Electronic Integration

Brash partnered with NonZero to develop their first product to the eSports market. What came to Brash as an idea quickly grew in scope to a complete turnkey solution. Brash’s team designed and developed every aspect of this product– from its shape and feel to the electromechanical integration; from prototype production to manufacturing.

Radiant Heating

Brash developed a revolutionary heating technology to help quickly heat the warming pad to a desired temperature within a few minutes. The team focused on finding the correct temperature to give off enough heat without burning the skin. The resulting product delivered a warm and attractive product that was sought after by gamers and those just looking to warm up.
