Dave makes a DIY camera dolly system that mounts under his work bench. It’s not complete yet, it possibly needs a 2nd rail platform, angled brackets, and better tripod mount, but otherwise works fairly well for a quick trial. Forum HERE
What was technology like inside a 1994 Motorola MicroTAC 7200 International GSM mobile phone? Motorola Brick Teardown The sales brochure! Forum HERE
No Script, No Fear, All Opinion
What’s inside a 1997 vintage Nintendo 64 gaming console? Forum HERE
Fundamentals Friday. Designing and measuring basic and precision opamp peak detector circuits. Forum HERE
Who else but Dave can take an hour and a half to review a multimeter! Agilent’s new 34461A/34460A 6.5 digit bench multimeter. A replacement for the venerable 34401A Quick links: Startup Labels Ratio ProbeHold Continuity Probes Statistics Overshoot Overload Diode Current Trend Plot Histogram Res Standard Bargraph Cal Check Cal Drift Wrapup Fan Noise Comparison AC Testing Specs Competition Software Conclusion Forum: http://www.eevblog.com/forum/blog/eevblog-489-agilent-34461a-multimeter-review/
Does basic office equipment have any salvageable parts? Dave dumpster dives to find out. Forum HERE
A first impressions video of the Tekway DST1102B oscilloscope. Also the DST1062B and DST1202B Same as the Hantek DSO5062B, DSO5102B, DSO5202B and the Voltcraft DSO-3062C, DSO-1062D Forum HERE The BIG Hantek/Tekway hack thread
Dave proves he has no fear by opening this can of electronic worms by posing the question – “Does Current Flow Through A Capacitor?” The answer may surprise you, or drive you into a physics induced rage… Vent your rage HERE Turns out you can measure the displacement current: http://personal.rhul.ac.uk/uhap/027/PH2420/PH2420_files/displacement.pdf NOTE: before commenting, please watch and understand that there are TWO types of currents.
