Last time I checked in, I had added the heated build platform and a Paxtruder to the Makerbot. However, things were not quite perfect: things were not sticking to the platform, and I kept getting occasional jams in the nozzle. I could tell things were not quite moving, because I could see the filament “snaking” […]

I got around to assembling the heated build platform for my Makerbot. The heated platform is super-useful, as it prevents printed pieces from warping as they cool, and removes (sometimes) the need for a “raft” to help pieces adhere to the platform. Heated build platform in action, printing an Escher cookie cutter I’d […] One of the many appealing features of Apple’s iPhone is the ability to make custom ringtones. However, as with most things Apple, there is a an official (and limited) way of doing things, and an unofficial (and much more fun) way of doing things. Those who use sites like KubaDownload will know all about the […] At NYU’s ITP program, the Processing and Arduino programming environments are widely used. Since my main interest in the OLPC is to use it as a controller for projects, and since most of my projects are built using those two tools, I was very interested in getting them running on the OLPC. In addition, both […] I’ve continued to explore HDR (High Dynamic Range) imaging, trying out different tone mapping algorithms. The following image was processed with the Mantiuk algorithm, and gives a nice, illustrated look: Compare it to the original image: In imaging, dynamic range refers to the difference between the brightest and darkest values in a scene. Cameras are not able to capture as much dynamic range as our eyes, and most display technologies are not capable of representing them. I’ve been doing some experiments with HDR imaging and processing, because I think the process […] I’ve moved the information in this post to a dedicated page here. I received a lens I had ordered, a Ukrainian Hartblei 35mm f2.8 Super Rotator. This is an unusual lens in, in addition to focus and aperture controls, it also supports shift and tilt movements. There are other tilt and shift lens, but the Hartblei is unique in allowing the tilt and shift axes to move […] |
