We are installing an intercom system and the front door unit is meant to be mounted in a recess in the wall. But the problem is that that wall is not really suitable for making such a hole.
I cut some strips of flat stock and fashioned a box. It has a couple of tabs to bolt into the wall and another ones threaded to hold the device. This is going to be painted later but I love that blue shading.
I’ve been working on and off on this for the last couple of weeks. The space we’ll have on the comms rack to handle the wiring isn’t that great and I saw on a couple of places patchbays that are articulated.
I thought on adding a twist to that and mounting everything on rails. This way I can slide it from behind the rack and then unfold it, gaining access to both sides.
We bought some pre-drilled (but not taped, ugh.) angle with the holes spaced in standard units, that was welded into a fixed frame with a couple of hinges.
This will hang from a small cart with iron wheels that rides on a couple of rails fixed to the walls.
With the outer frame already built I continued with the doors. During the last couple of days I made the frames, aligned the hinges and had them welded. I also started to cut the expanded metal for the body and made a couple of simple handles.
Today while working on the rack closet the welder died on me for no apparent reason. But, after power off it made a couple of noises and the fan ran for a moment.
For being a Chinese machine it actually looks quite good and neat on the inside. The boards have conformal coating and just a tad of flux residue on some pads. The only thing out of place was a blob of solder on a header instead of a jumper.
I made a couple of measurements, the high voltage section was fine but the control supply was totally dead, except for a brief moment when turning off the main switch. Traced back from that board until finding a small block with a forward converter (kinda odd, I expected a flyback). The only component with bad readings was the recovery diode. I swapped in an UF4007 and at the next flick it was alive again.
Of all the things that could go wrong with a welder on novice hands this was not expected.
Sunday was a very nice day among friends and partners of our neighborhood.
Instead of finishing a draft post about that I’m sad. I spent most of this Monday listening to our representatives going around circles instead of voting, while some of my friends were treated like terrorists, being searched by masked officers at gun point, others punched and kicked.
I listened to the live stream for about ten hours before the sleep took over. Most of the ‘normal’ people I met yesterday chose to ignore this and watch crap tv. Meanwhile in Japan they have entertainment shows like Supreme Skills where they pit engineers and craftsmen to see which one is able to complete very demanding projects. Some of them are very light on the details but nonetheless the content is still better than other productions and showcases a complete different scale of values.
On weekends most of us choose to numb our minds with meaningless stuff. Others enlighten themselves.
Near the end, when we were almost finishing packing up a police car appeared. They said someone made a complaint about noises and that we should turn it down.
By then, after a very loud party on the street, there was just a small powered speaker, so we just unplugged it. They walked away, tail between their legs, but before that took all my personal data just in case.
30 Años de FM Futura. La Plata, Buenos Aires, Argentina
Las night I had the privilege of meeting Kubero Díaz, a legend of argentinian music.
It’s refreshing seeing someone so great being so natural and friendly, without airs of big star. He talked a lot about his adventures with Jorge Pinchevsky in Europe and played many songs for us with the same energy he had on his youth.
I bought his last work, a magnificent cd with a beautiful crafted artwork, and he had the generosity of signing it.
We were wanting to do this for quite a while. After installing led flood lamps over the transoms the whole corner transformed. I really like how the mixture of cold and warm lights inside portrait a scene through the frosted glass.
