This week end I repaired my own macbook air power cable ! I ordered just the broken lead from an ebay seller and it arrived just fine in a jiffy pack able to go through the letterbox so was awaiting my arrival. The most tricky thing was getting the white power pack open and using pliers in the unnatural way (outside edge of the square tips start closed then open to force apart the case) to open the thing . Noticing that there is little room in there once open I decided like you should to splice the new power cable to the old wires instead of trying to get to the PCB Printed circuit board instead.
Why do this ?
Well a new power pack is 69 pounds and this is throwing away a perfectly working pack it’s the wire that is at fault. The cable was 6 pounds and fitted perfectly both ends ie in my macbook air and the power pack. I was going to epoxy the power pack back together but decided that black electricians tape was a better option at least initially. Warning : Don’t use normal non electrical tape as power packs get warm and only electrical tape is valid. Tips:
Try to use a correctly cut piece of heat shrink tube to neaten the soldering joint. Use flux to get a better soldering joint. Most solders come with flux or buy separate it make sure the imputiues don’t cause a bad joint. Test the joint using your needle nose pliers. I also used pike disgorger that is a great tool as you can grip and fix the nose on the subject very handy in holding these wires.
Should you do this ?
The phantom 3 from dji brings quite a lot of new features and improvments across but from my own phantom 2 experience I want to tell you what I need and see if the phantom 3 delivers on that.
The phantom 2 would be incredibly hard to get steady meaningful indoor shots as the motion of the drone is going to be more random due to there being no GPS available indors - doh of course not !
The phantom 3 has the same underside camera/sensor recognition system so that it can feedback motion from the floor detail into the brain of the drone and correct - I would be keen to know if this also works outside to augment the GPS or if that is then just ignored.
A big issue for me is not having access to any video camera controls while in the air - we do have tilt control for the gimbal in the phantom 2 of course but now the phatom 3 brings in start and stop recording (how many times I have landed to realise that I wasnt recording I am ebarassed to say !) and there are some exposure contros I believe too. The software allows some further custom Tx (Transmitter) inputs for you to assign in the software. I am not quite sure what you would use these for yet.
