Circuit board Actual size 1:1
Assembling
leave enough of the legs on the chip to bend
over the board and spray the board with a protective lacquer
secure the network cable using a small piece of wire
Slide 1 is showing the finished temperature probe.
Slide the circuitboard into a tube then fill the tube with a waterproof Silicon sealant
Slide 2
I have secured the cable by using a small piece of copper wire
Slide 3
All components are mounted I used a small piece of shrink wrap tubing
on the cable end
The casing used on this temperature probe is a large marker pen
please wear disposable gloves
Remove the plug at the bottom of the pen. I used a small screwdriver
to prise the plug out
Remove the ink cartridge dispose of this carefully
pull out the tip of the pen using some pliers
I use silicon sealant to seal top and bottom
At the top where the cable comes out put a small piece of heat sink tubing
And sprayed it black. As you can see, it makes an excellent casing for this project
