  • CAN BOOST THE POWER OF MY BLACKTOOTH LASER?

    Upgrade your mirrors to SI coated mirrors, using a HQ ZnSe lens and even pushing up to a beam expander will all boost power. The ideal order of experimenation for lowest cost would be changing out for a higher quality lens labeled HQ ZnSE lens. Next would be SI mirrors, which will absorb less heat and reflect better, the last would be to use a beam expander which expands the beam, reducing the heat signature on the mirrors and makes a tighter focal width.

  • HOW DO ADDRESS THE DANGER OF THESE CNC MACHINES

    These machines are inherently dangerous. Before the machine moves, the machine should be clear of any person by a dimension of at the distance of a persons reach plus a few more feet. This is the policies we institute in our shop and what is recommend to all of our customers. Treat these machines as you would treat any major power tool in the shop.

    With that said, you can certainly add some protective parts, but still keep folks away even with those installed. I would use the gantry side to do all of the mounting of the protective parts. Consider using sheet metal that you can bend and make a simple installation right on the gantry side.

  • WHAT THICKNESS OF MATERIAL CAN THE BLACKTOOTH LASER CUT?

    A standard 40W CO2 laser will cut up to 1/4" thick of material, be it wood, acrylic, card stock, leather, fabric, foam, cork, etc. (Decent speed and final cut are heavily dependent on a strong air assist upgrade)

    Metals cannot be cut due to the power level and wavelength of the CO2 laser. But it can be marked with special solutions like Cermark or Thermark.

  • WHAT ARE THE HEALTH RISKS OF LIVING NEAR A CELL PHONE TOWER?

    There is very little radiofrequency (RF) energy exposure to people inside a building from a cellular base station located on its roof. There are several reasons for this. First, the transmitters operate at low power levels. Second, the antennas are normally mounted near the edges of the roof and are aimed away from the building. Third, most cellular transmitters use "high gain" or panel antennas. Such antennas transmit most of their energy in a narrow beam (in the vertical direction) from their front surfaces, away from the building. They radiate very little energy downwards towards the roof or backwards from their rear surfaces. Finally, building materials absorb a significant fraction of the RF energy passing through them. As a result, the RF signal levels at any location inside the building are invariably low and far below safety limits. The situation might be different in some locations on the roof itself. RF signal levels close to (within a few feet) and directly in front of cellular base station antennas can easily exceed safety limits. Some precautions are needed to prevent people from walking directly in front of the antennas while they are transmitting. This applies also to paging and other systems that use rooftop antennas, some of which transmit at higher power levels than many cellular base stations. Kenneth R. Foster, Ph.D.
