Pair of linear actuators (found on eBay for 150)
Premium pine (Home Depot 50 bucks)
12v power supply (found in my electronics junk box)
Step 1: Design
Step 2: Gather all the parts
I went to Home Depot to find some wood, I ended up spending about 50 dollars for premium pine. All the cheap pine was warped and I figured a telescoping column should probably have straight edges.
Step 3: Cut and assemble the legs
I mounted the linear actuator to a small wood base, then built the inner column around it. Then the outer column around the inner.
I tested the first leg built to see if it could lift the table top. It did, so I built another one.
Step 4: Attach legs to table top
Step 5: Mount the switch and route the wires
I ran some extra wire so the desk could rise without snags.
Step 6: Finished
Takes about 60 seconds to change position, cost about 200 bucks.
If I spent maybe another 200 on the linear actuators I think they would be a bit faster and stronger. Also I would have rather had 18 or 20 inch stroke, but 16 was the most affordable.
The legs are definitely version 1.0, I know they don’t have to be this big, it was just really easy to make it this way.
I will eventually add something to program height positions. So I could just press the button once instead of having to hold it down. I have a Raspberry Pi laying around here somewhere.
