OnTarget TDS v3.85 Released

I just released an updated version of the OnTarget TDS program. The last new version was a year ago and during that time I've added several new features and made numerous general improvements. I will be updating the TDS History webpage with all the details but here are some of the high points.

  • Added a second Target Data window that has Standard Deviation and Circular Error Probability calculations for the virtual group.
  • Updated target data printouts with new data fields.
  • MOA/Milliradians output is now selectable.
  • OCW data printing.
  • Other improvements to printing, display, data export, calculations, etc...
The new version is available for download from the TDS Download Page.

I will be posting more information on TDS and some of the other OnTarget projects in the near future.

OnTarget TDS v3.81

There's another new release of OnTarget TDS, version 3.81, available for download from the TDS Download Page.

The significant change for v3.81 is the addition of the Import Point Data feature. TDS, and other OnTarget programs, are limited to gathering data from a single target image. If a shooter wanted to combine the data from multiple targets they had to export the data from TDS, and run their own calculations in a custom spreadsheet.

The Import Point Data function reads the point data .csv file adds those shots back into the currently selected group. This allows the shooter to create a virtual group using data collected from multiple targets over an extended period of time.

A good example of this is was done by the author of the Art of the Rifle blog. He shot six ten-shot groups spread over the month of January and wanted combined group information for all 60 shots. To gather the data he reopened each target project and exported the point data to a single .csv file. He then imported that .csv back into TDS. The resulting group showed him what he could expect from his rifle if he didn't re-zero each time out.

The Import Point Data function is another tool for gathering and combining meaningful data in the search for better accuracy and precision in our shooting. I've given one example of how it's been used. Let me know how it works for you.

OnTarget TDS v3.80 Released

This morning I released OnTarget TDS v3.80, available through the TDS Download Page.

There are seven new targets in the 50's range. Each target prints using only black ink and has an outer ring with a single inner dot. Shots must be completely inside the outer ring to be automatically detected.

Detecting bullet holes on a black and white target is a new feature for TDS and is much more difficult than locating holes in the red and blue targets. Give it a test and, good or bad, please let me know how it's working for you. I've done a lot of testing but I could use the feedback from the field.

In addition, I'm continuing work on the electronic target frame (see my previous post for more info and a YouTube link). The latest design has several notable new features. First, I've changed over from wired to wireless communications. The new communications link has a manufacturer stated range of one mile but this may be somewhat overstated. I can't be sure until I do more testing but I'm hoping for a kilometer. Second is an optional configuration using three microphones on one side of the target instead of a microphone on each corner. A three microphone configuration has theoretically limited accuracy at the outer edges of the detection area but it is much easier to set up and works very well inside it's sweet spot. Lastly I've switched over to new microphones that are more suited to the the application. The microphones have adjustable gain and detect the sound of the impact with better reliability.

During my latest basement tests, using an Airsoft pistol and various pump-up pellet rifles, the system is detecting about 95% of the impacts and the calculated position is acceptably accurate. As soon as the weather clears up in Colorado I'm headed to the outdoor range for testing with .22 and center fire rifles. I'll post the results here on the blog.

Safe shooting everyone!

OnTarget News

The OnTarget Precision Calculator has had a couple small improvements. If you have trouble printing from the program Email Me and I will provide a download link to v2.16.

The latest release of OnTarget TDS is v3.78 which includes, metric support, better printing, and several new targets. You can download the latest version here: OnTarget TDS.

I've been working to add a shot velocity field to both OTPC and TDS. For now the values are entered manually, but my plan is for TDS to communicate directly with the chronograph to get the velocity string, and automatically associate the data with the correct shot.

Lastly, for the past few months I've been working on a prototype of an electronic target frame. The target frame would detect the location of a shot and send the information directly into TDS. Each of the major components of the system have undergone initial development and testing. A few days ago I did the first end-to-end test of the system and created this video Target Frame Test. The target frame works by detecting the sound of the impact, in this case the tap of the pencil on the target, at each corner. A high resolution timing circuit calculates the time difference of the sound reaching the corners. That timing information is sent into TDS which calculates the location of the impact on the target and displays it as a shot on the screen.

The system shown in the video is designed as a test of the concept and is made up of breadboard circuits that are basically cobbled together. The test went very well. The shot locations are accurate and repeatable considering the lack of calibration in the system. The communication between the target and TDS was stable. My next test will be to detect an Airsoft pellet impact on a target and display the position.

Watch the video and Email Me your thoughts.

OTPC Update News

Version 2.10 of the OnTarget Precision calculator was released in February 2011 and has proven to be very stable with few problems. Over the last two years I have made several changes to the program to correct problems with the target printing and data export functionality, along with some general improvements.

Until now I have only passed the new version, OTPC v2.14, along to a select few users that were having specific problems with v2.10, and it has performed as expected. At this time I would like to expand testing of v2.14. If you are a registered user of OTCP v2.10 and would like to test v2.14 please Email Me and I will send the download link. I would like to have about 50 users do the update so I can track the process and correct any issues that crop up.

After successful testing I will be releasing the new software with an updated help system and full list of improvements.
