Adjustments for GoPro lens hood

Made a few adjustments to the original design to help avoid the lens hood being in shot. Shortened the snood so its will be both wider and shorter.

Lens Hood fitment

Lens hood will beed a few small changes just to make it fit better bit a few mm off each end will do

GoPro Lens hood

Decided to work on a lens hood for the GoPro to stop any issues with polystyrene coming lose around the exit hole on the payload.

When i made the hole it was no way near as good as the on for the RX100 and ended up also digging away to get a wide enough aperture so that the wide angle of the lens would not catch the outer edges of the hole. I'm a bit worried that i might get bits on the lens or coming lose during flight.

So a few minutes in OpenSCAD and i came up with

Its printing at the moment so will see what its like in about an hour.

Payload taking shape and almost compelete

Bit more work carried out on payload and started to mount camera etc within. The 3d printed parts have mad wit very easy to remove items etc while i get things ready.

Both the Sony RX100 MkIII and GoPro are mounted on 3d printed parts that allow me to remove the items as required. Also allows for easy routing of the dummy battery for the Sony.

3D Printed Hole Saw

Been constructing my next payload and it came time to make a hole for the camera lens to see out. Don't own any hole saws and decided to give making one on the 3d printer a go. I could make it any size i wanted.

NTX2 Radio working with Arduino UNO

Made some good steps forward today with getting my own HAB tracker up and working. Using a number of items i already had from other projects i managed to get the NTX2 radio module transmitting and picking up a signal from a GPS module.

I then went on to add a BMP180 module to act as another sensor i could practice adding into the telemetry broadcast back through the NTX2 radio.

So far have the external temperate added to the telemetry data.

Took a bit of doing but slowly understanding changing  between variables and working with strings. Still need to work on ensuring things like flight mode kick in on the GPS so it works at high altitude.
