Two ways of building the incubator
Incubator bill of materials:
Bill of Materials
Needless to say, you will need an Arduino UNO or equivalent microcontroller.
Components that are needed without using a Biohack Board
These are the parts you will need to assemble the incubator:
| No | Amount | Description | Supplier NL | Cost |
|---|---|---|---|---|
| 1 | 4 | 3mm MDF 95 x 45 cm | Local wood store, like Houthandel Schmidt | 5.00 |
| 2 | 1 | Expanded polystyrene (EPS) | Praxis | 7.99 |
| 3 | 1 | 3mm Acrylic sheet 27 x 41 cm | Plexiglas.nl | 3.50 |
| 4 | 1 | 12V 80 mm Axial Fan | EOO, Farnell | 8.99 |
| 5 | 1 | Power switch | iPrototype | 0.95 |
| 6 | 1 | Water proof temperature sensor (*1) | HobbyElectronica, iPrototype | 2.95 |
| 7 | 1 | I2C LCD display | iPrototype, (HobbyElectronica + HobbyElectronica) | 16.95 |
| 8 | 2 | MOSFET | Farnell, EOO | 0.98 |
| 9 | 4 | 10K resistor | Farnell, EOO | 0.06 |
| 10 | 1 | Diode | iPrototype, EOO | 0.19 |
| 11 | 2 | Button | iPrototype | 0.55 |
| 12 | 1 | White LED | iPrototype, EOO | 0.52 |
| 13 | 1 | 220 Ohm resistor | iPrototype, EOO | 0.45 |
| 14 | 1 | 7.5 W power supply | iPrototype, EOO | 13.95 |
| 15 | 1 | Jack Adapter | EOO | 0.85 |
| 16 | 1 | Heating foil | Conrad | 20.68 |
(*1) In case you choose for the DS18B20 temperature sensor, you will also need a 4.7K ohm resistor
Components that are needed on top of the Biohack Board
| No | Amount | Description | Supplier NL | Cost |
|---|---|---|---|---|
| 1 | 4 | 3mm MDF 95 x 45 cm | Local wood store, like Houthandel Schmidt | 5.00 |

Alternatives
- When it comes to the building materials, such as wood, plastic and EPS it’s cheaper to buy in bulk with some fellow students and chop it into pieces. The cost in this overview is already corrected for that somewhat. Also resistors and LEDs are cheaper in bulk.
- Instead of Arduino UNO you could permanently build in an Arduino Mini Antratrek EUR 9.56 or something even simpler. We’ll go into that later during this Academy, so don’t glue your Arduino to the incubator!
Nice to have
A lever switch for detecting whether the lid is closed and a speaker as an alarm would be nice.
| No | Description | Supplier NL | Cost |
|---|---|---|---|
| 1 | Lever switch | iPrototype | 1.99 |
| 2 | Speaker | iPrototype | 1.55 |
…
These zebrafish have lines.
So I used a slower shutterspeed to just capture the lines.
