. By freeing the Magnavox 15MF400T from its metal case he got it working again, but couldn’t find the source of the short. His solution: build a new case out of non-conductive material. Voilà! We have the 15″ LEGO monitor.
It’s not a very complicated LEGO build, but it’s the first case mod we’ve seen in a long time that isn’t strictly gratuitous. Join us after the break for more pictures. Continue reading “Broken TV Brought To Life In LEGO Body”
The XBMC team has posted a teaser showing the current state of the ARM port of this popular open source media software. We’ve embedded it after the break where you can see the package boot up and playback HD video. In it we see that the system is decoding the signal well, but image rendering needs some tweaking before this will be ready.
The hardware used is a Beagleboard which runs a 600 MHz ARM processor, has OpenGL 2D/3D acceleration, puts out HD via a DVI port, and is selling for about $150. The 3″ by 3″ board can be connected to a network using a USB WiFi dongle. Although integrating XBMC by hacking TV firmware is a long way off, we’d consider velcroing one of these to the back of our HDTV and getting rid of the hulking PC behind the entertainment center.
Can’t wait for this version to hit a stable release and don’t mind using hardware that is just a bit bigger? Check out this guide for setting up XBMC on the $200 Acer Aspire Revo.
Hackaday alum [Ian Lesnet] tipped us off about some reverse engineering of the HVR-1600, an analog and digital television encoder/tuner. The project was spawned when [Devin] noticed his Hauppauge HVR-1600 didn’t tune channels in Linux quite as well as it did in Windows. He had a hunch this was due to improper initialization settings for either the tuner chip or the demodulator.
To fix this he used two test points on the board to tap into the I2C bus. Using a logic analyzer he captured the command traffic from the bus while running Linux, then while running Windows. By filtering the results with a bit of Perl, and comparing them by using diff, he tracks down and finds the variation in the commands being sent by the two drivers. After a bit of poking around in the Linux source and making the necessary changes, he improved the tuning ability of the Linux package.
[Devin’s] work looks simple enough, and it is. The difficult part of this process is being smart enough to know what you’re looking for, and what you’ve got once you’ve found it.
[Bruce] has designed a push-pull tube amp that has enough gain to connect to a portable audio player. The design is closely related to his OddWatt offering from a few years ago. The new amp has many redesigned circuits and the new hardware choices drop the price tag of the parts by about $50.
This little wonder pumps out 5-7 watts and [Bruce] is please with the end result. It doesn’t put out quite as much low-end as the KT88 amp we saw last year, but compared to some other iPod speaker solutions this provides stellar audio.

[John Boiles] introduces us to dimlet, his portable network controlled light dimmer. Inside the box is a fonera 2100 router that is running openWRT connected to an unnamed AVR microcontroller. Right now, he’s controlling the unit with his iPhone. It has three modes of control; a manual “slider” mode, an accelerometer controlled “dance” mode, and a programmable “tap” mode. You can download all the source code and schematics on his site.

[Ben Heck] may be the coolest person ever (take that [Adam Savage]). You would think that after producing so many laptop versions of gaming consoles he would grow tired or we would be bored of them. But no! We love each and every new production – including his latest laptop-ified Ps3. Not too much in the terms of ‘new’ comes from his latest article, but it does reaffirm some things including: why make what you can buy, cheap foam sheet should be purchased by the ton, and use the screws from an overheated Xbox 360 when you lose the Ps3 originals. Oh, and [Adam] we were just kidding, you know we will always love you. Check out a video after the break.
