Compass Coffee

Compass Coffee

Compass was my first planned coffee stop for the day.  The location I visited was just a few bus stops from the Dolcezza.  It is a single-story brick building packed to the gills with coffee products, seating, and what appears to be the compass coffee roasting operation.

I ordered a small drip coffee, which was made with their cardinal blend, and a saag-paneer filled pastry, similar to a bao.  The pastry dough was sweet, and the sag-paneer was spicy and bizarre, but in the best way.  The coffee was smoky and sweet, a little acidic but not very fruity.  The coffee was served in a paper cup.

Roasting operation

I sat at a bar in front of their coffee roasters.  Like slipstream, light was provided mainly by numerous skylights and windows rather than with artificial lighting.  This, combined with the brick, gives the place a warm glow.  The place was pretty packed, with a long line when I arrived.  But there was plenty of space inside, and I think pretty much anyone who wanted a seat got one.

Sitting area

As you can see in the photo, they have pretty much every kind of cafe chair, ranging from various heights of 4-legged metal stools, to orange and white metal chairs.  The wood was mostly light colored pine and veneer, which was complemented by the white paint and tile.  The somewhat high ceiling and skylights give it an airy, clean, and open feeling.  this feeling conflicts somewhat with the general cramped mess and busyness of the floorplan.

The unassuming entrance

The CCC lacks the usual signage out front, but once you get inside, it is clear that it is a coffee shop.  They seem to serve intelligentsia coffee, but they also sell retail heart coffee.  As one would expect, the coffee is good. The coffee was balanced, with a smoky aftertaste.  It was served in an hourglass shaped diner mug, like the ones that Diesel sold before switching to intelligentsia-ware.

This shop is long!

The interior of the shop is long.  The grey bulkhead that comes out of the ceiling, the rail, and the long coffee bar all help make it seem even longer, emphasizing a far away vanishing point.  Their logo is three cups over two bars, which is similar to the flag of the District of Columbia.  Definitely clever.

On the left side, there are small four legged stools mixed with creamsicle chairs- white on the outside, orange on the seat.  These seats face each other over low spool tables.  In the front of the shop there is a bar at the window, and two very expensive looking tables with matching benches.  These feature a dark wood tabletops, metal frames and narrow benches.  It was a surprisingly comfortable spot to sip my coffee and read my book.

Peregrine Coffee

Peregrine next to NOT Peregrine (La Pain Quotidien)

Peregrine Coffee was the first stop on my coffee tour.  It seemed easy to get to form the Hirshhorn and it would be my only stop out on the east side of DC.  I arrived at about 4:00, drenched in sweat from my two-block walk over from the East Market stop on the Blue Line.  Say what you will about the heat on the west coast, but at least it is a dry heat!

This location is located right next to a non-peregrine cafe.  I was almost lured into buying coffee from them but the brew-o-matic and lack of coffee menu made me think twice, and check outside.  Sure enough, Peregrine was right next door.

Since it was about 90 degrees and humid, I opted for a smaller espresso instead of my usual small black coffee (the real standard for judging a coffee place).  I also ordered a ham and cheese pastry.

The pastry did not inspire any real confidence in me, with its single roll of ham and sparse cheese, but I devoured it anyway since I was hungry.  It was decent-edible but not a reason to come back.  Eventually my espresso was up (after a mix up that almost landed me with a macchiato).

The coffee on the other hand, was short- by that I mean it was a single shot of espresso.  One unusual thing I learned is that in DC, espresso is normally a single shot instead of the doubles you find in Boston and LA or SF.  Overall I was happy with the coffee.  It as fruity and the acid was fairly balanced.  They clearly have some idea of what they are doing over there with their machine and their counterculture coffee (they also have a house peregrine brand).  It was served in a standard white saucer/espresso cup/spoon, along side what I assume was supposed to be sparkling mineral water in a libbey druatuff glass.  Unfortunately this turned out to be lukewarm water, which was trumped by the free ice water they were also serving.

Pear Eh Grin

The decor was cute, but not in a way that stands out.  It felt like it was new and nice, and organized.  Inviting, but not too exciting.  They did have a funny rendition of their name on the wall (pictured above).  There is interior and exterior seating available.  The inside consists of a small square of tables in the front (about 4 people/table), a bar for seating for three, and another line of tables going back to the back of the cafe, each seating two.  Next to the line of tables is the coffee bar, including a pastry case, espresso machine, and retail area.  This cafe (like the rest of the ones in DC) also boasts a restroom.  Outdoors there are five tables that can probably seat three people each.

