Building the Infrabed 2.0 - Part II.
Notice that this part is mostly dedicated to the wiring process, which was masterfully conducted by Scottie and Fabric.
---------------------------------------------------
The top panel can rotate relative to the rest of the structure, thus user can easily go in and out the device. The infrabed is like a giant waffle maker. Here is a detail of the rotating device, a hole is drilled through the top frame and the post:
Against the end of the hole, inside the top frame, is installed a claw nut:
A threaded rod screwed on a knob screw goes through the holes, holding the top panel on the posts and allowing rotation:
Now we install stoppers to hold the top panel in the down (horizontal) position. This is another improvement compared to the Infrabed 1.0. In the previous version the stoppers were too weak (6X4) and the stress exerted by the gas springs tore them away from the top frame. Now the stopper are (11X4)
The control box is very simple, it's basically 5 pieces of plywood glue and nailed (brad nails) together, here is the final result:
Most of the building being finalized, it's now time to focus on the wiring. First, we cut the LED strips in 60cm sections:
Then, we solder pairs of tiny phone wires to each LED section. There are 90 sections: 44 on the bottom frame and 36 on the top frame. That's another improvement compared to the Infrabed 1.0 which 'only' had 72 sections of LED.
When soldering is complete, the LED strips are laid and glued in their grooves, and their wire pairs are passed through the groove holes (see green arrow in the picture below). Then we flip the plywood and start making the main line (red arrow) that will feed each pair of wires :
At this point we solder each pair of phone wires to the main line. The pressure to do a good job was huge because you can see our furry supervisor on the floor, watching over each step of the process. Here is the result:
We then start installing the two power bricks. One will power the top frame while the other one will power the bottom frame. Notice that the output wires have been stripped and equipped with quick connectors (see turquoise arrow). This quick connectors will eventually be connected to the main lines that were previously described:
Under the boards on which the power bricks stand, is screwed a connection box where we located the quick connectors. From Fabric's face, wiring seems to be a highly enjoyable activity :)
Now we are ready to install the plywood sheet onto the frame:
Now we follow the same procedure for the top panel. In the picture below, you can see the main line (turquoise arrow). The line is wrapped in black electrical tape to prevent any short. You can also see the box with the timer (red arrow) and the on/off light (green arrow):
At this point we can fasten the LED panel and the plexiglass sheet onto the top frame:
Next step is to attach the control box to the top frame:
We can finally assemble the whole thing, plug it and test it, making sure all each LED lights up. For this test, we use a infrared monocular:
It works! :
Here is the final result, the Infrabed 2.0 now lays peacefully in its den
