![]() This time they came with an automatic transmision, or "Heavy Duty Automatic transmission 1.0" (HDA 1.0) as they have called it. |
In its own authors' words,
"We're proud to present the FIRST heavy duty 3 speed automatic gearbox made out of lego. By automatic, we mean that it shifts by itself with the help of a torque sensor. The function of the gearbox is entirely mechanical and absolutely reliable.
Not that we really figure out how does it work, from the images/video made available, but we should understand the secret is also part of their business...

Dimensions:
- Lenght: 18 studs
- Height: 9 studs
- Width: 10 studs
- Weight: 250 grams
Gear Ratios:
- 1st speed 3,00:1
- 2nd speed 1,66:1
- 3rd speed 0,91:1
As for the characteristics, lets say it is not properly small neither light. So it won't fit on everyone's LEGO car...
The HDA 1.0 is selling ate LPE Power, for 75€.
I should say we have already seen these guys selling more expensive gadgets...

The do not publish their mechanism. But do you know if you can unbuild it if you buy it? or are the pieces "stuck" together? :)
Any one has bought it? I'm kind of curious!
