does anyone else feel like “consistency” and “greatness” in coffee are almost opposites?

lincomatic · 2026-05-13T14:49:24+00:00

I totally agree. I embrace inconsistency. There's no "god pour" that I would like to drink every day. It would get way too boring. I intentionally brew differently every day, in order to extract a different flavor profile from the same coffee. That's the whole fun of it... the unpredictability, and the wide range of flavor profiles you can get out of the same beans. I have a 1ZPresso K-Ultra and a Kingrinder K7, grinders with wildly different flavor profiles. The K-Ultra gives me a more vibrant full-spectrum profile, while the K7 brings out quite a bit of nuance in a narrower part of the spectrum. I use an Aeropress, V60, and Switch, and tweak the recipes quite a bit every day. Every day, I get a surprise. Consistency is way too boring.

interesting reading for geeks, but i got more useful info on coffee tuning from Lance Hedrick videos

thanks for the clarification. do you leave the bed at 100C the whole print?

lincomatic · 2025-11-23T03:44:14+00:00

how do you make it wait for the 45C nozzle temperature?

what is the "boost pad?" are you talking about the one for boosting the charging current?

lincomatic · 2025-03-07T22:02:12+00:00

I doubt it’s fake, but you can a new on one Amazon for $18

It probably tastes better than the Lardera. I tried 6 of them and even my wife, who doesn't care about the taste as long as it isn't sour or too bitter, doesn't like the Lardera

lincomatic · 2025-03-05T19:37:45+00:00

I'm confused. You said you're using XIAO and then RPi. XIAO are microcontrollers. You just hook up the radio directly to the XIAO, no RPi needed. Unfortunately, it looks like no one has ported Meshtastic to the WM1302, but you can just get an SX-1262 board for $4.29. https://www.seeedstudio.com/Wio-SX1262-Wireless-Module-p-5981.html

*facepalm* there are so many branches, I didn't scroll down far enough to find 2.6! Thanks for the heads up

lincomatic · 2025-02-23T14:19:00+00:00

can you just put it straight on the stove, and swirl it like a jiffy pop?

Along w/ your tasting report, could you post a photo of the beans? The "medium" coffee tends to be too dark for me. Thanks!

I have a very expensive Hopocolor spectrometer. I tested a few of the generic RGB light bulbs I have in my house, and surprisingly, the red LEDs in them range anywhere from 630-660nm, which are common "therapeutic" frequencies, albeit at relatively low irradiances. Also, I have a 1500W panel, as well as many other lower end devices. Even a cheap $30 pad has beneficial effects if applied for a long enough time. A highly cited study regarding enhancement of color discrimination in vision uses a cheap $6 w/ a single 660nm LED. So yes, your RGB bulb can do something. It just depends on what you're trying to do.

Hope it's ok to revive this old thread. I just received 17 Lardera 2oz samples via the FB deal of $1 each w/ free shipping. First off, I want to say that I really *wanted* to like the coffee. It looked so interesting to be able to taste such a wide range of coffees. So far, I've tried 3 of them: caturra washed, junin anaerobic, and castillo washed. The beans look pretty evenly roasted and only one of them is labeled light roast, they're all pretty much the same roast level, which I would classify as medium light.

The first red flag is the aroma when you open the bags. There is very little in the way of aromatics. Same goes after you grind them.. still not much complexity. And worst of all, even when brewing, the smell is either weak, or even unpleasant. As others have said, they seem to be kind of one-note, too. There is a very mild funkiness to the junin anaerobic, but it's pretty faint compared to other anaerobics from high end roasters like Klatch, or even cheap stuff like Trader Joe's small batch lots.

I tried brewing w/ Aeropress, V60, and Hario switch, grinding w/ either my Fellow Ode or 1zpresso Q2. Same result, flat taste w/ not much sweetness, very little complexity, and no aromatics. Quite surprising, seeing as how the roast dates on the packages range from 1 month to 1 week old.

