Just got the latest batch of prototype boards back from Dorkbot, and I haven't even finished building the boards I ordered last time around.
Is there such a thing as PCB layout addiction :)?
I can see that I'm eventually going to end up with hundreds of PCB's hanging around my workshop with no time to build them.

I can help building them if you want ::)

That looks like my desk ;)
As long as you're having fun and you're not in the poorhouse (or the doghouse) because of it.
Nah its all good fun. This hobby is too much fun. That might be the problem :D.
I've got a wedding to plan (and pay) for next year, so poorhouse is definitely a probability, and also probably doghouse if I don't pay enough attention to flowers and wedding favours!
Wish me luck ;)...
pcb coasters for all the guests! ;D
She'll love that :D
On a side note, PCB coasters confuse me; what is the point in a coaster that has holes all over it?
If you don't mind me asking, about how much does a PCB that size end up costing through Dorkbot?
All the info you need here mate: http://dorkbotpdx.org/wiki/pcb_order (http://dorkbotpdx.org/wiki/pcb_order)
The price totally depends on the size of the PCB.
You always get three of each design when ordering. i.e. you cannot say 'can I have 1 PCB for this design, and 4 for this design' etc.
My last batch (some of which are pictured) was six designs, totalling 30 18 PCB's (three of each design). The total came to around $80.00 inc shipping to the UK. This works out to around $2.60 $4.50 per PCB which is a pretty good price.
EDIT: What am I talking about; my last order was 18 PCB's, not 30. I'm not firing on all cylinders today!
that is an excellent price, plus purple boards & gold pads. thanks for the info!
Just keep repeating my mantra "It's not a problem if I'm OK with it."
I have a feeling any extras would be bought up pretty quickly 'round these parts. ;)
C'mon, fill us in on what you've worked up.

I've almost done this several times. Not for wedding guests, mind you, but just for having around the house.
I was thinking of doing a design with several decent-sized drill holes. Then backing one side with thick stick-on felt. This would allow it to absorb the condensation from cold drinks in the summer. Without the holes and something to wick the condensate, PCBs would be crappy coasters, unless it was just for things like coffee/hot tea.
But it's kinda pricey. They'd end up costing about $15-$18 each. Not sure I want one that bad. ;D
Clearly the obvious solution to the coaster problem is:
1) Create large circuit with big empty circle in the center and pads on the perimeter
2) Add a battery and a small circuit that when pressure is applied to the top of the board (i.e., when a drink is on it), it lights up severael LEDs
3) ??
4) profit.

add a rumble pack and you can let people know when their table is ready.

You have thought about this !
Hey did you ever post your beer mandles on here?

In the latest batch there is:
-> A variant on the ROG Peppermill. A Mu-Amp JFet stage (lifted from the DLS) with the MOSFET driving it. I also stuck the SWTC on the end (like the DLS). This one will have a lot of sockets to let me tweak stuff.
-> A discrete baxandall EQ. Basically a tweaked version of the JFet Buffer -> Passive Baxandall EQ -> Tweaked LPB1 that was posted on the forum a while ago. I've tweaked the values etc. to get something I think sounds cool on my rig.
-> Escobedo's MS20 filter. I put diodes in the resonance feedback path, which I'll socket.
-> Voltage Doubler. 9V -> 18V (just like the roadrage).
-> State Variable Filter. LP,BP, HP outputs.
All good stuff. I've started getting into building my own filters to run loops from my DAW through; good squelchy fun!
Who knows, I might add some PCB Coasters to the next batch (or maybe not ;))!
