Thu, 24 Jul 2008 22:01:50 +0000 http://backend.userland.com/rss092 en I got the information that the branch I used in the previous version is an older one and that I should migrate to the so called thomas branch. So I did it and now it seems that all examples are working. Ok ... the varray example is not working. It somehow ... http://www.esden.net/blog/2007/12/31/cl-opengl-thomas-mac-os-x-bindings-with-native-glutframework/ I have adapted the cl-opengl bindings so that it runs with the GLUT bundle that is being shipped with mac os x. Most examples seem to work. The ones that do not work need a more complicated fixing. But the API should run correctly. (I hope so (tm)) You can get the ... http://www.esden.net/blog/2007/12/30/cl-opengl-mac-os-x-bindings-with-native-glutframework/ Some days ago I was able to program my BL-Cntrlers using PonyProg. I had some problems doing this because I do not posess a machine with a builtin Serial interface and Windows. The problem is that the programmer uses a bitbang protocol on the serial port with very stirct timing constrains ... http://www.esden.net/blog/2007/07/10/programming-the-bl-ctrlers/ Finally after some problems I was able to assemble three BL-Ctrl and the serial converter. Why I have not built four BL-Ctrl is because I broke one Atmega microcontroller while assembling the PCBs. Next step will be to test the BL-Ctrl modules. To do that I still need some things. First I ... http://www.esden.net/blog/2007/07/10/bl-ctrl-and-serial-converter-assembled/ Finally! Today I got my PCBs for the serial converter and BL-Controls. Now I can finally start building all up. It took an unexpected long time until they arrived. I hope that most parts I ordered will mostly fit on these small things ... the package with the parts looks very big ... http://www.esden.net/blog/2007/06/21/mikrokopter-pcbs/ Sadly I had to realize that the guys selling the PCBs are currently on vacation. I should have read their homepage more carefully. But the positive thing is that they will be back on monday the 19th so they will perhaps ship them tomorrow. Can't wait to get them and start ... http://www.esden.net/blog/2007/06/18/the-mikrokopter-pcbs-not-here-yet/ Today a DHL guy stood in front of my door and left a package full of parts for the BL-Controllers and serial converter. I still wait for the PCBs but according to PayPal the payment is through, so I should get them in the next days too. Hopefully I can start ... http://www.esden.net/blog/2007/06/14/bl-ctrl-and-serial-converter-parts/ Long time no post... Some weeks ago a friend of mine showed me these incredible machines at mikrokopter. I was so amazed about these small flying machines that I got myself the first parts for building such a small flying machine myself. Because I have nearly no money I split the purchases ... http://www.esden.net/blog/2007/06/12/mikrokopter/ After a long time finally a new entry here. Some time ago I owned a Powerbook 15". This one had a problem with its second ram slot. It was not detected by the system. I called Apple Care but they were not willing to fix that. I really was upset about ... http://www.esden.net/blog/2007/02/13/apple-and-their-support/ Ok I am back with one more rant on Lisp. Because of an idea I have, that is not yet ripe for decision, I was trying to get a graphics library that is portable and has a Common Lisp binding. Finally I got stuck on opengl and cl-opengl binding. I had ... http://www.esden.net/blog/2006/09/18/installing-cl-opengl-on-mac-os-x/
