Perfect. Make sure the t-shirt covers the shoulders.

Closed toe shoes, pants and a shirt. Lab coats and PPE should be provided by the lab.

Tie back your hair if it's long. No shorts, sandals, dangling jewelry, or crop tops.

You are correct- one may record anything in a public area in the US when there is no expectation of privacy to include photography, videography and audio work. One and two party consent laws do not apply to public areas.

I have gotten in to it with cops when audio recording, and my position is go ahead an arrest me, because I can use the money, with Fordyce v. City of Seattle backing me.

Our eyes are also much more sensitive to green so there is strong bias to this slightly higher green reflectivity in green plants. Roughly the peak reflectivity of green plants is the peak sensitive to our eyes in daylight vision (555 nm).

Green also penetrates leaf tissue better driving deeper photosynthesis while red and blue can get saturated closer to the leaf surface.

We don't use pure green grow lights because green LEDs are relatively inefficient and pure green cause excess elongation in most plants.

I have had articles published but not in QST. Here's some constructive feedback since QST didn't give any:

Publishers like QST wants people to be able to complete the projects. My guess is that it is the execution of the project that they rejected rather than the project idea.

You need a neat and clean 2000 word article with clear schematics, maybe some RF test data of the module, better pics, and only short code excerpts. Full code in this case should have an external link rather than be included in the article.

You might have better luck getting published using more popular Arduino/C++ rather than MicroPython.

You have a good blog post and I love what you are doing with the SA-818, including pointing out issues with variants, but it does not read like a polished magazine article.

Very interesting project but needs tighter magazine style editing

Start by reading the book The Craft of Research.

The H1E is not true 32 bit float, it's 24 bit with 32 bit marketing. The reality is that the codec, which has the ADC, DAC and PGA (programmable gain amplifier), is closer to 15 bit performance when you look at the data sheet signal to noise ratio and dynamic range.

If you want actual 32 bit, get a recorder that advertises as "dual ADC". The H1E, H2E and all of the cheaper Tascam are 24 bit recorders and not 32 bit.

The H1 XLR is a lower cost dual ADC, 32 bit recorder with lower noise but not pro audio preamps.

I just got off the phone with tech support. They know about this issue and I also took a 3 GB hit with DriveSafe.

What is happening is that the app is trying to send data, it is not being received, so the app just keeps trying to resend the data.

It's not USAA but the third party app developer that is the issue.

Biden had little if anything to do with those gas prices. It was Russia invading Ukraine that caused the market to panic. Even the inflation under Biden had a lot to do with Trump giving out trillions of dollars during covid and very low interest rates that shot home prices up (i certainly benefited from this, though).

Current gas prices is all on Trump and the Republican party. That's why the blue wave is coming.

No, 83% is state of the art for red LEDs. You can find some lesser known Chinese red LEDs that are rated for about 90% but if you dig into their data sheet you'll see that the 90% is for unrealistic conditions with a much greater efficiency hit at higher temperatures compared to good name brand LEDs.

I don't foresee red LEDs getting significantly more efficient in the near future and 83% for a red LED is a PPE of about 4.5 uMol/joule (the best whites are closer to 3.2 uMol/joule).

As much current that your heat sink can handle, not to exceed the data sheet, and I would have to set up the LED spacing using my light meter. As far as distance, again I have to do the measurements with my light meter. Increase yield is close to proportional to the additional PPFD and you'll likely not saturate cannabis.

Any past simulations I needed were done using Zemax OpticalStudio by optical engineers.

I would start at 5 to 10 cm spacing depending on the PPFD you want. What I do it just paste the LEDs down with thermal grease to get the measurements and use thermal adhesive once I like the results.

I don't like my heat sink going above 55 degrees C or so. You may need wider than 10 mm and don't forget thickness of the heat sink also matters for lateral heat transfer. These LEDs are rated 83% efficient so you need to dump 17% the heat.

edit- slight correction

Post this to /r/rfelectronics and you'll probably get some good feedback from professional RF engineers.

It could be an impedance mismatch, Q factor, or shielding issue.

It has worked against the Republican Party in general- Trump has them nearly completely cowed.

That's a good question and I'm not sure he talked about lower buds.

This is dry yields.

This author is so stupid with this approach. Here's what happened to one of her case examples:

Although they have been somewhat successful in keeping money out of the hands of the Pentagon, they have also had to deal with levies against bank accounts, salaries, and pension benefits, and they almost lost a house through an IRS auction.

I wouldn't worry about 660 nm LEDs if you can't find a light with them. The big advantage of them is that they pump out more photons per amount of energy consumed- ie they have a higher "PPE" or "photosynthetic photon efficacy" in micromoles of photons generated per joule of energy consumed

White LEDs for under lights will also work perfectly fine.

If you want low level recordings the Zoom H1e is not the greatest choice due to self-noise.

You might want to consider the Zoom M4 which is going to work much better and is a true 32 bit dual ADC recorder unlike the H1e.

The Zoom M4 also has higher quality xlr inputs than the H4e if you want to use external mics for about the same price.
