@h-wan: Alter resistor R205 to lower the supply voltage to the comparator. The AD8561 doesn't swing to its positive rail, so you probably don't want to reduce it to 3.3V. Try 1.8kR or 2.2kR and see what the output level is like. I can't make any guarantees, I didn't characterise the clock for that situation. For you reference, here's what the levels are like with a 5V supply to the comparator (as standard):

It's now the end of the month, and I'm closing the group buy. I'm still waiting on the PCBs, they have just shipped and should be here in a week.

I'm intending on doing things in the same way I did them last time. I'll start taking payments now. Those who have ordered only PCBs will have their order shipped as soon as I get their payment and the PCBs, those who have ordered kits will have their order shipped as soon as I get their payment and the PCBs and the components. I'll order the components this week.

Please make PayPal payments to the address shown in the picture (I'm trying to avoid spambots). Please make sure your payment has the address you'd like you PCBs/kits shipped to attached, and include you DIYAudio.com username in the comments. Here is the total cost for each participant:

- tagheuer, excluding shipping: USD66, total: USD75.55
- badrisuper, excluding shipping: USD46, total: USD57.62
- s3tup, excluding shipping: USD60, total: USD70.79
- zjaakco, excluding shipping: USD43, total: USD54.41
- WALTER BURKHARD, excluding shipping: USD36, total: USD46.79

- chungtat, excluding shipping: USD12, total: USD21.55
- skylab, excluding shipping: USD43, total: USD53.04
- goldkenn, excluding shipping: USD83, total: USD95.04

The shipping above is just basic airmail, and I'm sending them at your risk. I'm more than happy to send them by a tracked service, please PM me if that's what you'd prefer. I'd recommend doing that if you're country has an unreliable postal service.

If I've left your name off, or you think I've got your order wrong, please PM me.

Thanks,
Anton

There is also a bit of a problem. I've found that the supplied who I got the crystals from for the last groupbuy has now stopped selling them. I can still get name brand 11.2896MHz crystals, but it looks like I'm going to have to supply generic 16.9344MHz and 33.8688MHz crystals.

The PCBs arrived in New Zealand on Friday, but didn't reach me. I should have them tomorrow.

@mstr: Unfortunately you have missed the groupbuy. However, there will be PCBs leftover, and possible some DC kits. I'll contact you after the groupbuy and let you know if there are any kits left.
