Thanks. Don't know what happened:

Intended to comment on

"Show HN: HN Update – Hourly News Broadcast of Top HN Stories (hnup.date)"

at

https://news.ycombinator.com/item?id=41893524

but apparently somehow posted to

"3D-Printed Active Electronics (news.mit.edu)"

at

https://news.ycombinator.com/item?id=41893524

Just deleted the post at

"3D-Printed Active Electronics (news.mit.edu)"

and submitted the post to

"Show HN: HN Update – Hourly News Broadcast of Top HN Stories (hnup.date)"

Thanks.
