Default Design Progress

The basic and the deluxe designs were at their best towards the end of this whole process. The wiki shows a huge interest in both of them. We should try to move forward from where the designs were at that point. It helps to have the output relay in the basic design for example.

xaudiox, aka Ferdinand Calma - 5067 Abacan Malabanias, Angeles City 2009, Philippines - has a business selling his stuff on eBay and I can only assume that he is trying to hold us all hostage until he can add the basic and the deluxe to his product lineup.

Ferds, as he likes to call himself, has even sold stuff on eBay to Vladimir Simovich as evidenced by this letter that he photographed for his photobucket. Anybody that Ferd ever sold to on eBay has his/her full then current adress on photobucket by the way.

You just have to like people like Ferd.

Default Just because there are Elves

La Ode and I, we could not accept the fact that people's GB suffered.

So we silently cooperated and here they are!

Brand new boards, basic or fully 6 input relay switched, both with delay circuits, accepting 5V or 12V relays by the simple use of a couple of resistors or a jumper.

Both boards are single copper layer, hence they can be even more economic to make. I have the .brd Eagle format files (widely accepted by PCB makers).

Calling Ryssen et all to have a second look for mistakes, and if still interested, I will only send the .brd and schematic Eagle files to the new GB managers. You can then check with PCB makers if all is well and get quotes so to restart the GB.

CRT has done this for absolutely no personal gain, he even has DC B1 with shunts already as you know. It wasn't easy, we had to cooperate a lot. The guy is super. I congratulate him.

The only thing I want to suggest if the GB is resurrected, is to do the decent thing and the GB make for him a couple of free boards as a souvenir and a thanks.

He named the basic board ''HYPNOTIZE'' and the fully featured board ''MEZMERIZE'' inspired by his favorite band S.O.A.D

People, this is about as good as a simple solid state buffer can get. Enjoy.

Default Wow ... amazing ... thank you!

That is so cool!

I was also hoping to resurrect the GB with a new board design, but my schedule was going to be "sometime in the fall".

What a great thing to do! Thank you, thank you, thank you.

As soon as the wiki is back up I will up my order for boards to include crt's souvenirs.

WOOT!

I do not know if I have the resources, but whatever I can do to assist here in the US, let me know. Shipping to the US folks or whatever.
Thanks so very much for this. Now my 100 sk170's and 15 relays will be of use after all!!

You are welcome. Organize you people and the files are guarded for you. Only have a good look for any mistakes, I could not see.

CRT did not mention anything, it was my suggestion. I think its better for the whole GB to cheap in I guess, arranged by the new GB manager to be. It would be more symbolic. Then again, you said it first... Anyway, CRT and I want to thank you people for the interest you have shown into our little B1 twist so to make it a GB. Good luck with it this time.

Either way, Salas. At some point during the first round there was a proposal to include a donation to diyaudio and a thank you gift in the price of the boards.

I am still totally in favor of that.

My spontaneous offer stands regardless. It is simply an expression of my gratitude to you and CRT, as well as an expression of my relief that trying to rework the pcb design is off my "schedule" for the fall.

Thank you one more time.

I dont think Cogra that I used as pcb maker,can compete with e.x http://www.pcbcore.com/ with the price.And if I shoul use pccore I have to pay
tax and stuff as I am in euroep,so I think its better if sommeone outside of europe does the GB,as you dont have to pay tax when you recive the pcbs
(is that right)pcbcore has a quote system that we can use.What do you think?
I will assist in any other way that I can.

thanks for the work guys.
Salas, does the hypnotize have an issue still possibly with offset during power on/off as we discussed earlier?

I can front some money to have the boards made (cost pending of course) and can do some shipping. I am more uncertain about ordering quality boards and dealing with PCB manufacturers. Is pcbcore the way to go? I would be unsure about next steps if too many questions are asked. I would certainly order a small # first to make sure they work...
