  1. They will use the 9v connector for all future products, they showed their version at Schwabenstein 2x4: https://youtu.be/CJjVDErcjJY?t=600 So not quite extinct. You can always connect 9v and PF with the PF extension cables lbg end, for PU you can get adapters from PV-Productions, Aliexpress or just make you own.
  2. You can get cables for about 2$ each here: https://de.aliexpress.com/item/1005004291123085.html I have tried "crimping" (frantically pushing the metal parts in with a screwdriver), i have ordered original PV-Productions extension cables (which fit very badly), aliexpress extension cables ironically had better quality and fit. (https://de.aliexpress.com/item/32871195908.html) The new connector PV-Productions uses does intrigue me (pcb based), this seems like a cheap and efficient way of creating a pup connector.
  3. Antons Mindstorms Hacks has built some custom sensors and is also selling some related components on his website. Here is a laser distanced sensor he built: I don't completely like him since he is also kind of ripping off Mindsensors's breakout board, and then acting like he invented something completely new while it has been available for some time from Mindsensors, that's what happens when there is a personal financial advantage in play. I might be doing him wrong though, he might not have know about it.

    Theoretically, but you can still find cables like these at around 20$ for 10: https://de.aliexpress.com/item/1005003097712820.html?mp=1 Ports and just the Connectors are also available: https://de.aliexpress.com/item/1005003097614373.html
  5. I have recently got one, it works, I have not thoroughly tested it yet. As far as I can tell, the ports don't seem to have a high fuse (unlike Lego), also I am still puzzled by the six pin PF connector, I have no clue why it exists and what it does.
  6. I recently tried measuring the resistance of a thermistor using the .resistance() method, the results are sadly not accurate. I measured the resistance with a multimeter and it showed 100kΩ, while the different EV3's all showed something between 330kΩ and 360kΩ. Even with no resistance the EV3 shows around 10kΩ resistance, so the results are not off by a fixed amount, but the results are repeatable. Here is the code I used: #!/usr/bin/env pybricks-micropython from pybricks.hubs import EV3Brick from pybricks.iodevices import AnalogSensor from pybricks.parameters import Port ev3 = EV3Brick() termistor = AnalogSensor(Port.S1) x = termistor.resistance() print(x) Any help, explanation or like a formula to calculate the real resistance would be very appreciated Thanks
  7. Akiyuki has als made a small version of the Lego Motorized Spacecraft Elevator to show the mechanism. I made a Studio file for it and you can download it here: https://drive.google.com/file/d/1GsPcGk2v0sZLN-aItFdlrfxKWyw-2d37/view?usp=sharing

    Hi everyone I have recently started making PUP/PF/EV3 adapter cables out of cut up knockoff pf cable, 3D-printed PUP connectors and self-crimped EV3/NXT cables. There are also PUP connectors for sale on AliExpress but TLG seems to use some sort of crimping tool to attach the cable firmly, better than I could ever do with screwdriver. Has anyone any knowledge on what tools the use and if they are able to be purchased? Any information on this topic would be appreciated.
