I saw that he DSO213 is the new version but they’re about $170. But the 212 is better than the NANO with higher freq. I wish there was a store I can go to play with one before putting in an order.

 

Is anyone interested in building a DIY oscilloscope from scratch based on the ARM STM32F746G-DISCO?

The price and performance cannot compete with what is commercially available. However, it would make a great ARM learning project.

If there is sufficient interest I can start a new blog. I can provide estimates on cost and performance. This can also be done as an open source project.
(If there is interest, I can move this to a new thread.)

It certainly sounds like an interesting project.

 

149.00 + 22.00 shipping, good deal?

Only if you can replace the screen. Does that model come with asteroids?

It's originally pac-man, but maybe asteroids could be retro-fitted... you'd have to ask the manufacturer

 

I have one of these. If this is in good shape, it's a good deal: https://www.ebay.com/itm/HP-Agilent-54601A-4-channel-100-MHz-Oscilloscope-Very-clean/283449503708

CRT, but 4-channel and quite capable.

 

We got asteroids in the military

 

Personally I like the new cheap scopes. They take up less space on my bench and work reasonable well. The DSO5202P is not bad for $270. Can’t get over how light they are compared to the old CRT ones.

Kinda seems to be one one of those things though where for that money i can add 200$ more and get a much better scope. Honestly more i look at it for what I am thinking of doing a microscope set up to display on my pc makes allot more sense. I don't see a scope on allot of guys benches doing cell repairs visa via You Tube. They all have a micro scope though.

So the Subject should have added - for Phone repair?

Oscilloscope was invaluable troubleshooting my latest project. I have heard great things about Sigilent... And yes more money usually better.

As for microscopes there is a $30 - $200 range online (VGA-4K). You want clear video, built in screen helps (bigger the better) with hmdi output being nice feature. Also the focal length should be far enough that you can work underneath. Fortunately I'm limiting myself to 0805 at the moment and can see well enough with my reading glasses. But for phones I can see why you would want one.

 

I have an AmScope optical microscope without a camera. It does 10x and 20x with a very good working distance. It wasn't very expensive and it's been really great.

I actually take my glasses off to work with 0805 and other smts... yes, I'm that nearsighted

Which one do you have Yaakov?

I have this one: https://www.amazon.com/gp/product/B005C75IVM/

But I must say that it has been so empowering that if I'd known I would have gotten this one: https://www.amazon.com/AmScope-SM-4TZ-144A-Professional-Trinocular-Magnification/dp/B004UBNIMC/ and still might.

$700.00 bucks!

It's still cheap for what it does. And the trinocular part means I can put a camera on it, and it's a zoom, and the boom is very nice.

 

I used this one at work. One disadvantage of being retired is you loose access to all the nice equipment.

Oops wrong thread...

To replace my Fluke 113 - It's almost useless...
Which was given to me and was not bad until I replaced a bunch of 100k and higher resistors - thought they were bad




I will order more of these. They are now $19. This one is rock solid... did my own tests with it. Nice build with good shunt, diode dividers and ceramic fuses. It almost comparable to the protection circuitry in Fluke. The large fuse is smaller which is fine... fuses blowing is a safety feature.

Next one I order will have thermocouple.

 

The Fluke 113 is a basic instrument for a tool bag. Fluke has very specific models for different applications, this one is not for electronics, its for electrical work.

It's still a top quality meter.
