            The website is way too slow to be of any use. Response times are unacceptable for teaching or demonstration use.
            I hope this is a temporary glitch. I am on fibre....

              • bug report

                I´ve been tryin to simulate this circuit:

                http://www.docircuits.com/circuit-editor/1410/deb-s-555-astable-mv

                But all I get is a runtime error.

                Is this caused by an error in the circuit?

                Thank you very much

                • Real time feel for oscilloscope in hobbyists licence

                  When using the oscilloscope in the hobbyists licence it is basically a repeat of the plotter. An oscilloscope should plot the waveform slowly, from left to right, just like a real one. When i simulate low frequencies, i'd like to see the waveform being plotted and not get a ready file showing all the data. I wouldn't know if this comes with the Premium virtual instruments.

                                  • Include components by part number and their datasheet specs

                                    Add components by part number. Make them searchable by part number and include their specific specifications by part number. For example: SCR Part Number C106D1. If i selected that component for my circuit and clicked on edit details, the same values I would find on the components datasheet would already be plugged in. I would definitely be a paying member if it was easier to just plug and play components by part number, with already included specs, w/o having to take my time by substituting and manually adding specifications. Thank You

                                        • Oscilloscope doesn't work

                                          The oscilloscope shows a trace on the output graph, but it's the same as the voltmeter graph. When I show the oscilloscope panel, I can manipulate the knobs, but the trace is always 0 volts / no waveform. Something is wrong with the oscilloscope.
