This is a hack in the finest sense of the term. It not only allows you to capture data from an analog oscilloscope for later analysis, but provides you with a great tool if you’re posting on the Internet about your projects. [J8g8j] used an empty cashew container to add a camera mount to the front of his scope. This is possible because the bezel around the display has a groove in it. A bit of careful measuring helped him make an opening that was just right.
You can see that the red cap for the jar holds the camera and gave him a bit of trouble in the original prototype. This version has a tray where camera sits, which replaces the Velcro with didn’t hold the camera level the first time around. He’s also painted the inside of the clear plastic to reduce glare on the oscilloscope readout. Black and white images seem to come out the clearest, but it can be difficult to make out the grid lines. The addition of LEDs to help them stand out is one of the improvements we might see in the future.
[Jonas Kroyer] is a digital photographer, with a fascination with old cameras and pairing the two together sounded like a fun idea. Searching around on the net he fell in love with the design of the Zeiss Ikon Ikonette (1929-31), and found one with a chipped lens.
After dismantling the camera completely, it was found out that he needed the lens/shutter mechanism, the bellows, and the rails that allow the lens to slide back and forth. The bellows were glued to the body of the camera, but some careful prying and they were quickly removed unharmed. Next was to make an adapter so he could attach the lens to a digital DSLR camera, a steel plate and a Nikon Bayonet swiped off of a no name lens holds everything together. Rails were reattached using rivets, and the bellows were glued onto the plate. Other mods include adding small brass knobs to aid in adjustments, and a spring from a ballpoint pen to hold the original shutter open.
The new old lens is said to be easy to operate, and produces some beautiful images. Though since the lens does not have any modern day coatings it does have its drawbacks, like a diamond shaped flare in the middle of the image, which can be good when you want it, or partially removed in photoshop if you don’t.
Shots of this Canon AE-1 camera-gone-digital have a lot of people scratching their heads. Originally there were a lot of “that’s been photoshopped” cries but the video after the break shows that it physically exists. This particular model of camera hasn’t been manufactured since 1984 so there’s little chance that the company’s bringing it back in a digital format. What we have here is a classic camera body with a modern point-and-shoot fit inside. This seems to be a PowerShot SD 870 IS and we’d guess the original lens has been replaced with a plate of glass so as not to affect the PowerShot’s focus, and the “AE-1 Program Digital” screen is probably just an image on the memory card.
We admire the clean mod work necessary to produce this hack.

[Mike Bradley] wanted to use his oscilloscope to display 8 channels of digital signals. Alas, the analog unit didn’t have this capability. Not to worry, he threw together an adapter module that does the trick. Using a PIC 18F26K20 microcontroller he inputs four or eight channel digital logic (at 5V) and filters the output to an analog signal that the oscilloscope can interpret. What you see in the photo above is the result.
[Kieran] let us know about his hybrid analog/binary clock. The circuitry behind the clock is nothing too new. An Arduino combined with a Chronodot to produce an accurate clock. What we really enjoyed however was the creative implementation of an old British Telecom Linesman’s Multimeter as the case. The analog meter acts as the seconds hand, while a another display made of LEDs diffused with stripboard is the binary clock. The end product is nothing short of ingenuitive.
Kodak managed to release a product with a big fat security vulnerability. [Casey] figured out that the Kodak W820 WiFi capable digital frame can be hijacked for dubious purposes. The frame can add Internet content as widgets; things like Facebook status, tweets, and pictures. The problem is that the widgets are based on a feed from a website that was publicly accessible. The only difference in the different feed addresses is the last two characters of the frame’s MAC address. Feeds that are already setup can be viewed, but by brute-forcing the RSS link an attacker can take control of the feeds that haven’t been set up yet and preload them with photos you might not want to see when you boot up your factory-fresh frame.
It seems the hole has been closed now, but that doesn’t diminish the delight we get from reading about this foible. There’s a pretty interesting discussion going on in the thread running at Slashdot.
Analog clocks now a days get no respect. Everyone is digital this, or binary that, and we admit it is nice to look over and see the time promptly displayed. But there’s something about the quiet ticking and ominous feeling you get when around a large intricate clock that you know some serious time has been invested.
Nostalgia feelings aside, [Alan] from Hacked Gadgets introduced us to his Gear Clock. While it’s not a new idea, and in fact we have a few around the office, his concept really inspired us. His clock is driven via stepper motor and a PIC, allowing for the time to be fairly accurate. The only small problem he mentions is the poor paint job, but we think it looks amazing regardless.
