In Search of the Perfect PC Game Chair – #2 (Playing with Explosives)

This is installment two of my PC game chair build, started here.  Interested? Follow along here.

Step 2: Playing with Explosives

Having gotten my prize home and found it free of freeloading mice etc., I set about making it safe to use as a piece of home furniture.

Choosing a seat from a high end luxury car presents as many challenges as it does benefits.  According to the electrical diagram (and assuming they are still functional), my lovely seat has 8-way adjust-ability (including lumbar support! oooooh, ahhhhh), seat heating, and a passenger restraint and seat mounted airbag!  While the adjustment features would be way cool to maintain, the heat and the two small explosive devices (seat belt and airbag systems) had to go.  Nothing like fire and an actual explosion going off during a video game!  So, I turned the chair over, got out the tools, pulled up the schematic and started digging.

Disassembling the wiring harness (that harness tape is a sticky mess!) and following the diagram, I quickly identified that I could keep the adjustment buttons and functions while ditching the heater control, seat weight sensor, and a myriad of other junk.  Removing the seat belt safety restraint (explosive #1 and the belt on the far side) was a simple matter of unbolting the components, while getting the air bag out (explosive #2) was a little more involved.  I located it’s lead wire, snipping it at the base of the seat, for safety.  Then, I gently (crowbar) pulled the back panel of the seat off, removed some of the upholstery clips, and removed the airbag from the right side of the seat.

After putting the remaining seat back together, I went back to the schematic and looked up the fuses for each of the remaining seat systems.  Determining that the seat motors run off of 12V (duh) and pull a maximum of 30A (yowza!) I went to trusty Amazon to find a 360W power supply and a suitable AC chord (Prime membership can be dangerous!  and useful ;-)).

So, after much activity, I have an explosive free seat and a power supply en route to get it running.  Will it work?  Will the magic smoke escape? Can I design a base for it that doesn’t look like the cubist exhibit at the LA County Museum of Art?  Stay tuned…

In Search of the Perfect PC Game Chair – #1 (Taking a seat)

image

As many coworkers of companies past can attest too, I’m something of an ergonomiphile (and yes, I’m making that up).  I’ve probably tried 12 different office chairs and 5 times as many computer / office arrangements in as many years, playing with chairs, input devices, monitor arrangements, lighting, and a multitude of other things.  One thing in particular I have never been satisfied with is in finding the perfect seated PC chair.

In full disclosure,I have owned more than a few commercial chairs, and in recent years (for work, anyway) resorted to standing desks and the occasional kneeling chair for my PC needs.  But when I come home from a day of work and just want to relax and play some PC games, the average chair just wont do.  I’ve tried $150+ office chairs, kneeling chairs, plugging my PC into the TV and playing from the couch, and just cant seem to get it “right”.  So, faced with this frustration and in need of a new chair for the new apartment (came with the new wife 😉 ), I’ve decided something custom was called for.  And the PC-Car seat quest was born.

Step 1: Take a Seat

This is not a new idea, many have mounted car seats to PC chair bases , and even more have built race car and flight sim seats using similar techniques.  However, the later does not suit my purposes (purpose built, not good for every day use) and the former has one key problem – it uses the same base (casters, frame, and piston support) that most often fails when I use an office chair. So, time for something a little different…

The first step was getting a seat.  After a little research, I opted to visit my local pick-your-part yard and go hunting.  $6 got us in the door ($3 each, the wife came along for moral support and aesthetic approval 😉 ) with a bag of tools slung over my shoulder and we started walking among their rather extensive selection. After some rooting and seeing a wide array of candidate seats, a number of important criteria emerged:

  1. Leather is better (easier to clean and better looking to boot!)
  2. interface between the seat and the car floor needs to be as flat as possible (note, many seats have attachment points that are perpendicular to the plane of the floor.  This would make mounting anything to the seat difficult later)
  3. Passenger seats are probably better (A – they tend to be in slightly better condition and B – their inner workings have likely been used less, making them more reliable).

After much searching and wrinkled noses (don’t ask), we stumbled upon this lovingly restored (cough) 2003 Jaguar S Type…

.. and it’s intact, incredibly comfy,  leather seats!

Getting the seat out of said Jaguar was something of a challenge.  The seat was in the aft position on its rails making getting at and releasing the back two bolts a challenge.  But a little blood, sweat, and a borrowed 15mm box end wrench later (thanks loaner guy! whoever you were…) we had it out and headed for the cashier.

Now, LKQ’s pricing guidelines were anything but clear (I even called ahead and was told to expect a $40 hit), so when the greasy fellow behind the counter flatly asked “is it electric?” (yes), and said “$100”, I was a little set back.  But I was too deep in car blood to walk away now, so I quietly paid the man and hauled my prize to the back of my jeep and took it home happy knowing I had some electrical work, frame design, and much PC gaming bliss ahead of me.
