= Consensus Agenda =

== "Donations" of assorted items ==

Proposed new rule:

# Any donations of items that are placed at the space are subject to this rule. Except for section 5, this rule does not apply to transfers to one specific member who has agreed in advance to retrieve the items within 24 hours or items that are placed directly in member storage by mutual agreement with a member.
# Donations must be approved in advance by a director and must be accompanied by a full inventory. Any free standing item or container of items forming part of the donation must be clearly labeled with the date and the name of the donor.
# After members have had an opportunity to review the donated items, the donor is responsible for removing any unused items from the space.
# Before items are placed in the space, a $50 deposit must be paid. The deposit will be refunded in full if unused items from the donation are removed no later than 5 days after the initial placement at the space. Half of the deposit will be refunded if the items are removed no later than 10 days after. A larger deposit may be set by the board. The donor must agree to pay the full cost of disposing of the donated items if it exceeds the deposit.
# A member who agrees to retrieve items that are placed at the space by a donor and does not do so within 5 days of the initial placement may be fined up to two times the full cost of disposing the item, or three times the full cost if is not done within 10 days. Notwithstanding the cost of disposal, the fine may be up to $50.
# The board may waive the provisions of this rule for specific donations. It is the policy of the corporation that this rule will be strictly applied to all donations consisting of a large number of small, assorted items.

Comment (JL): I think the fine on the donor is onerous and logistically difficult. I'm proposing a ban on general donations to Hack Manhattan - person-to-person is acceptable. This is of course waiveable for certain things deemed useful (e.g. machine tools, a box of Arduino shields, paper bags of cash, etc).

Comment (MN): I object to the deposit. I feel that is simply too harsh and too difficult to be enforced consistently or evenly. I feel that director approval and full inventory should be enough to discourage people simply from blindly dropping stuff off to get rid of it. However, I do support the above ban on general donations. I feel that rule alone makes the deposit unnecessary.

=== Printed matter ===

* Printed matter—do we have enough flyers and business cards?
** We won't do flyers this time. Too expensive (20-25 cents), we would need too many, and the value is too low compared to a cheaper business card.
** We can't avoid some kind of printed matter. Everyone will ask for a card and will be too inefficient to explain that we don't have them.
* General business cards - maybe enough?
** We will print 1,000? (5-8 cents per card)
** Meryl - add URL to business cards! --[[User:Merylgreenblatt|Merylgreenblatt]] ([[User talk:Merylgreenblatt|talk]]) 00:54, 5 September 2014 (UTC)
** David Reeves - david@hackmanhattan.com - title? 'Director-at-Large' - Thanks! --[[User:DrReeves|DrReeves]] ([[User talk:DrReeves|talk]]) 21:15, 4 September 2014 (UTC)
** Justin Levinson - justin@hackmanhattan.com - title?
** Meryl - two things: I still have my HM cards, saying Intelligence Collector. I'm continuing to use these, but I'm also planning to include the pdf on the back of my next set of personal Vista Print cards; Guan, would you please create a Director-at-Large pdf for me that I can import? I want to order them soon. Thanks! --[[User:Merylgreenblatt|Merylgreenblatt]] ([[User talk:Merylgreenblatt|talk]]) 00:54, 5 September 2014 (UTC)
** Small batch business card are kind of expensive (10-20 cents per card). Maybe we only need personalized ones for the most important ones, and we can attach stickers to the back of generic cards.
** Cheapo online vendors are low quality and will project a terrible image. We've had Staples (fulfilled by Vistaprint) cards before, and they were printed on an inkjet that did not have black ink.
* Giant poster? Foam core? Meryl - can easily mount paper on foam core for stability --[[User:Merylgreenblatt|Merylgreenblatt]] ([[User talk:Merylgreenblatt|talk]]) 00:54, 5 September 2014 (UTC)
** How to mount to FACETRON6000 fabric
** It would be nice to have a big large poster that visitors can read when all HM members are busy talking to people.
** How big would it need to be? Ideally we would just a paper poster that we won't worry about getting destroyed. --[[User:Guan|Guan]] ([[User talk:Guan|talk]]) 21:08, 4 September 2014 (UTC)
* Stickers?
** Justin hates them. The people love them.
** 5-10 cents a piece
* Fresh inkpad for the stamp - several visitors have asked for a stamp in their hacker passports - might save on cards, especially if the QR code scans properly?
** Is [http://www.amazon.com/Avery-Carters-Stamp-Black-21381/dp/B00006IBQJ/ref=sr_1_1?ie=UTF8&qid=1409866024&sr=8-1&keywords=stamp+ink+pad&tag=hackmanh-20 this pad] ok? --[[User:Guan|Guan]] ([[User talk:Guan|talk]]) 21:27, 4 September 2014 (UTC)

Typewriter ASCII art

2014-06-06T07:52:01Z

Menager: /* Saturday morning */

2014 group project idea. The public facing page is [[FACETRON6000]].

