RedPitaya case or housing options? - printing
The RedPitaya is a great looking instrument, but I'm afraid that I'll kill my new (expensive) device by stray voltage or ESD off my bench, within a few days.
Is it planned to make an optional "professional" case or similar to protect it?
Has anyone already created a 3D model so a printable case or housing could be made?
As a quick fix, I would:
use a piece of plain printer paper on the bench, underneath the Red Pitaya (it's typically more conductive than a typical plastic coating on the bench, but still not so cunductive as to short anything on the board bottom), and
more importantly, each time when approaching the bench, first touch the outside of one of the golden SMA jacks.
Probably any quick google search would answer the question but for the sake of completeness, I will answer this quesiton with what I found in my quick search.
Purchase Options

daily quote for each page with latex
I want create calendar planner from 1/1/2019 to 31/2/2019:
In Main.tex: I use \pgfcalendar{cal}{2019-01-01}{2019-02-31} to create pdf.
One page = one day
Now i want add each different quote to each day.
How write code in quote.tex and connect in Main.tex.
Thanks
\pgfcalendar{cal}{2019-01-01}{2019-02-31}
{%
\LARGE\bfseries
\pgfcalendarweekdayname{\pgfcalendarcurrentweekday},
\pgfcalendarcurrentday{}.

==========
I'd suggest setting up a daily quote in Excel with all the bells and whistles of formulas to extract the weekday, day, month and year from a date. I pulled some random quotes from the Internets to compile with each of the first 100 days...

Have figure appear close to the reference when ithe mages are included at the end of the document in latex
Hi I have a long document such as this wikipedia entry on Alice in wonderland below. I reference the figure on the rabbit in the first line but I import the figure at the very end of the document. I now want the figure to appear close to the reference in the pdf. Does any one have any suggestions? [h] does not work...
The White Rabbit (Figure \ref{fig:rabbit})
Chapter One – Down the Rabbit Hole: Alice is feeling bored and drowsy while
sitting on the riverbank with her older sister, who is reading a book with
no pictures or conversations. She then notices a White Rabbit wearing a
waistcoat and pocket watch, talking to itself as it runs past. She follows
it down a rabbit hole, but suddenly falls a long way to a curious hall with
many locked doors of all sizes. She finds a small key to a door too small
for her to fit through, but through it she sees an attractive garden. She
then discovers a bottle on a table labelled DRINK ME, the contents of which
cause her to shrink too small to reach the key, which she has left on the
table. She eats a cake with EAT ME written on it in currants as the chapter
closes.
Chapter Two – The Pool of Tears: Chapter Two opens with Alice growing to
such a tremendous size that her head hits the ceiling. Alice is unhappy and,
as she cries, her tears flood the hallway. After shrinking down again due to
a fan she had picked up, Alice swims through her own tears and meets a
Mouse, who is swimming as well. She tries to make small talk with him in
elementary French (thinking he may be a French mouse) but her opening gambit
Où est ma chatte? (Where is my cat?) offends the mouse and he tries to
escape her.
Chapter Three – The Caucus Race and a Long Tale: The sea of tears becomes
crowded with other animals and birds that have been swept away by the rising
waters. Alice and the other animals convene on the bank and the question
among them is how to get dry again. The Mouse gives them a very dry lecture
on William the Conqueror. A Dodo decides that the best thing to dry them off
would be a Caucus-Race, which consists of everyone running in a circle with
no clear winner. Alice eventually frightens all the animals away,
unwittingly, by talking about her (moderately ferocious) cat.
Chapter Four – The Rabbit Sends a Little Bill: The White Rabbit appears
again in search of the Duchess's gloves and fan. Mistaking her for his
maidservant, Mary Ann, he orders Alice to go into the house and retrieve
them, but once she gets inside she starts growing. The horrified Rabbit
orders his gardener, Bill the Lizard, to climb on the roof and go down the
chimney. Outside, Alice hears the voices of animals that have gathered to
gawk at her giant arm. The crowd hurls pebbles at her, which turn into
little cakes. Alice eats them, and they make her smaller again. Upon leaving
the house, she comes upon a puppy, with whom she plays for a while before
finding a mushroom with a hookah-smoking blue Caterpillar.
Chapter Five – Advice from a Caterpillar: The Caterpillar questions
Alice and she admits to her current identity crisis, compounded by her
inability to remember a poem. Before crawling away, the caterpillar tells
Alice that one side of the mushroom will make her taller and the other side
will make her shorter. She breaks off two pieces from the mushroom. One side
makes her shrink smaller than ever, while another causes her neck to grow
high into the trees, where a pigeon mistakes her for a serpent. With some
effort, Alice brings herself back to her normal height. She stumbles upon a
small estate and uses the mushroom to reach a more appropriate height.