Nice, clean, but not exciting

The tables and chairs were a light blonde wood, probably pine.  The outdoor furniture is metal painted that rustoleum-lawn-furniture-green.  The counter echos this theme with a light wood and glass construction, giving the whole place a friendly (but not enlightening) interior.

Baked and Wired

DCIM104GOPRO

Line for days!  If you want coffee, you can probably skip it

When I arrived at Baked and Wired, after a bus and a schlep down 30th street,  I was extremely unenthused to find a line out the door.  What I did not know was that Baked and Wired is one of “those places” where people queue outside in 85 degree heat to buy expensive and trendy pastries.  There is nothing wrong with that, but typically this is not my scene.  I typically prefer a spot where I can grab a quick cup of coffee and a seat and spend a few hours lost in a book, writing emails, or pretending to be productive in some other way.

The coffee bar, featuring finger

Once I was inside, I realized that it is actually that kind of place, or rather half the store is that kind of place.  There are actually two totally separate counters inside, one for coffee and one for baked goods, which form a delicious symbiosis.  From the bakery, I purchased a pistacio cupcake.  From the coffee bar, I bought a cup of coffee.

The coffee was acidic and a little fruity- a nice sharp note compared to the creamy sweetness of the cupcake.  And unlike most cupcakes, this one had little nut-nuggets in it to add a nice texture.  Together, the two of them made a lovely afternoon snack.  Alone, I think the coffee would have still been drinkable, but the cupcake certainly enhanced the experience.

Blurry, but you get the idea.  ft. finger

The decor could best be described as mixed.  The coffee bar area has no seating.  The bakery is standard contemporary-cute and displays cupcakes under glass beakers.  Down a few steps from the bakery, there is a massive shell-shaped couch that faces an american flag.

Bizzare

In the back, things get real weird.  Napinks are attached to napkins with baked and wired stickers in what must be a fire marshalls nightmare.  Somewhere under all the napkins, I am sure there is a wall with more napkins attached to it via stickers.  Each leaflet in the strata is marked with a thoughtful doodle or a few words.

La Colombe

DCIM104GOPRO

La Colombe!

La Colombe was (and is) my ultimate stop for coffee in D.C.  Ultimate in both senses of the word- final, as well as the best.  If you want to have the best coffee that I found in D.C., this is absolutely the place to go.  Sadly, I did a terrible job of getting photos of it, so you will have to bear with a mostly-words description.

La Colombe is decorated with sedate walnut stained wood, warm brick, and cool steel.  Everything else is black.  The lights are a slightly warm white, and are augmented (and overpowered) by a large skylight and by the windows.  The indirect light from is very warm since it is reflected off the reddish brick and wood surfaces.  The chairs and furniture appear to be site-specific and have matching stain and hardware across the store.  One notable feature is the black and brass features on the furniture- something I have not seen elsewhere.

The coffee was amazing.  I had something fruity from their workshop selection, and it was easily the best coffee I have had in at least a year- maybe more.  I described it in my notebook as “it smells and tastes of cherries.  It is acidic, fruity and clean”.  The coffee was served in a highly decorated mug, with blue and red floral and bird patterns.  The saucer had a matching bird and floral pattern.  Easily the coolest mug to date, aside from the old monkey-on-a-rocket-ship mugs from Diesel.  That is high praise coming from me!

The Best Coffee In Washington, D.C.


I visited D.C. over the weekend of the 9th to see an exhibit by one of my favorite artists- Robert Irwin.  After that I had a couple days to kill and I decided I would go on a coffee tour of the Capitol.  Based on recommendations from friends and cafes that I stumbled upon, I managed to visit 9 cafes in the D.C. area.  Below are my comments on each one.  Check out the map above for information on location and my recommendation.

Green Star = Best coffee in the area!

Green Pin = I visited and the coffee was good

Blue Pin = I visited a different branch and the coffee was good

Red Pin = I did not visit any of these cafes

Diamond = Would not recommend, better coffee nearby

My strategy was to hit all the outliers that had late closing times on my first “day” from about 3-8, and then sweep the Green/Orange line stops on my way to Union Station on day 2.  I decided to add peregrine to the list of day 1 locations so that I would have about 4 cafes on day one and 4 on day two- to even out the coffee intake.  The day one list was peregrine, filter (since foggy bottom was closed on the weekends, I ended up going to Dupont circle), Baked and Wired, and finally Northside Social, which was far away but had late hours.

Day two began, surprisingly, with Slipstream and Dolecezza, which I happened to run into on the way to Compass Coffee.  After Compass I hopped a bus down to Chinatown Coffee Co and finally La Colombe.

