This has to be the most annoying thing about Altium.
When searching for something as simple as a voltage rail to check what it is connected to, there might be tens or hundreds of nodes, and this zoom problem makes it impossible to get context of what a rail is connected too without closing the...
No worries. Here's another picture (ignore the fact that the top looks a little funny; I think the cut has left it a little warped).
Hopefully the "sealed" end is displayed clearly and you can see the solid rubber part at the end that is able to absorb the shock.
I wasn't even thinking about the...
The aren't heat-shrink; they're rubber.
Basically like a tube with one end blocked off with more rubber.
You just force the standoff into it. No "tightening" required, and tightening will only affect the perspex at the top and the PCB, not the rubber boot.
And they definitely absorb shock. The...
I purchased a development kit recently, and it came with these little rubber things.
It took me a minute to work out what they were, but they seem to be some sort of rubber shock-absorber for the board's standoffs.
I think of them as 'boots' or 'socks'. :)
Any idea where I can get more, or...
I've got a device I need to connect to multiple power supplies and a controller for testing. The device has several modules that all operate off different voltages (12V, 24V and 48V).
The device under test (DUT) has a housing that is used as a common ground point, with all the supplies and...
Thanks for that; I'll read it when I get a chance.
The text/example is talking about latch-up and the risk of overvoltage. It says that the capacitor can be overcharged, causing failure of the parasitic diode.
They don't actually mention COM in this part other than to say Vs goes negative...
I'm a bit confused by an explanation I found in a Fairchild Application note: AN-6076 - Design and Application Guide of Bootstrap Circuit for Hign Voltage Gate-Drive IC
Specifically, page 3 at Fig. 9 and Fig. 10, and the explanation of why Dbs conducts.
I can understand the "example" part, but...
How have you selected the bootstrap capacitor size and type?
Are you getting a large enough voltage across it (i.e. could the charge time be too long for this value)?
I figured that was how they got the volume with such a small battery, but like you say, they only use "squeaks". It's not really feasible for proper music, is it? I'm wondering what kind of power I can pump through a small speaker like, say, one from a PC motherboard/case.
Thanks for that. Just...
I'm currently designing a little musical birthday card, and I've finished the SD Card/FAT/WAV code in my STM32. I still need to write the LED part of the code, but I've started thinking ahead to the hardware and power setup.
For the proof of concept I used a little TI headphone amp chip (since...
I've purchased some male BNC to dual banana socket adaptors like these:

I've also purchased some reverse gender ones (male banana plug to female BNC), but I can't seem to see if the physical pin spacing/separation on equipment...
I see a lot of RF schematics with capacitors that don't specify units or SI prefixes.
For instance, a capacitor may simply say "0.01".
Is this generally its value in microfarads?
i.e. 0.01 = 0.01uF = 10nF?
Or is that assuming too much? Does it simply require you to take a logical guess?
