Description
Adafruit Feather M0 Express - Designed for CircuitPython - ATSAM#3403 We love all our Feathers equally, but this Feather is very special. It's our first Feather that is specifically designed for use with CircuitPython! CircuitPython is our beginner oriented flavor of MicroPython and as the name hints at, its a small but full featured version of the popular Python programming language specifically for use with circuitry and electronics. Please note, CircuitPython does not come preloaded. See the full guide linked
#3403We love all our Feathers equally, but this Feather is very special. It's our first Feather that is specifically designed for use with CircuitPython! CircuitPython is our beginner-oriented flavor of MicroPython - and as the name hints at, its a small but full-featured version of the popular Python programming language specifically for use with circuitry and electronics.
Please note, CircuitPython does not come preloaded. See the full guide linked below for instructions on installing it.
That doesn't mean you cant also use it with Arduino IDE! At the Feather M0's heart is an ATSAMD21G18 ARM Cortex M0+ processor, clocked at 48 MHz and at 3.3V logic, the same one used in the new Arduino Zero. This chip has a whopping 256K of FLASH (8x more than the Atmega328 or 32u4) and 32K of RAM (16x as much)! This chip comes with built in USB so it has USB-to-Serial program & debug capability built in with no need for an FTDI-like chip.
Here's some handy specs!
- Measures 2.0" x 0.9" x 0.28" (51mm x 23mm x 8mm) without headers soldered in
- Light as a (large?) feather - 5 grams
- ATSAMD21G18 @ 48MHz with 3.3V logic/power
- 256KB of FLASH + 32KB of RAM
- No EEPROM
- 32.768 KHz crystal for clock generation & RTC
- 3.3V regulator with 500mA peak current output
- USB native support, comes with USB bootloader and serial port debugging
- You also get tons of pins - 20 GPIO pins
- Hardware Serial, hardware I2C, hardware SPI support
- PWM outputs on all pins
- 6 x 12-bit analog inputs
- 1 x 10-bit analog ouput (DAC)
- Built in 100mA lipoly charger with charging status indicator LED
- Pin #13 red LED for general purpose blinking
- Power/enable pin
- 4 mounting holes
- Reset button
The Feather M0 Express uses the extra space left over to add a Mini NeoPixel, 2 MB SPI Flash storage and a little prototyping space. You can use the SPI Flash storage like a very tiny hard drive. When used in CircuitPython, the 2 MB flash acts as storage for all your scripts, libraries and files. When used in Arduino, you can read/write files to it, like a little datalogger or SD card, and then with our helper program, access the files over USB.
Easy reprogramming: the Feather M0 comes pre-loaded with the UF2 bootloader, which looks like a USB storage key. Simply drag firmware on to program, no special tools or drivers needed! It can be used to load up CircuitPython, PXT MakeCode or Arduino IDE (it is bossa-compatible)
Comes fully assembled and tested, with the UF2 USB bootloader. We also toss in some header so you can solder it in and plug into a solderless breadboard.
Lipoly battery and USB cable not included (but we do have lots of options in the shop if you'd like!)

You will find out how a selective private college evaluate and admit students
Format: Paperback
I'm a high school counselor and college advisor. Fifteen years ago when I started my college counseling position, I struggled to understand or explain to students and their parents how a selective private college evaluate and admit students. It was this book that helped me understand the essence of selective private college admissions. Compared to other dry theory books, this book tells the admissions practice as stories that are easy to read, understand, and associate with. I highly recommend this book to students, parents, and new counselors.

Who edited this mess?!?!?!?
Format: Kindle
This is a very interesting work of nonfiction. I found it intriguing and read it very quickly. I actually got invested in these students and their stories and their journey to get admitted to the college that was right for them. BUT, and this is a big but, this book is so poorly edited, it is disgraceful! If a person were reading this for research purposes, and it could be useful for just that, good luck to them. The dates are all over the place. At one point, the kids are being considered for the class of 2004, then it makes a reference to the current year as 2000, then it reverts back to 2004 for a long while, then it mentions how the kids--currently at their various chosen colleges--reacted to the events of 9/11/01. What the hell? It's very confusing. It makes it very difficult to keep things in context.

Abundant information but needs update
Format: Kindle
I struggled a little when try to decide how many star to give. It's an excellent book and very informative. It feels like I was not reading a college admission advisory book, which very often are dry and mechanical. It feels like reading stories of students and AOs, I got attached and involved emotionally, and really felt for them. But there were abundant information in the book, I was able to use the book to answer most my questions. If you need a list of YESs, Nos, Warnings..., then this is not the book for you. If you need to know what happens during admission process, then this is an excellent book for you. Based on the information in this book, I was able to extract my own conclusions.
The reason I hesitated if I should rate this book as a five stars book is how long ago it was written. A lot has changed. Many aspects stayed same, but many aspects changed. It will be misleading if this is the only guide book you are using. Wish everyone a great college application season.

An intimidating read
Format: Paperback
This is a scary book to read if you are anyone, but most especially a Parent of a college bound junior or senior. The writer, Jacques Steinberg, a NY Times Reporter writes beautifully and captures the college application process in an authentic way, without overdramatization. His style and sensibility reminds me of Jon Kraukeur. I was prinicipally struck by the heroic Sisyphean efforts of the admissions office and the immense gap between public school and private school admissions counseling at the high school level, a gap which is even greater today. This is also a very good description of Wesleyan University -- what it is not so good at, and this is no fault of the author who tries to make this point and the related one that follows , but the best approach for the applicant is to find a college where he and she can thrive and trust the process, the admissions folks are very dedicated to bringing in students who can add value and to whom they can add value -- more to the point when a good fit is made, all the effort and anxiety is well worthwhile to the school and the applicant. good luck and best wishes to all of you who are college bound.

A must read for anyone getting ready for college!
Format: Kindle
Very eye opening! I really got a feel for what the admissions officers go through. I really had no idea, i thought it was much more impersonal. My only complaint is that I wish along with the other students in which they chose to go into depth that they would have chosen an international student. I would have liked to have known how they were evaluated as compared to the American applicants. But still this book was not only helpful but interesting as a novel with personal stories you were interested in following.
