This is a nice solution! Actually, I am pretty happy with the battery I ordered. It's not that big, but it has enough power. I will post some pics with the battery installed this weekend

I fully agree. Given the price, you can't expect too much, function-wise. You get what you expect to get. But I would love to be surprised with an unexpected extra feature.

There is no differential. But a boat with wheels is equally doubtful

Review for the Power Boat:

REVIEW - 42089 - POWER BOAT INTRODUCTION Boats have never been really popular within the Technic theme. We have had our share of boats in the past, but getting a boat (or a ship for that matter) in the line-up always felt like an exception instead of a rule. The last couple of years this has changed a bit and Technic boats are getting more common. We recently got the 42074 - Racing Yacht, 42064 - Ocean Explorer and even a 42076 - Hovercraft. This new Power Boat is reminiscent of the 42002 - Hovercraft from 2013 though, due its limited size and almost exact part count (174 vs 170). At first glance, it definitely looks a lot cooler than the Hovercraft. PICTURES Pictures can be clicked to view hi-res versions. More pictures can be found in my Flickr album. DISCLAIMER This set has been provided by the CEE Team of TLG. It's not my goal to promote this set. It's my goal to give you an honest opinion about it. Therefore, the opinion in this review is my own and is in no way linked to TLG. SET INFORMATION Number: 42089 Title: Power Boat Theme: Technic Released: 2019 Part Count: 174 Box Weight: 258 gram Box Dimensions: 26,0 cm x 14,0 cm x 6,0 cm Set Price (RRP): € 14,99 Price per Part: € 0,086 Links: Brickset, Bricklink THE BOX The back of the box shows the B-model. A Hydroplane, much like the 42045 - Hydroplane Racer from 2016. CONTENTS OF THE BOX The box contains: 1x Instruction manual 1x Sticker sheet 3x Unnumbered bag PART LIST The complete list of 174 parts. COMPLETED MODEL The finished model sure looks like real power boat, a bit over the top and designed for speed. This is emphasized by the stickers on the hull. The two rear wheels are connected to the 1-piston engine and the propellor. When you "drive" the boat, the propellor rotates and the piston moves. Besides this, there is no extra functionality. Using the trans-clear windscreen is a nice detail. Fits the boat nicely. Here you can see the wheels used to drive the boat. The left-over parts. SUMMARY While I love the looks on this baby, I feel that this set could have easily implemented some form of front wheel steering. I mean, rotating the front wheel would have been sufficient. Adding a second function to this set would have turned this straightforward set into something more special. Now it's okay-ish. PROS Looks great Nice B-model CONS No steering SCORE How do I rate this set? 8 DESIGN Looks as cool as a real power boat. 7 BUILDING EXPERIENCE Straightforward, just as the boating direction. 7 FEATURES Would have been better with steering. 6 PLAYABILITY Back-and-forth, back-and-forth, back-and.... 6 PARTS Basically a collection of black panels. 7 VALUE FOR MONEY Okay-ish. 7 TOO STRAIGHTFORWARD FINAL WORDS Thanks you for reading this review.

Topic bumping is generally considered to be inappropriate. It's also in the site guidelines. When you comment on a 5 year old topic, the information is most likely outdated, the original creator might not be around anymore and the bumped topic will move up in the active recent topics. This can be confusing, because people might think it's a recent topic. So you only bump a topic when you actually have some information to add to the topic. And mini-modding is also inappropriate. Because members need to use the Report button, instead of modding themselves

I solved the sensor issue (see my comments). I will do some more testing with motors and program flow and when I face errors, I will post them here. I haven't done enough testing to properly judge whether I have made mistakes myself. Thanks! That looks great. I had some troubles with the "left_motor" not being recognizes. But it does seem to compile this way. I will invest some time to write a proper program and I will post it here, so you can take a look.

Got it, thanks! Will you be using the Triangles to attach railings or other stuff?

Yeah sure! I love to take a look.

The information we all know has been posted here. At the moment there seem to be only two sets for 2H, but most of us think there will be a big PF, or possibly PUP, set yet to be discovered/unvealed. Rest assured; this is the best topic/source for news. So you won’t miss a thing

Please don’t start rumors here. When there is info, you will find it here soon enough.

Nice render! The track looks very clean too.

The next issue I am facing is that sometimes my program has a rather erratic flow and hangs somewhere. This results in the motors turning forever. But before I bother you with this one, I will put some time in debugging the issue. Version 6.2 of my robot is done and I can start fiddling around with Python again.

