- I'll make the electronic components needed, the vehicle mounts, the casings and program the modules.
- What materials and components will be used?
- The project will be comprised of a number of materials and components, such as PLA plastic, PCBs, MDF, acrylic and various electronic components.
- BOM(Bill of materials) for my setup, which is 1x control board, 2x button boards, 2x power boards, 2x jack boards

| 4.99k res | 6 | For circuits |
| 1uf cap | 5 | To regulate current fluctuation on boards |
| BUTTON_B3SN | 6 | 3x buttons per button board |

| SJ1-2533-SMT | 2 | Jack connectors, for data wire |
| Double wires | 1 m | For creating data wire between parent and child unit |
| USB cables | 2 | For powering devices |
| Jumper wires | 20 cm | For connecting boards |
| Plywood | Scraps | For the back boards |
| Plexiglass | 1 sheet or scraps | For the cover of units |
| Nuts and bolts | 8x | Attaching back plate to middle and front cover |
| Small screws | 7x | To attach boards to backplate |
| PCB | 1-2 plates | For milling of boards |
| 3D Print filament | | I used what I had laying around |
- Where will they come from?
- Most, if not all of the parts, will be sourced in the FabLab.
- How much will they cost?
- At this stage, materials cost will be very low, basically just a few dollars in materials/components.
- As I predicted, the cost is very low. For us here in the lab in Iceland, the cutting of a fresh Plexiglass plate is probably the most expensive thing. The ATtiny 1614 are below $1 at Digikey, and most other items very cheap in bulk and all are part of our FabLab inventory. I will set price at the sub $50 range!
- In terms of machine time, this project requires only a short a mount of time in the laser cutter, a bit of (large) milling time (~1h with setup), some small mill (PCB) time (~5 hours, if all goes well?), 3D printer time (~20 hours guesstimate) and some quality time at the soldering station!
- What parts and systems will be made?
- Electronic circuitry will be made, both enclosures and mounts.
- What processes will be used?
