Making a Wall Power Adapter for a Digital Camera

Instructables user [txoof] was unhappy with the fact that Olympus didn’t manufacture a wall power adapter for the E-510 camera and decided to do something about it. The resulting new power adapter is described in this article. What it amounts to is a fake battery pack made out of plywood.

A 2.5mm DC power adapter is attached as seen in the picture above and the fake battery contacts are made with a thin brass or steel plate. According to the article, a steel soda can or bean tin works well for this.  Google sketchup with the slicer plugin is used to make slices of wood to be glued together in a “battery” shape.  Alternatively, something like this would be a good project for a 3D printer or CNC router.

Although there is nothing that revolutionary about this hack, it solves a problem that many people have with cameras or other electronics without a readily available wall power supply. This can be especially evident when trying to do time-lapse photography or other activities that need a long time span.

Interactive digital fireplace is great for those chilly winter evenings

We’ve all seen them – those fireplace DVDs that seem to pop up on grocery store endcaps and get traded in white elephant gift exchanges. If you don’t happen to have a fireplace in your home they might make a reasonable solution, but [Nick] from the Gadget Gangster thought it would be far better if you could create your own interactive digital fireplace instead.

Using the Gadget Gangster Propeller USB platform and ProtoPlus board, his fireplace merges various video segments together based on user input, and plays them on any TV that comes equipped with RCA jacks. The process is fairly straightforward, and involves wiring up switches along with audio and video output to the Propeller board via the ProtoPlus board. The remainder of the work is done using software, requiring the user to select and encode video segments for storage on an SD card. [Nick] does however provide a whole set of clips for download, should you want to take the quicker route.

After encoding and categorizing the video clips to coincide with the “stoke” and “add wood” user input buttons, the Propeller does the rest of the work, randomly selecting clips from the appropriate category when requested.

The result is admittedly a bit Lo-Fi, though we thinks it’s cool and prefer to call it “retro” instead. It might not be a Hi-Def fireplace recording, but it’s far nicer to snuggle up to a hand made fireplace rather than a DVD you picked up as an afterthought.
