About 15-20 minutes. I never timed it. It's 850 MAH 3 cell. The demand on the battery is low. There is not that much time on the throttle. It spins the tire at less than half throttle.

The first motorcycle was great but it needed more range. So I rebuilt it with a better radio. But then things sort of got out of hand. First I accidentally ordered a brushless ESC. Then I had to get a motor right? I looked at the motor and realized it might work for an even faster motorcycle. The first bike was all Lego and I'm not claiming any Lego records so cheating should be ok, right? Just having fun. How much cheating is too much? What about 3rd party lego compatible stuff like Buwizz and Sbrick? Sometimes I use a few small non-lego springs(like on his legs). Cutting grinding or reshaping Lego seems to make people mad, but Lego doesn't make the pieces I need sometimes and the hobby radio just works really well.

4 wheel drive from 3 XL Lego motors lets all 4 tires spin. Independent suspension in the rear. Front suspension and more power coming soon, this is a Work In Progress (WIP) I am not able to upload photos for some reason. More in the video

Sentry mode turns the gun in a 300-degree radius searching for targets within range. When a target is detected it stops rotating and shoots. Target tracking follows the IR beacon in 360 degrees. Once it's fixed on the beacon it fires.

Johnny is having a groovy roller disco flashback. Watch his hips work it as he twists and turns on his path to a groovier dimension. A servo motor shifts his upper body and hips back and forth altering his balance allowing him to turn like a real roller skater. The hip/upper body motion moves his arms up and down. Two l-motors propel him with tank steering for additional agility. These functions are programmed as sequences to an SBrick.

The servos have a lego axle connector. They are a great product if you have a hobby radio. I got 4 of them for less than $25 This video has more info and links.

That is Max, he is practically a seeing-eye dog: Opening doors is one of his many talents. He would only grab ski bot if I asked him to.

Downhill skiing robot uses 2 servos so he can move his skis side to side and bend his waist pushing his poles into the ground. He can actually ski down a hill with control. I found that third-person skiing is quite hard though!

Huge Lego spider creeping around under the house. Thanks for the suggestions!

Small scale lego R/C pink Cadillac tank. Borrowed from my daughters Lego Model 10260 Downtown Diner and customized with tank treads and remote control. It's dimensions are 14cmX10cmX9cm.

I bought a box of misc springs so I can make my own shocks on axles. Springs about 4.6 mm to 8 mm Internal Diameter work . Like Technic Racer said 2 of the 8 springs on this walker are medium stiffness red lego shock from Ebay

This is the second Lego Big Dog. The object on this one is to achieve maximum running speed and stability with 4 legs. I would like to work up to a 4 leg model that can change gates from running to jumping and is steerable. The next step is steering without falling over on four legs.

Could you point me to some instruction creating software?

That is a great idea! The next spider should have a web and something struggling in it.

Creepy huge spider vid. This spider is using the Klann leg linkage geometry. Dogs hate this thing. They won't let it face them.

The relay separates the receiver circuit from the motor circuit. The battery does not receive a load because the relay opens the circuit between the battery and the motors. when the relay is off the motors are not connected to anything.

It's only good for a freewheel. On the front wheels of a rear-wheel drive. Like in this

After ages of staring at bits, I finally found a way to integrate some ball bearings into some lego wheels.

I had a fever dream.

kludging is what I do best.

One day I was wanting to run 8 motors on one Sbrick but you can't do that. So it occurred to me that a relay would be a common solution for increasing the power capacity of an electronic signal. They are also fairly cheap. So I got a relay and as an experiment ran 14 lego motors and a power drill controled by one channel on a Lego IR reciever. Is this dumb? Is it already a common thing and I live under a rock?

Yes, So complying with the law is straight forward but we are guessing when it comes to youtube. My content is not for kids. My viewers are not kids. It's probably best for the Lego community if we try different approaches and see what works. I will cover the "not for kids" route. Lets all report back here about what happens.

Here is the actual bill https://www.law.cornell.edu/uscode/text/47/231 This is what you can't do: (1) Prohibited conduct Whoever knowingly and with knowledge of the character of the material, in interstate or foreign commerce by means of the World Wide Web, makes any communication for commercial purposes that is available to any minor and that includes any material that is harmful to minors shall be fined not more than $50,000, imprisoned not more than 6 months, or both. Don't make content that is harmful to minors and you are fine in court. Who knows about youtube?! The law says nothing about toys.

That is definitely true. Your channel could be deleted for no reason. I still say if kids don't watch your videos you can't be doing anything wrong and you should not worry about coppa. It's like leaving your house you could be deleted for no reason and all you can do is figure out what rules to follow and what rules to break. I don't see any other choice but to try to do the right thing and keep going.

You tube " How old is a kid? The age of a "kid" in the United States is defined as anyone under the age of 13. However, the age of a kid may be higher in other countries, so consider the factors described above as appropriate given how kid is defined in applicable laws in your country, and consult legal counsel if you have additional questions. " Google search "coppa age eu" result: 13 Most EU countries (including the UK) set this age at 13 (taking the lead from the COPPA rules).

These guidelines are worded to Imply preteen activities and language: Youtube " According to the FTC’s guidance on COPPA, a video is child directed (which we call “made for kids”) if: Children are the primary audience based on the factors described below. Children are not the primary audience, but the video is still directed to children based on the factors below. When deciding whether or not your channel or video is made for kids, you should consider various factors, including: Subject matter of the video (e.g. educational content for preschoolers). Whether children are your intended or actual audience for the video. Whether the video includes child actors or models. Whether the video includes characters, celebrities, or toys that appeal to children, including animated characters or cartoon figures.

Whether the video includes activities that appeal to children, such as play-acting, simple songs or games, or early education. Whether the video includes songs, stories, or poems for children. Any other information you may have to help determine your video’s audience, like empirical evidence of the video’s audience.
