I posted a small update to my spoke tension visualizer based on user feedback.
This update supports the numeric keypad for data entry, which was an oversight in previous versions. I have a few computers but none with a numeric keypad so please let me know if I missed the mark. For tablet and phone users the onscreen numeric input mode is now presented by default, which saves a mode-switch for every spoke (thanks to David M. for the suggestion). Last but not least, input validation is less restrictive so you can use hotkeys for cut, paste, print, etc. while editing.
I also re-tooled the setup screen to allow two kinds of bladed spokes: 0.90×2.2mm and 0.95×2.2mm. These are for Sapim CX-Ray or DT Aerolite spokes and the correct choice depends on the exact measurement of your batch of spokes. Sapim says nominal CX-Ray thickness is 0.90mm, which is a fine way to go by default, but some people find theirs closer to 0.95mm. This isn’t a huge deal because the point of visualization is to show relative differences, which are independent of scale.
Since you’ve read this far I’ll point out a couple features that may not be obvious. First, you can hover your mouse over any point on the graph to see the conversion from deflection to tension. Second, you can save your work by using the File > Print function of your browser to make a hardcopy or save as PDF on some systems. Mac users have a PDF option in the lower left of the print dialog. I’ve done a fair amount work to strip my site headers and footers so the resulting document looks nice and can be shared with customers if that’s your thing. Note: your browser may add unwanted headers and footers but these can usually be suppressed in browser settings (try Print or Page Setup menus).
Suggestions welcome. I don’t work on this tool often but keep track of requests so they can added when time permits. What would you like? More spoke choices? New ways to save graphs? A way to link to completed graphs? A publish to Facebook or Instagram feature? Other tensiometers?
