"VACANT" experiments.

My principle asked me if I could come up with some sort of system to let people know if one of our handicapped bathrooms was occupied.  I kicked around a few ideas and came up with this.  



Been awhile since I've used the printer so I fired it up...



Dang, the MM 2.0 is just tooooo fast. Let me slow that down a bit.








These were supposed to be test prints checking for size, but I decided they were plenty good enough, even running at 121% of maximum speed!


Here's the rest of the sign for the bathroom... Left goes on the outside, right on the inside.



Bar will go through a hole in the door, then the covers go over the dials and are screwed to the door. That way, you can tell from inside the bathroom what it says outside.



Inside:



Outside.



Little rough for a print, but again, I was running pretty darn fast.

Cleaned them up a bit with an acetone fuming,









Slapped some paint on the disks,



and gathered up all the parts.



Tried gluing in a clear piece of plastic to prevent kids from sticking a pencil in there and turning it from the outside... We'll see how long that lasts.



Drill a hole in a perfectly good door,



Put the bar in the front disk and slide it through,



and screw the cover on over top.



On the back:



Put the knob on,



and screw it's cover on.



There you go!





Guess we'll see if it works or not.  Thats the best part about the printer-  I can make changes and run off a new copy in just a few minutes.  Glad that I've been able to use the printer around the school for more than just student projects!

Airing out the Z50's...

Man, I have got to do this more often.  The boys have been driving me batty asking if they could do this, or this, or this, or this, or this, or that.  Time to get them OUT OF THE HOUSE.  They finally asked, very half-heartedly because they knew the answer was going to be no-  "Can we get the dirt bikes out?".  SURE! 

Trusty old Honda's fired right up and away they went.  I could tell they were going to get bored with the standard loop down the road so I let them add a 'round the house loop.


Didn't take long until they were bending the last corner pretty hard so they could hit the "jump".







Yeee-HAW!







Oooopss... Little TOO fast on that corner with the wet grass.



Who knew? The front fender of a Z50 can be used as a plow in a pinch.



He got back on his horse though.





Might have to load 'em up and head to the Rose pond again. That was a lot of fun too!

Leftover Printer Projects.

So I found a few pictures from my tech 2 class from last school year.  Thought I posted them already but apparently not, so here they are.

I gave them a pretty simple set of directions:  Design something in Sketchup with at least 3 different parts, one of which must "move".  I had several kids try and do cases for phones and ipods, but they proved a little to detail rich for most of them.  Here are a couple that I managed to take pics of before they left for the year.

Airplane.  Printed in several different pieces then assembled with glue.  The propeller spins!





Ipod charging stand.  No moving parts, but very functional!



 

Lego guy and a robot.The one on the right has moving arms.



Turntable.  Tried printing rollers for it but ended up using ball bearings.



f
And a couple of pics while on the printer.


 


 

There were several others, but I didn't get a chance to take pictures of them.  Had a couple of R/C winches and a really cool bicycle with spinning wheels and a working set of handlebars.  I'd like to reprint that one for my classroom sometime.

Just for fun, a few from today.  Making an "Occupied" sign for the handicapped bathrooms at school.  Cranked up the speed, man is that thing fast!




 
 

There you go.  I'm sure we'll have plenty of projects to post in the coming months!

IGSBEP- are you doing it?!

Well, I made it through day 1.  Its all downhill from here, although I can't decide if thats a good thing or a bad thing.



Helping my wife decorate her room got me to thinking, my room has tons of gadgets spewing forth from every corner, but it could use some more "artsy" informative decorating.  Spent some time and made the big IGSBEP banner and hung it up on the wall.

A year or two ago I had a bit of a breakthrough-  Seeing as how there are no specific state standards that really dictate what I'm supposed to teach, I figured I could do just about anything.  Probably shouldn't admit this because I'm sure some well intentioned fool will eventually find *something* that I am *required* to teach.  Not that I have a huge problem with that, but in my case it would have stifled a really good thing.  I sat down and thought about different overall themes I could teach about.  I settled on the Design Process.  It fit perfectly with the projects and tools I already had and is applicable everywhere.  Interestingly enough the design process is almost identical to the steps used to write a report in English or test something scientifically with the Scientific Method.

