Yeah I saw those just checking if it had been via Algolia, but they didn't do very well and I thought an actual 'Show HN' that's clearly a 'member project' as it were, with someone around to answer questions and chat about it, might fare better. (The call for feedback a couple of years ago aside.) Plenty of interest in this thread despite no relation (in terms of the product) to OP! And people seem often to be commenting about these things, or difficulty in buying big/good enough epaper displays to do it, etc.
