Battery dispenser v2

Battery dispenser v2
The good old battery dispenser i made earlier needed an upgrade. And since i got now a 3D printer i took a slightly different approach.

Moon city

Moon city
This print i had on my list for a long time already but never came to it. While being 'between two projects' i descided to give this one a go and see what the result will be. It came out without any cracks however i still had to do a lot of cleanup. I spray painted it with glittering aluminium paint. Next i drilled a hole in the bottom and installed a multi color LED from a cheap Christmas ornament. It will cycle through different colors all the time.
This moon city can be found HERE

Sundail watch

Sundail watch
The fun thing of 3D printing is that you can bring so many ideas to live such as this watch.
Does it tell time.. mwah!
Is it accurate.. hmmmm
But is it fun.. definitely!!

Bird saloon and more

3D printing with ABS isn't my thing. They say that this is a plastic that is easy to use but i have other experiences. Many cracks, bad layer adhesion and an overal poor print quality. This material is unusable for me but it's a waste to just throw it away. Because of that i just tried to make a few birdhouses.

Lithographs

Lithographs
Just some other exploring in the 3D printing area.
In this case it's lithographs. It's quite easy to make a 3D print out of a picture.
This is the result, an 3D image of a picture.

Now this seems like a small disaster, right?
Well actually it's not. See how the images emerge when you hold the print in front of some light.

Nice isn't it?

3D Catan

3D Catan
Started with this monster 3D print job.
A 3D version of the board game The Settlers of Catan. Each map piece takes about 4 to 5 hours to print. There are 37 map pieces to print, many player pieces, tokens and various other pieces.
I got these files from several upload locations at www.thingiverse.com

Dice tower

Dice tower
As a frequent boardgame player you know how annoying it is when your dice knocks down game pieces. To avoid this a dice tower can be used. One or more dice are thrown in at the top and they will roll out at the bottom. A nice moveable gate prevents them from traveling to far.

Gear heart

Heart made of gear
Since some time now i got a 3D printer and it opened a whole lot of possibilities
For example gears and my love for it. I printed these gears, picked them from the plate, snapped them together and it worked right away. Amazing!

Firepit

Sort of fire pit
While its hot at day the evenings are still a bit fresh. To get some warmth on the terrace i had a woodburner but using it always gave me a lot of smoke.
So the woodburner was seldom used. To overcome this i made a copper ring with a few small holes drilled in it and placed that in the burner. I topped the copper ring off with sand and made a propane connection at the bottom of the burner. The propane gas is slowly raising up through the sand and smokeless flames are dancing above the sand.

Cresting jig 2

Arrow cresting jig
Another arrow cresting jig. This time made from a cordless drill, wooden cutting board, aluminium bottle and a few discarded carbon arrows.
The whole thing is powered with an old accu charger because it draws 4 amps just to keep it turning.

Seats

Seats
With this modulair garden seat design my wife can play around and place it in different formations. But before she can do that in more then a few setups i have to make a few more pieces. So the design is approved and some more work for me.

Arrow cresting jig

Arrow cresting jig
For a friend i mine i made this arrow cresting jig. It's made from a set inline skate wheels, a few piece of aluminium and wood. The top left wheel is directly driven by a DC motor. A LM317T voltage regulator is used as speed control.

CNC mill

CNC mill
This is a Proxxon MF70 mill. It's a very small mill for model making, parts for watches and other small work. I made a CNC mill out of it by adding a stepper motor to each axis. The mill is placed on a sturdy wooden box wich contains the power source for the steppers, an Arduino Uno with GRBL running on it and a CNC shield with drivers for the stepper motors. The whole assemenbly is portable this way which makes it easier to put it at work where you want it to be. PCB mill with this CNC mill
I am planning to use it mainly for engraving and PCB making. This PCB is my first try of making one with a mill and i am glad it turned out right. Mission accomplished.

Spine tester

A friend of mine is a skilled bow maker. He makes wooden bows and all of his own arrows. However to make a matching set of arrows is a tedious task atleast. To speed things up he asked me to make a arorrow spine tester.
The arrow is placed at two points spaced 26 inch apart. Then a 2 ounce weight is plached on the arrow and the flexing is measured. On a scale you can see the flex in inches and read the corresponding arrow pounds.

Moon sketches

Now that i got a telescope i got to use it also. For doing that i look at all kind of interesting objects. The moon is one of the objects that is easily overlooked as a suitable subject.
I have no means to make a good photo through the telescope so i revert back to the art of sketching. This is the result of a few sessions.

Hand controller

For some other work in progress i needed a hand controller and i wanted to have one in style.
I made this controller with all scrap material except for the OLED 128x64 display. I used switches from an old VCR, which also provided a few aluminum pieces and a few resistors. A small PVC ring cut from a pipe. Two bottoms of soda cans for the display holder, some wood and epoxy resin.
I am particularly fond of the way it turned out. It's how i imagine how the tools look in the old SF stories.

Truss Dobson

Last year i started builing an 8" truss Dobson telescope. Over the months i learned a lot about construction, mirrors, optics and do's and do not's with telescopes. I had to rebuild a few parts several times due to wrong choices of wood, initial design or just plain wrongly build the thing. But in the end i am pleased with the result i got and the lessons learned.
Truss Dobson
The telescope has an 8" f4 mirror. This makes the assembled telescope about 1.2 meter tall which is a nice size to handle.
Closed box
The complete telescope can be folded into a box with these measurements.
295 x 255 x 175mm (L x W x H)
EQ Platform mounted
The box also contains the EQ platform that can be used as tracking platform to keep the object centered in your view while observing.
This will give you a much more relaxed viewing experience.
EQ Platform bottom
The EQ platform will be mounted on top of the box. The transmission i used is a DC motor, a small gearbox and rack and pigion. The rack is made out of a piece aluminium L-profile and I just used a vile to cut teeths in it.
Top ring
The wooden ring on top put tension on the trusses and makes everything really stiff. This ring also holds extra pieces of equipment such as self made helical focuser and a red dot finder.
Helical focuser
The diagonal mirror got dew protection included. However this mirror had to be detachable otherwise it didn't fit well in the box. For this I made a sliding shoe connection to detach the mirror.
Diagonal mirror
To get power up there without wires hanging loose i integrated the wiring into the woord of the top ring and trusses. Power will go throught the trusses and the connection between the truss and the ring. After that i use the metal vanes of the spider to get power to the diagonal mirror's dew protection.
Mirror box
At the bottom of the mirror box i made a 3.5mm jackplug connection into the base. With this I provide power to the main mirror fan and the dew protection of the diagonal mirror.
Controller I made a quick controler for the fan, dew protection and EQ platfrom to test things out. In the future this will be replaced for a much fancier piece.

Shinny's

Experiments with epoxy resin. All kind of small items such as leafs and flowers cast in epoxy resin. I made several shapes and sizes.
Some of the material changed reasonable in color due to the resin. Resin
