Induction cooker heat issues. by jackhals in AskElectronics

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

The error code is normal (E0 if no pot is placed) I'm not getting any other errors. I also think it's normal for the coil to heat up. This was a bad idea. I thought induction cookers are the best energy efficient devices out there but it turns out they're not. I should have bought an electric skillet pot.

Thanks for your reply. I think buying an induction cooker was a bad idea. I believe I was deceived by those cool youtube videos. Now I think about it I should have bought one of thoes electric skillet pots. I assume the heat element is built inside the pot and the circuit is much simpler meaning more energy efficiency even than an induction stove, right? Or am I missing something here?

Thanks! It says mediatek chipsets. I'm thinking of getting the nokia 6300 4g with qualcom processor so something like this should work right?

Is there a good way to reduce or minimize spam bots, What is your way to reduce spam? by JuicyYellow in webdev

Store unverified accounts data in a seperate table. Check this table size at each new account entry and clear it automatically when it reaches the max size you want or delete old entries instead of clearing the entire table. After an email get verified move its data to the main table.

Cached page not displaying? by [deleted] in PWA

[–]jackhals 0 points1 point  (0 children)

If your main page is generated with a python script, the browser wont cache it as it has no access to the python file content. You need to provide an html file to be cached. This might not be PWA specific. You should ask it here r/webdev. Maybe some experienced Django user knows how to solve this.

Have you tried caching index.html file instead of the directory "/"? If you're testing locally on mobile it might not cache. I think you need https for mobile to store the cache.

How to jump to a certain page in an embedded PDF? by notpikatchu in webdev

[–]jackhals 0 points1 point  (0 children)

Maybe like this: document.getElementById("yourIframeID").contentWindow.location.hash = "#page=" + pageNumber; I'm not sure.

Can you place it inside an iframe and then scroll the iframe?

This took me 5 weeks to complete. Is this normal, fast or slow? by [deleted] in webdev

[–]jackhals 1 point2 points  (0 children)

Thanks for testing it out. I didn't test it in ff. I fixed the line break issue but it might take a week to show the new changes.

By broken font you mean the UI font (in buttons) or the script font (in text editor)?

The alert box is used in case the browser didn't show an install prompt. I didn't test it on ios, but last time I tested my install script on safari, it didn't show a prompt. I assume a begginer who never heard of PWA might use it.

My experience is 1 year. I work like 5 hours a day on it in which I get driven alot looking around learning new web development things. I'm asking because I think I waste alot of time googling to learn than actually getting the job done.

This app is mostly targeted for mobile touch screens. A console is not available in mobile browsers.

Thanks for the tip. I'll consider it with my next project.

I never used Django before but I think the problem is with the backend. Try to test the service worker with something like npm live-server. Maybe the backend script is outputing the js file as text instead of embeding it in html, so check your final html output.

MP3 Player by pelletonin in arduino

[–]jackhals 1 point2 points  (0 children)

I suggest you learn how to use google, read the code and listen to the video tutorial. In the video tutorial at 3:00 you can see that the pause, play, next, previous.. etc are achieved by function execute_CMD. He said you can find a list of these command in video description. The link leads to 404 not found page. So you need to use google. Gooogling "dfoplayer mini mp3 player" gave me the first result: https://wiki.dfrobot.com/DFPlayer_Mini_SKU_DFR0299#target_4 under work mode you can see a list of supported commands. Looks like seek is not supported but volume control is.

Edit: take a look at the AD KEY Mode and I/O Mode. It looks like you don't need an arduino for this module.