Nice Pictures of Electrophoresis Gels

Have you ever struggled to take a picture of a gel?  Probably not if you dropped a couple k on a gel documentation system.  But for those of us who to take photos of gels and keep our money, you might look like this:

Image

In this photo, I am trying to hold my gel illumination (a couple of LEDS) in one hand, and hold my amber filter, focus, and take a picture with my other hand.  In low light, my phone camera can’t focus either!  Thankfully, my camera can take voice commands, so I did manage to take a picture.  I have a Samsung galaxy note II, (at the time of writing, this is a recently released, top of the line phone) which has a fixed aperture and TINY sensor.  Here is an example of the quality it produces:

20130715_193243

This is barely usable, but maybe ok for just a quick note.  however, you really have to know where the bands are to see them.  For reference, that is 200ng of DNA.  Notice the greenish tint around the bands, and the lack of definition in the gel wells.

What you really need is a camera with manual focus, and a small piece of plastic.  You want manual focus, because no matter what you do, there won’t be a lot of light coming through the lens.  This makes it difficult for the camera to autofocus, which can be frustrating.  Manual focus lets you use your superior eyes and brain to focus.  Here is the device:

So there ya go.  Thats a UV (clear) filter with a piece of amber plastic in it.  I only bought the filter because I wanted it to be convenient to screw on and off.  Any plastic that is this color will work for blue light- there is no mystery there.  Here is what the world looks like through this lens:

Woah man, it's like instagram

Woah man, it’s like Instagram

Now lets take another look at that gel.  In fact, I will put both here so you can swap between them:

This slideshow requires JavaScript.

Which one looks better?  Definitely the one with the filter.  It has a few things going for it:

  • No confusing green tint around the illuminated area.  This is confusing, since the bands are also green
  • No high-ISO noise in the non illuminated area.  More even illumination.
  • Slightly better focused image (Ok, I am to blame, I did not focus very well)

It was also WAY easier to take the picture.  Just point, focus, and click!  If I had a better illuminator, I wouldn’t even have to hold the LEDS!  There is also a difference in pixel count, but that is mostly irrelevant, for the quality of image.  Commercial gel docs use sensors that are much under 2 MP.  By pixels, my phone camera should be 4x better!

What really matters more is the size of the sensor.  As a rule, larger sensors are better, but I don’t need to explain that- you can read Ken Rockwell’s excellent posts on the megapixel myth and look at comparisons at high isos here.  Use the drop downs to look at side-by side comparisons of different cameras at high-ISO (what happens in low light, like with a gel).  Check out the below, which compares the canon rebel xs (10 MP, 419 square mm square APS-C sensor, 185 on ebay, WITH lens), the canon 510 HS (12.1 MP, 28 square mm sensor, on ebay, 12.1 MP) and the Sony CyberShot DSC HX20V (18.2 MP, 28 square mm sensor, 260 on ebay, 18.2 MP).  These are buy it now prices.

Winner is the XS 1000, as you can see the difference in the dark colors!

Winner is the XS 1000, as you can see the difference in the dark colors!

This is a picture of a test swatch, with very similar colors next to each other.  As you can see, the cheapest camera, with the smallest number of megapixels, but the largest sensor has the best color differentiation, and low noise at a relatively high ISO 1600 (for reference, 400 ISO is the most common speed for “general use”).  The XS 1000 also has manual focus!  My conclusion is that if you want to take a picture of a gel, use an older, cheaper APS-C sensor camera, and get a filter for it.  You will thank yourself for it later when you have nice pictures.

My Chorded Keyboard Vision

I am building a one handed chorded keyboard, which is exactly what it sounds like.  It is a keyboard, but instead of using the qwerty layout, it uses chords of keys as input.

The main reason I want to build a one handed chorded keyboard is because it would be convenient.  A few of the advantages I see are that it will be smaller, cheaper, and will reduce the amount of devices that I use to interact with my computer.

Lets look at a typical interaction with my laptop, which is my primary computer (my other computer is my phone).  I have 6 input devices to choose from.  They are:

  • built-in trackpad
  • built-in nub mouse
  • built in nub mouse keys
  • built in trackpad mouse keys
  • tray-style keyboard
  • logitech mouse (wireless)

my laptop interface

This is already looking bad.  First off, there is a triple redundancy in the pointer category.  second, the nub is useless as a normal pointer, because its left button is underneath my left thumb when my left hand is on the home row.  the nub mouse buttons are also extra-super-hard to push, so you don’t accidentally push them with your thumb.  The trackpad has a similar problem in that it is crammed in there near the spacebar, and sometimes it gets pressed by my thumb and does weird stuff.  To add insult to injury, the keys are huge dust collectors, and can jam if they get a big enough piece of stuff in there, which happens frequently with little pieces of 26 gauge wire insulation which is just big enough to slip into the gaps.

