This guide is adapted from the Let's split guide.

It is tailored between the Scrooges like me and all the europeans that couldn't find some TRRS jacks.

Cost Breakdown

Cost	Part
$8	PCB
€ 12-30	Pro Micros
€3-8	Diodes
€14-80	Switches
€14-180	Keycaps

This is a very cheap build, mine was about 30 € given that I already had the keycaps.

Mount the Diodes

Diodes allow current to flow in one direction only. Mount the diodes with the black (negative, cathode) line facing the thicker line.

Double check your work.

Tip: Lightly tack each diode in from the top. This will keep them snug against the surface once we flip it over and do the real soldering from the bottom. You only need a tiny amount of solder here and you should still be able to see through the hole.

Connect Jumpers

This part is not really needed, but you may want to do it in case you will mount the TRRS jacks in the future.

On the underside of the PCB, right below the TRRS jack, you'll see two sets of 3 pads labelled VCC and GND. Jumper them like this:

VCC [x]     [ ] VCC
    [x]     [x]
GND [ ]     [x] GND

Do both PCBs the same.

Mount Header Pins

You should have received header pins with your Pro Micro. Insert the short side into the bottom of PCB and solder them in.

Tip: To keep them aligned you can slip the Pro Micro over the pins but do not solder the Pro Micro at this time.

Tack the pins on the end and inspect. If the pins are not quite aligned with the board, heat one side with your iron and press it in. It should make a satisfactory "click".

Solder the rest of the pins (it won't take much solder here).

The long part of the pins should be protruding from the bottom. We'll trim these later after soldering the Pro Micro, but you can leave them be for now.

Mount the Pro Micro

Pay special attention on this step. There are several things that need to be done in the right order and orientation.

Tip: Flash your Pro Micro now before you mount it. You can test it by using a multimeter to measure the voltage between VCC and RAW. It should be around 5V. If it's bad it'll be a lot less headache than desoldering.

Mount the 2 switches under the Pro Micro

1. Grab two of your switches.
2. Snap the switches into your plate in the spots that overlay the Pro Micro (on the left side that's column 2, and on the right that's column 5).
3. Line up your PCB with the switches and solder them between the header pins

Mount the Pro Micro

You'll be working from the bottom of the board for this step.

• On the left PCB the Pro Micro should be smooth side up (facing you)
• On the right PCB the Pro Micro should be component side up (facing you)

It gets easier if you notice that on the Pro Micros and the PCBs there is "RAW" printed. The raw pin must go through the hole with the same sign.

If you made my same mistake, instead of desoldering without the right equipment you can try to just cut the dividers on the Pro Micro and detach it by breaking the header pins.

Mount the rest of the switches

Home stretch. Gently snap in the rest of the switches and solder them.

This would have been easier with a plate, I needed the help of a friend in order to have them aligned correctly.

Connect the Pro Micro

Given that sourcing the trrs jacks (even TRS if you go without leds) is a little bit difficult in Europe (I got mine from aliexpress), we are gonna connect the two Pro Micros directly.

The Pro Micros just need communication between three of their pins.

This means that the Minidox works if you connect the correct pins with a simple copper cable.

The pins are:

• Data pin on the right (pin 6 in figure)
• VCC pin, left side (21)
• GND pin, just below the RAW pin (23)

In my case I have used some old molex cable because raw copper wires tend to be very weak and break apart in a few days.

Troubleshooting

Column 2 or column 5 doesn't work (under the controller)

If you're having trouble with a dead column right over your Pro Micro it could be that you've got a short from the switch pins. Try to get under there and bend them down.

One side isn't working

• Double check if the copper wires are in working conditions and if you have connected the right pins.
• Check that the wires are insulated and that they do not touch the other pins.

End Result

Beautiful? W.

Recently I decided to change the css of my blog to reflect a vaporwave-ish aestethic.

Although I don't listen to a lot of electronic music, 2814 has been my go to music when I am programming and I go through a lot of James Ferraro's works during the day.

What is the reason for my recent obsession on vaporwave culture?

A dream that disappeared

The narrative of Western civilization has become a broken record... should we be surprised when a chopped and screwed trip through the cold war period resonates broadly?

Vaporwave creates a language to reflect on the inability to break free from the chains of an Orwellian culture.

Internet gave me a personal space, a community, heck even a lot of fun masked by a sense of purpose for the free software culture.

But from a higher point of view Internet failed us. The Cyberspace has been dead.

John Barlow on the Declaration of the Independence of Cyberspace wrote:

Governments of the Industrial World, you weary giants of flesh and steel, I come from Cyberspace, the new home of Mind. On behalf of the future, I ask you of the past to leave us alone. You are not welcome among us. You have no sovereignty where we gather.

But at a certain point in time the Cyberspace didn't want to be left alone and with its own feet headed to real world. Cyberspace blended with the Meatspace

Every manifestation of the Cyberspace into reality is some sort of virus that eats bites of our existences in the Meatspace and translates that to bytes that are stored in virtual treasure chests.

Real life communication is divoured into digital data by Facebook, Amazon doesn't stop at our doorbells anymore but creeps into our house, and sleeping is no more a function of how much we are offline but some sort of distorted self analytics.

There is no shame when a web giant plays with the emotions of the user of the platforms, or sells them.

All of that was done by drying out the so called Hackerspace and transmuting it into "Dataspace", where experiment are conducted on people by means of data and algorithms.

Data on which platforms are built and people are chained to.

Corporate smooth Jazz

Floral Shoppe traces the outlines of the mental prison in which we now live, it gives us hope of one day transcending it. It reminds us what real freedom, the freedom of the heart, tastes like.

In the novel Neuromance by cyberpunk father William Gibson the Internet is conceived as some sort of "consensual allucination". In the world where that book was written Internet is just a collective delusion.

Vaporwave forces us to recognize our helplessness with the Dataspace and for me it is a remembrace of a cyber-utopia that never got off the ground.
