[-Elepro-]

i have not many time but i'm trying to finish the definitive prototype....
here the photo of the PCBs.... the small one is for the dual sensor (double side) probe....
other pictures soon.....

bye

[-Elepro-]

finished...it works very well.....i will post soon a pdf with user manual....

[-Elepro-]

Features:

• Range +/- 5375 gauss (with AD22151 sensor) or +/- 1650 Gauss (with A1302 sensor)
• Normal, peak-hold and average mode
• 1024 sample per reading in normal mode, 64 in hold peak and 131k in average mode
• On board tactile push buttons to reduce cost and wiring
• Two sensor (double face) probe with storable calibration (sensivity value from 0.250 to 6.000 mV/gauss) and polarity for each one
• Auto zero set at start-up and at sensor change... + zero set button
• Lcd backlight button

for who want buy the gaussmeter... i sell PCB+MCU at 30 euro (i have 11 pcb)

for the other components:

in the list i did not count male connector and cable for probe.... everyone has an unused usb cable at home....

sensors are not in the list

I'm in!
I figure resistance is futile...

Now... about that LCR meter...

BTW the Mouser shopping list adds up to $25 w usps shipping. The A1302 sensors are $1.50 while the AD22151 are more like $20 ea off ebay..

Looking good, I'm in.

Hi, it's my first post to.

i'm in to.

great work Elepro

[Folkcafe]

I'm in

Count me in for one.

[belwar]

Count me in for 3.

[copperheadroads]

count me in as well if theres no problem with shipping it to canada

[David King]

That leaves only three.

I multiplied the mouser order out by 11 and it comes to $191, no big savings there except on shipping which is hardly a consideration compared to sorting out all the parts and mailing off a dozen packages. I would consider having Elepro send all US-bound boards to one address via the most secure way we can afford and redistributing them from within this continent. It might make sense to split Canadian orders off from the US ones just to save the 2 weeks per border crossing.

[David Schwab]

That leaves only three.

Oh... is this a group buy? Well count me in then!

[David King]

I imagine Elepro can get more boards made up if needed in another 4-6 weeks if there's lots of interest?

[mkat]

I'm in.

[BadHorsie]

I am in for one if no problems with shipping to TEXAS.

Thanks
Stan

This sounds like a good idea.
