Pi zero WIFI....

rew

I've designed a board which plugs onto a raspberry pi zero to provide WIFI through an ESP8266 module on the serial port of the Raspberry pi.

 

Now you may say: Why not just use an USB-wifi dongle? Those are cheap and work out-of-the-box! You're right. But in some cases that's not the best solution: When you are space-constrained and need exactly ONE usb device, not having to use a HUB pays off. imageimage

I have not yet soldered on the connectors in these pictures, to facilitate other configurations should that turn out to be practical.

 

So...

 

If you think this is useful, If you have some programming skills, If you have a use for this.....

I have the following offer: At the cost of the components (EUR 2.50 for the ESP, EUR 1.00 for the PCB+ rest) and shipping (max EUR 5.25) I can send you one. The deal is that you'll try to make the wifi part usefull....

 

Of course, developing the software is probably more convenient on a "bigger" pi.

 

Should something essential be hooked up wrong. We'll respin the board and get you a new version. No charge. The main reason that I'm not giving the hardware away for free initially is that I don't want people to say: oh, it's free, lets get it, I'll decide later if I need it/can help and then of course nothing happens. By asking for a little bit of money I force people to think about it and scare away the freeloaders. Also, the offer applies "as long as supplies last", i.e. whenever I think there is enough activity...

    Some dis-jointed Musings about WiFi for  RaspPi-Zero and Arduino.

    1.

    For Arduino there is the Sparkfun ESP8266 WiFi (arduino-compatible) Shield. Servo (paper) Magazine has article concerning it in their Aug 2016 issue.

    2.

    For those who might just use a WiFi Dongle instead of this beautiful new shield (by RW), it appears to me that you might (?) Not need a USB Hub. That being said: If your s/w App and RaspPi O/S are Stable, then just use the WiFi Dongle. IDK you will need any more USB Ports? Of course you would need a USB-A-(full-size)-female-TO-USB-A-(full-size)-female Adapter. But fear not, You can make one from a DEAD MoBO ( PC Motherboard). I take my Dremel Tool and cut-out those stacked USB Ports off the MoBo. Then I wire(solder) the "+, -, data+, data-" leads on the bottom of the now cut Mobo piece. A cheap solution w/ recycling implications. I am so "Tight" w/ $$, that I squeak when I walk.

    Nice recycling ...

     

    You are right about the need for a hub for most purposes.

    I maybe going "Rogue" or "Off the (indian) Reservation" here but, I offer two recipes. B/C my usually comments are not very useful. (a) Ever have those Instant Ramen Noodles? If you have extra Seasoning Packets leftover, Mix contents into Sour Cream. You have a Dip. Spoiler Alert: these Ramen noodles are NOT healthy b/c they are already Fried. You can eat then like reconstituted Potato Chips (Pringles Brand in USA). (b) If you Do Not have an Outdoor Grill (I have two Gas, one Charcoal) AAR par-boil Rack(s) of Whole Ribs. Stand them on-end in a Large Pot. After the Meat recedes from the bone, apply BBQ sauce and place in Oven. BUT do not throw away the liquid in the Pot. Skim off the Fat. Then add Watercress , season w/ Salt , then you have Watercress Soup.BTW My Charcoal Grill acts as a Smoker, so I do not do (b) anymore, So it is a Case of: Do As I Say! Not As I Do!
