ESP32 for you: bit.ly/2OcyP77
Seems like they finished Bluetooth Classic now!
First impressions and first working project with Espressifs new dual core SoC. Controlling 450 WS2812 LEDs and adding a bare minimum of security to a Bluetooth Low Energy connection.

Cat would attack the LED stripe, possibly destoying it with one of the knives embedded in the fluffy paw.

Hi Marco, thanks for your insight and sharing your experience. I knew these were going to be powerful but I lost track with the ESP32 development just as they came out and I was focussed else where. I will definitely be getting some of these soon!

3M's Z-axis tape may work in place of pogo pins. It is a conductive tape, but only conducts in the z axis (top to bottom). I'm not sure how well it would work with such fine pitch, but in theory, you could just put some over an esp breakout board, then press the esp on top to program it.

Hi Bro!, I'm on a school project with this chip right now, and I'm having difficulties with the concept of allowing only specific conexions, I'm using arduino core, and I think your aproach of the button could help me so much, do you think that you could share or teach me your concept of the button ? only the side of the esp, I think the android event I can handle it, maybe I did't get quite well what is doing the code in the minute 3:47. Thanks for your video bro, is really helpful to see some of the interesting things that can be done with this esp.

Man, you need to make a reddit, or something like that.

Could you tell the settings you are using to solder this chip and maybe some tips. I tried 2 times to solder esp32 using hot air but without success... I was able to solder it using soldering iron but the result is not as pretty as it can be. Thanks for the video!
@iwantitpaintedblack

preheat the board surroundings, use lots of flux, perhaps pre tin the pads, or for more ease use a solder lead paste,

@leozendo3500
@leozendo3500 7 років тому
Why this project top secret? Is it possible to transfer ESP8266 file into ESP32 directly in Arduino IDE and have everything compiled and work? I am trying to control 250 WS2812s in a matrix with a ESP32 to display animation, text and work as spectrum analyzer but it was hard.

can you please upload your RMT code for the LEDs? I implemented some esp-idf library but when I use WiFi at the same time the RGB pixels get corrupted and false colors....
@arminemmert8250

Makes me think of ADC2 pins on the ESP32, that can’t be used when wifi is on.

Can you share the code for the bluetooth communication? I spent 2 days on the espressif examples and felt I didn't make any progress.
@reps
@reps 6 років тому
What part do you need? I have recently tried to compile my old code with an updated esp-idf and got dozens of errors because of changes they made .... But I think most of it is in the examples!

@gvukster
@gvukster 6 років тому
is this computer science, electrical engineering; I'm interested in this stuff and wondering what type of education I would need to learn the basics of the things on this amazing channel?
@akj7
@akj7 6 років тому
Actually, there isn't any special education you need. I study math and i program Microcontrollers as hobby. Ok i have to mention that everything started as i was asked (without any previous experience) to build some kind of arduino based robots. Microcontrollers are (mostly) easy to learn, C and python (and maybe Assembly) are too. However, students in informatics, electrical and mechanical engineering (mechatronics) will one way or the other, learn about microcontrollers.
@gvukster
@gvukster 6 років тому
Jules A, I'm a Mechanical Systems Engineer and we only touched briefly on Microcontrollers in my studies... I imagine to have high proficiency in this technology either electrical or comp. sci. would be most beneficial, that's why i queried the community. looking to take some post grad and college night classes to stay up to date.. Thanks and cheers from Steel City Canada
@akj7
@akj7 6 років тому
gvukster At my university, there is a course on microprocessor for mechanical engineering. However, this only explain the structures. I believe the best way to really learn about microprocessors, is to use them and hobby them, brief self-teaching, assuming one already has knowledge about basic electrical engineering.

Sure, I have multiple Arduino shields, I program in Python, C+, MatLAB, I built a 4-axis CNC, and I have a 4 year Mechanical Engineering Degree specializing on Solids,,, I know that certain topics need formal training on especially for commercial application; my daughter is interested in this stuff more than Mechanics so I was curious as to the communities response.

I'm not one for outward show of emotion or even admiration. I'm logic oriented no matter how eccentric my logic gets. It's still logic. But having watched many (all) of your videos and I'm embarrassed to say, your monotone robotic voice, sense of humor so dry the Sahara would be jealous and dare I say, incredible physical attributes such as a noble and handsome face, and bionic posterior, and general emotion free presentation of your work have caused me to turn my homes air conditioning on max as you have made it too hot to handle. I imagine you are a cyborg of my design with artificial intelligence far superior to any being developed by so called genius scientists. Please, my left lobe candy brain wrestle them to the ground with my right lobe restrained. Genius my also bionic posterior. Any way, I imagine I created you to replace a biological son who did not inherit my brilliance and therefore can never earn my respect. Therefore I created you, Marco Reps to be the son I can respect and admire. What a delight then that your northern German accent and monotone voice resemble that of a cyborg. I'm tempted to invite you to my home in the United States to act out this dream. Don't worry, I don't have any biological offspring, therefore there won't be any concern of sub par feelings being trampled upon. Any way, I would be proud to not be a father figure or inventor, but to be a friend and who knows, I've already gushed like a school maiden, if your tastes run to the highly evolved and open sourced, part time student...or lover. Which ever gets your rocks off and curls your toes. I'm down for the getting down. But that's enough of that. If I embarrassed you, you have only your self to blame for shamelessly flaunting your robotic hotness all over my now sticky UKposts screen. How is anyone with superior IQ supposed to resist. You digital pile of binary sexiness!
