Mini-Mig Bill of Materials

[nBit7]

560M is 560Megohms (560 million Ohms, but resistors don't go that high)

Actually they go much higher: 6000000 M (thats 6000G or 6T).

Must admit I have have never seen one in the flesh (unless it was called an insulator).  I have seen and used 1Gig Ohm.

Oh yes, very useful, I could get a 0.1 ohm, tie one leg to ground, the other leg to a 1G, which would have the other side on an antenna, bridge the 0.1 with a 330 ohm wired in series with an LED..... then I'd have a nifty little device that warned me with an LED coming on if I was getting hit by lightning.

Hahah, that post made my day.

It's probably a better idea to use a piezo speaker for the warning, cos you wouldn't be able to see the LED when the lightning strikes :idea:

Thats maybe something we can build after we have finished our Minimigs   :-D

Some parts arived today (Going to make 3 minimig's pcb's from ebay).
But I think the listed DC-CON 2.1mm DC Power Connectors are wrong.
The Listed parts from Farnell (224947) are not 2.1 mm connectors but 1.3 mm connectors SO BE WARE !!
I think the right one's are Farnell (224959)
Can anybody confirm this if so the BOM.txt hase to be changed.

Well what i'm going to do whith the other two minimig'ies

I don't know, I just want one, it's just fun building him!!
I mean Her ! sorry miggie !

[wizard66]

Are the specs of this BAV99 okey to use ?

Infinion
DIODE, DUAL SOT-23
Voltage, Vrrm:70V; Current, If av:200mA; Case style:SOT-23; Application code:High speed; Common connection:; Configuration, diode:Dual; Current, If Vf:50mA; Current, If max:200mA; Current, Ifs max:4.5A

Can somebody familiar with dikigey order system point me out how to order that damn black square for minimig??
I will need just ICs from digikey, as other parts i can source locally.



im stuck here, and rohs part isnt available imo

 :boohoo:

[amazing]

yeah i have the same probs on that site
maybe it is that u need to order a minimum of 24 and they only have 3?

[wizard66]

A few bits and bytes from my e-mail's to digi-key:

YOUR QUESTION: is the 122-1519-ND the same as a XC3S400-4PQ208c-nd
It appears that these almost the same part.  The part you have quoted (XC3S400-4PQ208c-nd) is an internet nonstocking part.  The minimum purchase requirement is 120 pieces and manufacturer lead times apply.  

The 122-1519-ND is the same part but is the rohs compliant, lead free version.  It is available in any amount you prefer.

Bottomline:

XC3S400-4PQ208c-nd only order in 120 units
122-1519-ND  same thing order by 1 unit (yhea and lead free ) but backorder till 20-10-2007

cheers

 :-D  THANKS for clear it for me.
I will just wait for rohs part whatever it means (unharmed pandas, ic legs with socks, maybe  8-) )

[wizard66]

rohs means lead free..

This is exactly the sort of reason why someone should manually build a MiniMig first, before trying to get it manufactured, to ensure that the BOM is actually correct.  Otherwise you'll get lots of very expensive paperweights manufactured :-(

that was just my idea..if someone first build 1 and then make a proper list with all supliers and part numbers
that would speedup the building much more for everyone right?

[wizard66]

Yip Your right, Just 8 euro down the tubes
Now i have 10 DC power buggers useless on my desk.

Dutch ( en da's mooi klote)

[amazing]

maybe for the dutch hobbyists its easyer to do some group sharing?
like wizard said he ordered 10 of 1 part? if we can make some
group sharing it saves some cash
and in dutch(ons zeeuw ben zunnig)
