We live in a 150 year old farm house with the original windows. Despite insulation and new siding, it is like living in a sieve, in the winter time . To combat this problem we install plastic over the windows to try and stop the drafts. This has to be installed on the inside or the winter winds will just tear it up. I built this contraption to open and close out blinds in the winter time.
Step 1: The Power Source
I started with a Black and Decker $10 drill/screwdriver. I tried several different motors but none of them had enough torque to turn the shaft to open the blind.
Step 2: The Rest of the Parts
These are the parts I will use to modify the drill into a powered blind opener.
1. A 6 volt power adapter (wall wart)
2. LED assembly
3. A small project box
4. Power Jack
5. Power Plug
Step 3: Disassembly
The first step was to remove the handle from the motor. Be careful doing this as you dont want to cut the wires yet. Cut as close to the body as possible.
Step 4: The Switch
After removing the handle, seperate it, and remove the switch. We will extend the wires and use this to control the opener. All this switch really does is reverse the polarity of the DC current. Unsolder the motor and the battery connector from the pcb.
Step 5: Preparing the Motor
This is the power end of the driver. The motor is just visible. We need to make the cut area as flat as possible to secure it to the wooden block used to mount it.
Step 6: Back-up Power
The next step is to prepare the batteries for back-up power. I retained the batteries because living in the country, we do do lose power once in a while. This will allow us to still open the blinds if the power fails.
*** A word of caution: If you must solder batteries you have to be very careful. To much heat can cause batteries to explode.***
Step 7: Building the Switch Box
First fit the switch in the box then cut a hole in the lid to fit the switch.
