The device is detected as HID.</p>An Open CVMeter - Meurn:md5:9cfb307f4724c42ba304b651e651b6702015-12-17T16:22:31+01:002015-12-17T16:22:31+01:00Me<p>Do you need a fancy Rigol scope to use this? Is that a USB host or slave connector? I would assume that this device is a slave but from the picture it looks like a host connector.</p>
<p>You don't really talk about the software side of it. My assumption when reading that you needed USB because you weren't putting a display on it was that the USB would be to connect it to a computer to act as the display.</p>
<p>Maybe you are connecting a USB storage device? Then plugging that into the scope to plot the data on it? Do those scopes do that? If so then I suppose it shouldn't be too hard to plug the stick into a computer for plotting if you don't have the scope.</p>
<p>I ask because I might be interested in the kickstarter but not if it requires an expensive scope that is outside my budget to use it.</p>An Open CVMeter - limpkinurn:md5:d76a96c674d692602b39a0ece3def5bc2015-12-15T07:46:21+01:002015-12-15T07:46:21+01:00limpkin<p>@<a href="http://www.limpkin.fr/index.php?post/2015/11/24/An-Open-CVMeter#c9385" rel="ugc nofollow">Kris</a> : I just pushed it to the repository.</p>An Open CVMeter - Krisurn:md5:e711e2a20a00b43ff0aa00601a7e62772015-12-15T02:47:37+01:002015-12-15T02:47:37+01:00Kris<p>Is the BOM published anywhere?

So I don't agree that "most ceramic capacitors lose up to 80% of their capacitance". Only low voltage, high value (>1000pF), surface mount caps using screwball dielectric materials.</p>