The Cheshire Cat
Chapter Six – Pig and Pepper: A Fish-Footman has an invitation for the
Duchess of the house, which he delivers to a Frog-Footman. Alice observes
this transaction and, after a perplexing conversation with the frog, lets
herself into the house. The Duchess's Cook is throwing dishes and making a
soup that has too much pepper, which causes Alice, the Duchess, and her baby
(but not the cook or grinning Cheshire Cat) to sneeze violently. Alice is
given the baby by the Duchess and to her surprise, the baby turns into a
pig. The Cheshire Cat appears in a tree, directing her to the March Hare's
house. He disappears, but his grin remains behind to float on its own in the
air, prompting Alice to remark that she has often seen a cat without a grin
but never a grin without a cat.
Chapter Seven – A Mad Tea-Party: Alice becomes a guest at a mad tea party
along with the March Hare, the Hatter, and a very tired Dormouse who falls
asleep frequently, only to be violently woken up moments later by the March
Hare and the Hatter. The characters give Alice many riddles and stories,
including the famous Why is a raven like a writing desk?. The Hatter reveals
that they have tea all day because Time has punished him by eternally
standing
still at 6 pm (tea time). Alice becomes insulted and tired of being
bombarded with riddles and she leaves, claiming that it was the stupidest
tea party that she had ever been to. She makes her way back to the hallway
and, using the pieces of
mushroom, manages to get the key, unlock the door and enter the garden.

I'm afraid this is impossible to do in pure LaTeX. LaTeX's figure placements are restricted to 'here', 'top', 'bottom' and 'page'. None of these are sufficient for your case. 'h' from 'here' means close to where the figure is defined, not referenced. It is however possible to have your .tex file processed by some other tool to move the figure definition closer to the reference and then have the 'here' placement applied, or to not style the image as a float at all. Tools that can do this include awk and perl.
Zener Diode - What constitutes "Similar?"
I have very little experience with ECE in general and I am delving into using an Arduino for some small hobby type projects. I was following an online guide, and the person who wrote says that I need: "2 - 1N5227 or similar 3.6V biased zener diodes" I have read up a bit on Zener Diodes and now understand what they do and what their purpose is. I am not able to tell what he means by similar in this context though. I purchased a Diode Kit that includes 4 types of Zener Diodes. They all have different part numbers and voltages. The 4 I have are: 1N751 5.1V 1N4733 5.1V 1N4735 6.2V 1N4742 12V Would any of those be usable in this context or should I order the specific model he states? The guide being referenced is this, if it is helpful: http://www.instructables.com/id/RC-Transmitter-to-USB-Gamepad-Using-Arduino/ I really appreciate the time and assistance with this, this is a fun area to learn in!
In electronics and other engineering areas, similar refers to the property that stands out (in this case the voltage), in your case refers to looking for another zener diode whose voltage is similar to the example. As I see none of those diodes replaces the example.
Zener diodes has two parameters you need to match in the selection of a replacement (independently the manufacturer): The Zener voltage (Vz) and the diode power. For your application you will need a Zener diode of 3.6 V, and usually with 1/4 W to 1/2 W (depending the application power you will need) it will be enough. You need also to calculate the limiting resistor for the Zener diode. I recommend you to read the book of Albert Paul Malvino or similar to better understand. Regards.
Add data series to highlight cases on a box plot (Excel, SPSS or R)
first time user of this forum - guidance on how to provide enough information is very appreciated. I am trying to replicate the presentation of data used in the Medical education field. This will help improve the quality of examiners' marking of trainees in a Clinical Exam. What I would like to communicate will be similar to what is already communicated in the College of General Practitioners regarding one of their own exams, please see www.gp10.com.au/slides/thursday/slide29.pdf to help understand what it is I want to present. I have access to Excel, SPSS and R, so any help with any of these would be great. However as a first attempt I have used SPSS and created 3 variables: dummy variable, a "station score" and a "global rating score"(GRS). The "station score"(ST) is a value between 0 and 10 (non-integers) and is on the y-axis similar to the pdf presentation of "Candidate Final Marks". The x-axis is the "global rating scale", an integer from 1 to 6 and is represented in the pdf as the "Overall Performance Scale". When I use SPSS's boxplot I get a boxplot as depicted. . What I would like to do is overlay a single examiners own scoring of X number of examinees. So for one examiner (examiner A) provided the following marks: ST: 5.53,7.38,7.38,7.44,6.81 GRS: 3,4,4,5,3 (this is transposed into two columns). Whether it be SPSS, Excel or R how would I be able to overlay the box and whisker plots with the individual data points provided by the one examiner? This would help show the degree to which the examiners' marking styles are in concordance with the expected distribution of ST scores across GRS. Any help greatly appreciated! I like Excel graphics but I have found it very difficult to work with when choosing the examiners' data as a separate series - somehow the examiners' GRS scores do not line up nicely on the x-axis. I am very new to R but am also very interested in R, and would expend time to get a good result in R if a good result is viable. I understand JMP may be preferable for this type of thing but access to this may not be possible.
