    Israel bombed Iranian Embassy

    About Hunter Biden's laptop. The FBI never had that laptop, only a cloned hard drive full of very obviously edited materiel.

    Space Discussion Thread

    Why? It was the most expensive ride to orbit ever. What was the maximum # of launches/year? It started out as a pretty decent design, then the military stuck their thumbs in the pie and cut it's capabilities in half.

    Man those grocery store prices are high.

    My wife and I have some horseradish that's been growing untouched in our garden for 11 years. Should be plenty warm by now ;-)

    Low voltage, HC driver for a coherent FAP module?

    Buck converter was pretty much what I had in mind. Maybe parallel a couple of VRMs used for CPUs? Would take a custom PCB but would be pretty efficient. My motherboard can feed my CPU well over 100A @ 1.25 volts so they could handle the load.

    Low voltage, HC driver for a coherent FAP module?

    A linear regulator for this current @ only a couple volts is gonna generate a lotta heat. Well over 100 watts if you start with a 5V power supply. A switching regulator would be more complex but a lot more efficient.

    IR is cheap.

    UV Lasers

    Quite the bargain @ only $3200 for the 5 watt unit. But again, these are pulsed instead of CW.

    Cute lil' thing. Wonder how the cost of throwing one of those away compares with reusable rockets from spaceX.

    Man those grocery store prices are high.

    You can try carbonating tea but don't add any sugar before adding the fizz. The SodaStream instructions emphasize carbonating ONLY water; no flavorings or additives. I tried fizzing up a bottle with some of that Mio flavoring in it.....mistake. As soon as I unscrewed the bottle from the...

    Man those grocery store prices are high.

    Soda Stream is cool but the pressure isn't adjustable. For maximum fizzy I put the bottle of flat water in the freezer and get it as cold as I can without freezing before carbonation. Cold water will hold more Co2 in solution.

    Surprisingly hard to find 555, 573nm goggles

    $$ ouch. But of course, what are your eyes worth?

    https://www.survivallaserusa.com/Eagle_Pair__190-400nm___560-640nm_Laser_Safety_Goggles/p1667092_12825348.aspx 555 is right at the edge for these, but they cover 573.

    Man those grocery store prices are high.

    Metformin=glucophage. Dr. has me on glipizide too. Working pretty well so far. I only test once daily @ this point and my morning sugar is usually ~100. Things got outta hand back in November. Reported to the ER (eyes wouldn't focus) with my sugar @ 400+. Found out type II is one o' those...

    L.A.S.E.R., a word, or an abbreviation?

    It also doesn't help when they get the words making up the acronym wrong. Demerits for "Amplified" and "Stimulating"

    Am I slowly damaging my eyes using my burning laser pointer without glasses?

    "An increasing number of studies has revealed that long-term blue light (400–500 nm) exposure induces oxidative stress in the retina and causes severe damage to retinal tissues, especially RPE cells [13,14], with harmful effects peaking at 440 nm [15,16]."

    A huge group of idiots

    I think you meant ....clearly says it WAS in Mexico. From the headline of the article: Shocking video footage from a fireworks event in Tultepec, Mexico, shows a huge crowd targeting the aircraft as it flies above.
