We have now ordered the axles and parts that make up the frame for the display. I am nearly completed with the programming.

Spend a hard day debugging and cleaning up the code in ermat. We also had a briefing with George, and found out that the HC12 cards should arrive in one week.

I have worked further on xirmat and ermat to use run-length coding. Now, the output of xirmat is compressed and then hard-coded into ermat’s souce code. Ermat then uncompresses the data, one byte at a time. The compression is highly effective, and reduces the 113 KiB file to a 3 KiB one, which can be [...]

Just got an e-mail from George. He reported a problem with the delivery of the HC12 cards. Our supplier, www.nohau.se, has changed the delivery date to the end of May, when the project will be long overdue. The bad thing is that we already ordered, and according to their original offer the equipment would be [...]

Thanks to my friends in the Maths group in Project Voxel I have been able to complete the matrix calculator called Xirmat. It has reached version 0.01 and is able to dump the individual frames in text format to stdout. Now we “just” have to make it go out on a real LED display. The [...]

The project group has been divided into smaller groups such as Maths, Electronics and Mechanics. I am a bit between Electronics and Maths since I work with the programming part. First I have to write a program that pre-calculates the individual frames.

Yes, we had another meeting with George where we started to design the system. Adam has found a manufacturer for large LED arrays, and although the delivery time is 6-8 weeks it is exactly what we are looking for. As a control system we will probably use some kind of Atmel AVR chip, it seems [...]

We finally met our manager George in the voxel project today. We outlined how the project will be continued, and we will take small, incremental steps towards a display. He also taught us how to calculate with matrixes, really interesting stuff indeed. The meeting lasted for two hours, and we will work on the LED [...]

Finally we met George today. We briefed him about our progress and decided what to continue with. He learned us about matrices in mathematics, an essential skill when working in three dimensions. We are going to work with some sort-of LED solution, but we will make incremental step, not continuing before we have working prototypes [...]

We finished writing our PM, as a result of having too much time beacuse we couldn’t get in touch with George. He was supposed to come home from his business trip today, but despite our efforts in contacting him, we have not succeeded.
