FLIR ONE Pro - Inside Uses

Oven-baked spaghetti looks innocuous at a casual glance

Indoor uses of thermographic imaging camera include finding leaks of heat or water, owing to the fact that people doing repairs may have the budget and the repeated usage that justify owning such a device. But as the cost to buy one goes down and the size becomes small enough to carry in a pocket, more uses come up. The one I found useful in raising kids is cooking and food safety. As you can see here, a bowl of spaghetti straight out of an oven didn't look particularly dangerous at first...

But the bowl is quite hot at over 85C, enough to cause a burn

But with FLIR ONE Pro, you could see that the handle was quite hot. The spaghetti itself was also sizzling at over 70C. This image served as a good way to teach my kids why they should be careful with a bowl that came out of an oven.

Makibox Trial & Errors

Unintentional cutaway views of the printed squirrel

The designers of Makibox aimed to reduce the headaches of using a 3D printer, but it does not mean it's trouble-free. In fact, there can be some problems because you're dealing with plastics, a tangible material.

One problem I've encountered was a leaky hot-end nozzle. Specifically, it's leaking where it's not supposed to, on top of the head. When the leak grew too much, the printer tended to stop printing. The incomplete squirrels shown here are such results.

Melted black plastic oozes out at the top

Thankfully, I had a spare hot-end, and that worked without any problems. The leaky one has been sent back for another replacement. With this problem out of the way and printing as much as I would like, I noticed another problem creeping up.

Printing toys with Makibox

So this printer makes my toys now?

A home 3D printer has myriad of uses, but I think toy printing immediately stand out if you have children. Makibox can print in non-toxic (after printing, anyway) ABS polymer, so I set out to make a simple plastic figure for my daughters after the test prints were done.

One thing to note is that the extruder broke down a few weeks ago, so I had to send it back to Hong Kong for replacement. That's why there had been a lack of blog posts about the 3D printer since early January. I've got my replacement, and it works perfectly so far. Better than the original one, in fact.

Makibox prints a squirrel

I selected a squirrel design from Thingiverse because it didn't look to complicated, yet cute enough so that the kids would like to play with it. It turned out that I was right on both accounts. Keep reading for more pictures.
