| 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.

| it had the "West" part for accuracy ;P

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

|
| 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! (

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