Chip programmer with a twist

I am working on 1000 projects all the time.  You may already know that of me.  This one will be a fun adventure.  I’ve started by shrimping.it this is a site where they show you how to build a bare-bones Arduino.  I went and ordered the part for 4 kits via the electronics seller http://www.taydaelectronics.com/ it was under $30 for all the parts I needed.  I did not get boards as I plan to design my own at a later phase. Shrimp + SPI to 8 pin chip  Here’s the shrimp built with an 8 pin chip holder where it can be used to program the little chip.  This is an Atmel ATTiny 85 ready to be programmed.

Now the hard part.  Let’s say I want to program a lot of these little chips.  Wouldn’t it be nice if the Arduino held in memory all the code and capabilities to program the chip without an attached USB link to a computer?  That’s goal #2.

Here is an ATTiny 85 running code that was pushed through the Arduino in the traditional manner (Goal #1).  What I like about the Tiny line of chips is there is little to no supporting hardware required to have them run.  This makes them a lot of fun for all kinds of little builds.  They will even run off three or 4 AAA batteries and for quite some time.

Engineering Roundtable – Audio Spectrum Analysis and Fire!

In today’s edition of “Engineering Roundtable,” SparkFun Engineer Chris Taylor guides you through the use of a microcontroller to perform audio spectrum analysis. He explains the basics of working with the audio spectrum and ultimately links up his project with a propane torch. Why? Well…why not? Check it out:

Current electric highway

(puns are fun) This is a google map showing the current supercharging stations. From this alone, you should be able to get to any destination within 100 Miles of any of these locations and do so without any range anxiety. If your final destination has charging options then you can be comfortable within 200 miles of any of these locations. If you look into public charging stations you can probably cross the country in any direction. By 2015 the Tesla stations should enable cross-country trips with ease. I am going to get to know California then the country.

If you are listening Tesla – Phoenix next; I have travel plans and a place to stay all ready to execute.

The Tesla Model S charge port, juice er up fella!

Charge It!A mini fact:  So far the average charge time for the car has been about 2 hours for a normal day to work and back.  If I drive more conservatively someday perhaps that time will come down (unlikely anytime soon).  In the photo, the surface that looks like a button is indeed one.  When you push this the little flap, that is part of the running lights, pops open.  Push the plug into the car and the green ring will light up.  Pulsing slowly or quickly depending upon the current battery level.  Press the button again to pull out the plug.  All of that will only work if you have the key fob with you.  I tried to remove the plug when the key fob was in the house and it would not unlock/come out.  Also, the car can detect the plug is in and will not let you drive off.  Good thing for those (not yet fully) caffeinated early morning departures.  I am not keen to look at the PG&E bill but will do so shortly to see how we are doing in that regard.

On a slightly different note today all driving about has been electric.  A gas-free day today.  I’ll maybe start tracking the car and bike usage (all cars and bikes).  When the cars are used to do anything that counts and if the bikes are used to do anything useful other than exercise that will count.  In a gas-free world, I’d take my electric bike to work while the rest of the day’s outings would be in the Tesla.  A fully electric day.  Half and half would be we use 1 gas and one electric.  Full gas would be we used no electric.  There will be the odd day we don’t go any place at all.  I should probably track this on a Google sheet.

Lastly will be doing the daily cash costs of gas vs electric from the simple fueling only perspective.  I am certain if I use all the gas items from the CC bills over the last year and the electric bills there should be some way to see how much money shifted to electric and if there are any savings at this level.  That’s data collection so someday soon again.

Tesla Model S is here.

The Tesla Model S is a thrill to drive.  I love speed and acceleration so it is a good fit.  To say it has all the features of an electric car sells it short.  It has all the features of any car you’d ever really want.  It just happens to be electric.  A few posts will be here over time about the car and when there are interesting developments but otherwise expect the hardware and geekery that’s considered normal.

Today I drive the car to work for the first time.  My impression of the car, dark in the garage, fully charged, was one of latent power.  For an odd reason, I perceive it as asleep and not off.  Odd that I perceived anything of this nature in fact.

First hours of ownership, why not drive the coast for a while.

Hi ho hi ho.

Stock Bot to Arduino

The original StockBot was built on the Netduino platform.  I’ve been working on the code for the Arduino platform and have now assembled working code.  I can’t claim it is stable yet but it’s doing the job for now.

I am using the Ethernet Arduino.  As I explore a number of things all the time, I have also made a shield for the Arduino to see if this project could become a kit for others to build.  A little stuck on a source for Numitron tubes so I am trying to make the board generic enough to take a tube or a normal led display (still puzzling that through).

Let me clean up the code – I’ll take a hard look at it over the next month.  Maybe after the skis hit the slopes in Whistler I’ll have something to post and walk everyone through. Early December if you don’t ski or board.

What’s StockBot – here’s the beginning post

Here are the prototype boards I had made.  They have a nasty bug but I learned something (and could fix it so all is good).

Your passwords sux!

