Barracuda Legend Kit Problems

[Qiaozhi]

Ok, thanks a lot. One last question. I need a replacement for LT1054 , because it cost 5 Euro. I replaced LF412 by TL082.
And is there a sprint layout file from the geotech baracuda rev a?

You can replace the LT1054 with an ICL7660A, but be aware that the maximum input voltage for the 7660A is only 12V, whereas the LT1054 can go up to 15V.
The 7660A is well known for letting out the magic smoke if you exceed its maximum ratings.

There is no Sprint layout for the Geotech Baracuda REV-A.

What is the minimum voltage for the geotech baracuda? Can i run it with a 9V battery?

I have a problem with the gerber files. I want to print it for toner transfer and i have the top copper layer which looks fine for printing,
but the bottom copper layer looks like the pcb itself, red.

The input voltage range for the Geotech Baracuda REV-A is +7V to +15V, as described in the Build Document.

The PCB layout is not designed to be replicated at home using nasty chemicals.
The options are:
1. Send off the Gerber files to a PCB house.
2. Order a PCB from silverdog.
3. Make your own single-sided layout suitable for manufacturing at home.

i would be choice point 3 and will go whole Barracuda Legend Kit Problems way. i must collect all those problems on my *** hole.

I obtained a REALLY NICE PCB from KT315, purchased my own parts and had a nice working unit for under $30 USD. For just a few more Dollars you can have the GeioTech Board and all parts from Silver Dog. Why bother burning your own board ? I understand it's cool to be able to say "BECAUSE I COULD" but some times a little cheating is good too. You still can say I put it together with these two hands. LOL

Because it cost me less than 10 Euro and its just a little project for a pinpointer. I have everything at home and i just need the parts.
I have already asked kt314 for the price a week ago , and i sent him a pm today. I think i will buy a board from him, i just need the partslist lol.

I have heard that he made little changes to the board , so i think the partslist is a bit different too.
Can you give it to me pls. This will speed things up.

Or i will send the gerber files to pcbway and get 10 boards for 18 Euro and sell the rest of them.

Or i will search for a surf pi pro layout which is easier to build and to etch. Is there a single side sprint layout from the surf pi? Not the longboard pls.
