Basics to Transistor Selection

This is similar to how I select a transistor along with calculating the value of the Base Resistor required to place the transistor in saturation mode; ie a transistor in switching On/OFF mode. There is no point is creating my own video when this explains quite clearly the process.

A project is currently under way where I use this process, soon to be posted. Just a small heads up, the following small switching Transistor is my all time favorite, the S8050 NPN transistor :-)

Datasheet: S8050 Wing Shing Computer Components.

Backup FireFox Bookmarks and Favorite Extensions

Yes this seems to be an obvious option to find, but for years I have been using an extension called FEBE with FireFox which now no longer exists. So I finally used DuckGo to find the solution and here it is :-) So now when I change my hardware everything can easily be moved to the new machine. It's a shame I cannot export FireFox passwords but I guess that is a good thing, I also use Keepass2 which works just as good.

These extensions I cannot live without, especially the NoScript which is my all time favorite.

Todays Walk

It has been a while since I've done a walk, so my body wasn't feeling too comfortable half way through this loop but I'm sure it would get easier once I get back into some sort off  routine.

Aotearoa Bike Challenge Update

Failed goal, oh wow. Well it's Monday so lets get this Challenge up and running once more! Good thing to know when logging in this morning I have gained a few more badges :-)

Nice to see the Champion badge 1,000km recorded on this site :-)

New goal added, let's see if I can achieve this one!

Endomondo: Entered A New Challenge.

It has been a while since I've used Endomondo, especially over this wet winter period. Still nothing like getting re-motivated by joining a small challenge. Yes there is only 2 people in this challenge, myself and the challenge creator but I'm about to embark in creating my own challenges, especially targeted at local riders here in Wellington New Zealand.

First activity added to this challenge, it was a really wet ride as well I got totally drenched but still enjoyed the ride.

TimeLapse: Petone Foreshore Wellington, NZ

Not sure how this would turn out, but from looking at the results it seems OK. Even though everyone is going 4K these days, my computer still struggles to play this quality but I will keep on creating these rendered this way. 1080p50fps works for me right now.

TimeLapse: Wainuiomata Mary Crowther Park, LH, NZ

Really enjoying creating these, need a better way to manage my time while waiting the 48mins necessary to capture the 600 images. Leaving the camera unattended during capture is not an option.

TimeLapse: Wainuiomata Shopping Centre LH, NZ.

What happens outside our shopping centre at 9am on a Sunday morning in the middle of winter, not a lot.

Well on this mornings ride I had a small crash. I went up a driveway that had a triangular piece missing right in the middle of it. My front wheel lodged at this spot and instantly stopped the bike from progressing any further, which resulted in me flying over the handle bars. A quick check over the bike no visible damage and a test ride in the car park everything seemed good.

24kms later I wasn't feeling too good, so I stopped at this spot for a timelapse opportunity and check myself over. The graze on my legs I fixed up fine (I always carry a full 1st aid kit) but a few of my ribs was making it uncomfortable to ride, time go ride home.

With this timelapse I changed it up a little from 2sec intervals to 5sec intervals because I knew it was a boring place to capture LoL. The only problem with doing this it took 48mins to create this 24sec timelapse.

Installing Arduino IDE on Linux Mint 18.3

I have always had a problem installing this piece of software, you can download the archived file from here

Once unarchived you need to run the ./ in a terminal to create the desktop icon. Up to this point everything worked fine, until I plugged the USB cable from the computer to the Arduino board.

Loading up the example blink sketch, then sending it to the UNO resulted in an error message which unfortunately I cannot display because I have resolved the problem.

The problem was the UNO was not recognized on any port, so searching DuckGo I needed to find a BASH command that tells me what is connected to the usb ports. lsusb

which was actually pointless, all it told me was the UNO device
Bus 003 Device 006: ID 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter. I have no idea what to do with that information. So I played around with the Tools/Ports option in the IDE, choosing between /dev0/ttys4 try uploading, /dev/ttys0 try uploading again, same error. These were the only 2 options, until 5mins later, I looked again lo and behold a third option appeared,
/dev/ttyUSB. This has to be it, so tried uploading sketch again and bugger me a new error appeared LoL.

this time access denied. In fact this is something I remember from previous installations so back to DuckGo and find those BASH commands that allows me access.

sudo usermod -a -G dialout <your login name>

sudo chmod a+rw /dev/ttyUSB0

Not sure about the second line (didn't use it)  but all works perfectly now, so expect some Arduino Projects coming up very soon.

Twitch Experience: I Gots Me A Webcam

After 2 weeks on Twitch it was time to hook up a Webcam. I'm not sure how I would feel about this so the obvious thing to do was to quickly get my hands on a cheap webcam. $1.00 from Trademe, even though it was only 480p, perfect for what I want to do for now and in 3 days was on my doorstep.

You would think a simple device like this would work perfectly the moment you inserted the USB plug. Well yes, kind of. I got no indication/alert telling me a new hardware device has become available. So now what. Linux Software Manager opened to find a webcam program which resulted in a program called Cheese. Installed, ran it, it didn't acknowledge the presence of the webcam. For the next hour I was singing a different version of "Oh happy days" until I decided to do a reboot. It works, hallelujah! I see me on screen and go, geez who's this ugly bugga.

So I closed down Cheese, set up my Twitching environment, added a source using the webcam option, and it did not find the webcam. Here we go, another chorus of "Oh happy days" starts. So once again, started up Cheese and yes, once again Cheese didn't acknowledge the webcam. Well the obvious conclusion was, if you wish to use the webcam that day, do not close webcam window because if you do, you have to reboot the computer!

Using Cheese was fine, but I wanted to use the webcam without this program, it has issues and every time it crashes it was reboot time, so it was BASH time:-

ls -ltr /dev/video*

Use this to find what port Linux recognises the webcam

mplayer tv:// -tv driver=v4l2:width=640:height=480:device=/dev/video0 -fps 60

This will bring up a window showing, well your face :-)
It is this window I use as the source for OBS

Yes the quality is awful, and I intend on getting a real webcam like a Logitech 920 after watching and talking to Jade from Twitch.

TimeLapse: Wainuiomata Mall Playground, LH, NZ.

Another forgotten folder. I remember this moment. Had a flat tire so I put the Sony on the ground, started the timelapse. I need to work on my "what/where to record" to get that money shot.
