Well, OK, a review has already been done, but not in Dave's "unique" manner:
They cut a LOT of corners on that design, which is kinda too bad since it's a pretty cool form factor. ("The lithium polymer charger consist of a 1 Ohm resistor in series with a diode connected to the +5V USB." !@#$& ???)

Mine is much cheaper and has FFT:

Ummmm, nah, thanks :-)

Unreadable schematic and one color wiring.
I'll just go out and build one today ;-).

So? if those stop you then still need to learn a lot.
I doubt it.
In the situations I often have to work in that probably wouldn't even see the end of the day. Well, at least not alive. I've even had a wrist watch crock on me.

I had several wrist watches crock, this happened specifically when carrying big TVs through narrow doors. But you would be surprised how strong that is. You can even break the PCB and it will keep working. I have dropped stuff like that too, without any problem. Some worked for 25 years, and then was till OK, but replaced by more modern stuff. What I like about this system is that I can prototype in a few hours, and have it working, while others are still waiting for the peeseebee to arrive, and then often have to do version a, b, c before it is OK. And also making changes, if it is a one of, is much faster.

That sounds like a strict-liability lawsuit waiting to happen :-(

Well, I meant from RF exposure. Bzzzt ... *PHUT* :-)
In many of his reviews he's widely dismissed the DSO.

I dunno, I have this next to a 150 W PEP SSB. The wire (RS232 link) hangs over the coax, bit crowded space. I am using XLR 3 pole audio connectors for the thing, 1 ground, as it is leading, one power, one signal, do not use return signal, so no MAX232, just a transistor. Found some nice transparent box for it on the internet, ordered a few. And, if you like dogs, this is cool too: file://localhost/usr/local/httpd/htdocs/panteltje/pic/scope_pic/snoopy_2_img_2030.jpg

Well, 150W isn't too bad if shortwave. Kilowatt pulses are a different matter.

I love dogs, we've got three big ones. But the link doesn't work.

Nice! I had Snoopy as a Pilot, teeth clenched, scarf flying in the wind, trying to hunt down the Red Baron, plumes of smoke trailing his shot-up dog house. Hand-painted by my brother onto the driver side of my Citroen
2CV. When cars passed me (in a 2CV pretty much anyone passes you) the kids' noses were pressed against the window. "Dad, slow down, look!" The passenger side had him dancing, and the back had him as a soldier marching out of Fort Zinderneuf.Jan: Use monospace characters for this:

Hey Jan, If you want another pic project, the DIY electric car guys really need PWM motor speed control with a few bells.
