Re: home improvement turns into science fair projects?

I just realize that yesterday for the first time in my life I used "duct tape" for its intended purpose . :lol: :lol: JR [edit The duct diffuser grilles have flow restrictor inserts giving me even more control over air flow. The 8" duct is spiral expandable that also contracts. If I restrict the inl...

Re: home improvement turns into science fair projects?

My basement is at 84% RH right now and it hasn't rained in 10+ days. I need a plan. I have been running dehumidifiers 24x7 for years... My Frigidaire is better than my Aeonaire but I am on my second Aeonaire. [edit] The second Aeonaire was a "free" replacement when the dehumidifier got stupid... I ...

Re: Entropy

Going back to the water-contaminated fuel... I think a can of Berryman's carb cleaner works at making water-contaminated fuel burnable. Same principle as Heet which Bill mentioned. I am still seeing an operating temperature issue... last weeks roll was still sluggish (missing?) even while up on the...

Re: Entropy

More entropy Barry blew down my outdoor temperature sensor resulting in an 8' drop to a concrete floor. I took it apart and didn't see a problem but still no love from the indoor receiver, even after I touched up a few solder connections. I finally had to use the "Bangalore reset" (Please unplug you...

Re: Entropy

New rain ditch drama Hurricane (cough) tropical storm Barry came and went… I appreciate the concern down in NOLA because of high water levels in the MS river, and wet ground, but I hadn’t seen an inch of rain total in Hickory the last two weeks. After three full days of flash flood watch we got a to...

Re: home improvement turns into science fair projects?

I finished my chores and moved the main blower into the back bedroom where there is already a dehumidifier and air filter making noise. 15' of 8" duct and air inlet cover reach my main room... the noise is very manageable as is. I need to see how the temps and humidity play out... I hope to cool the...

Re: home improvement turns into science fair projects?

don't you have a variac hanging around? As they are usually around the 50-75W power consumption you must have a transformer somewhere in the shed that would drop down enough to get it quiet. IIRC you can go down about 50% on voltage before it goes non linear for flow. I actually do (i thought I men...

Re: New: A Direct-Coupled Input-Capacitorless Active Mic Preamp

I often go back through old data books and application notes and when I do always see something I've missed or see an old idea that may be applicable in a completely different area. Today was one of those days. While quick-reading Burr Brown's 1987 "The Handbook of Linear IC Applications" I found a...

Re: home improvement turns into science fair projects?

I just ordered some experimental run caps for my whisper/blower. I still have no idea of the correct size or if they will even work at all, but that is typical for my life experience. :lol: As long as I was buying odd parts I ordered some 47uH inductors to swap out in my Franken-lamp version III... ...
