How To build, install and wifi setup?

To build an iBLOPPER you need

  • 1x Wemos D1 Mini or NodeMCU.
  • 1x DS18b20 probe, 1 meter, + resistor (4.7K Ω Resistor) or shield version of DS18b20 as “DFRobot Gravity – DS18B20 temperature sensor”.
  • 1x MPU6050 or a “Grove – IMU 9DOF v2.0″.
  • 1x Waterproof-Plastic-Electric-Project-Case-Junction-Box-55x35x15mm or or just a TickTax box. Including some moisture protection (Balloon, tape).

iBLOPPER “NodeMCU” solderfree.

A solder free version can be build around 20-22 $/EUR if making use of Grove – IMU 9DOF v2.0 as gyroscope. If also using a shield for D18B20 temperature probe, you can build a iBLOPPER without any soldering at all based on below diagram, etc. You will also need one “GROVE – 4 PIN FEMALE JUMPER TO GROVE 4 PIN CONVERSION CABLE”. This version will be a bit more expensive, around 20-22 EUR/$ vs. the 10-12 for the soldering BOX version, see below.

Diagram for iBLOPPER for NodeMCU. Please notice you can make use of 3-pin temperature shields as “DFRobot Gravity – DS18B20 temperature sensor”, or “Iduino SE029” as D0 is turned low (equals ground) and D1 turned high (equals 3v3).
Grove – IMU 9DOF v2.0
DS18b20 temperature probe + shield. For other temperature shields please see “DFRobot Gravity – DS18B20 temperature sensor”, or “Iduino SE029”
iBLOPPER “None-solder” version based on Grove – IMU 9DOF v2.0. Here with “DFRobot Gravity – DS18B20 temperature sensor” as this one is so easy attached at D0, D1 and D2.
iBLOPPER also works fine with other types of airlocks, even not tested in full. Again, here with Grove – IMU 9DOF v2.0. Here with “DFRobot Gravity – DS18B20 temperature sensor”.
iBLOPPER “None-solder” version based on Grove – IMU 9DOF v2.0. Here the NodeMCU “lolin” is packed away in a Tick-Tack Box. The IMU sensor should be protected by a small baloon to ensure blow-out do not harm it. This version with 1 meter long temperature probe.

Please notice, as an alternative till Grove IMU 9DOF v2.0 sensor, you migth also make use of Adafruit MPU-6050 6-DoF Accel and Gyro Sensor + connector 15 cm. Downunder Australia “PiicoDev Motion Sensor MPU-6050” is sold + connector 20cm. I have not tested any of these, but they should work I guess.

Wemos D1 Mini (Soldered Box Version)

Diagram

Below you find the diagram of D1 Mini build.

Calibration for all versions

At iBLOPPER CLOUD you can set the sensitivity or treadshold when a bubble should be detected. All versions of iBLOPPER should have 3 till 6, and I find 4 to be best. But you can finetune if needed to remove double blops or if you loose any.

NOTICE: The iBLOPPER do internally calibrate the MPU6050 during the first 5 sec after turned on and it is important it is placed on the airlock and hold still at the moment it do this internal calibration of the MPU6050.

Installing and install files

To install you need:

  1. Install CP210x USB to UART Bridge VCP Drivers so you PC can find and see the NodeMCU/Wemos D1 Mini.
  2. Install ESP Home Flasher, e.g. flash program to flash install-bins (see below). The flash program also give your the possibility to see and view what going on inside logger (see video above).
  3. Download the below Install-bin files accordingly.

Ton install the bin file you should use “ESP Home Flasher”, and please also notice this flasher program can be uses to see what happens in the logger during the run. Hence, please use it to play a bit around and check everything.

Install files:

(Please notice version 2.3.2 and onwards contains a out-liner system and hence compare the BPM with former run, and removes BPM over a given treadshold as outliners. Therefore, ver2.3.2 will not show the correct number if you just tap wildly on the logger. Hence, if you wish to see correct blops (or taps) it is best to try start out with version 2.2.2)

BETA-2: iBLOPPER ver2.3.2 (Files for NodeMCU and D1 Mini). (33 downloads) iBLOPPER ver.2.2.2 "STABLE" (Files for both NodeMCU and D1 mini). (31 downloads)

Obsolete builds:

Setup WiFi

The only thing you need todo in iBLOPPER is to enter the WiFi credentials of your WiFi network:

Please notice the 7_8 chipher iBLOPPER number as you must use the number as your username when register your account at iBLOPPER CLOUD.

Register and login

The final register and login should be simple, else please see video. Please notice you must use the iBLOPPER number as shown above under Setup WiFI.

Version Log!

iBLOPPER ver2.3.2 (BETA):

  • BETA – Out-liner system: A system to remove outliner BPM if above x times the last cycle for BPM under y in avenge. This should remove for instance high BPM from moving fermenter around or taken a sample. Likely, not bulletproof.
  • Correcting the “Major error setting Sum Blops/L to null”.
  • Correcting errors in ver2.3 + 2.3.1.
  • Streamlining code.

iBLOPPER ver2.3 + ver2.3.1 : Pulled. Major error setting Sum Blops/L to null.

iBLOPPER ver2.2.2 (stable):

  • BPM max. from 180 till 300.
  • Updating the error system if IMU/MPU not found.
  • Version system of the iBLOPPER in use implemented. Hence, giving information in iBLOPPER CLOUD when to update.
  • Re-building the fallback system for settings of sensitivity/blops time if CLOUD is down.
  • Update WifiManager, and including to Update software though Wifimanger.
  • Settting D0 as ground, D1 as 3v3 on NodeMCU, hence, to allow for other ways to connect temperature probes by 3 pin connectors (as signal at D2 it fit 3 pins connector of “DFRobot Gravity – DS18B20 temperature sensor”, or “Iduino SE029”).
  • Temperature probe no longer turns 85´C at first measument.
  • Correcting generals errors in ver2.2 + ver2.2.1.
  • D1 Mini temperature probe turned “200000´C” on some builds.

iBLOPPER ver2.2 + iBLOPPER ver2.2.1: Pulled. Major error setting Sum Blops/L to null.

iBLOPPER ver2.1: Fist release with iBLOPPER CLOUD.

iBLOPPER ver1.3: Latest release by PORTAL mode.
