Fabulous Found Tools and Materials

Things a bricoleur needs / wants / desires



Chopsticks    [ 777chopstick 777chopsticks ]

chopsticks make great mixing rods.  They work great for holding a nut that has been painted and is drying.  they work for proving connecting rods.

I came, I saw , I unplugged the toilet ..... clogged toilet

99Toilet issues

The upstairs guest toilet got plugged by JY poop.  
I had configured the toilet for vigorous action including extra water
so the toilet overflowed. ,  The plunger did not fit toilet well and
I could not clear the poop. Finally I used an old towel as a gasket…. I cut a
two inch ( 6 cm )  hole in the middle of the towel and laid it in the middle of the bowl.
I put the plunger through the hole. I used another towel to “roof” the
plunger to reduce splashing.

When using a snake … protect the toilet from scratches …….   use a bent plastic pipe

It is also a good idea to use dish cleaning soap …. Followed by hot ( not boiling ) water.  
Water that is too hot will crack toilet.

Investigations into SQ13 , SQ11 , etc. cameras ... review

SQ13 cube camera and DVR 

Disassembly of SQ13  ( teardown )
reverse engineering , 
see the following images ....


SQ13 Audio
Audio recording is not very strong.  The microphone is in what seems to be a disadvantageous location.

SQ13 Battery
It appears to have a protection circuit as part of the battery.  The battery is rated at 3.7V and 300mAh.  Any add-on battery should have the same.


Disassembly of SQ11 ( teardown )
SQ11 images

SQ11 Battery
I saw no markings on the battery.  It is probably a 3.7 volt lithium. It appears to have a protection circuit as part of the battery.  Any add-on battery should have the same.
