Sumo Bots Event #36

Edit: SumoBots fell through. Sorry folks.

AnnaGerber commented 10 years ago

That sounds excellent!

I have 2 bluetooth modules of my own, but we've still got time to order some more. How many do you think we'll need?

I've put wifi modules in our simplebot kits in place of the long USB cable, and I have about 4 spare at the moment that could be used on sumo bots. They are the same ones that @ajfisher was playing with so known to work with Johnny-Five. It'll be interesting to see how we go with so many bluetooth/wifi modules in a confined space.

Cool. I think 10 working sumo bots will be safe. I might have to grab one of these Wi-Fi modules off you to learn how they work. Talk to you later on where/when. On Jul 17, 2014 9:43 AM, "Anna Gerber" notifications@github.com wrote:

Check out the SimpleBot repo readme for a really fast way to get that Wi-Fi module working.

Just to let you know that after some experimentation tonight I've discovered that Grove cables (i.e. JST PH connectors on one end and regular 2.54mm pitch sockets on the other) are perfect for connecting those wifi modules, and neater than using an xbee breakout board. We have half a dozen or so of them that we can add to the simplebot kits.

Example: http://www.seeedstudio.com/depot/Grove-4-pin-Female-Jumper-to-Grove-4-pin-Conversion-Cable-5-PCs-per-PAck-p-1020.html?cPath=98_106_57

ajfisher commented 10 years ago

Neat - so you just used the individual sockets onto the 4 pins you need on the WiFi module then the other ends into breadboard to connect to?

AnnaGerber commented 10 years ago

Ah actually we're now using 2 pin JST PH connectors on the modules. @nog3 misread the datasheet so we were connecting 1-4 instead of 1&2 and 5&6 :)

But 2-pin JSH PH connectors are even easier to find than Grove cables: very commonly used for batteries e.g. from RF hobby stores and also available from SEEED: http://www.seeedstudio.com/depot/JST-2-Pin-power-connector-p-649.html?cPath=98_106_57

Can you post a photo? Not quite visualising it (far too late a night last night!!)

The JST PH connectors are 2mm pitch and go on the pins on the wifi module. It's also possible to get 10-pin JST plugs if the other pins needed to be connected. These cables have tinned ends to plug directly into the breadboard. wifimodule

Example with longer connector: wifimodule2

ajfisher commented 10 years ago

Ha - cool. Never knew that JST connectors were 2mm spacing. I have loads of these laying about.
