NETGEAR WMA1100 is the only working WIFI dongle for EV3

At TechnicBRICKs there is also some good information to be found with regards to the EV3.

Here is a re-post about WIFI Dongles and EV3: (thanks Fernando)

Similarly to what happened with BT dongles for NXT, there is a very limited choice regarding working WiFi dongles 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.

USA (19,95 USD) Amazon.com
Europe (12,99 euro DE, 13,95 euro NL, 11,90 pound, UK) pixmania.com (select your country) then search for "netgear-wma1100"
USA (39,95 USD) LEGO 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!

It has to use a specific Atheros chipset (one supported by the ath9k_htc linux drivers, which limits us to around 20 or fewer devices) and then the VM executable checks for a specific USB device ID (unique to the NetGear dongle) before loading the atheros drivers so no other atheros-based dongle works either. Dongles that use Ralink or Realtek chipsets do not even have driver support in the standard firmware image.

Be aware, before you get to buy something else!...

Celebrating MINDSTORMS with a Remix - Part 3

The ROBOTMAK3RS continued their celebration of the 25th Anniversary of MINDSTORMS through these Fall and Winter remix projects. Each ROBOTMAK3R was tasked with selecting one LEGO set of their choice and combining it with a MINDSTORMS set. Below are the five amazing models they came up with. Braill3 by Jerry Nicholls Braill3 is an EV3-based LEGO Braille bricks reader. This robot uses its fingertip, made from three touch switches, to read messages written using the LEGO Braille bricks and will speak out what it detected. If it sees a simple maths problem it will attempt to solve it and give the answer as well. To learn more about the process of creating this machine, read Jerry's blog . Braill3 can be viewed here . Set Review: The Braille Bricks set is well thought out. The ratios of the letters is suitable for general use and the addition of some punctuation and arithmetic operators is excellent. There is a card showing what bricks there are and their quantities, but no form of sort...

Celebrating MINDSTORMS with a Remix - Part 2

The ROBOTMAK3RS continued their celebration of the 25th Anniversary of MINDSTORMS through these summer and fall remix projects. Each ROBOTMAK3R was tasked with selecting one LEGO set of their choice and combining it with a MINDSTORMS set. Below are the five amazing models they came up with. Remote controlled material handle r by Jozua van Ravenhorst (aka Mr Jo) This remix combines the LEGO Technic Material Handler (42144) with MINDSTORMS EV3 (31313) It uses the power of pneumatic cylinders to move objects around. By using a bluetooth remote control, very precise movements can be made with this model. Touch sensors in the base chassis prevent the turret twisting the cables that go through the turntable to much. The program has several protections to prevent over pressurizing the system for each of the 3 individual pumps and valves that control the 2 booms and claws. The real version of this machine is mostly used in waste material sites to bring the material to machines that sort and...

Celebrating 25 Years of MINDSTORMS

In celebration of the 25th Anniversary of MINDSTORMS, we take a trip through history. Please also visit ROBOTMAK3RS Community every week as we highlight different projects all through 2023 in celebration of the anniversary. Some of the early history is based on the content shared by Coder Shah in our MINDSTORMS EV3 Community Group . Some of the text and links may have been edited from his original posts for consistency and clarity. 1984 - Kjeld Kirk Kristiansen watched a TV program called "Talking Turtle," where MIT professor Seymour Papert demonstrated how children could control robot "turtles" using LOGO, a programming language he developed. 1988 - The collaboration between MIT and LEGO resulted in LEGO TC Logo in 1988, which allowed students to control LEGO models using computer commands. The video shows Papert demonstrating TC Logo. 1990 - LEGO TC Logo was hampered since the robots you built had to be tethered to a personal computer. LEGO and MIT...
