I would if it were mid-june. I'm so swamped with school, work, and wife right now that I know I would forget something or someone.

Either that, or be so slow in getting things done that my sterling reputation would be tarnished.

In any case, the next month is not a good time for me.

I wouldn't mind organising it, although I'm in the UK and most of you folks are in the states, although shipping for a few boards is not very much

I would be interested in two sets.

I'd be interested in two sets as well; no rush though... I have paypal available.

I would be interested in two sets too.
thanks.
post #36 of 720
I'd be interested in 1 set of 3 boards.
post #37 of 720
I would be willing to organize this for us in the US.

P.S. I would like a set.

Depending on price I'd be interested in two or three sets of boards.

Glassman, is the layout compatible with 0805-parts? (easier to get I think)
Otherwise, a version designed for leaded components would also be nice.

For this buffer 0805 parts are sufficient, except for the emitter resistors. I try to use 0805 where it's possible because the are easier to get. 1206 is starting to getting "old" and hard to get (reason? the are "big"). It's not harder to solder 0805 than 1206. Even 0604 is quite OK.

Yes, it is harder to solder 0805. It's manageable, but it goes considerably slower. 1206 is a snap to solder, I'd take it over through-hole resistor any day of the week.

nothing stops you from using 0805 parts in place of 1206.. it could look not so sexy but it will work just okay.. I'm not gonna use leaded components, they are large, nasty and requires a lot more drilling and also double layer board, this would cost a lot more and I think it really isn't neccessary in such application..

also I was thinking about selling the board together with the pin headers, becouse tangent told me it's difficult to get the right ones in US.. you need ones with very fine pins, like this one:


it would cost $2 more for one set / three boards
post #42 of 720
Yes, you can use 0805 where 1206 is expected - I do this all the time when I forget to buy 1206 parts or forget to realize that high precision resistors are available only in 0805, usually.

the most recent layout:



I'm already talking with a few board manufacturing houses about details.. circa 30 sets requested by you so far and seems like it won't grow any higher..

peranders, would you be willing to sell three boards with the components for them as well?? If so, I'd be interested

I have pcb's so those I can sell but ready made would be possible if I got an order of 200-300 pcb's but not by hand a couple, sorry. They aren't very hard to solder by hand it only takes time. At work it takes a couple of minutes with machines

How much would you like to pay for a ready made buffer? (as little as possible of course) Post it here or send me a private message.
post #45 of 720
I'd like to solder it myself, but it's very hard to get small quantities of SMD parts, so I'd have to buy hundreds of resistors for one set of buffers. I just wondered if you had any spare parts for them lying around you could send out with the bare boards.
