Cleaning horse rugs

Now that it’s winter horse rugs start appearing on the front porch, they are left there for my attention – to clean.


I use a small GMC pressure cleaner connected to the water tank.

Snowflake and Trixie Bell

Snowflake and Trixie Bell - RIP

Panasonic 26" CRT TV



Purchased this in 2005 and its still going well.

Was moved from the lounge room down to the rumpus room (store room) where it sat in a corner when it was replaced with a Panasonic 42" plasma.

Found a new lease of life when it was lugged back up the stairs and into NJ's study to replace the Tevion 51cm CRT. Nothing wrong with the Tevion, the kid needed more AV inputs for all her entertainment stuff (Tevion only has one AV) which the Pana has.

Fish tank modifications

Fish are out and mice are in, so my older kid MK wanted the fish tank modified.
Job was to replace the hinged timber top with wire mesh.
So I made up two pine timber frames and stapled on cage wire.

Makita battery pack - continued



 Basically we want to end up with a modified battery pack physically the same as before but with a decent figure 8 flex running from the bottom (offset to allow clip to close) and about 2mtrs long with battery terminal size alligator clips at the end.


 


To drop the voltage down from 12 to 9.6 we can use a few diodes.


We need to loose about 2.4V (12 – 9.6 = 2.4V)


 


Voltage drop across a silicon junction is 0.7 volts so:


3 diodes = 2.1V


4 diodes = 2.8V 


 


However, we need to make some practical measurements…a full charged lead acid battery in good condition stands at 12.6V but most likely we are going to be using an old 2nd hand one with a lower terminal voltage.


Another new toy for kitties.
