RandomData Drone (RaDD)
RandomData is going to build a drone, for ethical use off course. Just to discover the possibilities of a Unmanned Aircraft System (UAS) and to get some knowledge on this subject.
Brainstorm
We held a brainstorm session for our own space drone. The RandomData Drone (Radd). We first made a list about the possibilities what we could do with the RaDD.
- Automatic burgular system, hovers around your home when home alarm is activated, and take's pictures of suspicious cars and people.
- Wifi deploy, a mobile Wifi AP.
- Warflying, some Wifi harvesting.
- Cloudpoint images, make a 3D image of the city.
- Operation doorbell, 433 MHz hacking drone.
- T.V.DroneGone, a universal flying t.v. switch off.
Platform
The decision is made to make a multicopter platform. By building the platform with the modularity in mind, it will be possible to easily change payloads. Therefor it can be used in different projects. Ardillo makes a list with the possible parts. This list is just a guideline to get a grip on the expense.
Parts list
The parts are selected from www.hobbyking.com, with the price in mind. As warehouse it is possible to select the Dutch warehouse, but they are a bit more expensive. So therefor we used the global warehouse for making the list below. These are only the basic parts for making the quadcopter fly by human interaction.
| amount | what | url | price | total |
|---|---|---|---|---|
| 1 | Q450 frame - integr. PCB | Q450_Glass_Fiber_Quad | $7.99 | $7.99 |
| 4 | AX Brushless motors | AX_2810Q_750KV_Brushless_Quadcopter_Motor | $18.56 | $74.24 |

| 1 | charger | Turnigy_Accucel_6_50W_6A_Balancer_Charger | $22.99 | $22.99 |
| - | - | Total | $356.78 |
This is around €272.73 when ordered from the Dutch warehouse the total price is: €293.88. Some parts need to come from another warehouse because the Dutch warehouse doesn't have them.
Idea
When wandering on the big bad internet Ardillo found this thing, almost to cheap to make it yourself.
It uses a multiWii board as flightcontroller, the same you can buy at HobbyKing for around $20. It makes you think why are these complete drones that cheap... you can break a couple for that price.
For more information about the multiWii flightcontroller take a look here.
more to come...
