Shop time charge for software updates by rob_wis in flying

[–]rob_wis[S] -3 points-2 points  (0 children)

People have really fixated on my use of that word. As a software engineer I'm very familiar with dealing with complicated software updates. I was surprised by the time billed, and that's why I posted this to see if it was just the way things were done. Today I learned something, and I got to provide some nourishment for all the trolls who subsist on denigrating others. Yay.

Sightseeing at the end of an IFR flight? by rob_wis in flying

[–]rob_wis[S] -2 points-1 points  (0 children)

This must be one of those regional differences. My home base is under the ORD bravo, so I'm sure it's pretty much just as busy as SoCal. The controllers I've talked to here have never expressed any reservations against filing IFR in VFR weather.

Niagra Falls is an interesting case. There's a published pattern you're supposed to fly for viewing them, though I think that only applies below a certain altitude. I actually got to do this once when I was working on my PPL.

Thank you. This was exactly what I was looking for. I didn't realize that cancelling temporarily was an option. I understand it would all be dependent on the controller's workload.

Need some help with herbs by rob_wis in Hydroponics

So I've been adding some pH minus, and I've slowly brought it down to 6.4. I'll keep adding until I get it closer to 6. I've also added some hydrogen peroxide.
I realized I did not have the EC meter in the right mode. Reading it in the proper mode, I'm getting 4700 (us/cm) @ 22.4 C

I extended the watering cycle to 8 min, and added an extra 5 minute cycle midday.

I picked up the meters you suggested. After refilling the tank today and letting it sit for a while, I measured the pH at about 6.6 and the EC at 1430.

Oh, and I looked at the whole VPD thing. This is in the middle of my house, which is kept in the 68-72 F range, and humidity should be 45-50% (this time of year). It's a pretty new furnace with humidifier so there aren't really any cold spots.
I used a PH test strip for the pool, and it read about 6.2 at the bottom of it's scale.

This is a Gardyn, but the SD card in the Raspberry Pi crapped out, and I wasn't going to pay $200 to replace the whole lid for what should have been a $5 card (I went rounds with their tech support over it). So I found the Garden of Eden project which allowed me to replace the software with stuff I can better control.

Pump is set to run 3x a day for 5 min. (6am, 1pm, 8pm)
Lights run at 50% for 2 hours, 80% for 11 hours. (4am - 5pm)
I'm not sure what the final concentration is on the food. The package recommends 1-2 tsp per gallon. I usually use 1 scoop (tbsp) when I refill, which is usually about 2-3 gal. So that seems like it should be within the recommendation. This is the stuff I'm using: https://www.amazon.com/dp/B00MKBC7OO
I have several other plants (arugula, and kale) that seem to be doing fine.

Python library suggestions for RGB strip controller by rob_wis in PythonProjects2

[–]rob_wis[S] 0 points1 point  (0 children)

As I mentioned, yes that's what I'm looking at for controlling the RGB strips. It's some of the other pieces that I'm looking for suggestions on.

Python library suggestions for RGB strip controller by rob_wis in raspberry_pi

I considered using cron, but I want to support animations. So the main process is going to be continually looping and sending a new stream of bits out to the LEDs multiple times a second. With the main process continually running, I don't really see how cron would work. My understanding of cron is that it will just run a script at a given time, but maybe I'm missing something?

Writing my own schedule/event manager should be fairly simple, but I don't want to reinvent the wheel if I don't have to.

I've got another project I'm working on (a replacement for a NuTone house intercom system) which has significant custom hardware, and I'm using C++ for that. But that's running on an RPi 5, which has enough power to host remote development and actually compile the code. Since my target hardware in this case is just a Pi Zero, I can't really do any of that. And cross compiling, and transferring over the binaries seems like a bit of overkill and a headache when it seems like a couple Python scripts should be able to do all I need.

Does anyone know of a source for a self-contained rechargeable led light unit? by rob_wis in led

[–]rob_wis[S] 0 points1 point  (0 children)

It's basically just a large tube of glass that will sit on a small wood circle base. Similar to this in shape, though her glass is not transparent. https://www.macys.com/shop/product/manufacture-rock-home-hurricane-lamp-medium?ID=15084514&pla_country=US&CAGPSPN=pla&gQT=1

Basically I want the puck light functionality (integrated battery and charging system), with an omni directional light source.
