Lorraine Underwood<p>Is Hackaday Europe every year? 🤔 I want to build a badge add on! I've already got ideas... <a href="https://mastodon.social/tags/hackadayeurope" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>hackadayeurope</span></a></p>
Matthijs Kooijman<p>Did some more hacking on our dismantled EV charger at <a href="https://fosstodon.org/tags/HackadayEurope" class="mention hashtag" rel="tag">#<span>HackadayEurope</span></a> today (while watching a lot of cool presentation).</p><p>We tried to get the tangle of charger parts we brought into a functional state (at least let the software think it is functional). So we made a small PCB to emulate a cable and car, faked the kwh meter using python, connected some 230V to the right places, but still kept complaining about a "Phase error". Out of options for today, but happy with the progress we made :-)</p>
