The latest ongoing project: A block calibrator.
Since I needed something to generate cold and hot in order to calibrate my sensors (NTC), I decided to go ahead into this project. (I tried to keep the cost as low as possible)
- Peltier Module
- Aduino Mega
- ADC converter (ADS1115)
- Aluminium Profile 2020
- AMD or Intel CPU cooler (I used a water cooled system)
- PC Power Supply
- Aluminium for the dry-well
- Frame Designer (www.framexpert.com)
- Arduino IDE
- VB or similar for user interface
I started to make a sketch of frame on paper adding dimensions of parts and positioning (for complicated things usually I use Frame Designer). I ended up with something like 42 cm x 19 cm x 30 cm. Everything after cutting and assembling should fit into the frame.
The next step was to build the Power Supply and water cooler. I designed quickly the part using Inkscape and cut the thing in MDF using a laser cutter. Following, the design in pdf
To be continued…
Some leak checking after installing the pump…
The project is still on-hold, I got problem with the quality of the cooling tank. The acrylic completely cracked!! Need to find a replacement.
Done, the new one is on the way. I will start again to work on this next week.
