Using correct terminology and spelling counts significantly toward your reader's perception of your technical expertise. It's not unreasonable to associate a poor understanding of the subject matter if the information is conveyed in pidgin.
do they sell adjustable fan speed controllers at lowes or home depot?
The ones I see on Lowes', Home Depot's & Builder's Square's websites are all 3 or 4 speed controllers, not continuously variable. Menards' website is lame and doesn't list all products. Check your local lighting supply stores. If they carry ceiling fans, they will likely have the continuously variable speed controls.
This is the sort I get locally ($AUD30), mounted on an extension lead.
