Nature vs Nurture

On occasion, I’ve been asked “What is I.Q.?” Is it nature, nurture, or some combination of the two? I make no claim knowing the answer to this question. But, I do think it’s both nature and nurture… mixed in with a bit good fortune.

People all have their own personal experiences. I like to think, that maybe having such a spread of years within my own family’s generation, contributed to my knowledge base. My generation, on my mother’s side of the family tree, spans more than 100 years. My eldest cousin was born in 1915, two years before the United States entered the first World War.

Having such a wide span of years, does have a few benefits. For instance, many of my family members were witness to events of historical significance. Some have even participated in, and can give a first-person account of, those events. I didn’t have to run to the library to read war stories, or how rough living through the Great Depression had been. I had a rich source of information… all I had to do was ask a close relative.

So, I can see how nurture can have a great impact on a person’s I.Q. Nature, admittedly, must also be a major player in the I.Q. debate.

 

OBDEleven

I’ve been an Audi enthusiast for many years. But, as any Audi guy knows, Audis can be problematic at times. That’s very true when it comes to clearing alarm codes on the more recent models. In my search, I’ve found a device that gives the end user the flexibility to clear those pesky alarm codes and even modify how your Audi is set up. That device is OBDEleven.

OBDEleven is awesome! It’s simple to use and is wi-fi based, easily connects to your laptop or smart phone… no cables required! No more going to the dealership to clear the yearly maintenance code or the occasional ‘check engine’ codes, saving you time and money. It gives you the ability to chart what your Audi is doing in real time. Checking misfires, torque, etc., it’s just a few clicks away. And you can store those charts on your smart phone for future playback. You have the option to send all sorts of data to anyone via email as well.

 

Aside from clearing ‘check engine’ codes,  OBDEleven enables the user to modify their Audi to fit their individual personalities. You may want your car to always have the running lights on when the ignition is on… no problem. Maybe you want to adjust the illumination of your inside lights or external lamps? Still, no problem. Utilizing the many options available on the OBDEleven app, you can change these settings and many more with just a few clicks.

 

One really nice feature that I like with this device is that you can check your lighting systems right from your laptop or smart phone. You can walk around your Audi while checking the blinkers, parking lights, etc. No need to have someone sitting inside the car to step on the brake pedal or to switch on the turn signal. It can all be done by clicking through the OBDEleven interface.

The device works on 1991 – 2018 models of Audi and VW. The Pro model unlocks several features that the regular model restricts. Cost is about $75 on Amazon at the time of this publication.

Machining journals

Question: What is a machining journal?

Answer: A machining journal is a daily log that records the many aspects of your workday in detail.

I’ve used machining journals since the beginning of my career as a machinist. I cannot tell you how many times those journals have come in handy. Sometimes you’re asked, ‘What did you work on three weeks ago on a Tuesday?’ Hell, sometimes I can’t remember what I had for breakfast this morning… and you’re asking me about three weeks ago? Out comes my journal. I can flip back to the day in question and accurately answer the question.

I’ve had bosses that approach me directly and ask about the material heat lot code on a specific material I machined sometime in the past. If they can give me a job number, I can give them the information they’ve requested. That’s important because, without the heat lot code, a job would have to be scrapped out. *Heat lot codes (explanation below) are directly tied to certification codes. They are the way we establish traceability of a part from the original material supplier of the material, through the manufacturing process, and on to the customer. The jobs could be inexpensive or high dollar value. Once I relay the material certification number to my boss, he can then request hard copy ‘certs’ from the vendor of the material… saving the job from being scrapped.

Keeping a machining journal is helpful in other ways as well. I’ve had instances when a supervisor would tell me to proceed with a job that I don’t feel comfortable with running. It could be a tolerance not being called out on a print or maybe there’s a question about the finish. In either case, writing an entry into your journal and requesting that the supervisor sign off on the entry, puts the supervisor in the position to defend his decision on proceeding with the job, should it become an issue at some later point in time.

Times have changed a bit since I began my machinist career. I no longer keep a journal but will document concerns, etc. with emails. Even verbal conversations that center around a decision by a supervisor, an engineer, or programmer, are put into an email format and sent to all parties concerned. That way, should a decision later become a point of contention, the email chain can be then be ressurrected to determine who said what.

 

 

*Traceability, through the use of heat/certification codes, are a requirement of nearly all high value parts supplied to the government, the aerospace industry, or other critical end customers. The reason for this requirement is that when a high value item fails, i.e. plane crash, etc. occurs, and the failure is traced back to a certain part… those high value items can then pulled out of service to be inspected by investigators for flaws.
