I bought my AN8008 from easydeal88 on Amazon - they sent me a 'gift', some kind of 5 cent plastic bag that covers remote controls, and that arrived late July.  After I complained and asked for my money back, they sent me the actual item.  I ordered July 15th, the AN8008 arrived Aug 5th.

Amazon don't make it clear that the item ships from China and I feel conned because I paid more than it was listed for on eBay because I thought I'd get better service - I was VERY wrong.  I would probably buy from eBay if I bought another one.

All that said, the AN8008 that I eventually received seems like it is a keeper.

After going through that trouble, hopefully it will serve you well for a long time. :)

Looks like there might be a world shortage after Dave's video.

:-DD maybe Dave's in cahoots with the cheap Chinese meter factory?  We'll know soon if he gets one of those posh Oz hats with the wine corks hanging from it ;)

I changed my 100 uF electrolytic to 2 x 1206 47uF Tanceram caps (fancy ceramics) that I had in a sample box, I can't seem much difference before and after when scoping the 3.3 volt rail, still looks noisy - I did screen captures if you guys want to see them.  I also fixed some dry looking joints on the fuse holders.

Tested volts and current against my calibrated Keysight 34461A, volts are spot on, amps are slightly low: 34461A = 3.02 A, AN8008 = 2.98 A.  34461A = 301 mA, AN8008 = 299 mA.  Maybe I messed up the calibration some when I improved the soldered joints on the fuse holders as now there will be less input resistance.  Maybe it was like this before I started it may even be in spec - I didn't check before getting out the soldering iron, I 'fixed' it when I saw they looked dry.  Anyone know how to calibrate the AN8008?  I guess I could try to tweak cal when/if I swap the shunt resistors out.

It's been nearly a month since Dave's video and I still can't find anyone selling them that's located in the US. I guess I'll have to buy one from China.

Simple: You just have to reprogram the little external EEPROM with new values!
