Hallo Stefan!

Du hast hier einen wirklich tollen Blog mit vielen interessanten, gut dokumentierten Projekten erstellt, vielen Dank dafür!
Bei der Internetrecherche zum "Retro Projekt – Voltage Blaster" habe ich die Weiterentwicklung, den "Enhanced Voltage Blaster" entdeckt (https://github.com/chadr/Enhanced-Voltage-Blaster). Sieht interessant aus, wobei die zusätzlichen drei LEDs (und Vorwiderstände) eher Spielerei sind und bei der Bestückung weggelassen werden können. Wenn man nun noch das Platinendesign komplett auf SMD umstellt (und auch auf den Jumper verzichtet?!), hat man ein Projekt, dass sich kostengünstig herstellen ließe, ohne noch selbst zum Lötkolben greifen zu müssen (quasi den "Enhanced Voltage Blaster Lite")…

Liebe Grüße aus Niedersachsen,

Thomas

Hello Stefan, thank you first of all for this nice little board with the good instructions. Unfortunately, I got carried away and desoldered the MQ-2 sensors and repositioned them. I haven't managed to get the sensors working again. This is because the wires are not making contact with the fine traces at the former pin holes of the MQ-2.

Is it possible for you to tell me the contact points of the sensor so that I can solder the wires directly to the components?

Best regards from Rüdiger

Hello Rüdiger,

Sorry for the late reply. If you post this to the contribution, I usually see it faster as not many people visit my guestbook otherwise 😉. I must clarify one thing, the board is not mine, I only got it and tested it, so the thanks belong to someone else. hopefully it worked ;).

In file lib/App/DeviceConfig.hpp
Current: #define MQ2_PIN A0
defined, so A0 should be your pin.

Dear Mr Stefan,

You write in the "Preview – INA3221 Power Monitor" about the data that this module can measure up to 3.2A current. If I interpret the data sheet correctly, the shunt resistor would have to be adjusted for this. With the standard resistor of 0.1 Ohm, it is only a maximum of 1.638 A per channel. Or am I making a mistake here?.

Kind regards and Happy New Year!
Mario

Stefan, your contribution with the ESP to Alexa is really great. Thank you so much for explaining it so well. I'm impressed.

I read your ESP32 pages with interest. I wish I could program with esp-idf and C, but after installing the idf I failed with the problem that after working in the Esp32 IDF IDE the
Unfortunately, the „Build“ there doesn't work. The book by Brandes also hasn't helped me much. I would be grateful if you could recommend any literature or web articles to help me with this. Kind regards, Franz Hofmeister

Hello Franz (I hope you are well?)
On Windows, installing the IDF is always a bit tricky due to Python versions. You always have to try a bit. I found it easiest to do on Linux, where MOST things fit together. I'm not a real Linux user, but I managed. However, it's not comfortable without a GUI.
Otherwise, unfortunately, I cannot recommend any literature; I always do this directly via the Espressif website. I've also written a few guides for Espressif, but they are rather short and to the point, and I improve them every time I install something myself (there should be a few links there too). Otherwise, I could only offer to send me an email with the exact error, and I'll have a look, but I'm also just a user; if something out of the ordinary doesn't work, I usually have to give up and try things out.

Hello Stefan, I've had a HuskyLens module for a few days and I'm testing the first project "Object Tracking Pan Tilt" with it:
https://github.com/makertut/huskkylens-pan-tilt-object
https://www.youtube.com/watch?v=k-LXs94nRaU

Unfortunately, I only get error messages when I compile the sketch on the Arduino UNO:
class DFRobot_HuskyLens' has no member named 'writeOSD'
I suspect the library is no longer up to date.
Can you perhaps give me a tip based on your experience? I'm not a programmer and I'm looking for a working sketch for the UNO.
Best wishes, Ulli

The instructions for the Arduino VS1053 MP3 audio shield do not work.
The SFEMP3Shield.h library is causing an error. I don't know if that's the only reason, but at any rate, nothing can be heard.

It's a shame it didn't work out for you. The error description is unfortunately a bit sparse to delve deeper into the analysis 😉

Hello Stefan,
I'm currently gaining my first experiences with the ESP-32. I found your blog via Google. You've compiled the most important information in German very clearly to overcome all the hurdles for getting started. Thank you very much.

I saw many other interesting features on your site while I was there, I'll be back.
Greetings Jörg

Hello Stefan, you've helped me out of a hole with a few of my small projects now, and for that, I thank you. I enjoy reading your blog and taking inspiration from it.
Keep up the good work!

Hello Johannes,
I came across your interesting page while looking for information on controlling a DC micro-motor with an encoder disc. I need some help with controlling an encoder motor (25GA310-100, JGY-370, or JGA25-371). Any help in the form of a link or where I can best get informed would be greatly appreciated. Thank you very much in advance, and I remain with a big Arduino hobbyist heart – Johannes (replied 16.01.22 SFA)

Hello Stefan,
You have an interesting blog here. I was looking for information on the ESP32-CAM and that's how I found you. With your help, it was child's play. Keep up the good work!
