Konrad
ZUSE et l'invention de l'ordinateur ZUSE et la racine carrée (Zuse and the computing of the square root) |
Powerpoint
presentation for the Computarium, Diekirch, 26 Oct. 2010. In French. Supplementary part showing the solution of the square root by Zuse. |
| L'art du secret: Part 1, Part 2, Part 3 (unfinished) | 3 first parts

Python Compiler for the
HP-65 calculator (version 1.3 of 22 March 2024) LilliPython EXECUTABLE and SOURCE code (version 1.34) with examples in .zip folder. A 50th HP- 65 anniversary project! |
This is a huge
54 pages report on the creation of an original Python compiler for
the 50 years old HP-65, the first programmable hand-held scientific
calculator of the world. Recursive routines using the Labview programming
environment are created to produce a virtual instrument (VI) allowing to
input simple Python programs to create the HP-65 specific routines. The
report is divided into 2 parts: Part I : Recursive expression evaluator Part II: Recursive cross-compiler The LilliPYTHON package contains the application LilliPYTHON1.34.exe, using the free Labview Run-Time package (not included, must download version 2021 SP1 32 bit which needs Win10).; the full Labview source code is in a separate folder. Claude Baumann has created here a practically world-unique software package, using his extensive skills of Labview and recursive programming. |
| BAUMANN Claude | Development of a Labview G-Code generation program for 2.5D CNC contour offset toolpaths (version 1.0 31 October 2023) | A very
complicated and long report, with original program code developed by
C.Baumann to solve tool path problems when using a CNC (drill or laser)
machine. |
| BAUMANN Claude | Lab report on the PIC signal generator (version 1.0, 05 December 2022) | A report on the
construction of a very small battery-powered signal generator, to be used in
a demo of the HP16500A logic analyzer. |
| BAUMANN, Claude
(co-author Francis MASSEN) |
Lab report of the TTY converter (version 1.1, 02 November 2022)) | A very extensive, complete and long report on the design, creation and programming of the TTY/USB converter for communicating between a vintage ASR-32 TELEX and a PC. This is heavy PIC and Labview stuff! |
| BAUMANN, Claude | Bringing back to life a COLINBUS Profiler CNC_Router (29 Mar 2021) | A very
extensive 62-pages report of the restoration of a Colinbus CNC profiler, an
heritage of our late member
Jean
Mootz.
This is as a major research project by Computarium
member Claude Baumann and also an original endeavor to combine modern
stepper motor drivers, Arduino and self- developed electronic interface to
revive a dead machine (which many would have thought being unsalvageable)
which was sold in 2009 by the
Elektor magazine as a kit. 46 pictures or schemata. |

Dynamic
binaural sound localization based on variations of interaural time delays
and system rotations
(JASA, 138 (2), Aug. 2015) |
Claude Baumann,
a Computarium crew member, has published an outstanding paper in JASA, the
Journal of the Acoustical Society of America. The co-authors are Chris
Rogers (Tuft University, USA) and Francis Massen (Computarium). The paper gives new insights on how to locate a sound source in space, using calculations performed on the interaural delay-time. The PDF is here. [Copyright 2015 Acoustical Society of America. This article may be downloaded for personal use only.
