DSLR infrared camera conversion

ir_conversion

[Jerry] recently got a shiny new DSLR camera and was looking to do something with the old Pentax DSLR it replaced. Having performed a few point and shoot IR conversions in the past, he was pretty confident he could tackle this conversion without too much trouble.

He located the service manual for the camera and got busy taking it apart. He had to desolder the main board to get to the CCD block, where the sensor, IR cut filter, and the shake reduction motors are all located. The IR cut filter was pried off without too much trouble as it is only secured with a clip and an adhesive foam gasket.

Once things were disassembled, the real work began. He had a little trouble cutting the IR filter he purchased, so it took a little bit of elbow grease to get things exactly the way he wanted. Once he got the filter in place, he carefully re-mounted the sensor block to ensure that it was set at the proper height.

Once things were fully reassembled, he tried taking a few test shots, but found that there were some focus issues due to the IR filter being thicker than the original IR cut filter. A few manual tweaks in the camera’s debug menu and he was in business.

Be sure to check out his photo stream to take a look at some of the pictures he snapped with his new IR camera.

Coffee powered Car-puccino

We can only imagine how amazing this coffee burning car smells at it speeds down the highway at a maximum of 60mph. Don’t jump out of your seat so quick to get your own, while the idea sounds fantastic, the mileage will bring you back to earth rather quick. At 3 miles per kilo of coffee, it can turn that £36 210 mile trip into one between £910 and £1,820 with a stop to re-bean-fill every half hour!

Still, the Car-puccino is an amazing conversion, and we’re getting closer and closer to Back to the Future’s Mr. Fusion

DIY Lincoln welder conversion

[Fritz] built this 600 joule capacitive discharge spot welder in a case scavenged from a Lincoln plasma cutter. All of the circuitry was designed by [Fritz] and the schematics are available on his website. He has a few other welding related project also documented on his site that are worth checking out. While this isn’t the first homemade spot welder we have seen, it is definitely the first one with a case mod. If you are not up to the challenge of building one quite as complex as [Fritz]‘s example, a microwave can be used as the donor appliance in simpler designs.

Kawasaki KZ440 electric conversion


[Ben Nelson] didn’t even know how to ride a motorcycle when he started on this electric conversion of a 1981 Kawasaki KZ440. The engine wasn’t a loss since the bike was nonrunning when he purchased it for $100. The permanent magnet Etek motor was $500 and each of the four yellow top batteries were $160 (only three pictured). He says that the majority of the conversion work only took two weekends. The resulting, still street legal, ride averages 20 miles per charge with a 45mph top speed.
