DARPA looking for a shuttle replacement

With the shuttle retired and funding for the Orion killed back in 2009, the US is currently without a way to get people into space or a relatively cheap way to get payloads into orbit.

DARPA has apparently decided not to wait for NASA, and has called for commercial companies to propose candidates for their XS-1 space plane.

DARPA’s key technical goals for the XS-1 include flying 10 times in 10 days, flying to Mach 10+ at least once and launching a representative small payload to orbit. The program also seeks to reduce the cost of access to space for 3,000- to 5,000-pound payloads to less than $5 million per flight.

Having this capability will fill a hole in LEO access left by NASA policy and budget constraints.

Plenty of clean base electrical power can be had…

A pair of MIT trained nuclear scientists founded Transatomic Power.  They have developed a molten salt reactor that uses the nuclear waste produced by fresh waster reactors for fuel.

Instead of wasting all that potential energy, we could being using to power these inherently safer reactors that don’t produce weapons grade nuclear material as a by product.

As Dr. Pournelle said, “…with what we spent in Iraq we could build nuclear power plants and space solar power satellites and tell the Arabs to drink their oil.”

The plants developed by Transatomic Power could deliver a steady supply of carbon free electricity that could power our industrial base, expanded use of electric cars, and provide light and heat to millions of Americans cheaply, reliably, and safely.

 

Springtime for nerds

It’s spring and the mind of the geek turns to new hardware releases.

The iWatch is still the hot rumor, but I wouldn’t expect that to even be announced until September.  That is when Apple will, probably, announce the iPhone 6, and iOS 8.
I’ve seen rumors that Apple will include a range of fitness tracking options in the much debated iWatch.  If they do, then they have a chance to pounce on the market hole created by FitBit recalling their Force device.   This also puts a lot of pressure of FitBit to come up with a Force replacement (with a functional wrist band) PDQ.  If they wait too long, and the iWatch rumors get stronger, they will loose market share to Apple’s vaporware.
On the Amazon front, they have discounted their Kindle devices.  Given that they had razor thin margins at best at the retail price, I’m taking the discounting as a sign they want to dump inventory.  Flushing the channels of the current inventory in preparation for new model Kindles in the pipeline. I expect them to announce these well in advance of Apple’s big announcement in September.  Big retail sale days for consumer electronics include Graduation and Father’s Day (Dad loves his gadgets).  If they can make those dates, that would make up for the loss from discounting the current Kindles.   They count on the downstream sales on those devices anyway.
For the Android fans out there, take heart.  The Google I/O show is slated for June.  The rumor mill is expecting the next flavor of Android to come out as well as some new hardware.  A new Nexus and some more wearables to go with Google Glass are expected.

Nifty gadget

Today’s gadget is brought to you by the phrase, “Simple is Good.”

The modern geek has lots of gear, and there are still plenty of wires and cables.

Power cables, data cables, audio cables, and the list just goes on.

Wire Ties are great for organizing, but not optimized for things like keeping your ear buds cables from forming the bundle of knots it wants to form. OK, they do a good job, but it is a pain to clip them loose every time you want to use them.

So every modern geek needs a roll of Velcro wire ties.

You can get a hundred of these ties for under $8 on Amazon. Free two day shipping if you are a Prime Member.

For smaller bits of cable, like ear buds, Micro USB, or Lighting cables, I cut the ties in half. I find them easier to put on and off at that length.

So go forth and tame the snake pits of cables that exist in your home theater setup, your monitors, and that pocket in your gear bag where you keep the umptyfratz cables you carry around because they could be useful.

Fitbit Force

I broke down and entered the wearable market. Specifically, I replace my analog watch with a Fitbit Force.
The Force is a wrist mounted wearable that tracks the following:
Steps taken
distance walked/ran
calories burned
Flights of Stairs climbed
Active minutes
Sleep time/activity

It actually does that reasonably well. The Force can display most of that data using a OLED display, unlike the older Fitbit Flex wrist based wearable monitor. I like the immediate feedback right on the device. It reminds me when I’m sitting down too much. Getting up and walking around on a frequent/irregular basis actually helps me with my focus. The Force measures all of this using accelerometers and an air pressure monitor.

The Force will also display the time, but that is one of the two major downsides to the design. To find out the time, Fitbit has recreated that genuine early 1980s experience oh having to press a button on your digital watch in order to find out what time it is.

I’ll get to the other major design flaw later. First I want to cover more of the good points.

The Force syncs with my iPhone over Bluetooth. The Fitbit app then allows me to review the data collected in more detail and over periods of time (day, week, month). I can also log other items, including hydration input.

