Changed my Car Battery to Amaron (85D23L) battery after 13 months on my old battery (MF80D26L)
Amaron got good review on the web. Indian made. Let’s see how long will this last
Two previous battery died on me in 1 year. The last battery is 13 months old. Don’t want to get another incident of needing to jump start the car.
I’m reusing the old battery as storage for my solar project. Should have some more juice to last 1 more year
Lateral thinking is solving problems through an indirect and creative approach, using reasoning that is not immediately obvious and involving ideas that may not be obtainable by using only traditional step-by-step logic. The term was coined in 1967 by Edward de Bono.
According to de Bono, lateral thinking deliberately distances itself from standard perceptions of creativity as either “vertical” logic (the classic method for problem solving: working out the solution step-by-step from the given data) or “horizontal” imagination (having a thousand ideas but being unconcerned with the detailed implementation of them).
Discovered various means of purchasing online from oversea sources.
China is one BIG factory with millions of products.
Jack Ma did a great job building Alibaba and its various subsidiaries that is catering to different people
Intention is to have touch that is perpetually everlasting, “batteryless”, “maintenance free”
Experiment with a number of setup, with the following observation.
Tesla Torch is a variance of “Joules Thief”
Typical LED specs at 3.3V and can be lighted up at 3V
What “Joules Thief” does is using a amplifier circuit to boost Voltage up to 3V from a supply as low as 0.5V
It does this in pulses, meaning that the LED is actually blinking. OFF when voltage is low and ON when voltage is high.
The waveform resemble a square/sign wave.
Efficiency is not high – 60% typical.
A good site on “Joules Thief” is http://rustybolt.info/wordpress/
Tesla Torch is slightly different as it resemble a transformer on the coil portion.
Circuit flows through primary coil and LED is driven from induced current on secondary coil.
Efficiency may be higher, pending verification with oscilloscope.
Can’t measure voltage across LED with multimeter.
Tearing up a 1 cell LED torch and realized that it uses a silicon booster chip plus inductor, resistor and capacitor.
Its able to maintain consistent 3.3V output with input voltage as low as 0.5V. This can have efficiency as high as 80-90%
Lower the input voltage will have lower corresponding output current and transfer efficiency.
Efficiency aside. The concept of combining Super Capacitor with Hand Crank and booster circuit to light up a LED is commendable.
It extend the shelf-live and ease out operation expenses of a “Emergency Torch” eliminating the need to change battery, long term cost saving.
Super Capacitor is also “fast charging” compared to rechargeable battery. Allowing quick “light”
Good deployment for
Torch to have the following features.
Possible combination to achieve the desire outcome
The LAW of ATTRACTION, Mindfulness, Look at bright side of life….. there are various words and saying to this same thing. We are what we think we are. To train our mind to look out for beautiful things, touching events, the more we do it the better we’ll be at doing it.
Lets look out for nice things daily and share.
Shellshock is a bash vulnerability which has a bigger and wider footprint in the World Wide Web.
bash is pervasive is just about any variance of *nix.
To test for vulnerability.
$ env x='() { :;}; echo vulnerable' bash -c "echo this is a test"
have fun patching it up.
Was a nice session last night attending Celes annual get together. Met lots of interesting people with great personality.
Many inspired me with their determination and zest in life. Always seek and try out things that inspired you, things that you yourself felt worthwhile for you effort, that thing may potentially be what you’re searching for all this life, your dream job. No matter how remote the idea is. Give it a try.
WanXuan took the plunge and got a job in China. Chloe start dreaming big and work towards her goal as a life coach. Ngee Kee moved out of IT to start his own career coaching and consultation business.
What we need is the thought of giving and sharing, the idea of creating value for others, and not what the returns or rewards. When we bring enough value to others, others will bring value to us.
