## Project Box. ### For Variable Speed DC Fan Control Unit. ---------------------------------------- [Bobblejot Website](http://bobblejot.com) [Bobblejot GitHub](https://github.com/Bobblejot/) [Bobblejot Twitter](https://twitter.com/bobblejot) [Bobblejot Patreon](https://www.patreon.com/join/bobblejot) ---------------------------------------- ** Details: ** I designed a small box for an installation on site to control the speed of a DC fan using a variable speed DC power supply. The unit was only 12 volts direct current and 0.9 amps, and it needed a basic tension adjuster. I replaced the original expensive power supply and tension unit with a £10 DC supply and a £10 PWM fan controller, along with a £6 display. It was a cost-effective solution. ---------------------------------------- ** Materials: ** The items I purchased from Amazon include: <a href="https://www.amazon.co.uk/KeerSen-Switching-Regulated-Transformer-Protection/dp/B01DDIHKQM/ref=as_li_ss_il?ie=UTF8&qid=1512047291&sr=8-17&keywords=12v+dc+power+supply&linkCode=li2&tag=lmcse-21&linkId=d8b6d0453eb17525f48ffebef8be1896" target="_blank"><img border="0" src="//ws-eu.amazon-adsystem.com/widgets/q?_encoding=UTF8&ASIN=B01DDIHKQM&Format=_SL160_&ID=AsinImage&MarketPlace=GB&ServiceVersion=20070822&WS=1&tag=lmcse-21" ></a><img src="https://ir-uk.amazon-adsystem.com/e/ir?t=lmcse-21&l=li2&o=2&a=B01DDIHKQM" width="1" height="1" border="0" alt="" style="border:none !important; margin:0px !important;" /> <a href="https://www.amazon.co.uk/gp/product/B00HECIEWI/ref=as_li_ss_il?ie=UTF8&psc=1&linkCode=li2&tag=lmcse-21&linkId=e26588b84a72c9e8e17d1c1ad9ee45c0" target="_blank"><img border="0" src="//ws-eu.amazon-adsystem.com/widgets/q?_encoding=UTF8&ASIN=B00HECIEWI&Format=_SL160_&ID=AsinImage&MarketPlace=GB&ServiceVersion=20070822&WS=1&tag=lmcse-21" ></a><img src="https://ir-uk.amazon-adsystem.com/e/ir?t=lmcse-21&l=li2&o=2&a=B00HECIEWI" width="1" height="1" border="0" alt="" style="border:none !important; margin:0px !important;" /> <a href="https://www.amazon.co.uk/Controller-Adjustable-Governor-Regulator-Protection/dp/B015WBS7WO/ref=as_li_ss_il?_encoding=UTF8&psc=1&refRID=3WZC519D32QNF9EV33AY&linkCode=li2&tag=lmcse-21&linkId=971d723be330ecdf068c874c014eb04e" target="_blank"><img border="0" src="//ws-eu.amazon-adsystem.com/widgets/q?_encoding=UTF8&ASIN=B015WBS7WO&Format=_SL160_&ID=AsinImage&MarketPlace=GB&ServiceVersion=20070822&WS=1&tag=lmcse-21" ></a><img src="https://ir-uk.amazon-adsystem.com/e/ir?t=lmcse-21&l=li2&o=2&a=B015WBS7WO" width="1" height="1" border="0" alt="" style="border:none !important; margin:0px !important;" />
