MAKE a red-dot-sight mount for point-and-shoot camera

Bird photography enthusiast should find this post useful. It's about getting a red-dot-sight in Singapore (not illegal), then making a bracket to put the red-dot-sight and camera together. The cost for this project is around S$100.

I'm a photography dummy who doesn't own a DSLR camera, and this was my situation. To take photos of birds, which usually keep their distance, I bought a point-and-shoot camera (Panasonic DMC-TZ70) with 30x zoom factor. I had a hard time aiming at the birds at high zoom and just when I started to regretted buying this expensive camera, I chanced upon a online post about this issue. I emailed one helpful poster, Mr Erik Ohlson (thanks!), about how to make a bracket to attach a red-dot-sight for my TZ70.

The main obstacle about making this bracket is that I live in Singapore. There isn't a Radio Shack, Walmart, Bunnings where I can get the required parts easily. I also don't own a car, making the search for parts across Singapore really painful. The following guide is my solution for my specific problem. If you intend to attach a red-dot-sight to a DSLR that has a Hot Shoe, the solution is much easier. I will include this at the end of the post.

The photo below shows the bracket I made. Both the camera and red-dot-sight are removable from the bracket. In case you're wondering, the white stuff underneath the camera is not Plasticine - this is a sturdy bracket that I'm able to used under the hot sun.

Ensure you have all the items in list below.

The photo below shows some of the items in the list above, in case the description above is non-obvious.

The photo below shows how the items comes together to form the bracket.

Step 1: Measure the red-dot-sight and camera. This is to determine the length of the brass sheet to cut. The measurement shown below may not work for you. Naturally you would go to hardware shops to buy metal sheets, but for weeks, I found none. In the end ArtFriend that sells arts and craft materials is my friend. Who knew?

• Mark on the brass sheet, on where the camera, its tripod screw mount hole, and the red-dot-sight should be at.
• Leave 1 to 2 cm buffer between the camera and red-dot-sight.
• For me, I cut the brass metal at 12 cm length. 
• Then cut off 3 pieces of acrylic triangular rod, each with length 8.2 cm. 
• This was done with my old cheap handsaw with different blades for cutting metal, wood and plastic. When sawing, always wear safety goggles and have another person around, in case of accidents.

Step 2: Assemble the 3 acrylic rods with super glue, to make the "dovetail rail". It allows the red-dot-sight to clamp onto it. Ideally you should get a small aluminium rod and file it into a dovetail rail. It was really difficult (maybe even impossible) to buy a single piece of solid aluminium rod in Singapore. This work around is a good solution for me. Super glued acrylic rods does not seem to have heat expansion problems under the hot sun. After assembly, check that your red-dot-sight is able to clamp onto the acrylic dovetail rail.

Step 3: Find a friend who has access to a workshop with a drill press. Drill a hole in the brass sheet, the size should be 1/4 inch or slightly larger. It was really difficult to find anyone with a drill press/ workshop in Singapore, since the majority of us live in small apartments. Do not use hand held drills, what you need a proper, steady, heavy drill press like those you find in polytechnics technical workshops. Again, wear safety goggles and have someone around when drilling.

Step 4: Cut a section of the stool leg rubber tip off, poke a hole on it, such that  the D-ring screw can go through it. Check that the D-ring screw is able hold the camera and brass sheet together in a tight fit.

Step 5: To ensure that the camera does not move around when screwed in, we should add epoxy to the brass sheet to hold the camera in. Extend the camera to the maximum zoom, then cover it with cling wrap (I used 2 layers), D-ring screw it to the brass sheet. Apply some epoxy putty around the edges of the camera such that you are still able to remove the camera afterwards. Removed the camera and let the epoxy cure/ harden for 2 days.

Step 6: Super glue the acrylic dovetail rail to the brass sheet, use a few layers of super glue for more strength (.i.e. dry, coat, dry, coat). And that should be it. Put the camera and red-dot-sight together on the bracket, calibrate, and happy shooting.

If you have a DSLR camera with a Hot Shoe, you can purchase red-dot-sight with a Hot Shoe adaptor. I saw this on Amazon, but I can't confirm if it does indeed comes with the Hot Shoe adaptor/ camera mount.

Alternatively, you can download a 3D printer STL file of a Hot Shoe adaptor for red-dot-sight, and get it printed at any local 3D printing company. They offer 3D printing in plastic and metal. I myself have not try this.

FIX sticky rubber on Gillette Mach3 handle

The rubber grip on the Gillette Mach3 razor handle will become sticky after sometime. This post will be about fully fixing/ repairing this. Initially I tried to scrap off the thick rubber, creating a big sticky mess (it won't come off easily). While doing that, I noticed that the rubber is are actually made up of hard plastic parts (coated with thick rubber), snap-fitted into the metal body. This suggest that the thick rubber parts can be cleanly and fully removed.

Tools I need:

• A pair of scissors with a small sharp tip.
• Pair of safety glasses (always good to wear one when fixing anything because lab-grown human eyeballs are currently not mass-consumer products).

The handle is made up of the rubber grip and the metal body. The rubber has become soft and sticky. See image below:

Look for an opening between the sticky rubber grip part and the metal body. Insert the tip of the scissors into the opening. The carefully/ slowly pry them apart.

The main part of sticky rubber grip is removed.

For the smaller parts, each has 3 “snap-fit joints”. Use the scissor tip to push 1 joint upwards. 

Use the scissor tip to push the other 2 “snap-fit joints” out sideways. Then remove 3 the rubber parts.

All 4 parts of the sticky rubber grip have been removed. Look at the amount of dirt in there, maybe this product can be made more hygienic if the whole handle is just 1 single piece of metal.

Scrub the metal handle with soap, dry it before use.

I find the metal handle by itself is sufficient for me to get a good grip. Sticky rubber handle fixed.

BUY cheap disposable foam earplugs

If you often use disposable foam earplugs (good for studying, sleeping), getting them from the local pharmacy can be costly. I chanced upon this bargain deal.

Of the various disposable (sorry mother nature) foam earplugs I purchased, this is one of the most value-for-money: Jackson H-10. One box of 200 pairs at $37.45. One pair can last me up to a whole week and one box up to a couple of years and ears :)

Alternatively (e.g. Jackson H-10 ran out-of-stock), get the Elvex uni-fit EP101, 200 pairs at $34.24.

The company I purchased from is PSE Safety Corporation Pte Ltd. Their customers are mainly businesses rather than individuals, but I have been buying a box from them every couple of years. They also have nice looking plastic safety glasses that looks like Oakley sunglasses, for around $10, which I also bought a couple.

Do avoid their lunch hour (I think it was 12pm to 1pm) and browse their website for the safety glasses' code number if you intend to get them. Some glasses listed on the website might be outdated (not sold anymore).
