How To Unlock Step Files In DesignSpark Mechanical

DesignSpark Mechanical is my current go to program for design.

It is solid modelling and easy to use.  It has its shortcomings as it is a neutered version of SpaceClaim.

However one thing that kinda irked me was the inability to import step files from solid works or other solid modelling programs.

This changed awhile back when I discovered this trick.

Now you still can not export these files to share as solid without the 1000 dollar add on, but it really saves the headaches.

First of all you import the solid file.

Here we used a foregrip solid model file from the famous Warfairy.

If you right click on the object tree, you will see that there is a padlock and the lock button is greyed out.  so you can not unlock it.

to fix that, you need to select a plane, anywhere and draw anything, just a square or surface.

Once you go back to solid view, you then move that item to the folder in the object tree on the left.

Once you have that unlocked object there, you right click again on the folder, and the unlock button is not greyed out and you can unlock it.

For complicated assemblies, you will have to move that object you created to each locked folder and repeat.  Then delete the object you drew

 For some of these operations I had to photograph the screen as the screenshot function would close the window i was trying to capture.

Next Generation Batteries

Awhile back, I was introduced to the work of Robert Murray Smith and his YouTube channel.

I was searching for a way to make a conductive ink for my solar cells.

Along the way, my mad scientist Facebook group members also mentioned the guys work and apparently guys in my mad scientist group know him.

As far as subject matter and presentation, he really explains this graphene thing quite well.

I have included a couple links down below so you can see the video from a couple hours ago.

In it he demonstrates making a battery with ordinary materials.  Paper, scissors, paint brush, carbon powder, glue, etc.

Free Graphene

I have a batch of my latest graphene available for free.

It is pre-doped with sodium carbonate electrolyte to use in making super-capacitors or graphene batteries. It is from one of my projects and I made a lot of it.
Just pay the shipping from the tropical island and I will toss 20 grams of graphene in DHL.

You can go to DHL and get the rate for yourself with the following info

Origin is Antipolo City, Rizal Province, Philippines  Postal code 1870

Container size is 10x10x10cm and 100 grams.

It is so light weight this will get you the minimum charge price for volumetric pricing.

Limited to the first 200 grams and before November 1, 2017

message me on facebook  or thru the message box on the side of the page

Twenty Dollar Wind Generator

Over here on the tropical island there are these cheap small ceiling fans for sale.  usually they are between 7 to 15 watts and sell around $4 or $5 max.

I saw recently a guy who converted one to a wind generator on my Sunday experimentation day.
I usually take every Sunday and block it out as my day each week to work on something interesting, study something or conduct some experiments.

So when the wife went to work, I tagged along, and hit up the local equivalent of the 99 cent store.

I picked up a 10 watt and 15 watt model, along with a 3 watt AC LED trouble light, like the type mechanics use.

Total with transport I spend less than 10 bucks.

dont mind the dirty floor, its fiberglass epoxy from my micarta projects
I eagerly took it home and proceeded to make one based on the youtube video.

Sadly I do not have enough wind to make it work well as is.  I need a bigger wind prop.

I investigated the vertical design, but I found that it will be too expensive to 3D print the airfoils.  I had my son the aeronautical engineer in training draw them up for me. Sadly thought the 3D printed airfoils were going to be too expensive and take days to print.

So I went back to the drawing board and came up with using just regular plywood laser cut for the props and some 3D printed adapters.  This is much cheaper to make and simpler design.

I also experimented with ways to convert the power to something usable.  The output of the generator when spun by hand is between 60 and 300 volts depending on wind speed and load.

The ceiling fan will generate electricity as is without any mods to the motor iteslf aside from sealing it inside with clear acrylic paint against the weather.

The wood props I will just heavily coat in varnish and the cheap plastic parts I will spray paint white to protect from UV degradation.

I am not sure about the bearing life as of now.  It may need disassembly and a sealed bearing added in the future.

So to convert the power, I have come up with using a basic 12v power adapter.  I have found that the voltage regulator of these cheap 100--240v AC to 12v DC adapters work just fine even down to 40 volts AC input.

They are a $12 item for 6 amps and around $5 for 2 amp like a CCTV adapter.

Next stage is to design some sort of commutator for the wind generator, laser some wood foils, buy some PVC plumbing parts, get a amperage, voltage, and watt meter along with a light to serve as a load.

I am a bit short on cash right now to get it done this week, but if you want to help out,. I can finish it all with proper documentation for about $100 dollars if you want to help out.

I had a windy mountainous area for testing and a guy ready to monitor it for a couple weeks.

I will take donations...
