ROV power board
24. May 2013 15:12 by Jens Willy Johannsen Categories: Projects
Here are Eagle schematic and board files as well as BOM for the ROV power board.
I moved all the high voltage/current stuff to a separate PCB and separated the control connections by using optocouplers.
That should help avoiding the electrical noise from the power MOSFETs switching at 20 kHz for the thruster motors.
BOM
| Amount | Item | Spec | RS no. | Comment |
|---|---|---|---|---|
| 1 | TE Micro-MaTch 12 pos female | 6804978 | Or just solder wires directly to the board | |
| 1 | TE Micro-MaTch 12 pos male | 6804993 | ||
| 1 | 12 lead ribbon cable | 2899852 | This is actually 14 leads. Peel off two or use separate wires. | |
| 6 | IRLS3034-7 MOSFET | 6887257 | ||
| 6 | FOD3180 optocoupler DIP-SMD | 6712706 | ||
| 7 | Screw terminals BLK | 4813989 | ||
| 7 | Screw terminals RED | 4813973 | ||
| 6 | SMD diode | S5BC | 7514821 | |
| 6 | SMD capacitor | 100 µF | 7472871 | |
| 6 | Ceramic bypass cap. 0805 | 0.1 µF | 6480979 | Or any other 0.1 µF 0805 ceramic cap. |

2 comments » Great reply to the “3D printed gun” media frenzy
7. May 2013 15:03 by Jens Willy Johannsen Categories: 3D printing
The past few days, the media have been having a field day with the "now you can 3D print you own gun" story. (Here on BBC for example).
Do yourself a favour and read this comment on Hackaday before you join the choir…
