NEW $10 Raspberry Pi Zero Wireless

http://www.raspberrypi.org/products/pi-zero-wireless/

It should be available at MicroCenter at the end of the week:

The new RPi0 Wireless adds the same wireless chip that the RPi3 uses, adding the following features to the RPi0:

  • 802.11 b/g/n wireless LAN
  • Bluetooth 4.1
  • Bluetooth Low Energy (BLE)

I want to up my Pi game. Guess I’ll put that on my growing list.

I went by MicroCenter today, no RPi0w’s yet.

I am planning on getting a few of the new Pi Zero boards soon. I need to build several environmental monitoring packages to monitor vent temperature, airflow and humidity of two different HVAC units and two temperature sensors in the room monitoring the hot and cold side of the server room. Planning on building a homebrew monitoring solution to email and text if anything goes out of range before we have another meltdown if both HVAC systems stop working at the same time. Would be nice to have logged data for graphs to see what the trends are. I have several simpler setups I would like to also build for wiring closets and my home gameroom and shop.

Shawn, you might take a look at this $149 package from AcuRite:

They have arduino & pi with wifi and one with 4G. Does alot of what you mentioned off the shelf to speed things up

Airflow is pretty easy. You need a couple transducers though. After that transfer to static then velocity fpm to then area.

Wonder if anyone has printed nozzles for airflow measurement yet. Smaller ones should be doable, although surface roughness could do odd things to the Reynolds number.

That resonator circuit can be modeled in Microwave Office, aka AWR, now owned by National Instruments (yup, LabVIEW crew). I have the evaluation software on my machine, but I would have to beg for another eval extension to pull it out again.

A few other interesting observations about the resonator: Note the vias dotting around the periphery of the resonator and the entire ground plane. Note the row of capacitors between the ground plane and ELPIDA part. Wall o caps! And finally, notice the smooth trace. Now I would argue that I’m not sure that was necessary, but they did it and they can if they want to.

At the frequencies in question, the length of trace is no longer considered lumped. In other words, there is a distribution of voltages across the trace as the signal propagates down it because it is switching that fast (or sine-ing to be more to the point). I worked in a lab where such analog traces were testing and reference designs such as this was created. Power levels, noise figures, CMRRs and analog quantities of much craziness are computed and measured using VNAs, spectrum analyzers, and if the lab manager was super sharp-NI PXI based equipment. This is where guys who speak no english probe around on boards with capacitive probes and bridges and watch smith’s charts while computing impedances and reactances in real time.

Meanwhile, there are a few of these titans of analog lurking amongst the membership of DMS (not I, I am but a mere mortal). Nevertheless, pretty cool that pi board.

Who has these, anyone yet?

Canakit has them instock as of noon March 2, 2017.
Adafruit is out of stock.
MicroCenter doesn’t have them yet.

Thanks. Ordered one…

I went by MicroCenter again today, still no RPi0w’s.

Store manager said maybe Friday, but he didn’t have a definitive answer on when or how many.

If it goes like the Zero did when it was announced, it’ll take the Raspberry Pi Foundation months to get production up to speed…

Somewhere in the blizzard of stories yesterday, I read that production of the RPi0w will be in the 10,000’s/week instead of the 1000’s/week of the RPi0 at launch.

That’s great news!

now… I need to figure out a project for it… :smiley:

3E8Tech Purchasing Department just placed an order, so I hear…lol…

Something about a spin off of the DMS Raman, but maybe more interferometer-like and maybe less molecular weighty… prolly good for things like measuring Ra on, dunno, engine rebuild surfaces…

to tell the truth i have no idea where they come up with this stuff… :slight_smile:

oh, and I hear they like to cut folks in who want to get invovled in such a production targeting enterprise…

its just that i can never seem to remember the website address… oh yeah 3e8tech.com! …thats it, im sure of it!

I went by MicroCenter again this morning, still no RPi0w’s.

Crap! I want a few of these. Hopefully Microcenter won’t do a “Limit 1” like they did on the zeros.

Thanks for keeping us posted old pard.
