If you’re a regular here at The Lego Car Blog you have doubtless seen dozens of creations powered by a little programmable bluetooth battery brick; BuWizz.
Since their first Kickstarter featured here a decade ago, BuWizz have moved through three iterations (and from four to the full five stars in our Reviews), and are now ready to launch the fourth generation of the amazing programmable powerbank. This is the BuWizz 4.0 Ultra.
Retaining the same dimensions, 100m bluetooth range, and immense power as before, the new BuWizz 4.0 Ultra features four Power Functions ports, one of which can toggle to control Powered-Up components. With its output programmable in increments, you no longer need a Servo Motor for precise steering or gearbox positions, as any Powered-Up Motor can act as a servo.
The BuWizz 4.0 Ultra also debuts an in-built three-axis gyroscope for the first time, allowing a vehicle to maintain a heading or radius without wobbling about (which is perhaps something of a worry here at TLCB Towers as the Elves have used many a BuWizz-powered build to flatten their colleagues, even with dodgy steering), and four programmable fibre-optic ports with integrated LEDs, enabling head and tail lights, flashing beacons, indicators, and more to be programmed into the sequence.
Rechargeable via USB-C, the new BuWizz 4.0 Ultra features a Li-Ion 2400mAh replaceable (not inaccessibly sealed, hurrah!) battery, allowing for easy replacement and continued reuse. And with original BuWizz 1.0 units still going strong after ten years’ of service, we’re sure the 4.0 Ultra could power decades of creations.
Expected to cost €229, the BuWizz 4.0 Ultra Kickstarter campaign opens on November 4th for three weeks, and you can find all the BuWizz bluetooth bricks and motors currently available via the BuWizz store. The BuWizz 4.0 Ultra will hopefully appear there (and in creations featured here) very soon…
