( Using HI-NEST GS-18 Tweeters)
These pictures are from one of my students from Vietnam. He made this DIY Hexagonal Tweeter for his Swiftlet farm which locates at the Southern Part of Vietnam.
He learned it from my blog. He did a good job. He could just buy one from the market, which is made of Stainless Steel but prefer to DIY it. For him this DIY Hexagonal Tweeter is better that those available in the market which are made of Stainless Steel.
Reason................? Safety, last longer, protects farm equipment and dirt cheap.
For many people all Hexagonal Tweeters are the same, but to few there are totally different.
Why the DIY Hexagonal Tweeter is better (in all aspects) than those S,steel ones. Obviously cost is one of the main factors. With the money you spend on the S.steel one you could make perhaps 10-15 DIY Hexagonal Tweeters depends on what type of tweeters you are using. Best of all the DIY Hexagonal Tweeter has better advantages.
Metal , Stainless steel , Aluminium, etc are good conductor of electricity. When installed at the highest point of the farm it attracts lightning. Lightning strikes good conductor material to reach the earth. It is very dangerous and it would cost you a lot more when it damages the whole Swiftlet farm electrical system and equipment.
I often have readers asking questions why theirs Tweeters, Amplifiers, AC/DC converters,etc don't last long. And the above is one of the reasons they should look into.
The DIY Hexagonal Tweeter outlast any hexagonal tweeter on the market due to its DIY material used.
The DIY Hexagonal Tweeter' top is made of plastic . Plastic is a poor conductor of electricity therefore plastic trays are used. As for the pole, some of my students are using the hi-pressure PVC pipe, the thick one. The thickest they could find. The DIY Hexagonal Tweeter is light (plastic) unlike the S.Steel one thus the PVC pipe could support it.
Drill a hole on the tray. The size of the hole fits the PVC pipe and use 2 sockets, top and bottom to tighten it. It would hold the tray tightly or you may use some PVC glue to strengthen it. As you could see all materials used are poor conductor of electricity.
Now you could clearly see why this DIY Hexagonal Tweeter is superior. It is all boiled down to a clear understanding of Swiftlet farming, common sense,experiences,etc.
Sadly, many Swiftlet farming products in the market now are driven by "money motivated". People who made them, produce them are not Swiftlet farmer they are businessman. Many of them (8 out of 10) don't own Swiftlet farm. Many don't have the basic understanding of Swiftlet farming.
It is not surprising that you may know more than them.
Go and DIY one. Material need: 1) Plastic tray 2) Hi-Nest GS18 tweeters. 4-6 units.3) wood or plastic "L" channel to hold the tweeters.
Good Swiftlet farming All!
