Boat Blower Wind Sim [Retired]

Retired Solution – See updated 120mm Fans solution.

My twin blower design uses either a 12 or 24v 100mm/4″ boat blower and Arduino Uno with a Monster Motor Shield while a honeycomb straightener ensures maximum wind is blown towards you.

Notes

Boat Blower

Either a SEAFLO 24v 4″ 235CFM In-Line Bilge Blower Fan which has a compact body and five blade fan or a SEAFLO 12v 4″ 270CFM In-Line Bilge Blower Fan that comes with a larger body and six blade fan will work.

Motor Shields

Finding a motor shield now the Sparkfun MotoMonster is retired is a bit more of a challenge. Thankfully there are plenty of clones out there such as this one from Aliexpress – Monster Moto Shield VNH2SP30. In order to keep it cool I added a couple of 15mm2 heatsinks and a 30mm fan of an appropriate voltage.

Hose

The fans are connected using a length of SMOOTH BORE DUST EXTRACTION/ SUCTION HOSE from eBay.
