wow naman!

at least malapit na pala matapos.
I've always wanted to have one too, kaso I know time will not
permit me to build one. I am really excited to see some pics

I know malaki talaga ang dapat na budget mo sa ganyang projects.
Konting tipid para makaipon ka ulit

ganun na nga lang tipid tipid tipid unless mayroong gustong mag-invest...

cguro 2 trabaho mo kaya wla kang time, ano?....

yes, may trabaho ako at may maliit na business
and I am doing a continuing education.
Also, I am on training most of the time (lately)

kung may time lang ako, i would be really happy to help
in some part or in any other part hhaaay hirap buhay

Ok! ako ang test pilot (NFS barangay title holder)

Siguro kung pwede dapat stepper motor drive, lagyan nalang ng carbon graphite composite gears para umarangkada at 100km/hr in 3 sec. he he he he

Maganda kasi pag stepper motor- accurate, pricise, programmable etc etc.....very controllable kasi, pwede autopilot, pwede hook-up sa gps, pwede tawagan, pwede kausapin....lahat na siguro na autofunction pwede....ha ha ha ha ha nakakalokaa!! pag stepper motor ang gagamitin!!!

problem lang se stepper motor madali nang mag-cog dahil sa dami ng magnetic poles. yung 6W na stepper motor halos hindi na kayang iikot ng daliri kahit patay, pero yung 2kW na brushless motor pwede pang ikutin ng daliri.

going downhill sayang yung potential to kinetic energy conversion, mahihirapan ma-convert kung stepper gamit.

isa pang advantage sa Brushless DC at Permanent Magnet AC parang CVT after ng rated speed.

pero pwede ring gawin sa Brushed DC using Separately Excited Windings, field weakening ang ginagawa. kailangan nga lang designed yung brushes nung motor for that, kung hindi kasi, ubos kaagad ang brushes.

ang mahirap lang sa kanila, controller at source ng permanent magnet. pero sila yung pinakamataas na power to weight ratio. yung 350W brushless, is nearly as large as 150W brushed. depende na rin sa gumagawa at nagdesign.

how about soleniod drive, gawa tayo ng V8 engine na soleniod drive

ha ha ha i dont know soleniods he he he

hehe. kailangan din ng timing controller. merong pneumatic vesions ng V type engines.

problem with them kasi, linear to rotary motion. may point na hindi optimized yung torque delivery. solved 'to using Field Oriented Control with Brushless DC or Permanent Magnet AC. ang force ay laging perpendicular sa rotation, maximum torque lagi.

how about waveshaping at go-no-go timing don soleniod triggering.....he he he

okay its becomming wild now...yah i think brushless is good incorporating lightweigth high gauss neodymium magnets

hope we do it first he he he

china neodymium is very cheap.

a Danish Mechanical Engineer (from another forum) suggested a mechanical circuit that looks like the dual of an Electrical Boost Circuit. consisted of springs and a clutch. complicated nga lang daw i-control yun.

Here's one that supposedly runs on compressed air. Under development pa yata.

2 company na ata gumagawa ngayon niyan, isa sa Europe, yung isa sa Australia. mas gusto ko yung design dun sa Australia, based on Wankel Rotary Engine. nakalimutan ko na yung names ng comapny.