I have facebooked that LastPass is the tool everyone needs to be using.  I am not always clear as to why I select the tools that deserve your attention.  Every week I get some news and security tidbits from the below podcasts.  What I love about this particular source of information is that Steve Gibson provides ALL the details, dives deep and leaves no stones unturned.  I know this is the second post in a row about Steve’s stuff – but I really did get a Facebook message from a cousin today asking why he should trust LastPass with his passwords.

The short answer is that LastPass does not get your passwords (not exactly).  All that is sent to them is your encrypted stuff.

Most if not all of the password decryption runs in your browser – but it may look like it is on their site.  I am no longer 100% clear on this but myself I will have to re-listen to the first podcast below.

There are some password recovery items the paranoid should look into and disable (but think, know, trust, what you are doing when you do so).

Always Swim Up

Knowledge is the reset button

This post is about how knowledge and research can change your life.  A while back I made a simple internal pact with myself.  If I hit 200 LB I’ll just stop eating.  Funny thing is, that worked for three or more years.  I should mention there was a prior limit set at 195 LB.  Before that, I was not really watching.  Weight gain was depressing and all, but not getting in the way as far as I could tell (my doctor had been saying otherwise, but it fell on deaf ears).  When I started to mull over setting the limit to 205 LB I had to put my mental foot down and say no.  At that point, it came to starve a few extra hours a week to force the 200 LB limit into remaining valid.  That was probably going to be the rest of my days – fighting the 200 LB limit.  In fact, I had already resigned to it.

Diets for me are transient.  I’ll start on one once in awhile.  Never with true intent.  Never with passion.  Never with any successes.  Sure a few pounds at the start – yippie!

The 200 LB limit sat at the back of my brain taking up undeserved space while injecting the fear of getting set higher and higher over time.  I did not want another diet, I did not want to exercise a ton, I wanted to make sustainable healthy changes that put my weight on a downward slope, however slight, just point it down.

Then I learned something.  In one hour.  I was lead down the simple path of well-presented information to the knowledge that reset the way I look at everything.  I’ve recently “let my weight drop” and put it on that downward slope.  What a crazy sentence. It seems to imply I have control over the angle of the slope.  I do.  Today, for instance, I woke up to a 175 LB me. Nice!

What worked for me was simply adding quality knowledge about the human body to my brain. What is a protein, a fat, a carb, a sugar, a ketone?  What of these do I eat or process?  Knowing more about these; what simple changes can I make to effect the changes I have long desired?

It is difficult to find something that’s posted in/on the Internet without agenda.  I’ll try not to lie.  I want you to go out and learn how to learn.  How to filter the noise.  How to know when you don’t know.  I am not teaching these things, they are milestones on your way to finding the reset buttons in your life.

All I can share is what got me excited about learning to learn and to carve through the noise to find the pure notes of relevant research.

I listen to a security-related podcast every week.  By Steve Gibson.  Called “Security Now”.  If you are in IT or a geek like me you’ll find it wonderful.  Regardless, what happened out of the blue one day was; Steve did a health-related podcast about vitamin D.  Why?  I didn’t care, I got to listen to a very capable explainer explain all about vitamin D.  He consistently applies significant time and energy to each topic he presents on the podcast, this health episode was no different.  He even presented data he had collected from his own blood tests and experiments in sunbathing to collect vitamin D.

Fast forward a bit in time and there was another unexpected health-related podcast – this time Steve had been experimenting on himself as it pertained to diet.  As like any security related podcast he taught you the basics and built upon them (over two podcasts this time).  By the end, I knew I had started my next chapter in life.  I have since played the podcasts a few more times, bought and read two of the books Steve recommended, initiated simple changes in my daily food types, and lost 25 LB since May this year (4 months).  I have also since learned (as yet another chapter of life unfolds) that without quality data and research you are courting a mundane and manipulated life.

Question everything.  Question this blog post.  Research and return.  Question more.

 


 

New proposed TLD .pinkbunny

A new top-level domain (TLD) is being proposed to  B’ecause’ I CAN as a safe alternative to existing domain namespace.  The “.pinkbunny” domain will be aimed at those organizations requiring a high level of trust and security of their websites, such as kids with pink bunnies, those who may have lost a pink bunny and other critical infrastructure sites that deal with pink bunnies.
The proposal is that organizations successfully registering a site within the “.pinkbunny” domain space would need to undergo a thorough background check and also adhere to a number of strict security requirements such as photographic proof of said pink bunny and regular visits to the vet for checkups to ensure no virus infections.  Any sites not adhering to the security policies would be disconnected.  B(ecause) I CAN is currently reviewing submissions for new TLDs and is expected to publish its results over the coming weeks.

Lots of LEDS – now I get it!

This is the page that allowed me my “Eureka” moment on how to drive a large number of outputs from a very few number of pins.  If you ever wished you could have 10 or a 100 more output pins – the shift register chips are ones to consider.  I won’t blabber on just follow the link watch the video and you know where to start if it can be applied to your own effort.
