Introduction: BECOME a MAD CYBORG... Part Human, Part Dead Computers (UPDATED!!!)

About: I'm Mario Caicedo Langer (M.C. for short), a Colombian STEAM educator living in Azerbaijan, BSc in Naval Sciences and former Navy officer. I am a CAD and 3D Printing enthusiast and an artist specialized in jun…

M.C. Langer was an ordinary DIY artist until a bizarre accident (papercut printing an instructable) crippled him physically and mentally. Now, he had to rebuild his damaged body with dead computers pieces for the only target in his twisted mind: REVENGE AGAINST INSTRUCTABLES.COM!!

(What?? It was a big papercut. And It hurt so much. And the instructable was the Bacon Cheesecake Brownies recipe. I'm barely alive...)

If you want to join me in this insane quest, you will need your own cyborg attachments, so I will teach you how to make props of a mechanical arm (the clamp can be activated by spring action or motorized action, I will show both possibilities), a face plate (the eye lights) and the battle vest (the chest plate lights too).

And the best part? The props are made 90% of dead computers pieces. You will find here plastic cases of almost any kind of computer parts or accessories related with computers, PC and MAC. (Curiously, the only thing you will not find here is a mouse).

Well my minions, ready to take over the world?

Step 1: A Lot of Useful and Important Blablabla Before Starting...

If you want to make a desk toy for your mom, your old computer is OK. But, if you want to build a big bad bionic armor, you will need all the computer pieces you can get. And you can find the good stuff and these places:

1. Junkyards
2. Computers technical service sites
3. Trash cans, specially when they are located in front of computers technical service sites and computers stores.

Exactly, what are we looking for? Everything computer related: printers, keyboards, CPUs, screens (and, specially, screens bases), joysticks, speakers, scanners... everything!!

Try to always have an important amount of raw material (plastic junk, computer pieces, damaged toys) in your workshop. It will save you of travel for all de city looking for materials.

Starting every step, I will tell you what materials are equired for the prop. But remember: loose engineering. It's improbable you can make an identical prop, because you'll find different pieces than mine. For the same reason, I can't tell you exactly where to drill and put screws and nuts (and you will have to put a lot). So, use your creativity!

For the moment, you will need this:

- A lot of computer pieces
- A lot of screws, nuts and metallic rings
- iron angles
- Instant glue
- tin soldering
- wire
- electric screwdiver

- rotary tool (VERY IMPORTANT!!)
- soldering iron
- tweezers
- screwdivers (if they are electric, better!)
- pliers
- heat gun

Along this project, you will need to do these actions:

- Disassemble printers, speakers, scanners and everything assembled.
- Drill and join plastic pieces using screws, nuts, metallic rings and angles.
- Cut, drill, burnish and work the plastic pieces using the rotary tool.
- Cut the spare parts of screws.
- Mold, bend and melt the plastic using the heat gun.
- Tear down plastic pieces using the pliers.
- Stick foamy or another padded material at those prop sites in contact with your body.
- Solder wires.
- Use the instant glue to fix the nuts on the screws, specially in the screws than acts as axis.


1. Always use personal protective equipment (goggles, dust mask, gloves and others), specially when you use rotary tools.
2. Work in an area with good ventilation
3. The things warmed by a heat gun or worked with a rotary tool could be very hot. Be careful when manipulate!
4. Getting computer pieces, don't dig deeply in public trash cans (only use the shallow pieces), and be careful when you dig in a junkyard. Use protective gloves. Don't use pieces found with hospitalary waste or in contact with another biological or chemical source of risk.

Well, as the great Tallahassee says, TIME TO NUT UP, OR SHUT UP!

Step 2: MECHANICAL ARM (option A: Spring Action)

NOTE: Before start building the arm, first read the Step 3 "MECHANICAL ARM (Option B: motor action)".


- Damaged printer (the main piece of the arm)
- Other printers pieces and cases
- Three screen round bases (two with entries for the elbow, one perfectly round for the clamp base)
- CPU frontal piece
- Aluminum pipe
- Five speakers (four for the clamp fingers, one for the base of the clamp)
- Springs
- Plastic handles (I use a plastic spool of thread and the handle of a toy shovel)

Step 3: MECHANICAL ARM (option B: Motorized Action)

I think an instructable is not only to show the right way, but the wrong, too. The great Thomas Alva Edison said he had found 1000 ways of how not to make a bulb. It's funny (but very frustrating at the beginning) to find the wrong way.

Well; generally, the spring clamp is not a bad thing, but It was for this project. I start with the spring option because the feeling of grab the things, and the concept of  "simple solutions are the best". And it's not a bad idea, but I forgot something: the total weight of the arm. It's very hard to lift a heavy arm and squeeze springs at the same time. Well... back to the workshop!


- Electric screwdiver (it has all you need: reduction box, a good motor and a reversible switch. You only have to hack it and extend the wires).
- Printers adaptator.
- Joystick (it will be the new handle)
- Metallic angles
- Speaker (with battery box for 4 AA batteries)
- Switch
- Wires
- Electric isolator
- Plastic pieces



- A scanner
- Two old PC speakers
- LCD DELL screen back section
- PC screen base
- MAC screen base
- Printer piece
- Thermo top
- Battery box (for 4 AA batteries)
- Switch
- Wires
- Three green LEDs
- Metallic case of an old alarm clock (with de glass)
- Deodorant cap
- Plastic bottle cap with nozzle
- Metallic angles


Curiously, the face plate with ocular implant is the accesory with less parts, but more modeling with rotary tool and heat gun. It will be connected to the battle vest, and use its power source.


- Printer piece
- Web cam
- One red LED
- Wires
- Elastic band
- Duct tape

Step 6: Fully Armored!!! Now, Time to Paint And... REVENGE!!!

Before painting, I wanted to take some pictures, scare people and get fun.

I take pictures of the armour unpainted and painted. The choice is yours!!

Well... what are we waiting for??? LET'S GET DANGEROUS!!!!!!

Step 7: UPGRADE: New Mechanical Arm (Power Clamp 2.0)

I used an old printer for the arm, in the spirit of the Dead Computer Contest. But it was too heavy for the next target: Imaginna, the design fair in Bogotá. So, I modified it, using a PVC pipe instead of the printer, and creating a new control and a new handler. The clamp is still the same. Now, it's more versatile, more ergonomic, lighter and easy to carry.

And what about the Plasma Gun? Wait for my next instructable!!!!!

Step 8: UPGRADE 2: WEAPONS SYSTEM (And Halloween Fun!!)

For 2010 Hallween season I made a new arm, with machine gun, plasma blaster an missile launcher. How? I used my light gun:

And I insert it in a PVC pipe with pc bases, like the arm. The machine gun and missile launcher are from my SPD battlizer.

I put some pictures from Halloween events. It was a great time (and girls love the cyborgs!).
