As it turns out, it requires some long-forgotten math skills (and patience!) to get a 3D-position from the wiimote outputs. I started with a 2D position determination.Below you see the top view of our setup. Cam A to C represent the three wiimotes, each...
So for the last part we needed a way to get an x,y,z coordinate. We had some idea's how but we ended with Stereo vision.With just 2 motes we could calculate an x,y,z coordinate, since 2 lines in space intersect only trough one point.This seemed...
The first version played videos directly from the SD card, which worked as intended. However, it was difficult to change the video that was playing, and also made the replication process a little difficult. We need a good 10-12 of these running, each...
OK, after rifling through the local Maplin £1 or less bin, I found 2 x Massive 6v dry batteries, at 50p each. Needless to say they were purchased immediately. After building a little header one of the batteries now connects to the PIC control board...
This log describes the additions to the 65C02 instruction set added by the M65C02A core. As indicated in the previous project log, Checkout, the M65C02A core is a significant enhancement to the microarchitecture of the M65C02 core. The changes in the...
fig-FORTH 1.0 now running on the Chameleon. The source for this interpreter was provided by user enso of 6502.org.All that is required to get fig-FORTH 1.0 to run is to edit the configuration data at the beginning. In particular, only two variables need...
I successfully built a quarter of the program counter on perfboard. the bread boarded one and the perfboarded one have been connected and I have a (partially breadboarded) 2-bit program counter, it counts from 0 to 3 and then rolls over to zero again,...
I'm back!last weekend I got around to soldering the ~120 transistors that make up most of the program counter.as of right now I think this is the most densely packed board I have made for the computer (and possibly ever).here's the schematic:and here's...
I can’t claim originality here... as I remember the XENON machine at a past TPF which had NIXIE tubes instead of the standard VFD displays. I always thought they were cool. Now that I’m designing Star Trek: The Mirror Universe; I’m thinking that I want...
10/21/2013: Between stenciling sessions the house got struck by lightning about a week ago... so I've been digging out of the random bad electronics and such. One of which is my Color LaserJet which I need to finish the apron. Anyway; tonight after...
The dev. has slowed due to an inconsistent Z axis on the machine. The milling motor was too slow and has lead to damage to the cutting head and then the whole Z axis. And the X and Y is too slow. There are plans to upgrade the axis to a belt driven system...
To whomsoever it may concern,The project turned out to be a bit tough. So I joined a PhD in Computer Vision. The method I would like to experiment with is bag-of-words. Therefore, I will try to detail this as hypothesis, experiment and observation. Also,...
Things are still slow going for me. But I have made some progress on the enclosure. This is the color scheme I am shooting for. I removed any extra plastic from the inside to make room. I also cut out the front bezel leaving just a lip for the plastic...
Working on the badge dimensions, I took a digital caliper and measured a few bits on the earpiece. It's roughly 46.51 x 16.09 mm and shaped like a surfboard. The narrow end is about 5.14mm tall while the other is about 12.38mm. The microphone is encased...
