DIY - Sight

It is sometimes good to collect waste materials for you to do something that worth to pass time. This broken glass piece was thrown away by a neigbour and I took it.

These two discs that I can produce from the broken glass piece. My tools are Oil Cutter and Sharpening stone.
Here I detail a bit how to get sight marks on the glass discs.
Fig. 1: Draw a pattern using a school mathemathical set.
Fig. 2: Get the discs together and place them on the pattern.
Fig. 3: Make 4 lines from edges of the glass to smallest circle of the pattern.
Fig. 4: Turn over the discs and draw '+' from the centre of the smallest circle on the disc ie the second glass of discs.
Fig. 5: Sight marks are drawned on both glass discs.

And here is just the Plumber's left over plastic material.
Fig. 1: Platic pipe.
Fig. 2: Cut a length of it upon how long you wish that you want your sight to be.
Fig. 3: Make 4 rings out of the pipe and these rings are use to lock the glass discs that to be place inside the tube of fig. 2.
Fig. 4: One ring is already placed inside the plastic tube.

The Sight is completed. It is a very simple sight. Effective?? You may try and make one.
Yeaaa...... the sight is now attached to the spotting scope. The sight can be positioned at the side or on top of the scope.
Here is a field test with the sight. An example here is a street lamp. With it can speed up your search for your subject.
Happy Birding.

Pied Triller (Lalage nigra)

After 19 days I am coming back to see the nest and find that Triller has a chick already. Looking at the size of the nest that probably this bird only lays and hatches one egg. Happy birding.

DIY - Shutter Release Adapter improvement

These are the cheap materials to start with to make an improvement and strong shutter release adapter. The long screw and square and round nuts are only cost USD 0.22. The small copper tripod nut I collect from my old spoiled tripod. I remove the hard plastic that covered around it and look like that.

The round nut is grinded to reshape so that two sides created on the nut. This is made due to nut too big and hinder from my Sigma to place on the camera adapter. The copper tripod nut is hammer in into round nut. Before you hammer the nut in, you have to screw in other short or long screw into Copper nut and hammer onto the end of short or long screw to drive in the Copper/tripod nut. This way nothing will spoil. The work is completed as in the picture.
Then as you can see some works are completed ie grinding on nut and sharp ends of square nut are grinded a bit bluntly and this nut is used to lock the long screw on to the round nut so that the screw stand firmly after you have screwed in the long screw to the tripod nut which is already inside the round nut.
Yeaaa it is ready to use now. Simple and strong. Fix it anywhere on the camera adapter!!!
Detail is shown.

The lens protrusion of this camera - CANON DIGITAL IXUS 980 IS - is short, and since the camera is so near to the eyepiece of the spotting scope, the Shutter Release Adapter is placed at the back on the camera adapter.

While here the Sigma lens protrude much longer and camera body is put at the back end on the camera adapter. Shutter Release Adapter is here at front on the camera adapter.
Ordinary tools are to be used for any works. The triangle ruler here is only use for checking the 90 degree vertically right of the Shutter Release Adapter.
Ahh these tools are always come together. You always need Vice when you grind.
After almost a day improving my shutter release adapter and able to successfully complete. My test is this White-collared Kingfisher or Mangrove Kingfisher where just infront my house. Good Shutter Release Adapter and no shake from it at all.
Happy birding.
