This is a common issue with the older Lego 9V cables. Lots of sources, including myself, have experienced the same thing - this particular chemistry of insulation ages poorly, no matter how well it's stored. Cables made later, circa 2004-2006 don't seem to have this issue - the insulation is less rubbery and more plasticy, and is still shiny like new to this ...

Buy a USB to Serial adapter. There are USB IR Towers, but the drivers are only for older version of Windows. A new USB/Serial adapter, on the other hand, should be compatible with Windows 10 (Windows 10 requires signed drivers, so do your homework before buying). Use 3rd party software. For example, Brickx Command Center and leJOS are compatible with RCX and ...

Your code handling the behaviours like "Shoot 3 times if the touch sensor is triggered" or "Shoot if the light sensor is triggered" should use 'if' statements. Then, instead of always being called, the "shooting" code would append only on sensor events. After shooting, the robot would then go back to the "Driving around" part of the code. This page is a ...

I've found a seemingly broken website, but from the sources I was able to salvage these addresses, they work just fine (as far as the download goes, I did not check the contents): http://www.brickfactory.info/iso/files/9731_lego_vision_command_xp.zip -> German version http://www.brickfactory.info/iso/files/9722_extreme_creatures_1.0.zip Vision Command ...

As it just so happens, I'm physically in possession of an English Vision Command CD. I've uploaded the iso here: https://www.mediafire.com/?xo6xfjvnbzaaf7u I didn't upload and post it in that other question you mentioned since I wasn't aware none of the Vision Command ones were English, but I've also updated the answer in that other question with this link ...

Unfortunately, you cannot use the LEGO 8528 (NXT to RCX adapter) cable with sensors on the EV3. You can use it with motors though. This is because the adapter cable only connects to pins 1 and 2 on the MINDSTORMS (RJ12) connector. On the NXT input (sensor) ports, pin 2 is GND. On the EV3, however, pin 2 on the input port is no longer GND. It is used to ...

Honestly... it was WAY easier for us to find a computer on eBay! We bought an IBM ThinkPad with Windows 2000 installed on it. We won the auction with a bid of $28 and with shipping it was the best $40 I've spent on eBay! The laptop fired right up, we inserted the Lego Mindstorms Robotics Invention System disc, and voila! It installed quickly and easily. ...

The RCX uses "electric system 9V" style connectors. These are not compatible with power functions connectors. The "electric system 9V" connectors have the connections built into regular lego studs (with the electric part of each stud carefully arranged to allow connections to be made between parts placed at right angles) while the power functions connectors ...

These cable don't have anything connected to pins 5 or 6. This causes the software running on the EV3 that detects which type of motor is connected to think that there is nothing connected. Since it thinks nothing is connected, it periodically resets the output port which turns off the motor. To work around this, the unregulated motor block needs to be ...

You could try with NQC. By default it supports the Serial Tower and you can specify if you are using a USB Tower with -Susb . It works on Windows, Linux and Mac. The man page (documentation) can be found here or the in pdf format here.

This did the trick for me. My situation mirrors the original poster. http://neuron.eng.wayne.edu/LEGO_ROBOTICS/software_setup_tutorial.html There are 4 parts to this. BrickControlCenter (brickcc), a driver for the IR tower, an image of the firmware and some other piece of software called the NCQ. I did not install the driver since I was using a USB ...

I know this is 3 and a half years late, but I figured I'd throw in my two cents. Attach an NXT light sensor and an RCX light sensor facing into each other. You can communicate bi-directionally by flashing the built-in LEDs. On the RCX side, this can be accomplished by switching the sensor mode between touch sensor and light sensor to passivate or ...

There are a few hurdles to jump through. For the IR tower, you need one of the following: Infrared Transmitter with USB Cable (cheaper BrickLink listings on the part page) (uses USB instead of 9-pin). A USB-to-9-pin adapter with a compatible driver (might be hard to find at this point?). A 32-bit system to run the software on. If you don't have such a ...

Just as an aside you can also do the following: sudo ln -s /dev/usb/legousbtower1 /dev/usb/legousbtower0 That worked for me, and my challenge now is that there is no firmware :-)

Modern hardware/driver support for the RIS is limited, but it's definitely possible to get it working again. The main obstacle is transmitting programs to the Lego RCX brick. The RIS 2.0 came with a USB IR Tower, but the driver does not work on 64-bit Windows. There is also a Serial-port IR Tower available, which works perfectly if you have a 9-pin serial-...

RCX is compatible with the older 9-V system that came before Power Functions. However, since PF motors are also 9V and still unregulated as the RCX motors, a simple conversion cable suffices. The Power Functions extension wires will do (8886 or 8871) as they have on one end an underside that is compatible with the 9V/RCX system (which hence goes onto the RCX ...

How about running Windows 98 on a Raspberry Pi device and using the Lego IR USB tower that way? Here is a tutorial on running Windows 98 on a Raspberry Pi. https://magpi.raspberrypi.org/articles/run-windows-98-on-raspberry-pi-with-dosbox-x I found this, too: https://minordiscoveries.wordpress.com/2014/01/20/using-nqc-on-a-raspberry-pi-to-program-a-lego-...

Just went through this exercise on a Windows 10 64 BIT PC. RCX 1.0 w/ serial IR transmitter. I am able to get the RIS software running w/o issue on Windows 10 via compatibility mode (256 color, Win 98, etc). IR port even detects and turns on in the start up tutorial but as described above, initial download of FW clocks the RCX from 1 to 20 several times ...

If you'd rather not cut off the ends off two batteries and jury-rig in rods of hot melting glue to act as spacers, and instead have access to a 3D printer, take a look at http://www.thingiverse.com/thing:122810 :-) As the contents of the linked page have been removed, here are the original files: And of course the STL file from the archived version of the ...

If you are you using ROBOTC 2 for RCX you need to install the separate driver for windows 32bit. This driver is not included in the ROBOTC install (at least not with version 2.03). It might also be a good thing to start with a fresh install of ROBOTC 2.03.

There is no non-LEGO product that can substitute the infrared tower used for communicating with the RCX, as the USB and Serial towers use a very specific protocol that does not match that of other Infrared devices. Nonetheless, it does appear that there are schematics available for the IR Tower, courtesy of Mark Bellis: I'm no expert on low-level ...

The EV3 software is not backwards compatible with RCX 1.0. You will need to install the software from the CD-ROM that would have come with your set. If you do decide to purchase one online, you can do so from a 3rd party marketplace such as Bricklink. Be sure to install the correct version of the CD-ROM (RCX 1.0) and check to see if your operating system ...

No you can't. But IR towers are pretty cheap, especially the older serial ones (you have to add an USB to serial converter to use the latter version on modern computers)

There are partial reverse engineered schematics done by Mark Bellis here

That set has an RCX in it, is that right? I have several suggestions for you: Have you tried running the software/installer file in compatibility mode? I understand this software was designed for Windows 95 or 98. If this is the case, there is an option in Windows to 'run in compatibility mode' by right clicking the .exe file, selecting 'properties' and ...

According to Brickset and Peeron, it was released in 2001.

There are a lot of ISO files with the Robotics Invention System (RIS) software on them. Here's one link: http://www.brickfactory.info/iso/ These will only work on Windows.