= Idea =

A webcam takes a photo. A typewriter style printer renders it as ASCII art.

= Project management =

== FIGMENT submission ==

Guan and Meryl. Deadline April 15. FIGMENT is June 7-8, 2014.

Requirements:
* Copy
* Name

MG - I'm thinking the Public Project Description should be written as our marketing pitch. Here's what I drafted so far; needs some polishing, comments welcome:

FACETRON6000 prints your portrait in "ASCII art" on a typewriter. A camera takes your picture, shows you a preview, then lets you press a button and watch your picture "develop" from alphanumerical and symbolic characters. Take home a customized computer-generated photo!

Alternative:
Create and take home a genuine/your very own ASCII art self-portrait! FACETRON6000 takes your picture, shows you a preview, then lets you press a button and watch your picture "develop" from
alphanumerical and symbolic characters. Be the envy of your friends and family!

== Physical realization ==

Justin

Photo booth? Typewriters scattered across a desk? Help wanted!

* Most likely a single computer/display/webcam, controlling multiple typewriters
* Each typewriter would have an Arduino, connected through a USB hub
* A screen for white background
* Stupidly large button to take the shot?

== Image processing and ASCII conversion ==

Guan

[https://github.com/hackmanhattan/typewriter Git repository]

Physical sliders for contrast and such?

== Typewriters ==

Guan and Rob

We need more typewriters! Donations welcome. Newer Brother models, especially GX-6750, easier to work with and we can use the same kind of ribbon.

== Name ==

Idea categories:

* Machine/robot: FACETRON6000, TYPETRON6000, Pictobot 2015, BROWNFOX4000
* Descriptive: SelfieType, FaceType, Instypegram, QWERTYmatic, Clackstagram, Snapwriter
* Fun: Mavis Beacon's Photo Booth
* Pun: TArt (for Text Art), PhAArt (for Photo to ASCII Art)
* Name: Barbara, Tracy

== Outstanding questions ==

* Table?
* Will the box have walls, or just one side for a photo background?

= Components =

== Typewriter ==

* Teletype, teletypewriter, radioteletype
* Daisywheel or ball printer
* Modern typewriter with electronic buffer
* Printing (mainframe) terminals, eg DECwriter

[[File:Brother.jpg]]

A good option is [http://www.amazon.com/gp/product/B00004WFSC/ Brother GX-6750]. It's not as easy as using an actual daisy wheel printer. However, it's relatively cheap and available new from Amazon, including ribbon. Once we figure out how to hack it, we can potentially have many of them set up to print at the same time.

See [http://numist.net/post/2010/project-typewriter.html project typewriter] for an example of a Brother typewriter based teletype project.

The GX-6750 in the space currently has a breakout board that taps into the ribbon cable. Note that if the keyboard is not flat against the case when the typewriter starts up, it may raise an error. Solve this by pressing down the top two corners of the keyboard 20 seconds after the typewriter powers on.

Scan frequency is still 62.5 Hz, with 2 ms per line:

[[File:Brother-scope.jpg]]

== Imaging ==

A simple webcam should be fine.

We should do some image processing before passing to the ASCII art library. To save keystrokes, we could shoot people against a white background. We could also do edge detection, either [http://processing.org/examples/edgedetection.html directly in Processing] or with [https://github.com/atduskgreg/opencv-processing OpenCV].

[[File:Imageprocessing.jpg]]

This was done in Processing with OpenCV:

[[File:Typewriter-contrast.jpg|600px]]

== ASCII art libraries ==

* jp2a (C, JPEG only)
* aalib (C)
* [https://issues.sonatype.org/browse/OSSRH-3295 Native Java library]

For now, we've rolled our own in Java (for Processing). It divides the image into blocks corresponding to each ASCII character, takes the average brightness, then maps linearly into a fixed 22 character set stolen from jp2a.

