Mine serial number 1013 was waiting for me when I got home from work today.

Will test it soon.

Hello All's

#1006 received today, yay!

Visually everything is okay, but not turned on yet (i still need to buy a battery, doh!)

#1027 arrived the 22nd of April. Was send the 14th.
Just tested the mA range which works perfectly

My all-red binding post #311 arrived on the 15th, shipped on the 8th. I'm new to electronics, but it seems to work perfectly. Thank you Dave!

µCurrent Gold with SN #1003 arrived on 2014-04-25 (send date 2014-04-14). Quality is very good, no issues with insuficient solder wetting or tomb stoning.

It works well - see picture with test of crude CC load.

Mine (#001259) was in my mail box today morning here in Luebeck, Germany. It had a note saying that it was freed from customs.

I haven't got a battery for it, so it's not yet possible to test it, but I did a visual inspection and everything is looking good.

u271D · « **Reply #482 on:** April 26, 2014, 10:39:31 am »

does anyone know if this thing comes with a warranty? I've emailed & PM Dave after he said to email him and I've gotten no response!

I switch to uA range and my DMM to V (not mV range) and got a reading of .9995 My source is 1.0003mA so:
1.0003mA (+/-)0.05% = uCurrent output of 0.9998V - 1.0008V
Then you add in the meter (+/-)0.05%+5 count you get a range of:
0.9988V - 1.0018V. So if my math is right; in the uA range I am getting a reading within the limits of the uCurrant and my Agilent U1272A DMM. It is just not working right in the mA range.

If uA range work and the mA range doesn't then it can only be the switch or the mA shunt resistor, there is nothing else. Check the connections on those, something has to be wrong somewhere.
I'll be shipping you another one anyway.

how would I go about testing those two parts?

Yupp, thanks to Dave for being so clever to declare a value of only $25. Even if German customs would falsely calculate with US$ instead of AUS$, this would only translate to roughly EUR 18. In Germany, any imported goods with a value of up to EUR 22 (incl. shipping costs) is exempted from custom fees and from import sales tax. I guess many other (European) countries have similar exemptions.

In Lithuania (and I suspect in most EU countries), for example, you have to pay VAT (21% in Lithuania) if parcel value is higher than ~22 EUR (30 USD). Custom fee is calculated for product of value ~46 EUR (64 USD) or higher.
Fees are on the high side in my opinion, but the main problem is that any shipping adds to total value base for these taxes. This may lead to situations where shipping and taxes are >100% of original price of the item.

EDIT: Custom duties are applied only to import form non EU counties. VAT applies for goods from EU and non EU.

More were supposed to turn up today (they haven't), and more tomorrow. So that should finally fulfill the kickstarter orders and I will have spares for general sale.
I do still need to set up a shopping cart that integrates with my eParcel system though.

SeanB · « **Reply #489 on:** May 03, 2014, 04:39:45 pm »

Well, no 001345 arrived here finally in ZA. Sent 4/4/14, so it was all SAPO being efficient as usual.

Looked and out of CR2032 cells at home, so will get one Monday. Had one CR2025 which does fit, and the low voltage detection does work, as the cell ( NIB) expired 6/2009.

I missed the kickstarter deal; so if there are spares, I'd love to buy one.

rjk5378 · « **Reply #492 on:** May 05, 2014, 05:08:59 am »

Mine arrived safe and sound in Maryland USA just about 10 days ago. Will probably unload my original version at a hamfest or on eBay (which is where I got it in the first place <g>).

Please add me on the list for one of the spares. TY

Dave sold the previous version on Adafruit, so I'm pretty sure that his additional stock will be available through retail outlets like that. You don't need to beg.

gdewitte · « **Reply #494 on:** May 06, 2014, 12:58:32 am »

I think they're in here someplace, but so far my searches have not turned them up. What (and where) are the details for the current sources Dave built to test µCurrent GOLDs?

jonwhite · « **Reply #495 on:** May 06, 2014, 09:16:18 am »

i see micro current boards on daves desk behind that 2 channel scope can i have one please?

starblue · « **Reply #496 on:** May 11, 2014, 07:02:03 pm »

Mine arrived last week here in Germany, found it in the post box Friday night.

I did some tests today, a function generator in series with a 100k resistor on the nA setting.
Response is flat to 200kHz, 3dB down at about 280kHz. In the time domain there is a little bit of overshot.
See attached pictures.

Valen · « **Reply #497 on:** May 13, 2014, 01:54:26 pm »

Sn# 1440 has just arrived in the Netherlands. The Australian customs sticker says it was manually singed by an Acceptance Officer on 6/5/2014. So it only took a week to cross the world I guess.

Luckily I had a spare CR2032 laying around. BATT OK was a 'golden Go'. Haven't used or tested it any further though.

Dave, thumbs up mate.

DarkStar · « **Reply #498 on:** May 13, 2014, 05:00:01 pm »

I guess I should mention that I received #450 in great shape (about a week after shipping). Popped a battery in and everything seems to be functioning properly!

u271D · « **Reply #499 on:** May 14, 2014, 03:31:42 am »

on the 10th I got my replacement unit #826. After fixing the battery holder, all seams to be good.