I can also sync my Force with my Windows 7 desktop, but I have to use the Fitbit custom Bluetooth USB dongle to do so. If I wanted to sync to my Macbook, I have to use the Fitbit custom Bluetooth USB dongle, despite the MacBook having Bluetooth 4.0 built in. Thus sayith Fitbit support, which is a PITA.

On the plus side, the desktop view is a web based app, which gives you everything the mobile app does, but bigger, which is good.

The second major design flaw is the crappy wrist band. I have fairly large wrists, so I’m wearing the Large version of the Force. I’ve found that the “latch” on the wrist band will pop loose when I put on or take off a jacket or long sleeved pullover shirt. The bloody thing will also pop loose if I flex my wrist the wrong way. There are very long threads on the Fitbit forums about this problem. People have lost multiple Force devices (many of which Fitbit has replaced, at $130 retail each), and Fitbits response so far has been to post a video on how to properly insert the slots into the tabs, which is the poor design of the wristband latch. User feedback has been better, including the suggestion of adding an O-Ring over the latch.

Overall I’m happy with the device. The geek portion functions well and gives me data to crunch, which makes me happy. The whole crappy wristband thing is a disappointment, but one you can work around as long as you are aware of it.

Serious though. Wristband design is a pretty mature technology. Somebody at Fitbit who valued form way over function green lighted this Charlie Fox of a design. A decision that has cost them a lot of customer good will. The question is what will Fitbit due in order to get that customer good will back?

Update: Fitbit has stopped selling the Force and issued a recall.  The reason given was the skin rash some users were getting from it.  The crappy wristband design probably didn’t help.  Since Fitbit has dropped this product and will not longer provide firmare updates or other support, I put it to return mine for the full retail value.  Fitbit claims to be working on  new tracker.  I posted the following to the Fitbit user forums:

With all the complaints about the Force wristband, there was an underlying theme of the issue being so frustrating because the Force was the best fitness tracker on the market. The users loved it, except for the bloody thing wanting to jump off the user’s wrist every time they took a jacket off.

I’m sure the Force replacement will be an even better fitness tracker, and have the ability to show messages and phone notification from your phone that the Force will now never have.

However, if it uses the same consumer hostile wristband, I certainly won’t be buying one. That move would certainly alienate the Force customers who love their Force but hate with deep passion the low quality wristband that is integral to the device.

Rocket City Rednecks

I discovered this show by reading one of Travis Talyor’s non-fiction books, A New American Space Plan.   While this post is about the TV show, pick up this book as well.  It’s a well laid out case of why American should be serious about getting into space again and how to do it.

Also take the time to watch the show, Rocket City Rednecks, either by streaming or on optical disk.   This show is about five self-identified Rednecks from Huntsville, AL, two of which are actual rocket scientists from NASA who actually build working gear.  Really cool gear that works.  OK, it works most of the time, but even when they fail, they learn from their mistakes so then can do it better the next time.  That is really one of the important lessons.  It’s OK to fail, as long as you learn from it.   Most of the gear is built in Travis’ father’s garage.   Charles Travis is a retired NASA machinist who worked on the Apollo program, and one of the five Rednecks who star in the show.

I’ve watched about a third of the first season so far, and they have built some really nifty gear so far.  These include a still in order to build a moonshine fueled rocket, the actual rocket, a balloon based observation platform, a working submarine, a radio telescope array using 18″ satellite dishes, under vehicle armor capable of withstanding an IED blast (they drove the pickup truck away afterwards), and a working “Iron Man” suit, that had armor capable of  stopping 9mm handgun rounds, lifting over 100 pounds with a single arm and fired rockets!

Just to add to the overall coolness of this, most of their projects are done over a single weekend with a budget of about $1000.  Keep in mind that three of these Rednecks are current or former NASA employees.  The two active ones have eight advanced degrees in science between them (Travis has five post-graduate degrees.  For those of you who know me, yes, that is one more than Amy currently has).  Rog (Rednect #4) doesn’t have any advanced degrees, but he does have a genius level IQ, and Michael (Travis’ nephew) is mechanically inclined and studying to be a machinist.   Still, if you know basic work working, basic welding, how to solder two wire together, and some basic programming, you and your friends could try some of this stuff.

Which is kinda the whole idea of the show.  To get kids off the XBox and out there building go carts, rockets, radio sets and other cool gear.

This is the kind of show my dad would have loved.  He was 22 year veteran of the Army Corps of Engineers, and would have been out teaching kids how to to build the things the Rednecks are building.

Windows 8.1 blotware

I’m not surprised by the amount of bloatware Microsoft is including in its “free” Windows 8.1 update.

I’m sad, but not surprised.
