| 24 sep 2020 09:20:35 | Arduino wattmeter | Guenter2 | Doh, that did not occur to me, it's an AC wattmeter, of course it can measure negative voltages - oh well, feeling pretty dumb now! ;-) \\ Very cool, that little wattmeter is exactly what i needed, thanks for sharing!\\ Best regards,\\ Guenter |
| 24 sep 2020 09:04:09 | Arduino wattmeter | Freddy | You don't have to modify the circuit. The wattmeter can measure negative voltages. Connect the current measure side so it measures also negative. The result is a positive power measurement. |
| 23 sep 2020 21:10:31 | Arduino wattmeter | Guenter | Hi Freddy, cool project! I have a question - i need to measure the current on the high side of the load - how would i have to alter the circuit to implement this? I thought of disconnecting the common lead from the voltage measurement part of the circuit, and providing the 0.55V offset (half of the reference voltage) for the positive input of the opamp with its own resistor divider. The voltage measurement would stay the same - except it has no common connection to the current shunt. Does that make any sense? Could that work this way? Thanks, Guenter |
| 31 aug 2020 20:45:17 | Additive synthese waveform generator | Subrata | Thank you so much for your permission for to use it, solely for educational purpose. I have cleaned the UI a bit, leaving only the application for learners to practice. I also have given credit to you with a direct link to your site. |
| 30 aug 2020 10:08:02 | Additive synthese waveform generator | Freddy | It is all in one JS file. Only the HTML elements are marked-up in this HTML file. And you can find the style descriptions in golfvormsynthese.css |
| 29 aug 2020 20:16:08 | Additive synthese waveform generator | Subrata | Many thanks for the response. What about the UI? And customs JavaScript calculation (if any). |
| 29 aug 2020 20:13:16 | Additive synthese waveform generator | Freddy | It is not open source, but you may use it for educational purposes. You can find the link to the javascript source (golfvormsynthese.js) in the HTML source code of this page. |
| 29 aug 2020 15:44:52 | Additive synthese waveform generator | Subrata | Hi Absolutely loved your work, I was just wondering is this code open open source for young learner at uni? If so how can then I access the source code (the application), I would like to add something extra and to combine few tools for audio engineering students in UK, as for educational and research purpose only. Wold like to hear from you at your convenience. Kind Regards Subrata |
