I asked for the Zeitgeist schematics, but....

Edit: I just remembered Rob mailed them to me. As he also posted the Benjolin schematics I presume he won't mind me posting the Zeitgeist.

How can you use the board graphic for making a pcb when it's got the component graphics on it like that?



Thanks

I noticed a small error on the schematic diagram. It has C9 - pin 9 on the delay chip - as 9100nF. Looking at the overlay and photo here it appears that the extra 9 is a typo, it should probably be 100nF.

On the Benjolin post there is a graphic with the components and a graphic for using a transfer with no components to print on the transfer paper.
Is there something I'm missing?
Please tell me.

Thanks

yes, it's just a 5v line for the delay chip. 7805 work fine.

This might be sacrilege, but I'm currently working on an alternate PCB layout for the Zeitgeist with external pots and jacks. Here's an image. Not making it fully available yet, as I haven't had the time to confirm that it's working perfectly.

Hi can anyone tell me what these potentiometers on Rob's board is called? I often need ones this size!

And can anyone explain the 10 pin connector for the jumper if I wanted to make one myself?

Those are 9mm pots, several manufacturers make them, Alpha too.
Just need to specify that you want vertical mount.

What exactly are the components labeled "HDR_3"? I recognize everything else and have most of it on hand, but I've never seen these before. Are they some type of transistor?

They are headers, you can just use hookup wire.

Could someone describe what this circuit does? I'm having trouble finding a good description anywhere. I found a video - but it doesn't go into much detail...

I know it's a delay circuit, I'm familiar with the pt2399. I was assuming this does more or is interesting or different than the other 2399 schematics floating around...?

Hows the new board layout coming along. Am curious and have a couple of 2399 laying here waiting... Wink

And also... was the "old" pcb layout with pots but without components ever released?

Subject description: what are the specifications
Reply with quote  Mark this post and the followings unread

I've built both the Zeitgeist and Benjolin at a Harvestworks workshop years ago and now I want to fire them up again - - but I can not find the power supply. Please remind of the circuit specifications. It looks like the Benjolin wants two: v+ and a v- DC referenced to a common ground and the Zeitgeist only one v+ DC to ground. I see I have a 5 pin female DIN power connector on my chassis converted from a Sears/Craftsman tool case.
Thanks,
Steve

sorry to push again, but if Rob sent u the files to build your own Zeitgeist....why u posted only schematics and parts placement and no layout for pnp transfer??...It's like an invitation for dinner with no food on the table.... Shocked

it's not hard to edit the posted jpg to remove the parts outline and leave just the copper. this is DIY, afterall Laughing

I'm checking the board with the components and I have some questions:
what are the pots function names?? (from left to right)
the CV input is to control the delay time?
what is SENSOR doing?(HDR 10)
what are the functions of JUMPER and the two HDR 3? jumpers for a different settings ?
the JUMPER next to the led says + and -, should I consider - as Ground??
I will try to etch this board in these days, not so many parts and looks also an easy build...any recomendation?
