$30 USD for the Meditation module and $120 for all of the modules

I’ve only taken the Meditation guide though. Not sure about the quality of the others.

That's exactly what I've done. Now I'm using the 3.3V pin.

Let em break stuff, an RPi is $35. Better to screw around a get a proof of concept super fast and then get details when you face a problem. Otherwise you end up reading a 500 page data sheet, in which you won’t retain 90% of the information

@@dylpickle8147 page 8 of the rpi datasheet - took me more time to type “raspberry pi datasheet” than to find the pin voltage tolerance table. If one of my junior engineers made this mistake they would have been put on BOM management projects for the next year.

Chill. Stuff like this even happens to seasoned electrical engineers once in a while. Not too long ago, I worked on a project with an electrical engineer with 20+ years of experience and the exact same thing happened, 5V was connected to 3.3V. It still worked, but we did catch it in a review before series production started. A lot of 3.3V pins can tolerate 5V for exactly this reason, you don't want to have your CPU destroyed just because someone mixed up two super common voltages.

I definitely am a tinkerer. I have no background in electrical engineering and this project is entirely for fun. In fact, the main motivation is that I have no experience so each step has been a fun challenge. This particular mistake was caught because I was reading more about the equipment. But yes, going forward, I will probably read the specs in more detail before using new equipment.

Maybe even a limit switch would be better than the fsr.

I initially was using a load cell but switched over to using FSRs. I'm not familiar with multiplexing. I will definitely do research into this before completing the next step. Thanks for the suggestions.

@@scottmacchia in my experience FSR aren’t great unless you have perfect contact. Plus you don’t really care about for you care if a cup is there. I would set up limit switches or photo resistors and then multiplex through them to see what’s occupied.

I've learned a lot about his setup from just watching his streams. I'm not sure if he has a public list of equipment that he uses though.

The API that I use for the hockey data also has EPL data: rapidapi.com/apidojo/api/livescore6 The free tier allows you to make 500 requests per month. I pay for the 50,000 request version just because my app is updating the live scores every 50 seconds. However, it sounds like the 500 requests would be enough for you right now. Currently, my Chrome extension relies on a NodeJS server I built which pulls data from the external API I linked above and stores it in MongoDB. Then, my Chrome extension JS will call the Node server's endpoints to get data. The logic in these endpoints pulls the data from the database. Chrome extensions are actually really easy to build. There are just collections of HTML, CSS, and JS files. This tutorial is a good place to start: developer.chrome.com/docs/extensions/get-started/tutorial/hello-world Additionally, I've actually just started streaming my Chrome extension development here and on Twitch. I can't share the repo since it has some private API keys but in the VODs, you can see most of the code.

To summarize, doing your project as a Chrome extension makes a lot of sense since it's really just a mini website. You can even build the project in such a way that it serves as both a "full" website and a Chrome extension. Adding CSS that is dependent on page width makes this very possible.

That’s how all senior devs work for sure

So now what do you still use the text editor part of VS Code for?

Super new to streaming so the audio was definitely not configured correctly. I will make sure to have it fixed for the next stream :/

@@scottmacchia you are welcome. Happy streaming 😊

That’s definitely true. In fact, I don’t plan to use most of the tools mentioned in the course (ex: Ansible, Dvorak keyboard, dotfiles management). However, for the tools I have adopted, the hope is that time is saved in long run even though it will cost me some time now.

XKCD 1205 - Is it worth the time? 😂

only you can tell, are you in a state where you are bored of your current job and current project and have free time to invest into this time sink. There is profit in the long-run and make it personalized to motivate you to work if its draining@@RT-.

​@@scottmacchia iirc he doesn't recommend dvorak and says he wouldn't have switched to it if he was deciding right now, he only did it for medical reasons but then discovered it was not necessary

@DMSBrian24 Ah interesting. You are correct that he does not explicitly recommend it in the course. I’ve not heard him talk about why he uses it. I’ll have to check that out

Nice. I’ll probably still be using Windows for at least as long as I work for Microsoft. But it’s nice to have WSL as an option

I only found out about Prime last year. I wish I heard some of his advice earlier in my career but later is better than never.

What editor / ide ?

I’m probably a bad judge of my own voice but I can’t hear the similarity :/

Perfect timing! Have you taken his other courses?

@@scottmacchia I'm half way through "The Last Algorithms Course You'll Need" and I really enjoy it. I'm currently in the process of switching to QWERTY from my german layout and while I'm at it I'm also properly learning touch-typing instead of my freestyle technique. As I'm not yet at my regular typing speed this makes coding a lot less enjoyable but it helps me in my path of learning vim later this year with proper muscle memory.

Why switch away from QWERTZ to QWERTY?

Say u swear that’s satire? Really? Was the course bad or something?

The circuit was inspired by this article: core-electronics.com.au/guides/force-sensitive-pads-raspberry-pi/. But there are some mistakes in their circuit which can damage your raspberry pi. My most recent video explains how to fix (need to use the 3.3V instead of 5V pin)

It varies a lot depending on where you live and what level you are. From what I’ve seen, this website has decently accurate numbers: www.levels.fyi/

NixOS is a complete mess and not nearly in the same realm as Ansible

I've been using NixOS for years, and I'm a big fan, but no, it doesn't make ansible; not even close.

@@Hedshodd Hi. Can you explain a little more?

​@@saeedjalali7339 Another user/fan of NixOS and Ansible here. They're two different projects with two different goals. NixOS's is making a truly declarative, repeatable operating system. Ansible's is declarative, automated configuration of infrastruture. NixOS isn't going to build my Cisco switch, nor is it going to manage my company's red hat systems. Ansible isn't going to ensure, beyond a shadow of a doubt, that my system is exactly what is described in its scripts; just that what is declared there has been done. Both are extremely useful tools and will continue to be

diff is for sure more useful generally

It's surprisingly not that intuitive, but once you understand the principle, you see it everywhere.

Not in this case. For example, if I push down on the cup without the holder, the number will switch to one.

That’s definitely an option. I appreciate the feedback. I’ll spend some time looking for a switch that could satisfy the requirements. The hardest part might be the size considering I don’t have the materials to construct one myself

lol that’s definitely an option. I’ll have to think of a way to add more mass without disrupting the cup position too much

Awesome! I’m looking forward to working on the next part!

Thanks man!

My expertise is in software development so I’m probably missing something here. Do you mind explaining a bit more on how that would work?

Pressure = Force/Area. If I'm not wrong, @jamesskymobilivion is suggesting reducing the area at the base of the cup to increase the pressure. I'm not exactly certain what your measure is (it looks like just the voltage of the circuit) but there could be a couple of fixes. One suggestion could be adding more resistance to increase the voltage of the sensor. I'd assume that because it's a binary input, if you raise the "resting" voltage closer to 3.3V, the system would theoretically take less force to trigger (I'd assume).

That’s great to hear! It’s been fun working on this and I’m excited to continue

That’s a great point. Since I am looking for binary input I concluded that there wasn’t any more need for the ADC. However you’re 100% correct. I would definitely get more detailed input and can calculate the binary result myself. I will definitely retry the experiment with an ADC

you need it

Thank you!
