NXT® plugs crimping tool

Unfortunately regular RJ12 crimping tools are not suited for them because of their offset latch. Since adapted crimping tools are not available you need to hack a RJ12 one... Here is how I modified mine. This is just for illustration purpose and to give you ideas on how it can be done, since there are so many different models.

See also Michael Brandl crimping tool. R J McNamara modified another model of crimping tool, see here. Using the crimping tool Don't make too long cables. 1 meter is about the maximum recommended length to guarantee proper working of all sensors and motors connected to your NXT.

EV3: Creating a Console Cable

The cool thing is that the kernel has been configured to output diagnostics data to the first sensor port (S1). You can easily access this data by using a USB to serial converter. You can make one yourself or if you’re not that good with soldering or hacking cables, you can wait another week or so and buy a pre-made console adapter from Mindsensors. There is a mistake in this tutorial!

You should use the red wire instead of the black wire as ground. What you’ll need An NXT or EV3 cable you don’t mind seeing get hurtA cable cutterA soldering ironSoldering tinA wire stripper or small knifeA USB to UART bridge dongle. Step 1: Preparing the cable Step 2: Soldering it together: Note! Step3: Testing your setup Now that you’ve made a dongle, it’s time to test it out.

Lucky for me, nothing blew up when I hooked up my converter cable to the computer and EV3. I used PuTTY to connect to the EV3. Willkommen auf dem Wiki zu LEGO-Mindstorms EV3, NXT, und RCX [EV3 und NXT Wissen] WiFi dongle for EV3. Once these has generated some questions among the community, I decided to come up with some information also here at TBs Similarly to what happened with BT dongles for NXT, there is a very limited choice regarding working WiFi dongles for EV3.

WiFi dongle for EV3

Until someone changes something in the firmware/VM executable there is only one WiFi dongle that will work with the EV3. It is the NetGear WNA1100 (with USB ID 0846:9030). You can find these dongles at the moment at several sources, and eventually at your local retailer too. (look at the respective website serving your country) Amazon.comLEGO Education (which charges a premium price for reselling this...) Unfortunately none of the small sized WiFi dongles in the market, or even any other large one like the NetGear dongle, will work! Be aware, before you get to buy something else!... PS: I've gathered this information from an MCP expert with such firmware topics. Mindboards/ev3sources. LEGO MINDSTORMS EV3 Source Code Available.