= Screenshots =

[https://www.youtube.com/watch?v=Y1lXQWUGEC4 Video of a recent test]

[[File:Typewriter-dave.jpg|700px]]

= Operator instructions =

== Basic instructions ==

Boot into Ubuntu and doubleclick on FACETRON6000 on the desktop. That should launch Processing with our sketch. Click the Play button in Processing's toolbar.

Move the mouse cursor horizontally and vertically to adjust contrast and threshold inside the window. These are the two parameters we adjust to get a good image. The background should be white. Head shape and facial features should be visible.

Press p on the keyboard to print. Make sure you only press once, otherwise bad things can happen.

Before starting the print, the top of the paper must be aligned with the TOP of the clear plastic cover:

[[File:Typewriter-paper-adjustment.jpg|300px]]

It is probably a BAD idea to use the paper lock release lever on the typewriter because using it will make it hard to align the angle of the paper. Always keep it locked, and use the return key to advance paper. You can also use the round knob on the left side of the typewriter to advance/reverse paper, or the REV key (CODE-O).

Observe the printing and make sure nothing goes wrong. The paper should probably be further left than you think, to avoid the carriage catching on the paper. The big vertical line in the plastic (not the triangle) is a good approximate position for the left edge of the paper:

To stop printing:

# If it's a mechanical problem, for example paper getting stuck, turn off the typewriter, then hit the Stop button in Processing. Press the Stop button in Processing, unplug and plug the Arduino back in, turn on the typewriter, hit the Start button in Processing.
# If it's not a mechanical problem, for example if you're simply printing the wrong thing but there's nothing fundamentally wrong, hit the Stop button in Processing. Printing will stop after the current line is done. Advance/reverse paper to the appropriate position and start over.

== Troubleshooting ==

=== Start over ===

The Arduino MUST be powered on first (connected to a powered on laptop) before you turn on the typewriter.

If you want to power cycle the typewriter, make sure it's off for at least 10 seconds. The caps are very big.

If you power off the Arduino, and turn it back on, it will re-enumerate. You probably need to restart the Processing sketch (Stop button and then Play button).

Make sure the ground is connected if there are weird errors. It will often work without ground connected.

=== Typewriter connections ===

If you need to redo the connections from typewriter to Arduino:

The ribbon cable has 16 wires. If you are facing the typewriter, the pin farthest away from you is wire 1. Wires 1-8 are columns and pins 9-16 are wires.

Columns are numbered 0 to 7. Rows are numbered 0 to 7.

Wire 1 is column 0, wire 9 is row 0. Column 0 goes to digital 12, column 1 goes to digital 1, and so forth down to column 7 at digital 5.

Row 0 is digital 4, down to row 2 on digital 2. Then row 3 is on analog 5, down to row 7 on analog 1. Analog 0 on the Arduino is not used.

A thin black wire comes out from under the typewriter keyboard. It is connected to ground on Arduino.

We are using a Seeeduino, a red Arduino clone. It should be in 5V mode.

=== Linux devices ===

Near the top, the string variables serialDev and cameraDev specify the serial and camera devices to be used. The serial device is usually /dev/ttyUSB0, but if another Arduino or something else with a virtual serial port is plugged in, it may be different. It seems kind of random which camera device is /dev/video0 and which is /dev/video1. You may have to retry every time.

=== Image ===

For threshold, the full width of the window is mapped to a value between 0 and 255. For contrast, the height is mapped to 0 and 5. It may be necessary to alter these ranges. In the case of threshold, it might be to adjust within a smaller range for increased precision. This is done in the following lines:

<code>Imgproc.threshold(mask, mask, (int)Math.round(map(mouseX, 0, width, 0, 255)), 255, Imgproc.THRESH_BINARY);</code>

and

<code>opencv.contrast(map(mouseY, 0, height, 0, 5));</code>

For threshold, the relevant figures are the last two arguments of the <code>map</code> call, not the final 255 or the initial 0. For contrast, it's the last instances of 0 and 5.

== Ferries ==

We have reserved 5 tickets for Saturday and 5 for Sunday for the non-public ferries. They will be picked up by the first people going out on Saturday, at the FIGMENT desk outside the Staten Island (!) Ferry Terminal.

The non-public ferries on Saturday and Sunday depart at 7:00, 7:30, 8:15 and 9:00.

== Volunteers ==

=== Saturday morning ===

Meet at Hack Manhattan at 7:30am for 8:15am ferry.
