Newer Android car stereo

Posted: February 28, 2015 in Uncategorized

20150221_161932Due to a growing list of mechanical problems, it was time for my beloved Aurora to be recycled.  To replace it I bought a 2000 Nissan Altima, and with a new car comes a new stereo installation.  And a new installation means improvements, fixes and of course problems.

This time I added additional circuitry for input switching of four audio inputs, a universal volume control on the output, a usb port, bluetooth, and an auxiliary input.  The new circuitry is based around an arduino leonardo and stuffed inside the same project box from the first build, which was a tight fit. Next time I’ll definitely use a bigger box.

Runt bike

This is an old project that I’ve finally got around to writing about.  One day my friend came over to my house with this miniature “runt” bike.  He jokingly suggested putting a motor on it…..so I did!  Basically I welded on a platform on the back and attached a 34cc chainsaw engine.  I forget the gear ratio I used, but even with the smallest sprocket I could fit on the chainsaws clutch plate and the biggest sprocket I could fit on the wheel, it still wasn’t enough reduction.  I added a shaft between the engine and the wheel to add sprockets to further reduce the drive speed.  The original plastic wheels couldn’t be used, so I replaced them with pneumatic castor wheels.   The end result is a top speed of about 20 – 25 km/h which is kind of scary with such small wheels.  After it was finished, I really only drove it a few times, but I did manage to get a video of one of those times.

Log splitter

My dad hard at work.

My dad hard at work.

A while back, me and my dad made a log splitter.  Making a log splitter isn’t too challenging, all the parts required are readily available and the design is pretty simple. But we made this one as a bit of a ‘freecycle’ project by getting as many of the parts from a scrapyard and using materials we already had.  So if you think it looks like garbage, that’s because it kinda is.  In the end, the only parts we bought were the hydraulic valve, hoses, and a few fittings.  Fortunately all the parts we scrounged worked and are still working today.

Temperture controlled switch

Posted: December 10, 2012 in Uncategorized

This is a simple circuit I made a while ago. My dad needed something to turn on a fan in a heat exchanger and this is what I came up with. This circuit was used for about a year and a half for said purpose without any problems, other than explaining to my dad how to use it.  Basically, the circuit will turn on and off a relay based on two set points. Its simplicity also makes it useful for several other applications as well.  I used an lm335 temperature sensor as input.  The two pots set what temperature the relay will turn on and off at. Once the temperature goes above the high set point, the relay turns on and stays on until it drops below the low set point.  Simple and effective.

My '97 Aurora

My ’97 Aurora

I have always wanted a computer in my car.  I don’t know why, its a bit of overkill to simply play mp3s’, but I think my own geekiness is the driving force behind this.  I have wanted to do this for years now, but using a traditional pc, although possible, has several problems to overcome.  From piecing together hard to find components, cost, space, and most importantly, a user input method that can be used while driving without the risk of killing anyone.  Although, it was mostly the cost stopping me from doing this.  This all changed with the advent of the tablet.  Readily available, relatively cheap, all-in-one unit with a simple, low power input, and made for touch input.  Problems solved, now time to implement.  I’m not the first person to do this, but this is how I did it.

Hello world!

Posted: February 21, 2012 in Uncategorized

Sticking with the default title on this one seems appropriate, as it is my first blog.  Seeing as I’m not a real talkative person, I never thought I would ever write a blog.  But here I am…..writing a blog.  Although I don’t plan on using this as a typical blog,  but more as a personal website.  So the following posts will be more about things I’ve made or done, and less about opinionated rants, life stories, or whatever other people are doing on wordpress.  I won’t get into too much detail, but if anyone wants more info, just leave a comment or email me.
