Homemade FPV monitor

Hi guys, I wanted an fpv monitor that had a receiver built in. 
Looking around online there’s some for around $100ish but I already had a spare Sony LCD meant for a reversing camera, and a spare RC832 so I


 figured I would give it a shot !
I disassembled both first, and was pleased to find a little free space in the LCD. 

I positioned things around a bit and used a sharpie to Mark things out to get an idea of if this was feasible. 


It looked like it would work !

The cables it had were huge and thick and had multiple connectors and Yada Yada I didn’t want all that so I just soldered to the convenient break out connector !

I did some final position testing and drilled some holes for the buttons and antenna connector, also drilled a hole and filed it a bit for the LED display on the receiver to see which channel we are on. 

Hooked it up and tested everything before routing the power cable through a hole, the hole I drilled inadvertently had a connector right in front of it when ibsealed up the case, this conveniently served to compress the cable and provide strain relief!! (The connector was unused anyway!)

Everything sealed up and working !

Crude holes but meh they work !
It has a tripod screw hole in the bottom and that slot for mounting. I’ll sort something out to mount it later. 

It has the option to disable blue screen so I can always get as much image as possible even with low signal !

Runs off a 3s lipo. 

Not much room inside for anything else or I would have tried to fit something inside to power it…

Picture looks great ! It’s super bright so should be visible outdoors well enough. 

Das me

That’s all for now ! 

Hubsan lives!

I retrieved my Hubsan X4 from its graveyard recently, here’s a few photos showing the condition it was in.

Amazingly, it still flies!
Even after being rained on.

Missing a prop

Looks like that motor was pulled out with the prop :0

That poor leg is pretty messed up

The original battery, when I connect it the quad lights up for a few seconds as normal, maybe the protection circuit cut the power before the voltage dropped too low?

The motors escaping!

This is the only 1 cell battery I had D:

It powers up!

It works omg šŸ˜€

I’m actually impressed it survived a week in the sun and rain on a metal roof šŸ˜€

I’ll update soon with the footage from the SD card if it’s in tact.

TBS Discovery Pro Restoration

Hello!

So this post is going to be basis for a number of updates, essentially I picked up a TBS Discovery Pro quadcopter off ebay for $200 in pretty crummy condition, and im in the process of restoring it to its former glory.

This post is where I will be posting my progress on this, as well as to reddit but eh, this is my turf.

So just for backlog:

Here’s the eBay item page:

Here’s two threads on me trying to identify damaged / broken off components:

So I am restoring this quadcopter….

Can I just take a moment to vouch for how incredible isopropyl is at cleaning these boards? just look at the photos and see for yourself.

Here’s the auction win screenshot:

Finally, here is the album of the photos of my initial disassembly / the damage.

The hardest thing for me is going to be replacing the I2C port on the Pixhawk…

I really don’t know if I can do it, and im worried I’ll mess it up even more..

 

If you’re great at tiny soldering please hit me up if you can help!

The SD card, IĀ WAS able to pull flight logs and data from it, but I won’t post it here because it probably reveals the location of the previous owner’s home..

From the electronics I have tested, it appears to work, and the telemetry is a 433Mhz 3DR system. (I confirmed later by removing the heat shrink.

The gimbal motors need replacing, and the main motors need new bearings, the I2c port needs replacing, and the receiver needs its antenna to be fixed or replaced. The top board MIGHT not work, I cant test until the gimbal is repaired. but that would be around $220 to replace im told.

Once these are done, I am confident it will fly once more! (oh and two props are fecked)

Ill also need a new telemetry module, as having one isn’t very helpful šŸ˜‰

The USB port on the Pixhawk was pretty crusty and unreliable, but ordered this and connected it up and we’re back in business!

As I mentioned at the start, Ill update here when I have more to post!
