  • Bad Raven: Is the issue Turnigy or Turnigy Nano-Tech? I have found that mid-blue Turnigy tend to be low on their stated "C" discharge rating.

  • ched999uk: RaceDayQuads have some cheap but good batts out now. Josh B tested and stats say very good especially at price. HobbyRC have 1300mAh 4S just under £20. Not had luck with Turnigy lipos either!!

  • Reman: Just realised that I hadn't gone through my stored Li-Po's for about a month. I try to visually check them every Saturday, And prod the plugs with a multimeter about once a month. Todays seen 12 more bulging packs go out to the incinerator..... All but one was a bloody Turnigy! Part of me wan't to burn the rest now and just get a load more Tattu packs, But I've spent good money on these packs and wan't to at least get a little more use out of them. :(

  • Bad Raven: Pre MR's I used to buy a lot from J.Perkins. Their website showed all items and stock or due date, go to dealer and buy with confidence. Then they went all "lifestyle" and all the site had were pictures or people. I wasn't after people. I never bought again. Yes, you'd think they'd learn...........

  • ched999uk: Reman sounds like amazon search. I find it ok unitil you want to search by price then amazon falls apart.... You would think both companies would get it right...

  • Reman: It's strange. The original setup they had about 5 or 6 years back wasn't too bad (Except for them occasionally getting accounts hacked), But they changed it to the last one that was clunky and slow, Now they've replaced that with a flashier one that's also clunky and slow ?!?!?! Most companies learn from what they do wrong. I don't buy from HK half as much as I used to, Mainly because it takes forever to trawl through 100 pages of totally unrelated stuff while looking for something you were thinking about getting when you saw it there the previous week !!!

  • hoverfly: I don't think there is a search button on H/King. They updated the site and forgot to  relabel the search button with  Random bo##ocks..
    July 15, 2018, 09:47:35
  • Bad Raven: Agree - The Search is abysmal!!
    July 15, 2018, 08:40:52
  • Reman: I see HobbyKing's revamped their site again...... Shame they haven't made the search function work any better, Or worked out why the whole site goes slower than a pensioner in a Nissan Micra. :)

  • Reman: How thick is Google? You buy something online, Then for the next week you get targeted adds for the item you've just got?!?! That's the one item you're NOT going to be buying again at that point so it's wasted effort of there part. :)

Warning/indicator LED's and buzzer
« on: January 17, 2013, 19:20:24 »
Hi guys,
Isit possible to wire some LEDs into the aio pro board so that armed status and gps fix is easily seen , also a buzzer would be good?

Simular to this http://diydrones.com/profiles/blogs/led-low-battery-warning-on

Thanks
Paul

Hi Paul,

You can connect your own buzzer, but you have to be careful that you don';t overload and damage the FC board. This is why it says on the board plans not to connect a buzzer directly. The boards are normally 5v, the buzzer can vary but as an example might be 3v. So, there is a 2v surplus. You have to use Ohm';s Law to work out what resistor you need to use the buzzer. Ohm';s Law states Resistance = Source Voltage - Sensor Voltage / Current of Sensor. So, FC board is 5v - Buzzer 3v = 2v / Buzzer 10mah = 200ohm Resistor. You can put the resistor either side of the buzzer cables. Once you';ve done this, just enable the BUZZER code in your FC software. I';m in the middle of enhancing the standard MultiWii software to add tones and volume to indicate things.

Good luck.
