Pocket Pellet Stove


My little Smokeless heater




Being inspired by the cold weather
I began tinkering on an new idea 



I wanted a portable self contained heat source 
that could fit in a backpack 





As always I scrounged around until I 
found what I hoped would be acceptable
components, in this case it turned out to be
scrap sections of a metal fence, some old
screen from a rabbit hutch and a soda can  




I drilled then taped the holes to except the legs
 cut an opening on top for the flue then had a friend 
weld it together
"Thank You Aaron"






I started testing with a handful of wood pellets
and was surprised it lasted almost half
an hour. By restricting air intake with the
top of a soda can I was able to increase the 
temperature when using pellets
Note: I did use a propane torch to lite 





As long as there were flames it put out very little smoke
The addition of stovepipe could make this
a nice little tent stove

The Principal's office chair

A nice additional to the house


I seem to recall sitting in one of these chairs while
waiting to see the elementary school principal 

After the tear down and sanding I began refitting 
the parts




I had to use some creative clamping methods
due to the irregular shapes


and more creativity in clamping 


 here I used a second bar clamp 
to keep the frame square

Rupert the Walking Wooden Robot



Here's a fun weekend project. 


Rupert the Wooden Robot
Animated 




An earlier design



You don't need an engineering degree to build your
own walking robot. I copied the dimensions from this site 
on the Theo Jensen leg design. Adding my own
design concepts to the Jensen leg this is what I came up
with  






The first concept had great potential 
but I was unable to get him to walk



Seeing a need to enhance the design and
reinforce the leg connectors   



I cut him in half



And gave him an articulating 
mid section in hopes to solve
 one of the many issues





 Here is some of his first steps 





Now that I have a proof of concept design,
I'm encouraged to build a bigger and more
refined version of Rupert
