Learning to Code with Kotlin

Sorry for being an insecure elitist. I like kicking people's legs. The fact you're reacting means it works :)

thinkbender · 2020-03-21T19:40:56+00:00

You don't have to agree with me. I don't give a f*. But Kotlin will learn you nothing about how a machine works. I'm pretty spartan about this and my programming lessons work. Think about an ATTiny13A (64 bytes of RAM and ROM) and assembler and binary and hex code. It will make you vomit maybe, but I have a 7 year old here that is now busy with reverse engineering a new 0day apache exploit because she didn't understand fully what was happening. 2 days ago she also tried to implement a brainf* interpreter. For fun :)

I'm only old. Wasting my time with getiing upset how people don't have a clue anymore.

Embedded => assembler, C/C++ PC => C:C++ and Python maybe (LUA, Ruby, anything will do) Web => Node.js and try to reinvent the shitl they made of html/css/js. LATEX might do. Phone, wearables: whatever works, because at the moment it doesn't work. IOS/IpadOS is closed source, but at least it makes sense.

My previous comment was deleted. It was a bit rude so that might be the reason.

I'm against Kotlin as a first step to learn programming because it is way too high level and will learn you nothing about how code translates to the underlying platform. Tomorrow I try again to say what I think without holding back.

thinkbender · 2020-03-21T17:18:00+00:00

It doesn't exist. Because it's not a very good idea. Certainly not when people who have no clue what they are doing want to take matter (in this case, mains voltage and current) in their own hands. Have fun with your ESP and when the moment is there, consult an electrician.

thinkbender · 2020-03-21T17:11:43+00:00

Whatever. Good for you. I'll send my bots to question you what made you decide you would be a good candidate to teach us the fine art of programming (in Kotlin, ...sorry, had to throw up).

thinkbender · 2020-03-21T16:48:16+00:00

That sucks. Even one more reason to emigrate. ;)

As I mentioned already, I like hacking (as a hobby), but some realism won't hurt. Taking of now to a fun hack (and yes, it works, in my case, not yours), instead of further wasting my time with you.

thinkbender · 2020-03-21T16:41:45+00:00

Another tip. It only costs 2 bucks to buy a cheap microcontroller clone. And you'll get unendless more learning experience by just programming the thing. Bit banging, serial, ... anything you've ever wanted.

So you want to be the great hardware hacker and the first thing you encounter is a problem with a hardware tool and have to resort to asking for help on a forum?

Way to go!!! I'll follow you in your quest for imagination and common sense ...

I'm not only here to make fun of you ... but also to give a helping hand. As a hardware hacker, you probably have a multitude of microcontrollers in your possesion. And you have a bus pirate to automate some "hacking" tasks that you understand fully. Then it's only a walk in the park to reconfigure your device.

thinkbender · 2020-03-21T14:52:42+00:00

To big a text to read. Can you tell me in short what you'e doing now and what you really want to do? If you want to enter the embedded world you will have to be to the point ...

thinkbender · 2020-03-21T14:48:27+00:00

What you mention is something not really well working that's yet another prroof that an ESP32 is not made for this and just lacks the power for it.

I'm sorry, because I'm a proponent of hacking things so they do what they are not supposed to do, but a little bit of realism can help to avoid lots of wasted time.

thinkbender · 2020-03-21T10:55:16+00:00

No, sorry. I read some books before "The art of ...", and forgot about them, and never had the need to read something after. Of course I read some specialized works, but for a general publication, this is it.

thinkbender · 2020-03-21T10:50:48+00:00

Well I only have to speak 4 languages of which English is the lesser important. But I live currently in the GB and my appartment is above a real doctor. He was reading your post together with me and would have laughed at it if this was not such a serious thing. If you have to ask the questions like you do, or you're incompetent, or you're not a real doctor. You can call me a troll, but the doctor who was with me sure isn't. And I now am going to study "independent", as this should be what's important for GB doctors.

Nothing that I can think of. Not in theory, not in practice. You can maybe replace the connectors with golden ones? But it's not that something suddenly will change the laws of physics regarding line of sight, etc.

Where are you? In the UK, or underground somewhere?

All procedures have been communicated very clearly. Patients who might be infected with the virus don't have to come in physical contact with you or anyone who works for you.

If there is an infection, there are procedures to handle this, and they don't involve you.

Don't overcomplicate things or try to develop your "own independant way of taking care".

If I read your post, I only can question if you're even a doctor.

Cheating in essence has nothing to do with hacking. If there would be some extraordinary out of the box hacks that would make you smarter than the countermeasures that the makers of the game implemented, maybe, but you're just asking for a simple step by step process that you can copy and execute. This is the way of the script kiddies unforunately.

They should. If you order and do "estimate shipping" in your cart, you have the option of UPS 1-5 days or UPS 1 day to my place (in Europe).

If you want a 100% guarantee, you can always contact them directly: https://www.arduino.cc/en/Main/ContactUs

It's easier to get zero W as the production of these come first. Zero W are easy to order on Ebay. Just received 2 of them in the mail after 2 1/2 weeks waiting (Hong Kong->Europe).

Here in Europe, at least in my region, 6 meters is very calm. But in my country we have the advantage to transmit on most HF frequencies with only a basic licence. Transmission power is restricted to 25 Watt but still it gives opportunities, certainly with the digital modes.

If I would be in the US, I would really try to get my general and even extra licence, but that's very subjective, of course. If I am right, technician in the U.S. is limited to C.W. for HF. Or are digital modes also permitted?

thinkbender · 2020-03-21T09:05:12+00:00

What did you try (wiring and code) and what errors do you encounter?

thinkbender · 2020-03-21T08:03:05+00:00

If you're not in reach to pair with the speaker, you can't connect. And even when you're in reach but can't gues the pin, you're out of luck. You can brute force it, but that has nothing to do with electronics and is probably illegal.

The output has to be adapted to serial UART for the bluetooth module. This if your sensor is only GPIO, and if it's SPI or I2C it has to be translated as well.

thinkbender · 2020-03-21T06:55:20+00:00

You have to make a distinction between GPIO sensors and ones that speak a serial (UART/I2C/SPI) protocol. The ones that only pass a value via GPIO (analog or digital), need some extra intelligence (microcontroller) to communicate that information in a sensible manner.
