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. | Dig1t wrote: | 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 | throwaway81523 wrote: | 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: | http://www.peterholland.de/ultralog/ultralog.htm | | But it looks like it is already there!
