After around 12 hours and everything is cooled down, I manage to see the final result of my potting project. It seems like the pain has been well paid. The result is smooth as a delicious tofu. But after a very careful examination, I find a short crack. Not much, and definitely very tolerable.

Added: Duh, my mistake! I forgot to consider the top cover which has an elevated part a bit on the bottom side. So I think I need to melt the filler on the edge to compensate this…

If you haven’t read the first two post, then I would suggest to visit here and here first.

This is the 3rd experiment, and should be final one. I have done several experiments previously (although not published in detail here). So I have come up with final ingredients consisting of several natural materials.

So, let’s start cooking them!

Before I start, please be warned that this cooking way with open fire is not recommended at all! Use electric heater with controlled temperature or double boiler method. Most potting material (example: wax) has a flash point which could be ignited by the open fire. Although the flash point is quite high (few hundreds Celcius), but the temperature of open fire with gas stove itself could easily surpass those hundreds Celcius (hope you understand what I’m talking about). Never leave them unattended and never let them boiled even for a short time. Temperature would raise rapidly with such gas stove. Again, please do at your own risk!

All photos here were taken by my lovely wife As I have told you, I have to pay extra attention with this open fire technique.

Nothing special in here. Just showing a beautiful precision needle on one of my vintage Triplett meter. I wish most newer meter could have a similar passion to have such artistic and high quality build as vintage one.

This weekend, I play a bit off topic from my regular hobby, which is audio. This is an old HP Palmtop 200LX. I own several units but due to improper storage, the LCD is ruined. What a waste and sad news as I realized this few years ago. But what has happened just couldn’t be reverted back. Sigh!

Okay then, from a good friend somewhere in Makasar, I got a working unit (LCD included, off course) of this Palmtop. The chassis and everything isn’t that good, but I believe I have enough spare around as shown below. Then I start to disassemble and building a fully functional unit.
