i haven't, (though have one mostly finished) but as the mystery machine raced in milwaukee, the bom is probably * ~$300
$25 alternator core
$29 motor controller
$4 buck converter
$123.76 battery /2 = $61.88
1 2×6 = $5.47
1 2×4 = $3.57
$11 sheet plywood
$50 for 4 tires
4x $5 rims = $20
$11 belt
$ 5 alu motor pulley
$ 5 hardboard rear sprocket
2x $3 weldable hinges = $6 (steering hinges)
scrap metal???? $20? - steering ,shaft coupling
~$10 farm&fleet hardware by the lb
rear axle $15?
3x p5/8 pillow blocks = $7 = $21
so approximate total bom for mm milwaukee = $303
If you want to buy it for $500, go ahead. I think Id actually be pretty ok with that.
