28BYJ-48 Based Laser Gimbal

 

In this video you see the start of the assembly of the laser gimbal based upon the thingiverse design (www.thingiverse.com/thing:794786) with the addition of an in house designed base (on which to mount the gimbal with the stepper control boards) which can be found on TinkerCAD (www.tinkercad.com/things/kkIE3qFwVO1-28byj-48-gimbal-base).  Watch for more on this too as we move forward with the build and program with the Arduino too!

Note: We taped the bottom of the base with 0.25inch x 20TPI threads to allow the gimbal to be mounted on a standard tripod.

 

 

28BYJ-48 Based Camera Slider Part 1

 

Here is the first part of the build of the 28BYJ-48 stepper based camera slider, the base mounts came from Thnigiverse and uses two #6-32TPI rods and one #8-32TPI drive screw.  In the next video we will add the rear spacer and the slide table so stay tuned for more!

Note: The 28BYJ-48 stepper motor mount can be found on Thingiverse at www.thingiverse.com/thing:423357.  Worth mentioning is there are several mounts, so if you looking to playing around with the 28BYJ-48 stepper motors then this build would be worth bookmarking.

 

Web Cam Bracket for XYZprinting Da Vinci 2.0 Duo 3D Printer

Looking for a way to add a web camera to the labs XYZprinting Da Vinci 2.0 Duo 3D Printer without voiding the warranty, we came up with this nifty idea.  The basic concept is to clip it to the stamp-out for LCD screen (inside the case) and the width is about 0.75 inches.  Now the angle is around 30deg of stamp-out and one of the things we need to do is push the camera back a bit into the door opening (note: the door will still close because of the offset) as there was a focus issue being too close.  The bracket can be downloaded and printed from TinkerCAD at www.tinkercad.com/things/iZqDlaLIWBT-da-vinci-20-duo-web-camera-bracket.  SInce the camera which we use is rather light (in weight), we only used the standard light weight build settings.

3D Printed 28BYJ-48 Mounts

Working on a couple Arduino projects in the lab so  we decided to print a couple 28BYJ-48 Mounts on the XYZprinting Da Vinci 2.0 Duo 3D Printer.  So you can see how they are printed, we set temp up on the bed 90 deg to each as they are a matching pair so you see the side as well a the front being printed in this time-lapse video.  They where printed at a medium fill and think shell since they will have to take some torque.

3D Printed Gimbal Mount Base

Designed and printed a gimbal mount base for a 28BYJ-48 gimbal project which we found on Thingiverse (www.thingiverse.com/thing:794786) and the STL file for the base can be found on TinkerCad (www.tinkercad.com/things/kkIE3qFwVO1-28byj-48-gimbal-base).  We used the XYZprinting Da Vinci 2.0 Duo 3D Printer and medium fill with thick shell for the print settings.  If you notice the center is built up a bit with 1/4 Inch hole which will be taped with 20TPI thread to mount on a tripod.  While the Thingiverse design shows a laser.  We will also design a mount for a small web camera turning the project into a pan and tilt which can be placed on a tripod.  We see a lot of uses for this design from security systems to pan and tilt photography applications.

Arduino PrefBoard stand 3D Printed

This is a 3D printed Ardrino Perfboard stand printed on an XYZprinting Da Vinci 2.0 Duo 3D Printer

 

Since in the lab we have started to play with the Arduino for a couple projects (seems 3D printing and microcontrollers), printing a stand for the Arduino and a half perfboard was a good idea. So off to Thingiverse we went and downloaded one and to XYZprinting Da Vinci 2.0 Duo 3D Printer we sent it for printing.  We used all the standard settings for the print including rafting which seems a must since the 2.1.4 firmware release where the max bed temp seems to have been lowered to only 70 Deg.  Look for more on this coming soon.

Raspberry Pi Stacker Printed on XYZprinting Da Vinci 2.0 Duo 3D Printer

One of the things we’ve been working on lately’s playing around with the raspberry pie an like any good raspberry pi enthusiast we’ve been working on building a supercomputer and while it  won’t make the world’s 500 list of supercomputers it’s a fun project with a lot of learning however one of the things we identified we needed early on was a way to stack the Pi’s together to achieve this we went on to Thingiverse and downloaded an STL image of the stackable case from here we use the Da Vinci 3-D printer to print out the version above you’ll see a time lapse video of the printing.

SainSmart 2 Channel 5v 3D Printed Really Board Mount

3D Printed SainSmart 2 Channel 5volt Relay board mount printed on a XYZprinting Da Vinci 2.0 Duo 3D Printer

Here is our newest design, a mounting bracket for a SainSmart 2 channel 5volt relay board mount which can be used with either the Arduino or Raspberry Pi (along with many others).  These are very economical relay units and we picked up a half a dozen to play with and then we discovered, we needed a way to mount them and the

" target="_blank" rel="noopener noreferrer">XYZprinting Da Vinci 2.0 Duo 3D Printer came to the rescue as we drew this up in TinkerCad design and printed it out. Notice there are four 0.5 inch stand offs to mount the board and four tabs with 0.125 inch holes for mounting.  One of the big uses for this is a garage door actuator, as we have two doors so interfacing with a Raspberry Pi to build a web based door opener seemed like a good project.  As the idea with the tabs is to use drywall anchors and mount the relays and Pi close to the existing switch using a short run of wire to connect the two together.  The power for this will come from the near by garage light switch as a small power supply will tucked away in the wall (use care and engage a professional if your not experienced with dealing, with house level currents).

Inverted 3D Printed Video Camera Adapter

3D Printed Camera Bracket Printed on XYZprinting Da Vinci 2.0 Duo 3D Printer

So here is my latest design and it can be found tilted as Camera Inverting Bracket on TinkerCad.com and the idea is to mount a video camera to a photo copy stand and maintain the correct perspective as with a still photograph you can just flip it around, while video is not so forgiving.  Also while hard to see there is small notch in the side for the mic of the camera I designed it for.

3D Printing Tip: notice the two holes, the closest one was made to be 0.26 inches to allow 0.25 inch bolt (which will attach the camera) so the tip is to over size it a bit as the plastic (ABS) will contract a small bit and since the “print” is somewhat hollow you want to avoid having to drill out the hole as this will weaken the shell.  The second tip is the other hole will tapped with 0.25 inch threads, so I will print this with thinker shells and at 0.22 inches to allow enough material to tap.

Now my camera is rather small and this is the reason for simply tapping the hole rather than using a hex nut, also many tripod length studs are too short to pass though a bracket and into a nut as the tripod hole of many cameras are just to sallow.  So just a word of cation as I would not use this for one of my SLR cameras as they are simply to heavy.  Once I get a print on the
