Scallion Pancakes!

I really enjoyed living in San Francisco (albeit not as much as Ann Arbor, but that's a tale for a different blog), however, there was one aspect of life there that irked me day after day to the point of extreme agitation - I could not find any good scallion pancakes!

Attempts 2 and 3
For those of you who know what I'm talking about, I don't need to explain. For everyone else, suffice it to say that scallion pancakes are one of the most delicious dishes you can possibly eat, (when prepared properly).

Anyway, this week I decided to tackle the puzzle of learning to make them myself.

I found an article where the author talked about his experience attempting to make them on his own, trying out some recipes, then finally finding the real recipe while watching a cooking show, during which his mind was 'constantly being blown.' This sounded very promising.

After trying the recipe with unsatisfying results, I began experimenting. After about 8 iterations, I have landed on a passable recipe (read: delicious, although not necessarily the best I've ever had) for REAL scallion pancakes. (real to me is the flaky thin pancakes that are sometimes dough-y but super crispy on the outside with a lighter, sometimes spicy, but never normal tasting, soy sauce).

Here's what you need:

For the pancakes:
2+ cups regular flour
Boiling water
1+ cup vegetable oil (I used canola, but I plan to experiment with other types, perhaps palm)
1 bunch of scallions
2 eggs
Salt (do NOT overlook this last ingredient)
~30-40 minutes, although I believe the longer you let the dough sit the better, up to 24 hours (in the fridge)

For the sauce:
2 tablespoons soy sauce
1 tablespoon Chinkiang or rice wine vinegar (super important to use vinegar for this sauce)
1 tablespoon chopped scallions (optional)
1 teaspoon sugar
1/2 teaspoon grated fresh ginger
1 teaspoon duck sauce (optional)
1 teaspoon chili oil (optional)

The type of leavening used for scallion pancakes is not yeast or baking soda based, but rather achieved through lamination. What this means is to create the many flaky layers of the pancake, you basically create many layers of dough separated by oil.

Instructions:
-Boil ~2 cups of water
-Mix up your sauce ingredients to taste while you wait
-Pour the flour into a mixing bowl, then drizzle 3/4 cups boiling water into the bowl while stirring/food processing, until you get a very sticky, doughy texture. If there's too much flour, that's OK too
-Add the two raw eggs and mix well. Add/sprinkle flour as needed until you get a doughy, slightly sticky texture
-Work into a ball and let sit for a few minutes. If you can wait 30+ minutes, you will get better results. (Cover with a damp towel).
-Cut the ball into 4 equal segments. Each one will make a full pancake.
-Take a segment and roll it out into a ~8" in diameter circle. I use a floured surface to prevent the dough from sticking too much. The dough should be pretty dry at this point and very workable.
-Brush on a layer of oil (not a lot, just coat it), then sprinkle on salt and some chopped scallions
-Roll up like a fruit-roll-up // jelly roll, pretty tightly
-Now you're going to make a ball/circle of dough by coiling this snake around itself. Kind of like how a dog chases its tail. Take one end of the roll and have it be the center, then wrap the rest of the roll around itself, see photos.
-Roll this flat again into ~8" diameter pancake. Repeat the lamination with salt, oil, and scallions.
-Repeat the rolling & coiling, then flatten into a slightly smaller pancake. The wider it is, the thinner the end result. The thinner it is, the more dense your resulting pancake will be.
-Coat the bottom of a ~8" frying pan in oil, so that it is about 1/2 to 1 centimeter deep, and set it to medium-high heat (closer to medium)
-Slip the pancake in, and watch the edges until you see some golden-brown (about 2 minutes). You can peek at the bottom.
-Flip when you see the color you like, and let cook until the new side is golden-brown (about 1 minute this time).
-If you want an even texture, you can press down on the pancake or move it around in the pan. I prefer it the way you get it in restaurants- unevenly cooked.
-Remove from pan and eat!

LED Juggling Balls!

I learned to juggle for some reason when I was 13 and have (for some other weird reason reason) always thought it would be kind of cool to learn to do it with swords (or liquor bottles as a bartender for fun some night?).

While at Allgood over the weekend I thought it would be fun to brush up and try to improve a bit. I stopped by the vendor that was selling all the glow items. I had been wanting some for a while because I thought they'd be fun, could be used for other purposes (catch, poi), and would be small enough to carry around easily. So, I inquired about some light-up juggling balls. I was utterly shocked: THEY DIDN'T SELL ANY!


So, I made some. You can use any standard LED finger light bought on Amazon (or wherever) for about 50 cents a pop- and the light will last 60+ hours of continuous use.


Here are photos:

You can buy yours right here, and they will ship Priority (2-3 day).

How to upgrade the SSD in your Samsung Series 9 NP900X4C or NP900X3B/C Ultrabook

-----UPDATE------
If you'd like to see some photos of ultrabook internals (including what the mSata form factor looks like), see some of my other posts:

---------------------

I've had some folks ask me how to go about upgrading their storage capacity in their ultrabook.

The simplest answer is to buy a Dockbox, so you don't have to install anything to your machine or follow this guide (which is not necessarily for beginners :)

However, if you have some time, know-how, and $$, upgrading the SSD is definitely the best way to get more storage (at the fastest speed).

Here are the steps for doing it on the Samsung Series 9 (it will be pretty much the same for any ultrabook that uses the mSata form factor SSD. The Asus Zenbook Prime uses the Apple-style form factor).

