What's in the mailbox? 📬 📦

And oh by the way, you sent me down a rabbit hole with the mushroom oscilloscope videos and everything that follows, and I'm spending my weekend repackaging all of my transistors into esd protective baggies -- hopefully it's not too late for them.
his mind had gone out for a stroll and fell deeper down the rabbit hole...

I'd focus on the ICs, especially anything MOS based. :)
But, one day J201s will cost $15+ so I guess protect it all :)

Wwwaaaaiiiittttt......
Whiiiiccccchhhh mushroom videos?
because those are two very different rabbit holes...
 
Yes, two different rabbit holes, but you're responsible for both...
you have to have 2x channels to watch these though

If you get a cheapo, don't forget your DC block. I've read about some that didn't handle oopsie DC well.
2 channels can be handy though. There are some DIY curve tracer circuits out there that can be very useful. May be worth keeping an eye on Govdeals.com. If you have a local tech college, follow them.
and,
When anyone here who has a doubt about ESD or is interested in ESD has time, I suggest watching this


It's an hour and 20 minutes but a very, very very good presentation.

Edit. It's also the most entertaining one probably ever made. It also covers the somewhat discovery of ESD, which is phenomenal and sad.

My ICs are fine, ICs are already in protective enclosures and shielded from esd. I'm n more worried about my fets and transistors . And my mind is fine...
 
Not technically in my mailbox, but it did find its way into my living room yesterday:

I went to three stores and tried a dozen different guitars, and in the end the one I thought might win beforehand did. Myrtlewood with such straight grain seems fairly uncommon at this price point from what I can see, but the sister store had another one that was very similar as well. I took one of my resonant filter EQ pedals along for plugged in testing, and it really enhanced the very simple onboard Fishman system. Somehow I've never even owned an acoustic guitar before, so I'm hoping this will kick start some new pedal designs.
 
You mean the device itself? I'm not sure about that one.


I'm familiar with the NTSC signal because I worked at a TV repair shop for about 20 years.

Now I see that it actually says NTSC at the bottom. :ROFLMAO: 🤦‍♂️


My guess is that you worked in some form of broadcast? Maybe at the news station or cable company?
