Spectrometer version 0.019

Version 0.019 is outdated.

xSpectrolum version v0.019

This is the second functional spectrometer in the xSpectrolum series. It was finished on 25 May 2020. It is built on an Arduino Nano board and 9 other modules (breakout boards or components) as shown in the wiring diagram below. All included modules/components are listed below.

xSpectrolum spectrometer version v0.019, the Bluetooth module should be BT10 (not HC05) but when writing this there is no fritzing component for BT10 available.

Spectrometer box

Compared to the previous version (0.017), version 0.019 has tilted light sources that focus 5 cm from the spectrometer. This is for allowing a more exact calibration using the solid sampler (see below).

Spectrometer solid sampler

The solid sampler fits on the front of the spectrometer box and assures that sampling is confined to the oval opening. All three integrated light sources, the strong led built into the Adafruit 6-channel spectrometer, the SMD 5050 RGB LED, and the red laser all point towards the oval opening.

Spectrometer cuvette holder

Also the cuvette holder fits on the front of the spectrometer box. The steering of the light sources through liquid samples is not finalized.

Assembly

xSpectrolum spectrometer version v0.019.

The neodymium magnet is too small to hold the solid sampler and cuvette holder in place. Assembling with crampon connectors is very tedious and also takes too much space inside the spectrometer box.

Modules and components

Apart from the Arduino Nano microcontroller, there are a total of nine different modules/components included in xSpectrolum’s spectrometer version v0.019. To get more information, including the separate scripts for individual controls, follow the links.
