content: The temperatur inside the oven is taken as start temperature for the profile and then the profile is independent of the oven temperature. The rate and duration is programmed in the settings.In the cooldown phase the heaters are turn off and the oven waits till the temperature reaches 50°C.So it's some how fixed in duration.The software implementation is a simple state machine so it should not be hard to change the behavior ...

content: What was the solder that you were originally looking for?Amscope do articulating arms btw. But to get more space see if the stand is reversible and clamp it down to the edge of the bench, might pay to remove the microscope to avoid toppling it over while trying.If that works then you could possibly make up a heavy duty right angle bracket, mount it securely flush against the side of the bench, then mount your stand. You could bolt everything down so no accidents.A flexible right angled HDMI cable might be better so you can secure it to the microscope without causing strain on the port. A right angled extension cable for the ring light would be better as well (or just replace it if it sucks).

content: Truly the scope of dreams that thing... I mean honestly it's about time Tek got serious about building a good scope. They were king in the Analog days but their DSO's have always seemed to be not as good as the competition. I like the design philosophy here, they really did think this whole scope through, it's fast, easy to use, 8ch is amazing, 6.125Gsps, 2Ghz is plenty for a general use scope, etc. They seem to have gone from last place in this category to first.

content: The battery is made from Cyclon cylindrical lead-acid cells originally from Gates Corporation but now produced by Enersys. They are much higher performance than prismatic lead-acid cells due to their construction and are still popular in high drain applications. I do not know why they used them here.http://www.enersys-emea.com/reserve/downloadarea/download.asp#cyclonIf they properly voltage derated the solid tantalum capacitors and observed their surge current limitations, then there is no reason to expect them to fail.The TL497 switching regulator is TI's less popular variation of the 78S40/MC34063 constant on-time with peak current limiting design. Higher frequency comes at the expense of efficiency because switching losses increase while conduction losses remain the same but these parts were never particularly efficient at any frequency; 60% represents a lower bound which would be found in a low output voltage buck configuration when the internal power diode is used and the internal diode produces more than 20% of the losses just by itself. Modern higher frequency parts are just better but would have even higher efficiency at low frequencies at the expense of capacitor and inductor size.

content: Thanks for the info on the lead-acid cells. I wonder if they behave better long-term than standard SLAs.Sort of agree with you on the switching side, but not completely. Yes switching losses are greater at high frequency, but the inductor and capacitor losses are far less in a well designed circuit. You have less proximity loss in a small value inductor, you can use a better ferrite material for reducing losses from magnetic hysteresis. The high frequency and loop response mean the dV/dt should be less in your capacitor and you can consequently use much smaller capacitors with better properties.

content: I producedmy 1stYouTube videolast night showing how to measure the power conversion efficiency of a USB power adapter from 100V to 240V. I used aPeacefair PZEM-020 watt / power factor meterI bought from banggood to measure the input power, voltage, current, and power factor. I hooked up temporarily without a case because I wanted to try it before investing the time to put it in a case. It works very well and I will be building it into a case.I figured the best way to get started is just plunge in and do it. I had quite a few production glitches with his video including me slipping the decimal point reading current values, forgetting to turn on the outlet power switch, focus issues. Production improvements I need to make include; getting a monitor so I can manually focus, matching the kelvin temperature of the lighting to get a good white balance, & making an outline of what I want to say instead of just winging it. The video has flaws but I am happy with it for my first attempt. I hope to improve as I make more.There are links to all of the equipment I used, the test data, and test configuration schematic diagram on the YouTube page.

It's explicitly pro-science unlike many other Tesla-related channels.I try to keep it accessible for less technical folks.I'm a ham radio guy (AJ6BD) so there's wireless/RF experiments. Plus: Repairs and restorations. Maker projects. Rants. Fundamentals. Experiments.

The other inspiration is Virgil Matheson (who will never read this), who taught AC Theory at the North Dakota State School of Science--we met in a freak occurrence and it changed my life forever.As an aside, as of this writing, I'm suddenly searching for a new job in Software Engineering, so channel subscriptions and traffic are especially appreciated. I don't see this being my full time work, at least not in the near future, but every bit helps.Thanks and 73, -mP.S. I welcome any suggestions for the channel, for driving subscribers, or for managing the rats nest of files I'm accumulating from video production...
