Sometimes, your ESP based project doesn't need a dedicated USB to TTL chip because you won't upload the firmware so often (especially on custom / embedded projects).In this case you can use a dedicated USB to TTL module, to help you upload the firmware.But as you know, sometimes ESP chips needs to have certain pins tied to GND in order to enter boot mode, so you have to either add a button to do that, place some solder pads and use a tweezer to short those pins or some other methods.To be honest...

DIY Advanced Plasma Rife Machine
Pavleski Mar 10,2023
 Royal Raymond Rife was a scientist, inventor and medical researcher (1888-1971). He is known for his microscopes, which he claimed could observe live microorganisms but also by an electronic device constructed by him called the Rife Machine, which according to his claims, is capable of curing very serious and incurable diseases. In order not to repeat myself, if you are interested in the method of operation, making, technical characteristics, the way it is claimed to heal and many oth...

3x3 Macro Keypad
M Mar 07,2023
Simple 3x3 Macro Keypad, I made some time ago using CherryMX switches, some SK6812 Mini-e RGB LEDs and a small 0.91" OLED display.You can replace switch 1 (S1) with an rotary encoder if you want.Since it uses an Arduino ProMicro - ATmega32u4 chip, you can program the this macro keypad with Arduino IDE or via QMK Toolbox.However, if you use QMK you won't have OLED functionality.I attached bellow, a small sketch for Arduino IDE with a code example (please be sure you have all the libraries require...

SEGA Synth
Nikolaj Mar 07,2023
Introduction and rationaleMost synthesizer musicians will have heard of the legendary Yamaha DX7 synthesizer. Released in 1983, its powerful and characteristic sounds defined the decade and the one that followed, with up to 40% of the yearly hit songs in the mid 1980s in the US using just one sound of the DX7! Due to the resurgence of retro-themed music and aesthetics, the demand for DX7 synthesizers is increasing, however given that they haven't been produced in around 30 years, their supply is...

LORADUINO USB to LORA converter
penev_milen Mar 06,2023
The Arduino is widely used platform for lot of applications. Despite its all advantages in some cases it is not very convenient to use - for changing some parameters in the program it always requires direct cable connection with your PC. For example: If you have an Arduino controlling or monitoring system placed distantly from your house and you want to update the software, to upload the new sketch you have to go there where the Arduino board is suited, connect it throw USB cable to your PC and ...

A "Nixie Tube" Style Desk Clock
Freeform Builds Mar 06,2023
I wanted to replicate the design of those cool looking "Nixie Tube" clocks but with a freeform circuit style that I enjoy making, so I decided to make this. Overall I think this idea can be taken further and a lot of others things could be built with this style of 7 segment led display (I have a lot of ideas in my mind, just need some time to make them).This design does require a fair bit of soldering work and does take some time and patiences to complete, but the end result is definitely worth ...

ESP32 Internet Radio, MP3 Player , and Alarm Clock
Pavleski Mar 03,2023
  Internet radio (also web radio, net radio, streaming radio, e-radio, IP radio, online radio) is a digital audio service transmitted via the Internet. It can either be used as a stand-alone device running through the Internet, or as a software running through a PC.  This time I will show you how to make a stand-alone Internet Radio, which in terms of characteristics, stability, and functions is comparable and even better than commercial devices of this type, and yet the pric...
