The New Old Project – multiplication

The song of the little Robot is silent for the moment as I consider my kitchen table of little fume scrubbers and contemplate, my NEXT number.

A multiplicity of scrubbers

A multiplicity of scrubbers

The Black Airwasher on the left has been working for me for a couple of weeks as We , the robot and I, create new additions to it’s family. The Blue and Whites are nearly ready to go out into the world. All spiffy in their livery and labels. They just need motors and containment tubs to be completed.  There is a also a box, a Large Box, full of scrap and failures to show for my learning experience along the way. I am pleased with both the appearance and function of these tiny industrial fume scrubbing machines.

( man I have got to get a better camera or learn how to better use this one)

As this is an R & D effort, completed Blue and Whites will be sent out on permanent loan to those that donate $250 to my effort, so that they can evaluate, under real world conditions,  and offer their wisdom for needed improvements.  And I can continue to buy coffee for me and filament & electricity for the robot.

Next is to design and create a better water management system and base to replace that food container. This thing is getting too big for the little printer’s build bed. I must section and then glue up this next addition that will make the Airwasher more user friendly. Adding 16 oz. of water every 4 hours is a necessary thing,  but an annoyance. A 2 liter water supply bottle or even two of them would make servicing only a daily chore. The hand made ones of 25 years ago had this feature and it was planned on in the consumer model, but this little printer was just too small for the needed build footprint…pg

And there it is ! I will need to rework the files for a better and easier to print addition to the Airwasher but it works!  😎  hurrah !

    If it ever stops raining/hailing/snowing in PG&E climate zone P and the roads are clear to your area, which appears to be in zone R, I’d like to come and pick up one of the blue and white units.

    Send me an email and we can work out the details.

    You are in luck as far as PG&E costs per kWh go this summer. Your baseline quantities are going up a tad, mine on the other hand are going down 10%. I haven’t been able to figure out the rational for the changes yet.

    Great post. I was checking continuously this blog
    and I am impressed! Very useful information particularly the last part 🙂 I
    care for such information much. I was seeking this certain information for
    a very long time. Thank you and good luck.

    p.g., have you considered keeping the reservoir small and adding a feeder bottle similar to a pet watering bowl?

    It’s not clear to me if the need for the water is because of evaporation or just needs changing out because it’s dirty.

    Here’s a link to what I’m referring to.

    @HR yep! the water bottle thing is the next step. In the earlier hand made Airwasher as well as the proposed consumer model had supply bottles, But the build bed was too small to include them. So the next thing is to design a 2 piece container cover that will have space for a 2 liter supply bottle as well as the scrubber section…pg.

    @kakatoa; today dawns clear and cold after last evenings snow here at 2000ft above Chico. Yesterday I spent rescuing MyLady’s car, that blew the power steering hose. Strange that it blew a factory joint on the low pressure return line. Steering that SUV with big tires and no assist was nearly impossible. At least that is fixed and she again has wheels.
    Anyway, the Air washers are coming together nicely, but an annoying buzz has prompted me to try redesign of the configuration of the scrub impeller, I think that the number count is wrong for the internal structure. Nice thing about the present manufacturing process, changes can be quickly made, executed and tested. When I originally designed it, I was much less comfortable with the needed design and build process. Now, it is no longer difficult to contemplate needed changes to make things work better. Then Email you directions on how to find me if you wish to visit me. or we can make shipping connections….pg
