D1 Mini Version

iBLOPPER can also be build for D1 Mini. This version is more lean and smaller, but needs more soldering as intended for more advance users. In this version the blue LED lights up all the time but stops emits blue when a bubble is detected (also it stop light blue in portal mode). The first 2 sec of power it light blue as it calibrate itself, hence, hold it very still.

The MPU6050 goes upper site on till the D1 Mini by the 5Vof D1 Mini til VCC of MPU6050, GRD till GRD, D3 till SDA and D4 till SCL. The temperature probe goes till 3v3 for power (red) of probe, the black (ground) goes til D8, and the signal goes till D7. Between 3v3 and D7 the resistor is placed.

Needed components

Makershop DE should hold the most.

Install file and install

iBLOPPER_ver1.1_D1MINI (2 downloads)
  1. Install CP210x USB to UART Bridge VCP Drivers, if not already done. If you played with Arduino IDE and NodeMCU before you most likely have done this before.
  2. Ensure NodeMCU is pugged into USB.
  3. Go to “Devices” (e.g. use win10 search and write “devices”).
  4. Under “Ports” in Devices. Notice this USB port number for “CP210x USB to UART”!
  5. Edit the “Window batch file” named “SETUP_USB_COMX” to reflect the port you using (eg. change the port number ONLY: “esptool.exe --chip esp8266 --port COM4 --baud 115200 --before default_reset --after hard_reset write_flash -z --flash_mode dio --flash_freq 80m --flash_size detect 0x0 iBLOPPER_v1.1.bin“)
  6. Hit and run the “Window batch file” named “SETUP_USB_COMX”
  7. Now the iBLOPPPER software get installed.

If something goes wrong you can erase everything after editing accordingly as above by running “Erase_USB_COMX” (esptool.exe -p COM4 -b 115200 erase_flash). 

If updating to new build and/or making use of an NodeMCU from earlier project, ensure to erase everything as else you will get instability issues.

Secondly, always pull the pwoer from iBLOPPER after installing before setting it up.
