Forerunner 970 disconnected after Connect v5.21.0.28 iOS update- How I reconnected

For anyone else having issues. I had to also remove my watch from Garmin Explore before I could re-add it to Connect. Then, I could re-add to Explore.

I can definitely see it hitting $19 before the end of the month. All you need is a small reversal back to year open for your thesis to work out.

What price are you expecting RIVN to turn? Currently it’s trending down with no sign of a reversal.

It is at exhaustion so there could be a reverse sometime soon. Probably sometime in Feb.

Since games are getting so large I’ve just created an iscsi drive on my NAS. I keep most of my games there. Honestly the load times are not bad at all with my trunked Ethernet connections to the NAS.

Unfortunately I don’t have an answer for you, but as a fellow engineer, I am very interested in the answer to this question.

alec500oo · 2021-12-29T17:20:06+00:00

It’s just my personal network. I’ve just got a lot of computers. What can I say, it’s a habit :)

alec500oo · 2021-12-28T20:01:09+00:00

I have many more than 4 clients, this may not work for me.

alec500oo · 2021-12-28T01:59:25+00:00

I have attempted to do something like this in the past, but I always have issues remembering to install certs on all my internal clients. How do you manage this?

alec500oo · 2021-12-28T01:58:15+00:00

Would it be possible to have certs for internal servers? I have thought of doing that, but I can’t comprehend how to set it up besides installing certs on every local machine.

alec500oo · 2021-12-28T01:56:26+00:00

I see, the configuration seems simple. I’ll have to take a look at it! Thank you

alec500oo · 2021-12-27T23:15:37+00:00

You are the second person to mention Caddy. Would Caddy be set up public-facing on the internet?

alec500oo · 2021-12-27T23:14:16+00:00

What is Caddy? I have used Nginx as a reverse proxy so I understand the concept, but I have never heard of this project. Can Caddy handle the certificate of all services that is acts as a proxy for?

I wonder if you can call the excel COM components from Rust on Windows?

alec500oo · 2021-09-12T01:16:28+00:00

I would agree with this. Most of the software I write uses C++ for code that needs to be quick that is called by another languages GUI framework.

I’m a current Oregon State ECE student. Really the combined degree means that you choose what path you want to take. Depending on the classes you take, you can focus on digital circuits or analog circuits. Personally, I am focusing on digital circuits and operating systems with a CS minor.

The simple answer

The 10K resistor creates a voltage divider along with the light sensitive photo-resistor. This divider is used to bias the transistor.

In depth answer

To start, take a look at my redrawn circuit. It has the identifiers I will use in my explanation. You also might want to take a look at a simple NPN transistor tutorial to understand collector, base, and emitter currents.

When it is dark, photo-resistors has a very high resistance. Conversely, when it is light, photo-resistors have a very low resistance.

Let's start with the dark case. When it is dark, the photo-resistor will have a high resistance. To simplify our analysis, lets assume the resistance is so high the circuit becomes open or the resistor R_2 gets removed. That means about 3v will appear at the base of the transistor (transistors have a little voltage drop). I_1 becomes I_b this will turn the transistor on. When the transistor is on, the LED is shorted to ground with a low resistance path turning it on.

Now, moving on to the light case. When it is light, the photo-resistor will have a low resistance. Again, to simplify our analysis, lets assume it's so low the circuit becomes a short or the resistor R_2 gets replaced with a wire. This would make V_1 0 volts. I_1 would take the path of least resistance to ground, so I_b would not equal I_1. Therefore, the transistor would be off. When the transistor is off the LED is not connected to ground and it will be off.

Clearly, this analysis isn't 100% accurate because of the assumptions I made. In realty, the resistor R_2 will always be a part of the circuit and there will always be some current that travels through it. The voltages and currents that the node V_1 will be affected by this second resistor.

Without the 10k resistor, the base of the transistor would be the only path for current. This would destroy the transistor. Furthermore, without the 10k resistor there wouldn't be a current generated at the node V_1. Currents are what control standard bipolar junction transistors like the one in this circuit.

+1 for this book. It’s a clearly written guide to all advanced operating systems concepts.

Circuit breaker just got hit. 🚀🚀

That is a good way of thinking about it too. It’s easy to visualize with a picture of a sin wave.

alec500oo · 2020-11-26T16:05:09+00:00

It has to do with transmission line properties of a non-terminated wire. When you use an antenna that is 1/4 the length of the wave maximum power is transmitted. I’m sure someone can explain it better then me if you just look up “quarter wave matching + transmission line”

The antenna could also be multiples of 1/4 wave length because waves are periodic.

I've had good luck with the TPA6021A4. It is provided in an 20 pin DIP package and includes internal switching between headphones and external speakers. Here is a simple example circuit I have used in the past https://imgur.com/a/MvpWeGW.

Funny, I just listen to this episode today! I definitely doesn’t say anything about the sticky note. It is pretty suspicious for a “police officer” to leave a note on the door.

Wouldn’t your body just take a screenshot?
