One of the unfortunate things about Hackaday’s globe-spanning empire is that you often don’t get to meet the people you work with in person. Since I was in China and it’s right next door, I really wanted to pop over to Vietnam and meet Sean Boyce, who has been writing for Hackaday for a couple of years, yet we’ve never met. I suggested we could make this happen if we put together a meetup or unconference. Sean was immediately confident that the Ho Chi Minh City hardware hackers would turn out in force and boy was he right! On Sunday night we had a full house for the first ever Hackaday Vietnam Meetup.
Join Sean and Mike at Trung Nguyên Legend Café from 7-10 pm on Sunday, March 24th for a bring-a-hack style meetup. If you have a hardware project you’ve been working on, come and show it off as an excellent conversation starter. If not, that’s fine too. We’ve also lined up three short talks spanning topics from robotics to analog electronics. Of course if you’re excited about giving a talk, let us know in the comments below and we’ll work on squeezing you in.
Hackaday tries to host live events in all corners of the world, and it’s exciting to add Vietnam to the list. Head on over to the event page for more info, and we look forward to seeing you there! Of course if you happen to be on the other side of the world this coming weekend, there’s a Hackaday Mini-Unconference happening in Cambridge, UK!
Have you ever thought about coffee purity? It’s more something you’d encounter with prescription or elicit drugs, but coffee is actually a rather valuable commodity. If a seller can make the actual grounds go a bit further by stretching the brew with alternative ingredients there becomes an incentive to cheat.
If this sounds like the stuff rumors are made of, that’s because it is! Here in Ho Chi Minh City there are age-old rumors a coffee syndicate that masterfully passes off adulterated product as pure, high-grade coffee. Rumors are one thing, but the local media started picking up on these suspicions and that caught my attention. I decided to look to simple chemistry to see if I could prove or disprove the story.
What we want to investigate is whether price and coffee purity are related. If they are, then after accounting for the effect of price, we will want to know whether proximity to the market where artificial coffee flavoring is sold has an effect on coffee purity.
