Scissor LED Desk Lamp
This is a desk lamp that can be regulate to any position covering completely a table and you can put it real close when soldering and harder when reading, another advantage of the scissor mechanism is that is very compact when close. The LED's make this lamp head very slim so it isn't in the way as much as a bulb light.
I can't recommend enough to see the video before

Prepare the Pop Sticks
Dril 3 holes in 15 pop sticks i recommend making a little jig with nail and some wood the holes one have to be in the center and the other tow center side ways and the same distance from the side edge to de center than de distance from the length edge like in the picture, now two of the pop sticks need to be cut in half being left with two holes
Make the Scissor
Start assembling 10 sticks in X pattern with the small rivet so you have 5 X when hammering the rivet do it slow and check if the are secure and can move freely now unify all X's at both edges add the half stick in the bottom and at the top the full stick follow by rivet in the middle of the long stick and trow the edge of the half stick only in the left side leaving the other side unattached like the picture
The Wire
Drill two of the smallest hole you can close to the rivet in the bottom of the sticks and with a coper wire tie the wire to the sticks making sure that the cable stays in place, a tip when drilling the holes is to place some kind of instant glue in both sides to prevent splits in the wood and another tip is to secure the copper cable with instant glue
Place the LEDs
Place as many LED in two aluminum plates of 200*35mm the amount i use is more than enough and solder positive with positive and negative to negative in a zig zag like the picture and solder the LED dimer red is positive and black negative
Assemble the Two LED Plates
Cut two 15*35mm plates of aluminum drill at edges and bend in the middle at a 30 degrees more or less, the drill the plates that we make before and place the brackets with rivets, File two angles so they don't stick out the the are place in the meddle space with the with of the stick, and mounted like the 30 degrees bracket
The Head With the Arm
Place a screw through the angles and the stick tie the nut until it doesn't fall but you can move it
Height Regulator
Get the last stick and unify the two holes like the picture, copy this int o sheet of metal from a can then glue the two pieces follow by using a file to smooth the edges
The Support
Copy the sketch into a pice of aluminum follow by drilling and taping the holes, file and sand all the edges so its not sharp attach this to the hinge with rivets and assemble everything like the video in the minute 13:48
Electronics
This is very easy just solder from the power brick to the arm cable positive with positive and negative with negative and the same with the arm cable and the led dimer just one more thing cover every thing with electrical tape
Conclusion
This turn out to be a great project and very useful Thanks for reading and i will answer any comment
