THIS PAGE IS CURRENTLY UNDER CONSTRUCTION. WE ARE DOCUMENTING THE STEPS TO BUILD THE MODEL 1 PLATFORM. CHECK BACK FOR UPDATES OR SEND US YOUR EMAIL ADDRESS. IF YOU CAN'T WAIT TO GET STARTED CLICK ON THE ELEKTOR-LABS LINK AT THE TOP OF THE PAGE AND YOU WILL BE LINKED TO THE ELEKTOR-LABS WEBSITE WHERE WE HAVE POSTED MOST OF THE BUILD STEPS FOR THE MODEL 1 INCLUDING SOURCE CODE. ONCE ALL IMAGES HAVE BEEN CREATED AND POSTED WE WILL BE CREATING INDIVIDUAL PAGES FOR EACH STEP.
STEP 1 Step 1 Instructions Where To Find Parts Source Code
The two primary reasons we chose to use automobile brake rotors as our platform bases are they are easy to find at your local auto parts store or auto salvage yard and they are heavy.

Because we are using a vertical design to minimize space, the platform base needs to be sturdy to build upon and dampen vibrations.

For the SLTV Model 1 we chose a Pontiac brake rotor that fits well with the PVC base. You can use any brand of rotor you like, you will just need to make sure it will bolt to your PVC base.
Brake rotors can be found at:

  • Local auto parts stores
  • Online auto parts stores
  • Auto parts salvage yards or "junk yards"
  • Not Applicable

    Most brake rotors are made with iron which can cause them to rust. Be sure to coat the rotor with a lubricant like WD-40 or mineral oil to prevent it from rusting.

    Also note that because the brake rotor is very heavy, if you plan to place it on a surface that you don't want to scratch you can cover the bottom with a material like felt. Keep in mind that a material like felt will dampen vibrations. For the SLTV Model 1 we chose not to cover the bottom of the brake rotor with any material so that our sensors will pick up even the very smallest vibrations.

    Here you can see the PVC connector (in white) next to the brake rotor. You may need to drill new holes in the PVC connector to match the rotor's bolts. Here in the U.S. you can find the PVC connectors at Lowes and Home Depot hardware stores. You can also order online. Not Applicable
    STEP 4 Step 4 Instructions Where To Find Parts Source Code
    Once you have your holes drilled and the PVC connector placed on the rotor, you can use lug nuts to tighten the connector to the rotor. You may also want to install an LED light beneath the rotor to allow light to pass up through the acrylic tube. You can find lug nuts at most auto parts stores or order online. Not Applicable
    STEP 5 Step 5 Instructions Where To Find Parts Source Code
    You can now place a second PVC connector inside the first. Be sure to check to make sure they connect before purchasing.

    You have the option of making the second connector stationary or if you place a little oil along the surface between the two connectors this will allow the PVC platform to rotate which is useful when working on it.

    STEP 7 Step 7 Instructions Where To Find Parts Source Code
    Most acrylic tubes I found online come in pre-cut lengths that are too long for the model 1 & 2 platforms. To cut yours to the length you need you can place an oversized radiator clamp on the tube and use a marker to trace draw a cut line. I use two miter boxes to hold the tube in place while cutting it with a hack saw. Make small cuts along the line, stop and rotate the tube as you cut slowly. Go slowly as the hacksaw blade will cause the acrylic to melt and bind the blade if you cut too fast. There are many acrylic tube manufacturers online. Not Applicable
    STEP 8 Step 8 Instructions Where To Find Parts Source Code
    You will need to drill two holes at the base of the acrylic tube to allow you to mount the two guitar pickup volume controls. You should compare your drill bit with the width of the volume control so that it is not too tight or too loose. You can order an inexpensive guitar pickup with the volume and tone controls already put together at ebay or other online stores. Not Applicable
    STEP 9 Step 9 Instructions Where To Find Parts Source Code
    After the holes have been drilled, here you can see the Volume and Tone potentiometers mounted. Each has a washer and nut to tighten to the inside of the tube. See Step 8 Not Applicable
    STEP 10 Step 10 Instructions Where To Find Parts Source Code
    Here you can see the guitar pickup mounted on one of the clear acrylic shelves at the base of the tube. The tube is meant to keep the penedulum from being affected by any breeze or wind that would cause it to swing. The tube is not vacuum sealed though. Not Applicable

    This is a photo of the surveyor's pendulum, guitar pickup and volume and tone potentiometers on one of the acrylic shelves prior to installation. Not Applicable
    STEP 12 Step 12 Instructions Where To Find Parts Source Code
    The surveyor's pendulum is suspended by a string which is held in place by two pieces of "L-shaped" aluminum. This allows for an easy way to raise and lower the pendulum within a 1/16" above the guitar pickup. It also allows the pendulum to be moved directly above one of the six electric guitar pickup's magnets. Lowes, Home Depot, Ace and Tractor Supply Hardware Stores all have sections where you can purchase aluminum for fabricating. Not Applicable