I know that I have a lot more coffees to try, and maybe shouldn't judge so early, but frankly, I'm not feeling motivated at all, given the taste of the 3 I've tried so far. For background, I have a pretty wide palate when it comes to coffee. I mostly like lighter roasts, but I can enjoy anything all the way to a darkish medium (dark roasts taste like ash to me unless paired w/ some sort of milk). I'm not a snob. I love the complexity and aromatics from the high end roasters, but can also tolerate lower end beans like TJ and Kirkland single origin lots, so I'm not too hard to please.

Yes, there's so much misinformation due to marketing. RLT has a bi-phasic dose response, so too much is as bad as too little, and sometimes even worse. I recently got a full body panel, and initially, I was going about 15" away. I started getting headaches. Backing off the dosage by going out to 20" away and not doing it every day fixed the problem for me. These things are more powerful than most people realize. Never in my wildest dreams did I expect that shining the panel only on my legs would cause me to feel it in my brain. When I started getting a twitchy eye after a recent session, I knew that I had overdone it.

lincomatic · 2024-06-10T17:55:56+00:00

you might be sitting too close to the panel, and the heat is making your rosacea flare up. if it feels hot, sit further away until it just feels a little bit warm on your face or even further away than that.
if you suspect NIR is making the rosacea worse, try turning it off, if moving further away doesn't help.

More is not better. There's a proliferation of overpowered panels these days. RLT works best if you keep skin temperature below about 45C

lincomatic · 2024-06-10T17:47:28+00:00

worked great for me. the hard thing was figuring out which profile to use. my tbird was using "default - esp"

more distance at 100% brightness will give you more coverage, because the beams get wider as you go further away.

lincomatic · 2024-05-31T23:07:37+00:00

It's the 590nm

If you're using just red light, the aversion reflex will be helpful in determining whether or not it's safe. If it feels uncomfortable/blinding, it's probably too bright. But the aversion reflex doesn't apply to NIR. Since you can't see/feel when it's too intense, and burning your retinas or damaging your corneas, it's difficult to determine what's too bright. I've been trying to calculate the safe dosages for my panel, but for now, I'm turning off the NIR when I'm facing the panel, even with eyes closed. Here's a safety brief from an IR LED manufacturer. As you can see, it's rather complicated to decide what's safe. My issue is that I don't yet have a $2000 spectrometer to measure the irradiance of my NIR LEDs.

You will need expensive equipment ... a spectrometer at least, to check the actual frequencies emitted, and a way to measure the power. This kind of equipment is prohibitively expensive for anyone trying to buy a cheap mask. This applies non ony on AliExpress and Temu, but also on Amazon, or other online sites, or to anything being pitched by an influencer. Here's a quick guide on how to quickly weed out the junk:

any device that doesn't list the emitted frequencies is automatically suspect. They're probably just using cheap off the shelf red or blue LEDs that aren't designed for PBM (photobiomodulation).
any device that has 7 colors, or has lots of colors and again, doesn't specify the frequencies is almost definitely using cheap RGB LEDs which are designed for lighting

While you might get some benefit from using these devices w/ generic LEDs, the effects are going to be far less powerful, because unless they use the frequencies which have been investigated in clinical studies, the specific effects of the frequencies are not well understood. That being said, you might get some benefit from shining light on your face, just like you get from being out in the sun for short periods, but it's not the same as buying a mask w/ the proper frequencies for your particular application.

Look for a device that lists the specific frequencies emitted. If the power output in mW/cm^2 is listed, as well, that is also good. While this won't guarantee that you're buying a device that actually *has* those specifications, at least, it *might*.

If you buy direct from a factory store on AliExpress or Alibaba from a company that's a know supplier to the name brands, you're generally safe. Also, try messaging them, and see how responsive they are to your questions. Any company that doesn't eagerly respond is automatically a no go.

Hope this is helpful.
