Total Cost
The total cost for this complete system was $692. The only discount was a second hand 17” monitor. Everything else was purchased at Amazon or my local hardware store. Since there was plenty of trial and error, some resources were wasted, so the total cost is an estimate only. My cost target was $450, so I totally missed that mark. The break down cost is shown below:
- Wood $15
- Legs (angle Iron) $18
- Trim $20
- Hardware, misc (I added everything here) $30
- PC (refurbished off-leased Lenovo) $70
- CPU upgrade $15
- Memory upgrade to 4g $14
- Graphics card $45
- Wifi dongle (optional) $20
- 17” 4:3 monitor $15
- 27” IPS 16:9 monitor $165
- 1/8” Acrylic for backboard $16
- ¼” Acrylic for playfield $31
- Sound system $45
- Bang! board $30
- Plunger $17
- Plunger pot $8
- 24V invertor $7
- Vibe motors $8
- Solenoid $12
- Cabinet paint $18
- Trim paint $7
- Plastic paint for bezel mask $6
- Illuminated buttons, 7 ea. $22
- Standard arcade buttons, 2 ea. $6
- KL25Z evaluation board $15
- Exciter, 4 ohms 2 ea. $17.00
Future Development
As mentioned, I am playing with Flight Distance Ranging Sensor for a plunger system, upgrading audio for enhanced haptics, and redesigning the Bang! Board for more DOF outputs. In addition to all that, I am also playing with a 5” LCD HDMI module that I hope to use as a low cost DMD. This 5” device cost ~$30 on Amazon and has a native resolution of 800×480. It will fit neatly straddled between both speakers on the back box, but I’ll need to redesign a new back box. I am leaning towards a trapezoidal shaped box so that it has full retro style appeal. I expect my net system cost will go northward to just under $770.
BTW- They also make a 7” monitor for slightly more money. This larger version would suite well for full size cabinets.