World of Warcraft (Lua) communication with Adafruit Gemma
I have an Adafruit (Gemma) / Arduino and a Neopixel LED ring that I would like to control from World of Warcraft in-game events. This part is soldered and working. Question: Is there any way to send communications between World of Warcraft and some sort of listener on the PC that can then in turn send messages over USB to the Arduino/Gemma device? My aim is to create an on-desk LED indicator e.g. if I'm a healer, then I want green/yellow/red light to represent the health of each raid/party member - so refreshes would be required at a high rate (0.5 / sec). Thanks for your feedback in advance and welcome any future possibilities with the soon to be released Warlords of Draenor.
Is there any way to send communications between World of Warcraft and some sort of listener on the PC Not directly via the WoW API. I came up with a way which I've never shared, because my usage broke Blizzard rules. But I haven't played in years, so here ya go. :) I used an addon to create a one pixel frame in the top-left of the WoW window. I manipulated the color of this pixel to send data to the outside world. The "listener" app can read this pixel with three Win32 calls: HWND hwnd = FindWindow(NULL, "World of Warcraft"); // find WoW window HDC hdc = GetDC(hwnd); // get the device context (graphics drawing abstraction) COLORREF color = GetPixel(hdc, 0,0); // read the pixel at x 0, y 0 I then interpreted the bits of the color like this: 4: sequence number 7: checksum: (sequence + key code + ctrl + alt + shift + win)/6 8: key code or ASCII character 1: 1: virtual key code, 0: ASCII 1: CTRL key pressed 1: ALT key pressed 1: SHIFT key pressed 2: WINDOWS key pressed The "sequence number" was just means of detecting that a new message had been posted to the pixel. The checksum was to prevent bogus reads when my special pixel was not active, like during loading screens. The rest was keystroke information. This allowed me to generate keystrokes from an addon. The entire watcher app is about 100 lines of C. Very simple. I wrote an in-game script editor and used this with "pixelbot" to automate things in game. Towards the end of my WoW life I had more fun coding for Wow than playing it, which is saying a lot, because it's a fun game. :) One upon a time I knew everything there was to know about WoW addon programming, but I'm several years out of date now. I'll see if I can dig up some pixelbot Lua code for, though. Anyway, you can adapt this scheme to send any messages you like. For instance: 4: sequence number 7: checksum (sequence + player number + LED color)/3 5: player number 2: LED color (0: green, 1: yellow, 2: red) 6: *reserved* As for speed, I never actually measured it, but it blows away your 0.5 second requirement. At most a few milliseconds of latency between writes and reads. that can then in turn send messages over USB to the Arduino/Gemma device? That's just writing to the serial port in the "watcher" app and using Arduino libraries for read from the serial port inside your device. I have source code for the "listener" app (pixel watcher) and for the WoW side stuff that writes message to the pixel. Let me know if you're interested and I'll help you out of band or dramatically increase the side of this post.
After some research, I did not found any built-in functionnality to signal/pipe/communicate with an external software. I believe it is due to the anti-bot blizzard policy. Actually you could do this with a memory watcher ( just like CheatEngine ), but there is chances you'll be banned for using this. The only thing you could do if you can't find anything, is to ask on official forum, and hope a technic-friendly blue poster will answer =) If you find anything, update your post, your idea is pretty interesting =)
There are only two ways to communicate with the game client without breaking the ToU: Saving variables between sessions. Meaning that you can have an addon read and write to its storage file but this requires you to either relog or to /reload the UI for this file to be written to and read from. In short this wouldn't be so viable. Have an addon use a tiny space on screen to write colors and use said colors to communicate with your external software by reading the pixels on screen. There are many ways to achieve the second suggestion. You only need to be able to write this addon for the game. Then write an external program to read pixels. Sending commands back to the game would require hotkeys or sending it in the chat window. Note that you are still limited to the API in-game that require hardware events. So for those you'd have to push a button or use the mouse to buypass.
