Hey guys I am sorry but My back is killing me today and i wont be able to make the meeting. But i was wonder if someone can bring up a question for me at the meeting

  • “is there anything that anyone Have anything that they use in the electronics area that is not set up due to the remodel that they need or want set up so that they can use it while things are in a bit of disarray.”

I hope that this helps to allow everyone to continue using the Electronics area while things are being organized.

  • you can feel free to add request to this POST

Thanks Doc Willey

We are also not going to be there tonight.

My broken ribs are keeping me at home. The timing really sucks, and it hurts a lot.

However, I am pleased to announce that the deluxe new reflow toaster controller arrived. It has an LCD, a buzzer, user friendly interface, etc, etc. Also, I am told our new stereo microscope is in. More supplies on the way, and we should have a PCB mill, etch capability, and an SMD workstation soon enough. Let me know if I’m overlooking anything.

Also I could still use help with stuff. This is for all of us, and suggestions just help improve my ability to make it better. Any ideas for quick and dirty fume extraction to the exhaust vent above purgatory? I don’t want to get caught up in cool new toys, neglect this aspect, and just end up using a box fan to blow all the solder and chemical fumes through the meeting area and into the kitchen…

I left a barrel section around for this very purpose in the metal room (it’s scrap otherwise)… It’s about 1/4 slice of a 55gal, but entirely flat on one side.

Quick + Dirty:-HVAC blower in purge metal area, obtain another if dead (easy)
-square discharge → round tube adapter (home de pot)
-tubing from discharge to vent (home de pot)
-tubing from inlet to adapter to couple pieces of 2" PVC with holes drilled down length, cap on far end. (think: fluorescent tubes with holes in them to allow airflow)

The only thing left to make it super functional would be to attach a bunch of white LED strips to the inside of the barrel so that it would double as a light source. If you’ve seen my mini-extraction fan with LEDs, similar concept but larger.

I’d offer to do the fab work but I’m doneski time wise for a bit… I’d rather not commit to something I don’t know when I’ll have time to finish. If I get time, I’ll try to mock something up.

Copy and paste from the previous time you asked.

I would suggest the following:

  1. Buy/build a converter to attach to the large 8-10" opening already in the window above purgatory. Not sure how large it is, or I’d make a more concrete suggestion, maybe we should check on Tuesday?
    Anyway, something like this:

  2. Shrink that down to 4", and attach this to the outlet:

    ($27)

  3. Run the duct down the wall to the soldering stations, and then across the back of the pallet racks.
    You’ll probably need 2-3 of these:

    ($5) per
    And an elbow:

    ($5)

  4. At each soldering station, install a T-section, one per station

    ($5) per

  5. Attach a 4" flexy hose:

    ($16)

You’ll also need a switch, box, and some electrical lines.
($10)

So for 3 stations, that comes to ~$90 or so. You can scale this up a bit if you’ve got the budget, to 6 or 8" which will increase the air flow a ton. If you do that, I’d just have a converter off the T-section. Unfortunately that will probably double the price, but it will also double the air flow. $4 pulls ~100 cfm, 6" ~220, 8" ~420
