       | Here is on on longimeters I like.

       | I created some logarithmic sliders for an electronics app I put
       | out on the App Store some time ago. I thought they were a good
       | match for electronics (Ohm's law specifically) because
       | electronics generally is logarithmic (resistors, etc. follow such
       | a progression).
       | 
       | A strange coincidence too that this site should pop up on HN
       | because I have been this past week or so working on a Javascript
       | implementation of a logarithmic slider so I can try a similar
       | Ohm's Law calculator on the web.
       | 
       | I think the web needs more logarithmic input controls. Don't you?
       | 
       | I think the significant difference between mine and this site's
       | is that mine you can specify the value to display and the slider
       | moves there -- further, when the user moves the slider manually
       | you can query the slider to find out what value is under the
       | cursor.
       | 
       | I'll have to dig into this site to see how to make my sliders
       | look nice.

       | My college physics lab had a bunch of old slide rules and other
       | small metal handheld instruments that all had "Made in West
       | Germany" printed on them. I always thought that was pretty cool.
       | 
       | I like that this simulator has "Made in Germany" on it, but wish
       | it had the "West" part for accuracy ;P

       | These are nice. I also like this one, that was made from a scan:

       | http://www.antiquark.com/sliderule/sim/n4es/virtual-n4es.htm...
       | 
       | It takes a very large screen to use something like that though.
       | It would be cool if these simulations could be printed on paper.
       | Then with some scissors and glue and cardboard, you could make a
       | somewhat usable physical slide rule.
       | 
       | I was going to suggest emulating this:

       | But it looks like it is already there! (

         | There is a mention of the K&E KE-LON slide rule which they
         | prototyped, but never manufactured due to the availability of
         | the pocket scientific calculator at that time. But I would
         | still love to see someone make a replica of the KE-LON (or
         | KeLon, however it was to be spelled), see the prototype picture
         | here: https://www.mccoys-
         | kecatalogs.com/KECollection/KeLon/keLon.h.... Of particular
         | interest is the Constants scale at the top of the back side.

           | I wonder if there are enough slide rule aficionados out there
           | to justify a Kickstarter.
