/challenges-projects/design-challenges/experimenting-with-supercapacitors/b/blog/posts/supercap-magic-meter-circuitIntro This episode describe the circuit in my SuperCap Magic Meter. The meter circuitry is designed into an Arduino shield which will plug onto an Arduino Uno R4 Minima. This MCU has a 14 bit A/D and a 12 bit DAC that will be used with the shield, a.en-USTelligent Community 12https://community.element14.com/challenges-projects/design-challenges/experimenting-with-supercapacitors/b/blog/posts/supercap-magic-meter-circuitMon, 11 Sep 2023 15:14:58 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:09859196-76ff-458a-b819-ee6d4256ad01dang740<p>You did an excellent job explaining the circuit in the video.</p><img src="https://community.element14.com/aggbug?PostID=26702&AppID=419&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/challenges-projects/design-challenges/experimenting-with-supercapacitors/b/blog/posts/supercap-magic-meter-circuitTue, 15 Aug 2023 19:22:44 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:09859196-76ff-458a-b819-ee6d4256ad01DAB0<p>Nice design Douglas.</p><img src="https://community.element14.com/aggbug?PostID=26702&AppID=419&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/challenges-projects/design-challenges/experimenting-with-supercapacitors/b/blog/posts/supercap-magic-meter-circuitMon, 14 Aug 2023 17:38:02 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:09859196-76ff-458a-b819-ee6d4256ad01michaelkellett1<p>Hello Doug,</p> <p>It would be great if you could post the schematic as a static picture or .pdf so it&#39;s easier to study it. I find videovery hard to follow for this purpose (I know others feel the opposite).</p> <p>Thanks !</p> <p>MK</p><img src="https://community.element14.com/aggbug?PostID=26702&AppID=419&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/challenges-projects/design-challenges/experimenting-with-supercapacitors/b/blog/posts/supercap-magic-meter-circuitMon, 14 Aug 2023 14:12:06 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:09859196-76ff-458a-b819-ee6d4256ad01scottiebabe1<p>Looks like a nice little widget. How often to do plan to update the display? Perhaps once per second or every 10 seconds?</p><img src="https://community.element14.com/aggbug?PostID=26702&AppID=419&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/challenges-projects/design-challenges/experimenting-with-supercapacitors/b/blog/posts/supercap-magic-meter-circuitMon, 14 Aug 2023 13:15:11 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:09859196-76ff-458a-b819-ee6d4256ad01colporteur1<p>I look forward to following your progress Doug.</p> <p>I have two questions.</p> <p>How are you achieving precision?&nbsp; I&#39;m old school. Component specifications needed to produce the voltage accuracy you are suggesting would be expensive. I also don&#39;t see any trimmer pots to fine tune. Can you share some insight?</p> <p>How is the cap discharged prevented from going to low?</p><img src="https://community.element14.com/aggbug?PostID=26702&AppID=419&AppType=Weblog&ContentType=0" width="1" height="1">
