Attempt to power up telescope failed. Seems that the
fuse on the power supply was burnt. Bypassing the fuse shows no
extraordinary current consumption - but the scope still does not
move. Apparently the control circuits are defective. |

The controller circuits removed from setup for
repairs |

Attempted repair of RA controller circuit: Opto
couplers and Darlington transistors replaced. However, the circuit
STILL does not work. I am at a loss. |

Søren Jessen has repaired the RA and Dec controller
circuits. Apparently the fault, I couldn't find, was in the
soldering of the connector. The Dec unit also had Opto couplers and
Darlingtons replaced.
Furthermore Søren improved the design by placing a red/green LED on
the board, to indicate the direction the motor is running.
Thank you for helping, Søren! |

Downloaded the source to v2.2.18 of the Linux kernel
and the source to v.3.0 of RTLinux. |
| 010114 |
Linux kernel recompiled and installed. My netcard
does not work anymore :-( |
| 010115 |
Netcard problems fixed by compiling the netcard
driver as a module and inserting the statement modprobe
eth0 near bottom of file /etc/rc.d/rc.sysinit
I don't know why this is necessary - it wasn't with the
kernel distributed with Redhat 6.0 |
| 010116 |
Pathed the Linux kernel with RTLinux extensions.
Compiled and installed both kernel and RTLinux. The test programs
supplied with RTLinux work!
The base real time OS is now ready. I can start developing
applications. |

Started developing a prototype of the Control Module.
Making prototypes i C and C++ |
| 010122 |
A minimum prototype of the Control Module written in
C++ is now operational. Expanding it with FIFO communication to
Linux mode applications. |
| 010123 |
Developing a test application that talks to the
Control Module through a named pipe (FIFO). Its a simple text mode
application using curses. |

The documentation goes online. |
