First working prototype of the Portuaria Lamp! 💪
Although it is a desk lamp, I will be using it as a bedside lamp to test the mechanical stability against being hit in the dark.
There are still several things to improve:
- The cotton-covered cable gets very linty and stains very easily.
- The ceramic screen also needs modifications. I can see the screws 😱.
- Making the vertical axis of the lamp perfectly square is hard 🤯.

The time has come to assemble the base. The idea is to have a printed circuit board with the voltage booster, resistors, and connectors for the LED and the switch, and at the same time to act as a cover for all the wiring.
Sending the printed circuit board to be manufactured in China as usual implies a delay of at least a month in the mail, so I decided to improvise something with a blank board. It didn't turn out so bad 😁.

The holes are for the switch, the cable, and the vertical rod. The one for the rod ended a bit loose; drilling it with a 10 mm bit to fit a 10 mm rod was too optimistic. Next time, I'm going to use a 3/8" drill bit and sand the end of the rod until it fits just right.

Carving the lamp base with a router to mount the USB voltage booster, resistors and switch.
The router is not quite tamed yet, doing this I learned that turning it off and on again in the middle of a slot is not a good idea 😬. I finished it with a chisel, slow but more predictable 🤷♂️.

After a lot of experimenting with various models of the height-adjusting disc that holds the cable near the base, I decided that it would be better to make the height fixed instead of adjustable 🤷♂️
The main problem is that it is very difficult to make the adjustment fluid enough to adjust the height without the lamp jumping, which does not look good as a user experience.

Assembling the head of the lamp. Despite the chamfered slot, it turned out pretty well. The yellow thing at the tip of the cotton sheath is a heat-shrink with glue, which is then inserted under pressure into the slot. It's the first thing that occurred to me to fix the sheath to the rod so that it can withstand the tension. Perhaps in the next iteration I will replace that with a screw, although the limited space is a challenge.

First attempt to mount the lamp head on the rod 🤔. What seemed easy in the drawing turned out not to be so easy when transferring it to materials.
The difficult thing was making the 3 mm slot in the 10 mm rod, and getting it to align with tolerances of less than 1 mm.
Next time I'm going to try with a router and templates, we'll see how it goes with that.

The screws pass between the heatsink fins and will attach both the lampshade and heatsink to the wooden rod.
-
Recycling ceramics to build a lampshade. I found that these mini bowls I made to test ceramic glazes roughly fit what I need for the lampshade of the prototype, so I drilled one to accommodate the LED and two screws.
-
Then I cut a circle with the hand router using the guide as a compass, and sanded it with the orbital sander and sanding sponge.
-
I wanted the base of the lamp to be a 16 x 2 cm disc, but I only had 7 x 2 cm boards around here, so I ended up glueing a few cuts.

💡 New project! An USB powered LED desk lamp made of wood, ceramic, and aluminum. It will be called "Portuaria", which in Spanish means "related to the port", because its shape reminds me of the cranes and sailboats at the port.
