GBA1000 rev4 Build Log

I've bought a board and components from oldman1000 and am just going through my BOM to source the remaining missing components, mainly the passive stuff.

I've been using OS62s Mouser project as a reference (thanks OS62) but it seems that some of the EMI filters for L90, L100-L103 (ACH32C-100-T001) are out of stock for a month at least. I'm looking for a replacement but to be honest I'm not really sure what the requirements are - am I trying to match a certain bandpass frequency or what? Would ACH32C-104-T001 work instead (3.5-200MHz instead of 2-6GHz) ? I can't tell from the BOM what the value of the part should be for L90, L100-L103, to be honest I'm not really sure what I'm looking for.

Has anyone here got a build manual (or just notes) if such a thing exists? I'm aware that there are certain optional components (for example, depending if you fit a 50MHz or 100MHz oscillator) that you either should or shouldn't fit depending upon the setup and I just don't want to make a mess of things.

Thanks

I find these info on the GBA1000 user guide made by Georg Braun and translated in english by Kristian Karlshøj with add by Troy Silvey.

(So the credits are complete :) )

@stevebootes

Digikey have this item: 587-1771-1-ND
Here a link: http://www.digikey.it/product-detail/it/FBMJ3216HS480NT/587-1771-1-ND/1147096

Is a EMI filter 48 OHM / 6A from TAIYO YUDEN, try looking his datasheet.

The ferrite bead 742792117 of Wurth is out of production and you cannot find in the Wurth site.

Click to expand...

Filters are not crucial, just short them out and it is sorted.
 
I wasn't able to find this user's guide on the web, someone passed me this guide on EAB.
I tried to write at kristian karlshoj asking permission to redistribuite his guide.
If Kristian gave permission i upload them somewhere and post here the link.

(edit) ----------------------------------------------------------------------

Both kristian karlshoj and Georg Braun gave me permission (thanks again) to share the GB A1000 user's guide, here the link:

My board finish but without IC34:



And power on :



Big afternoon of tests now if I have time for this :). I'm so happy :)
 
Impressive. Well done.

I'm starting the main board this weekend after practicing my SMD soldering skills on kipper2k's Video Hybrid kits.

Eager to get on soldering now!
 
Perfect job

please i need info for Fet audio, i not found in Italy
 
I think you speak about the 2 FET transistors, no?
Me, I have found them onto ebay in England.
 
2 fet on list, t1 and t2 are mpf102

@yamakakiche
i have ic34 if you need
 
As I said, I have bought them onto ebay. It's a lot of 6 units.
If you need, I can sell you 2 ones. I'll make no money. I ask you only
the price I have paid for them.

The price was (shipping include): 6.47€
so for 2 units: 2.15€ + shipping (I have to look at the price)
Let me know if you're interrested.
 
@piacc64 thanks but i have ordered one ^^

@Tuxbar81, I want these transistor ! Pm me !

I've flashed the boot rom for the 8mb of fast in 32 bit and test with a game but i have and strange sound with the right way. I think a broken transistor. Some of frequency are amplified but the rest no... The left seems normal.