On the other hand, the logitech mouse is a joy to use, provided you have a large flat surface to work on.  However, I prefer the logitech trackball mouse (m570), because you don’t need to move it at all and it is larger and more comfortable for my hand.  That said, the build quality of the m570 is sub par, and it feels kind of cheap-o.

So lets look at a pretty common workflow for solidworks.  I start out left hand on the keyboard, right hand on the mouse.  Thats great for clicking around, but eventually I need to enter a number.  Then the dreaded top-row numbers come into play.  lets say I need to enter “23.43”.  The “.” button is way over by my right hand, with the arrow keys, enter, and backspace.  So in order to enter something, I have to move my left hand across my body to those keys, which my left hand does not normally type on.  So instead, I end up moving my right hand to the keyboard, and then back to the mouse, and back and forth, and there are numkeys, and shifts and lot of moving.  it is particularly annoying because I need to do this over and over again in my workflow.

Now lets think about writing code.  Alpha characters are pretty awesome on the querty layout, but { } [ ] | : ; ” ‘ ( ) = + -* all require a lot of right-hand movement, and a lot of them involve holding down shift.  While this has become second nature to me now, I would gladly swap a few alpha characters for those keys.  Or even have a querty[]{};:'” keyboard, with more keys!  QUERTY was designed for typists on typewriters, not computers.

crazy busy desk

Crazy busy desk.  This is a real picture of what my desk looks like.

This is my final whiney paragraph for this post, but take a look at this picture.  This is a real, in-use picture of my desk.  Look how many keyboards are on this desk.  There are THREE.  two laptops, and an external keyboard because the netbook kb is too small, and too far away, but there is barely room for the external keyboard because of all the crap!  To mouse on either of these machines is also a pain, and it means I have my wrist unsupported on the right, or I have to reach over a tangle of wires on the left.  On top of it all, I was barely even using the computers- they were mainly just for datasheets or running scripts.

With a chorded keyboard, I will be able to put my laptop veeeery far away and control everything through a chorded keyboard and mouse combo.  Even if the keyboard is utterly crappy, and can only type 2 wpm, it will be plenty good for looking at datasheets, or goggling something while I am at the bench.

Inspiring People: Cellfyre, Andreas Sturm, and Chris Templeman

Every now and then I run into or chat with people who are really excited about DIYBIO, and it is really these people who get me excited about what I do at BOSSLAB.  I just wanted to give a shutout to a few people who have recently been awesome:

Cellfyre is from Oregon, and intends to start a DIYBIO group out there!  According to her twitter, “Everybody is handed a coupon for scientific knowledge at birth. Many have forgotten to redeem theirs. To create awareness I advocate #DIYBio, #STEM, and #PLoS“.  She came down to BOSSLAB (last week? hard to tell with finals going on) and we talked about what it is like to run a DIYBIO lab, sourcing equipment, and getting people excited.  You can (and should) check out here twitter here!  If you are in Oregon, tweet at her!

Andreas Sturm is a student who works somewhere in Europe (I am unsure of where), and is very ambitious in the development of hardware.  His do it yourself bio-hardware blog should be up soon- I will definitely share it here once it is up!  Since bio-engineering of any kind is very taboo- to the point of being illegal- he has to work closely with his university to do even transformations!  But he still persists in being curious and hacking up useful tools.

Chris Templeman is an engineer and presumably owns Templeman Automation in Somerville.  It turns out he was the driving force behind the sub $200 (if i recall correctly) PCR machine that was released by cofactor bio a while back.  He is smart, excited about biology, so keep an eye out for him.  He is also behind a pretty sweet multitouch computing table kickstarter, here.

Downloads fixed…Empty blog post fixed…

The past couple weeks have been intense, school wise and I have been ignoring cool projects/fixing the downloads section.  I thought I had a pretty solid post on setting up your own streaming webcam site too…until I discovered it had all been mysteriously deleted.  oops!  I took that down, but in the process I found out the wordpress has a sense of humor.  When I compared an older revision of the post against itself, I got these gems:

Oh no!

Am I trapped in The Matrix? 1999?  you decide!

Anyways, I will get that post fixed up soonish, and I will get my recent bio exploits posted soonish, and something about a laser projector.

All coming soon.  ish.
