High pressure, high forces, long lever arms...all of that meant heavy and strong (read: expensive) parts which I was not looking forward to having to fabricate. Instead, I settled on the simpler idea of harnessing the power of compressed gas. Instead of using a high mechanical advantage lever to push a piston, compressed CO2...
I think part of the appeal of the espresso maker this guy DIYed is that it has no pump/electrical components. Less points of failure and cheaper to make, cost seems to be a driving factor in his design. A bike pump is a fairly common thing for someone to own.
It would be really cool if you could use a compressed air tank that you can recharge with a bike pump. Something like this has a max of 200psi and is refillable with a shrader valve. More upfront cost but but you don’t have to buy CO2 cartridges.
Great news everyone! Hopefully the system works well and other cities will follow suit. I know in the USA (in the few places we do have public transit) the argument for keeping fares is always 1.we don’t want to pay taxes for that and 2.if we charge that’ll keep the vagrants from using it. Two arguments that make no sense at all, 1. We already pay taxes for the public transit, why pay more to actually use it? And 2.anyone who has used public transit knows the fare doesn’t keep vagrants out.
Plus you can’t leave it parked anywhere. Anyone who sees it will want to recreate the famous steel ball test. Dude will spend a fortune at the tesla dealership getting his “bulletproof” windows replaced every week.
I just got my package of new earphones from Best Buy, and the box was fucking empty. I mean there is the box and instruction manuals and charging cable, but the actual earphones aren’t there. They’ve used Shipt (which is like a doordash but for packages) but the box was inside another layer of packaging which was supposedly...
A few weeks ago I shipped a package USPS and I wanted to track it’s progress. I googled USPS tracking and clicked on the first link that popped up. The search result looked like the USPS website and said USPS .com and had the same preview text that the actual website used but it was actually a Google ad that redirected me to supertracking .com. This fake website looked exactly like the USPS tracking website, the domain the web browser displayed was wrong but everything on the page was right, the buttons on the bottom and top even sent you back to the official USPS site. The fake site was set up so that no matter what you entered it would say the address was wrong and you had to update it for a $1.50 address update fee. I would have grown suspicious here except I actually did put the wrong zip code down when I shipped it. Again all the forms looked legit so I put my credit card info in after updating the address, then it wanted me to confirm my bank account login and pin. This is where I stopped because there is no reason for them to collect that data. I saw it was the wrong website and looked back in my history and sure enough I clicked on an ad without realizing it. I reported the domain, reported the ad, and cancelled my credit card. It was really scary how real the website felt, I didn’t suspect anything until they wanted bank info.

Have you ever gotten scammed, package stolen, or been a victim of fraud in any way?
