Projects / Chronojump


ChronoJump is software and hardware to track jump, run, and reaction time and pulse. It uses a contact platform suitable for two events (in-platform, out-platform), and also a chronometer printed circuit designed ad-hoc in order to obtain precise and trustworthy measurements. Chronojump consists of free software and open hardware. It features a simulator that can be used if you don't have the hardware.

Recent releases

    Release Notes: Management of the user local database location solves problems with bad directories and sqlite. Sounds are now available. Treeviews are more compact and have accelerators. A problem with losing decimals was fixed. An endless loop when destroying the window was fixed along with a crash in when editing simulated events.

      Release Notes: A person can now change weight between sessions. The following peak power formulas were added: Harman 1991, Shetty 2002, Canavan 2004, Lara 2006 male applicants sports sciences, 4 Lara female voleibol, and university related formulas. Peak power formulas can be applied to any simple jump without TC. Stats show AVG and SD depending on selected rows. The report shows AVG and SD. Graphs show AVG. Graph size depends on the data to be graphed. Lots of GUI improvements were made.

        Release Notes: The Windows version now executes with Mono. Sqlite 3 is used on Windows and Linux. Automatic conversion of old data is done. A test image window with a graph and information was added. A new directory structure is used, so the Windows and Linux releases are in the same compressed file. The program now cannot be executed two times simultaneously. Agility tests on runs with images and descriptions were added. EditReactionTime and EditPulse were added.

          Release Notes: Configurable "realtime" bells on repetitive events were implemented. The best and worst values of TF and TC are shown. This allows ChronoJump to be used also as a training method. Reaction time was added. Treeviews of repetitive tests now show average, total time, and standard deviation of every test. Repetitive events get recorded in temporary tables for being recovered if there's any crash. The "finish" and "cancel" buttons work better, asking to the user to touch the platform if needed. Standard (typical) deviation was added to statistics.

          •  26 Oct 2006 16:50

            Release Notes: A unique window for executing events, with a configurable graph and progressBars, in quasi-realtime. Simulated events now are truly simulated. Autoincremental copies of the database on each chronojump execution. Reactive jumps can finish after time if a jumper is in the air (deselectable). Dates are now internationally supported. Q Index and Dj Index support in the main window. Search has been implemented on person_recuperate. Many bugfixes and improvements in usability. Translated to Chinese, English (GB), Finnish, French, Spanish, Swedish, Portuguese (BR), and Vietnamese.
