The LipSync PCBs arrived!
I'll clean up the nibbles on the edge with a dremel later on.
There's a hiccup with the LipSync BOM. Several of items are sourced from Qosina, which strictly deals only with companies and not individuals. One of those items is a mouthpiece that I simply cannot find anywhere else online. Eventually I'd like to set up purchasing through my local makerspace, but the organization is dealing with some problems right now and I don't want to add to the stress.
Luckily I was able to find an AT devices company that sells a luer-lock compatible mouthpiece, which I'll use for these initial LipSync test units. Those mouthpieces also arrived:
I'm going to leave them in the sealed packaging until they're ready to be installed.
