guys - I'm doing an automated blinds project and know where to get the motorized parts, etc but just realized most common websites are very expensive for the size I need (104x86). Have any of you just bought raw material and made your actual blinds? Or do you suggest any other website for lower costs - is aliexpress wortha try? I'm hoping to be under $200 for this size solar shades with 5% transparency in beige Thank you

Our PowerRise blinds started having problems going up and down. The motor started making loud squealing noises when moving. It seemed like the motor or gears were binding-up. I finally ended up taking the blinds apart, removing the motor, getting the motor specs and ordering a new motor from Ebay. The replacement motor fit perfectly. After re-assembling, it worked just like new...any much quieter. The motor spec is: Copal DC Gear Motor LA16G-324SH, 50:1 300RPM, 12V (4.8-14.8V). Also, years previously, the blinds weren't working, even after replacing the batteries. I found that the far end of the tube where the batteries are stacked was dirty and not making electrical contact. I put some steel wool on the end of w wooded dowel and stuck down the tube and after turning around and around many times and reinserting the batteries, things worked again...
