  • In an effort to assessing what I have, Instarted going through the boxes of stuff at and found some interesting things to bring to MakerCave to work on: ShiftBrite LED Modules, various motors, an Apple TV and 5-port hub.  

    Interesting Items Discovered at Home for MakerCave

     
  • Every shop worth its weight should have a copy of the McMaster-Carr catalog.

  • I started assembling my newly-arrived Kickstarter-backed Dobot Robotic Arm.

  • I installed a guide on the Shapeoko to better align the work piece.

  • I engraved the Portland skyline art on the Portland Media Community TV Shroud.

  • To make more desktop space at the Electronics Workspace, I made a cantilevered laptop tray.

  • With the Portland skyline artwork routed out, I laid the first layer of wood filler.

  • I hooked up the Apple TV to one of the GT5000 NEC Projectors.

  • McKenzie and I picked up the Oneida Air Systems Deluxe Dust Deputy Kit from Woodcraft, and I assembled it. It works great.

  • From home, I brought the powered breadboard for the Electronics Workspace.

  • While figuring out what to do, I started updating the various computers here.

  • Last night, Jill and I won the fourth grade class auction project, and it is on temporary exhibit at MakerCave.

    On temporary exhibit at MakerCave…

  • I drilled a 2″ hole in the table top of the Electronics Workspace and slipped in the Tankstation into place. Now I can charge my electronic devices to my heart’s content. 
  • I made another electronics tool caddy for my larger tools that wouldn’t fit in the first tool caddy.

  • I managed some additional improvements on my Printrbot Simple Metal base, like this swing arm for the Raspberry Pi.

  •  I also added a small storage box.

  • Too often, when doing an annual event, you often just throw things immedaitely back into storage until the next year and forgot get about any problems or issues. Here is my attempt not to do that. The attachment apparatus for the light string support poles to the hotel tables is not very stable. We have been taping or zip-tying the mounts to the table legs. For next year, I would like to make a clamping mechanism, which would be more stable.

  •  Last night, I sketched up a design for the water flow pressure sensor and then printed it out on the Printrbot Simple Metal. Unfortunately, I didn’t make the inside of the mount high enough and had to file away material in order to accommodate the sensor. For the future, I modified the SketchUp model by increasing the height by 2 millimeter from 32mm to 34mm.

    Water Flow Pressure Sensor Mount Installation

  •  Originally, I had planned to bolt the mount to the floor of the electronics cavity next to the laser power supply, but the mount was pretty and protected and could be left freestanding. Perhaps I will velcro it in place, but it works as is.

  • After work, I stopped in to look for my misplaced Leatherman. I hate when I do that, and no, I didn’t find it.
  • While there, I decided to hook up the Tekpower Digital Multimeter DT9602R to the Ubuntu Linux Laptop at the Electronics Workspace. Sorry, no photos. I forgot to take some. 
  • Luckily the laptop is old enough to have a serial port, so no need for a Serial-to-USB adapter. However, the enclosure around the computer end of the cable obstructed the end from being able to be plugged in. Luckily, it can be easily removed, and the cable could now be plugged in. Another design opportunity for the 3D printer.
  • I was also having difficulty connecting to the multimeter with the QtDMM software. However, I fixed that issue by running the program with the sudo command.
  • I need to research how to open the serial port to all users and QtDMM doesn’t need to ran under sudo.

  • While cleaning MakerCave, I made an assessment of the scrap materials available and made this wire spool holder for the electronics workspace.

  • I grabbed some measurements of the water flow sensor and sketched out a mount.

  • I installed the tee on the water cooling inlet for the K40 Laser Engraver and Cutter. I turned on the water pump to check for leaks and heard the activation of the switch in the sensor, a good sign.

  • In preparation of updating the firmware on my Deltaprintr, I installed Arduino IDE 1.0.6 and the other necessary libraries on the electronics workspace laptop. I was able to successfully able to compile the stock firmware.

  • While at it, I also installed QtDMM on the electronics workspace laptop, which allows me to read and record the readings from my TekPower DT9602R Multimeter.

  • I managed to clean off one work surface.

  • I managed to gather several dust piles around the shop.

  • Placed the water flow sensor inside the K40 Laser Engraver and Cutter

  • Ran the tubing from the water flow sensor out the back through a pre-existing hole. The tee fitting will be installed in the inlet tube, and water will then flow to the water flow sensor.

  • Made a wiring for the water flow sensor to the laser controller. I forgot my crimpers at work, so I still need crimp the female connectors to the wiring.

  • Repurposed a Linux laptop for the electronics workspace to access the Internet for reference and access the USB microscope to examine circuit boards

  • Completed my electronics workspace tool caddy

  • Brought from home the large Panavise, helping hands and USB microscope for the electronics workspace

  • Using scrap around the shop, I began making a tool holder for the electronics workspace.

  • Finished the electronics workspace tool caddy…now wait for adhesive to dry
