Denne modellbåten av en amerikansk Arleigh Burk class destroyer ern en skalmodell i målestokk 1:87 (HO) Den er 1.87 meter lang og drives av to sykronmotorer på propellene. Hovedkontrollen er en Arduino DUE mikrokontroller, lastet opp med et Free-RTOS-basert multitask-system. Sensorene og styringsenhentene er koblet til et CAN-nettverk for kommunikasjon med hovedkontrolleren. Kommunikasjon ser med RF, RC, WiFi, Bluetooth og LoRa protokoller til base og dronerepeatere som fungerer som en simulert geostasjonær sattelitt for kommunikasjon med båten. Den har en områdesscanner som scanner nærområdet opp til 40 meter. Sensorene måler temperatur, trykk, fuktighet (relativ partialtrykk for vann), en rekke gasser (CO2, O2, O3, CO, metan og en rekke andre hydrokarbongasser)
Build an ESC (Electronic Speed Controller)
This video tutorial has a lot of theory in it. I've tried to explain all the steps that I've followed while building an ELECTRONIC SPEED CONTROLLER. The project last more than 3 months because I had to understand all the electromagnetic laws, check all the components specifications and design the board in souch a way that it would have all the desired requirements.
