I built them but you can buy them prebuilt. They may even come in a nice little box with a bow. :) They splice into the video line and add the on screen information. Psst: You can build your own MK boards also. ;)

I think that is an old version of an EPI-OSD board. I built two last year. I'm going to use one in the ground station and sell the extra. Kilby: Good flying for an early flight. My second FPV flight in the KK Quad landed upside down due to a technical difficulty at 30 some feet. ;) BTW, I was...

I've never had a problem upgrading. I will say this though: I don't particularly like being the first to test new features. ;) The order I used was: Take screen grabs of old settings Unzip MKTool to it's own directory and change to proper com port screw around for 10 minutes figuring out why my...

Typically, the BL-Ctrl code will remain the same unless they find a bug. It's a real PITA to upgrade anyway. The Compass firmware won't change much either. The majority of the code for the new features resides on the Navi board and the FC board has to get minimal changes to accommodate the...

I'm working on a bad MK BL-Ctrl that I believe caused another problem. The schematic below is for the FET section. Can one of you electrical engineers tell me what would happen if R25 was to fail. Kirk Edit: I should have been more specific. It's a version 2 BL-Ctrl. I know R25 will stop...

No good. Much too close to Double Visions to do any safe flying. :p

That is a little known 'feature' of the firmware. That got me thinking - was the MKs reaction similar to when you had the problem with the SD card? BTW, Another thing you don't want to do is to click 'write' in the settings screen when in flight.

Can't wait to see the build Mat. I have faith and I'd have the boards in my hands if I had enough time. Do you know if it can handle a dual prop copter? Bart, the terms 'Pirates' and 'clone' don't have the same connotation as one would think. Arduino based 'things' are by nature shareable...

Files on the card will cause that warning. Is that the card for the Navi or a camera card?

Cool idea. I didn't know those things existed. I was thinking about getting one to try but the thought of having a 2.4Ghz wifi transmitter near my 2.4Ghz control RX doesn't seem safe. I will try one after I move to a long range UHF radio system.

What have you done? Did you check that it's on the correct com port? Connect the MKUSB to the computer, start MKTool and change comports until you get a flickering red light on the MKUSB. When that happens you know that MKTools is trying to talk to the bird.

Here's one I fixed yesterday. The solder should flow through the hole and leave a fillet on each leg. The cap leg soldering on an MK distribution board and BLC is extremely important. In a worst case, a bad joint will bring the craft down AND fry every microchip on the I2C bus. Do yourself a...

The .de forum is the only place that the developers of the navi code will learn of the problem and fix it. I would make a post but it's second hand info. They would want to hear it from the horse's mouth and maybe even inspect the card. Or maybe you can email your MK supplier so they can...

That is pretty interesting. This is a problem that I would post on the .de international forum to get Holger's attention. It appears to be a bug or bad programming that they need to fix in the navi code. There is no way that writing a log entry should interfere with flight. Please double check...

Good idea. Is that the one with the built-in cup holder? :p

The LEDs are nice as a low battery warning if nothing else. It's not that hard to wire but there are several options depending on the current flow necessary and whether one has a distribution board with the transistor circuit. I don't have such a board so I soldered together a transistor...

Sheesh.....that's nothin. I once climbed to the top of one of the largest drag cranes in the world and drank a beer with my feet dangling over the edge. :rolleyes: Seriously, how does anyone top Ted's excellent adventures? WOW! A few years ago I spent my off days being a hang gliding bum. I...