1. Acquire the tools/supplies:
  • Download the clonezilla iso from here
  • get a 2+gB flash drive
  • follow this guide to make a bootable USB flash drive with the clonezilla file you downloaded
  • get an external drive or enclosure for your new SSD
  • get a new ssd
2. backup your existing drive
  • we need to boot to clonezilla. to do this, shut down your computer, and go to BIOS by turning it on and tapping f2 (or 'del' key in some cases) until you see a (likely) blue screen.
  • in BIOS, you will likely need to navigate to where you see 'boot options' or 'boot order' to enable USB boot and move it to the first in the list. The Samsung also requires you to DISABLE 'fast boot' (on another page) and I had to disable the SSD from the boot order list entirely by highlighting it and pressing shift+1 (shift key and the number 1)
  • now you can restart with the clonezilla USB stick in the machine, and it will boot to XBoot, where you can then select utilities->clonezilla. if you can't get to the XBoot screen, try using a different USB port or ensuring you have all the USB booting options enabled in BIOS. Also, make sure you created the USB stick properly ;)
  • clonezilla is pretty simple to use. after it loads, plug in your external drive and you will see some weird text when it 'sees' the drive. press enter and follow the on-screen instructions to make a backup image of your ssd to the external. you can choose beginner mode, and note you use the spacebar to select which drive is which (your external will be where you store the image, and the 'source drive' will be the 120gB Sandisk/Samsung SSD)
  • You can save yourself a few steps if instead of using an external drive you put your new SSD in an enclosure (effectively making it an external drive) and choosing the device->device option in clonezilla instead of device->image
3. install the new SSD & restore the image!
  • After clonezilla creates the image and saves it on your external, shut down the machine, unscrew the bottom panel and look at my photos for removing the insulation tape to get to the SSD. pop that sucker out and slap in your brand new one
  • Assemble, put the USB stick back in if you removed it, and this time do 'restore from image', obviously selecting the image file from your external as the source and the new SSD as the target
  • Undo whatever you changed in BIOS, remove the flash drive, and boot right back to where you left off, but with your new SSD!
If you have any questions, I'd be happy to answer them below!

How to Make a Collapsible LED Light-up Bo Staff for under $30

*****UPDATE: 3/5/2013******
I've dramatically improved the strength and sleekness of the design, and I also made the staff compatible with the $1 finger LEDs from Amazon.
See a new video here.

And you can now buy yours (DIY kit or full staff) directly on my site, techneesh!
**************************

I had about 15 people come up to me over the weekend (at Electric Forest // Rothbury) and ask me where I got my LED staff and how much I paid for it. It seems I'm not the only one frustrated that there's only really one LED staff on the market and it costs about $180!

So, here are instructions to make your own collapsible LED bo staff for about $25!

Building requires about 15 minutes time, a trip to Home Depot, and the custom translucent pieces I made (you can buy them with the button below and you will get them in 2-3 days).

1. Gather the following supplies:


(from top to bottom, left to right)
  • 2x 2' long 3/4" thick PVC pipe (pre-cut at Home Depot) - $1.39 ea/
  • 3x Glow Wands (can find at Sears, Home Depot, Amazon, etc) - $2-5 ea/
  • Electrical tape (whatever colors you prefer) - $3 ea/
  • Translucent endcaps, middle, & connectors - $19 - I made these myself, click the button below to buy them and I will ship out USPS priority (so you will get them in 2-3 days :)
2. Remove the LED + battery assembly from the glow wands, and secure the batteries in place with electrical tape:

3. Place the LED inside my translucent connector pieces and assemble them like this:

4. Wrap the PVC in whatever tape you'd like, or paint it whatever color(s) you wish:

5. Now pop in the endcaps and connect the two PVC pieces with the middle piece!


6. Congratulations! You now have a lightweight, collapsible, awesome-looking LED staff you made yourself for under $30 :)

Here's what it looks like in the dark:




For extra stability, you can use some extra electrical tape to secure the middle piece to the PVC. Most glow wand LED lights will last 60+ hours with continuous (and bright!) lighting :)

Please let me know what you think in the comments!

If you'd like me to make the entire staff for you, fill out this form and I'll ship it out within 48 hours!

LED Light Staff (3d Printed Bo Staff w/LEDs)

I've been looking for a new form of entertainment at music festivals (aside from the music) and decided Bojutsu might be fun. I came up with an idea for a 3d-printable, collapsible, reconfigurable led staff a couple weeks ago and have since printed some pieces for it.

Here is a prototype segment printed with PLA using the Makerbot Replicator.





UPDATE:

Toothbrush Holder Cup

My new apartment has a metal cupholder (with holes for old-school tiny toothbrushes) attached to the wall. I turned that into a usable toothbrush holder with this :)

Cat Litter Trap

Admittedly, I have been looking for excuses to put the Makerbot to work since I got it... nonetheless, I think the outcome justifies the effort for the most part~~

Useful objects for physical tinkering often are pretty easy to design - so far my experience really has been:
1. imagine a useful plastic component
2. model it in 10-30 mins in sketchup
3. print it
It's pretty awesome.

Anyway I've been in the process of moving into a new apt, and thought it would be nice to have a barrier from the cat litter box to the main floor. Here it is:




Looking forward to getting in a replacement (non-warped) build plate next week...