The best part:  You can use it to solve ANY problem.  For example, before ISATS I would sit my classes down and explain to them that during the test and in life in general- you will come across problems that you don't know the answer to.  Does that mean you just guess? NO.  Does that mean you just pick a random answer? NO.

Take a minute to IDENTIFY what specifically the problem is.  Once you have a good handle on exactly what you are being asked to do, GENERATE some ideas.  Sketches, different possible directions, whatever- just let your brain vomit (yeah, my students love my imagery) random related ideas out on the paper.  Once you've got a few, SELECT what you think is the best one.  Is it right? Who knows?!  Lets find out!  BUILD it.  Try it out.  Most important on this step- don't be afraid to fail.  If it doesn't work, try something else!  The next step is sometimes hard to seperate from building-  you EVALUATE.  Did it work, did it work well, if it didn't work why not?!  You might need to go back to generating new ideas to try more options.  Keep trying.  Once you have a viable option, PRESENT it.  Sometimes you might need to present it even if its not right- ask for help.

Whew.  Little long winded there but now you know what the IGSBEP is. My point is this:  students need the ability to SOLVE PROBLEMS, not just by rote spew facts out correctly.   There is a place for that too, don't get me wrong.

Hopefully, I can help my students be able to solve problems that come up not only in my classes, but in English, Math, Science, etc, and most importantly, life in general.

Hope all you teachers out there are having a great start to the new year, and remember, keep your stick on the ice!





p.s.- just for fun, the birds eye view of my room about 18 feet up when I was hanging the IGSBEP up.  Kinda messy, was still putting things away and my room was being used to build stuff for a parade float.





And one of the awesome morning views I get from my classroom.  *Love* my job.

Labor day- One more Iron in the fire.

Tried my hand at forging a knife this afternoon, since I needed another project to work on.

I made a knife in Grade 9 Industrial Arts class and loved it. Knife turned out okay, but remember, I was a 9th grader. Fast forward 20 or so years. Now I TEACH "Industrial Arts", and while they won't let me have the students make knives, that doesn't mean I can't!

Been thinking about doing one for a year or so. Then I discovered that the school has a little electric kiln oven stored over in the wood shop. AND, I've got several old Nicholson files that are pretty much useless as a file anymore... Hmm.

So today I decide to attempt some blacksmithing. Something I've never really done but have always wanted to try. What's not fun about red hot metal and big hammers!?

Lugged the kiln over to my room, plugged it in and fired it up. Let it bake for a bit while I smash some metal.

The file:



Welded a chunk of rod to the end so I don't have to mess with tongs.



My setup. I don't have a forge, period. Turns out a rosebud works pretty darn good, although it sure got warm in the welding booth...




So I read a bunch on the interwebs (including a bit here on advrider) and watched several u-tube vids. I should be good to go, right?!

Get 'er good and hot,



and start pounding. Really have no idea what I'm doing, so I'll just pretend.



Not your typical knife blade. It'll make more sense when I start to clean it up. I hope.



Pounding the bevels was dang hard. Got it sorta close and called it good enough. The rest will be done the, uh, old fashioned way? Er not. You know, with a grinder and a file. Not the reaallyy old fashioned way, like blacksmiths used to do. 

Here she is fresh out of forging. I stuck it in the oven and let it cool slowly for about 1/2 hour. I know thats not long enough to anneal it, but I'm experimenting here...



Cleaned it up a bit with an angle grinder and spent some time filling it. It's definitely soft enough to file, so I guess thats good enough?!



And a bit more with the sander.





Probably going to leave the crosshatch on the upper part of the blade. It still has a ways to go, need to clean up the plunge cut on the bevel near the hilt and I want to put a short edge on the outside of the "beak". More to follow, eventually...
