Going off the grid (not me not now but...) we are looking at Tesla batteries for energy storage. These would be charged from solar panels. It is reasonable to assume the panels are not going to charge at the rate of an AC operated 240 volt one, is that alright ? Will they charge properly ? Of course there is the option of taking them initially to the station and charging th

I'm making another fast pulse generator, shopping FETs, and noticed a few possibly interesting gizmos: RF MOSFETs. They're built for linear operation. At a glance, they seem to have fairly beefy SOA curves. Up to 600V, too. "N-channel enhancement mode linear RF power MOSFET Ideal for class AB and C industrial, scientific, medical, and commercial applications. VDSS = 500 V ID25=

Less than $100 US. For people who are familiar with current low end prices. I suppose they're crap to an engineer, but bear with me. Any recommendation for either a handheld or a PC/USB oscilloscope that might be fun to use with consumer drones? I see some are for automotive use, is there something in that? In the measly selection of less than $100 oscilloscopes, what qualities should I...

Well, I appreciate the advice thusfar, but that thread is getting built up quite a bit so to keep it "real" I start this one. I have found out that all the guy wants is a regular house refrigerator and a toaster oven. Nothing else will run off an invertor. Lighting will all be low voltage, stove and furnace off propane and A/C off a generator, maybe diesel, maybe something else.


Anyone Ever Read the Usage Agreements?

I looked at the Foxit Reader license agreement and found this. I'm not able to search the agreement, I can barely read the small font and the window only allows me to see a tiny portion of it at a time. Nothing obtrusive here! Then on top of insult, they want to force Macafee products on me along with a bunch of other products! The software may collect usage informat


Can LPC812 pins (NXP ARM uC) be shorted briefly?

Is it ok to short a port pin on LPC821 micro controllers to GND and maybe also to VDD for a second without frying it? Only one pin at a time. I'll be receiving systems with weird field failures tomorrow and I won't have a chance to change a port pin status in the code. -- Regards, Joerg http://www.analogconsultants.com/

As far as I know, using an oscilloscope for drones, I have absolutely no use for the BL's logic analyzer. But it looks like the inclusion of a logic analyzer is a huge value. Another concern with the BE is that apparently it is discontinued. Looks ike most of the problems people have with those two oscilloscopes are caused by their inability to use a PC. Just to check my understandi...
