One of my customers approached me a few weeks ago about a project to replace the sealed lead acid battery (now unobtainium) in Tek 222/224 scopes with lithium ion cells that presumably will continue to be available for the foreseeable future. He pointed me to a really well done project with a public domain license. There's a YouTube video on it - https://youtu.be/LJ2VS3aohV0.
After a couple of weeks of capturing schematics, sourcing parts, etc. I'm about ready to hit Send on an order for the PCBs. Before I do that, however, I wanted to check with the community to see if there's sufficient interest to order more than the minimum quantity of boards.
How about it, Tek 222/224 collectors? Any interest in a battery pack replacement based on the design in the YouTube video above?

Definitely interested. I bought a 222 to add to my collection, but it’s turned out to be surprisingly useful. I’d like to replace the dud lead-acid battery but the usual replacements involve cutting the case, which I’m reluctant to do. I think the YouTube video approach doesn’t cut the case?
I didn’t watch the whole thing, admittedly.
Either way, I’m definitely interested in a board. I’m in the UK, so I don’t know if shipping might be an issue though I guess a board should fit in an envelope.