When I am running a test program, I sometimes have issues with the wait function. Instead of waiting for one second, it seems to be waiting forever, making the robot go berserk. I decided to implement a touch sensor the abandon the program when things go south. But my robot doesn't recognize my sensor. I have tried every port, multiple touch sensors, but it says that the sensor is not connected. This is my code: from ev3dev2.motor import LargeMotor, Motor, SpeedPercent, MoveTank from ev3dev2.sensor import INPUT_1, INPUT_2 from ev3dev2.sensor.lego import TouchSensor touch_1 = TouchSensor("spi0.1:S2") When I used INPUT_2, instead of "spi0.1:S2", I got an error message stating that "spi0.1.S2" was not connected, so I reckoned I could use the stacked BrickPi notation. Maybe I need to wait a bit before posting it here, but it might help others with the same issues. I have found the solution. You need to define which port it is, before creating the touch sensor, so this works: port_2 = ev3.LegoPort("spi0.1:S2") port_2.mode ="ev3-analog" port_2.set_device = "lego-ev3-touch" touch_1 = TouchSensor("spi0.1:S2")

I have been trying to get the polarity to work, but I am still drawing a blank. Since I am working with a stacked BrickPi, my syntax is a bit different. I can't use the "spi0.1MC" string in the polarity function. wheel_a = MoveTank("spi0.1:MC", "spi0.1:MH") wheel_b = MoveTank("spi0.1:ME", "spi0.1:MB") wheel_c = MoveTank("spi0.1:MF", "spi0.1:MG") wheel_d = MoveTank("spi0.1:MA", "spi0.1:MD") wheel_a.set_polarity(LargeMotor.POLARITY_INVERSED, ["spi0.1:MC",]) After tinkering a bit, this seems to work: motor_a = LargeMotor('spi0.1:MA') motor_b = LargeMotor('spi0.1:MB') motor_c = LargeMotor('spi0.1:MC') motor_d = LargeMotor('spi0.1:MD') motor_e = LargeMotor('spi0.1:ME') motor_f = LargeMotor('spi0.1:MF') motor_g = LargeMotor('spi0.1:MG') motor_h = LargeMotor('spi0.1:MH') wheel_a = MoveTank("spi0.1:MC", "spi0.1:MH") wheel_b = MoveTank("spi0.1:ME", "spi0.1:MB") wheel_c = MoveTank("spi0.1:MF", "spi0.1:MG") wheel_d = MoveTank("spi0.1:MA", "spi0.1:MD") wheel_a.set_polarity(LargeMotor.POLARITY_INVERSED, [motor_c,]) wheel_b.set_polarity(LargeMotor.POLARITY_INVERSED, [motor_e,]) wheel_c.set_polarity(LargeMotor.POLARITY_INVERSED, [motor_f,]) wheel_d.set_polarity(LargeMotor.POLARITY_INVERSED, [motor_a,])

You are always welcome to post it here, so please don't hesitate. Happy Holidays (a bit late). This!

I have not tried disassembling the stretcher. I do see the image on the box, but taking apart the stretcher doesn't feel right. I will try it though. Thanks.

That sure looks like a Zeppelin...of some sorts. Proceed

I hope it will be more interesting than only the base of the robot. Hopefully I will be able to finish the base in the next couple of weeks. After that I need to start thinking about the upper structure. I am planning to use the big (banana) worm gears as the top of the base, so I can put different attachment on top of it. Not sure how this will work out, but that's what I have in mind at the moment.

Slowly, but steady, I am getting there. It's my life's work, but given my age and building speed, I probably need to pick up the pace

I have found the topic and I am not sure about it It could be considered a Zeppelin, but it's very doubtful.

Hi. Please include a link when you make a post like this. It will make it easier for me to take a look I have made it clear that we are NOT looking for unrealistic futuristic sci-fi designs. I have already turned down a Blade Runner vehicle and an X-Men like Helicarrier is obviously not allowed either. I am not providing any examples. People need to stop crossing obvious boundaries and just make a plane or helicopter, or something that will obviously fit the contest. Sorry for sounding harsh, but it’s not that difficult to pick a valid entry. And when in doubt, ask before you start building.

Hi Scandinavian from The Netherlands It's so stupid that sets already hit the shelves and essential stuff is not available yet. And seriously....why do you need web updaters?! When sets leave your warehouse, automatically make that stuff available. Being a software architect, I just can't get my head around this
