  • Hmm. I did find it in the OsmAnd app, but I’m very confused. I think it’s just showing me trip durations, not actual schedules, and definitely not live bus data, nor any option to find routes based on a specific departure or arrival time. For the route I tested, it gave me 4 different options, all of which list a departure time of 0:00, even though it’s early afternoon here.

    Digging around the other apps I use, it looks like the live transit data that I’m used to is free to access. Is there something I need to do to get that linked up?







  • Definitely in agreement that the cost of caffeine is a non-factor in the cost of energy drinks vs. other soft drinks.

    I don’t believe Sigma Aldrich sells to the general public though, do they?

    Personally, I prefer the loose powder vs. preportioned capsules or pills, since it allows me easier control over the dose. When I use caffeine powder, I usually mix it into a drink and just sip on it, rather than take it all at once. Sometimes I just want some herbal tea or a sparkling water with a little extra caffeine… I want the caffeine of coffee or energy drinks, but I don’t want the flavor. Way back in the day, I’d add about 200mg caffeine to a 1L bottle of water and sip on that until it was about halfway gone, then top it off with more water to dilute the remaining caffeine.







  • If you can get ahold of it, yes, very cheap. The problem is that a little goes a very long way, so it’s not so easy to get a hold of anymore, at least in the US.

    It was probably 10 years ago that I discovered that I could buy a 500g bag of pure caffeine powder for about $20, plus a milligram scale for another $20. I was drinking quite a bit of sugar free Red Bull at the time, and had been ordering them by the case ($50ish?) to save a little money, so it was a no brainer for me to switch to caffeine powder. Break even point was maybe 2 weeks worth of caffeinated beverages.

    The bad news is a few people OD’d on caffeine powder around that time (completely unrelated to me), so it was pretty much banned. The good news is that 500g is a fucking shit load of caffeine. I often get my caffeine from more traditional sources now (coffee, tea), so that bag may end up lasting me the rest of my life.

    For some additional context, a 250mL (8.4 oz) can of Red Bull contains 80mg caffeine, while a 1/16 teaspoon (~0.3mL) scoop of pure caffeine powder is about 200mg. That works out to less than 0.5¢ ($0.005) of caffeine per Red Bull, and I’m not even getting wholesale pricing.
