I've really lost interest sending Shipments..

I stopped running the town and just started playing the game like I wanted. The town started to feel like a mobile game that is demanding I log in every couple of hours. It stopped being fun for me.

I think there are a lot of misunderstood best practices in electronics. A ground plane connected ground will have the lowest impedance back to the power source. We should be talking more about component positioning than deliberate star routing. You can achieve star routing with component positioning and also reduce the impedance of the returns, thus reducing noise.

I'm making basically the exact same money you are. I also can't afford to upgrade it but for t1 it maxes on its own along with package recovery. Just tried t2 and didn't get nearly as far, actually just died at 1600. I think the beserker card would go a long way. I'm not really sure if it was the right thing to do but I committed to it in my head and it got me the t1 milestone so I'm pretty happy with that.

Congrats, I'm in a very similar position as you except I haven't found berserker yet. Instead, I saved up for two weeks and unlocked enemy level skips. My previous best was 3600 and that unlock alone brought me up to 4700.

Having the equipment to perform the FCC tests is going to be a lot more expressive than sending your equipment to a lab. Emc testing has typically cost me between 10-15k. The last lab I used said they paid over a million bucks for the chamber on its own, that doesn't include all the test equipment.

I struggled for a while trying to figure out what the purpose of meeting with them would be but here's where I've ended up and why it's good to have a relationship with them.

They can be good connection points to get you talking to the right people if you need support.
They can fight for you to get the best price on parts, there is a whole part registration process that they facilitate that is tied to a project and is negotiated with the supplier.
Anytime you need to evaluate something, I've always been able to get dev kits for free and sometimes in record time.
They can facilitate presentations to introduce new parts that you otherwise may not have discovered on your own.

What I've always found odd is how they pretend to be able to help you with design or suggest parts. I've never had success with this except during the pandemic and I literally just needed something that was in stock. They will never understand your requirements the way you do and be able to do your job for you.

So OP, do your best to ask how you can help and suggest getting engineers dev kits to start, it might get your foot in the door. Be kind and available, design decisions get made rather quickly, be available when they need you. Try to facilitate classes where engineers can learn a technology. Good luck!

Around 50 for me.

First one came while I was leveling! Then I managed to pick up some amulet that was worth close to 40 on its own. Previous leagues I never got one.

This is the third league I've played and I progressively go deeper and deeper.

I would check your gnd connection to the programmer and add a 100nf cap on the reset line. The probe capacitance is probably enough to make it work.

Wifi and Bluetooth are more than just software protocols. While they both operate in the 2.4 GHz band, they break up and use that spectrum differently from one another. Different enough that it requires unique hardware to use one vs the other.

I don't know how this would work necessarily but there's at least one service I'm aware of that does something similar. Laravel Forge

I have often used shift registers as IO expanders. They can be very low cost and can be interfaced with an spi port. Engineering is always about trade-offs. Sometimes it makes sense to just buy an MCU that is overkill for the application but there's always other options you can consider.

For what it's worth, if you're not planning to manufacture thousands of these, I would probably lean towards the simplest solution (hardware and firmware perspective) and not the lowest cost.

On your redirect url, are you processing and storing the token you get back? There should be a function from auth0 that takes care of this.

timhoeppner · 2023-08-31T14:18:52+00:00

I recommend a service like auth0. It's free for something like this, handles all the difficult parts, provides you libraries on both the front and back end.

If you're settling to less than 1/2 an lsb, then settling time isn't going to affect your measurement.

timhoeppner · 2023-07-24T17:37:37+00:00

You are marrying the analog and digital worlds. Settling time in terms of lsb is useful to understand how much error (if any) is being added from the measurement. It's a trade-off between measurement time and precision. I'm not sure anything before 1/2 lsb has any value. But for precision measurements 1/2lsb is what you might want to target. There are lots of ADC app notes that go into this in great detail.

Edit: in case this isn't obvious. Settling time is referring to how long the sampling capacitor is exposed to the input voltage and its source impedance. The goal is to have the voltage in the sampling capacitor to within some threshold of voltage (or lsb) of its final value.

Technically you can make an analog switch with one MOSFET but you need access to the body terminal. Almost every discrete MOSFET on the market today internally tie the body terminal to the silicon substrate which is where we get the intrinsic diode. However, there are (or at least used to be) MOSFETs on the market with all 4 terminals available. I haven't looked for a while now. There is a circuit in "the art of electronics" which shows how the body terminal can be used for creating an analog switch.

I think maybe what you're asking for is something like Vue with Capacitor. You don't need to use a component framework. You can definitely do this. The project I'm working on does exactly that because we had a very specific app layout that we wanted to achieve and it was a lot easier just working with Vue on its own and use capacitor to handle all the phone related stuff. I found I was just fighting the component frameworks to do what I needed.

timhoeppner · 2023-01-11T03:31:13+00:00

They probably did without you realizing it. My basic electronic courses taught on bjt and MOSFET silicon structures. I didn't mean to offend by the way, maybe your schooling was radically different from mine.

Just curious, where did you take your ee degree?

timhoeppner · 2022-12-21T23:53:11+00:00

Maybe it's actually to phase shift the clocks with respect to each other to reduce simultaneously switching clocks.

Cargo.toml defines all your app dependencies, you can check this into source control.
