Add Dimmer to ZY1010B 100W LED Driver

I will be working on 100W LED lights to help with lighting my videos. I bought this kit on eBay for about $30US:

I was planning to wire in a dimmer, like this guy did:

But alas, the LED driver I got did not have a trim potentiometer like the one in the video. However, on closer inspection, I found that the circuit board has a spot for one, there just isn't one there:

So I wired one in there, and it worked perfectly!

Here's a link to a potentiometer you can use for this:

And here's the video where I demonstrate how it works:

Stay tuned for a video where I put all of this together.

Save Money on CAD/USD Exchange Rates

A little known fact is that the banks that issue credit cards usually have an inflated foreign exchange rate. For many cards, like the Canadian Tire Options card, for example, that rate is 2.5% on top of the MasterCard exchange rate. So for us Canadians who do a lot of cross-border shopping, or shopping online in US dollars, that can add up.

Can you avoid it? Yes! Last year I found the Amazon Rewards Visa, only available to Canadians. Using this card, you will only be charged the Visa exchange rate, which you can check on Visa's website, and no more.

Apart from no foreign exchange fees, it does have other perks:
  • Free $20 gift card for signing up
  • 2% cash back on purchases
  • 1% cash back everywhere else (only applies to Canadian dollar transactions)
  • No annual fee
Once you earn $20 in cash back, it gets applied right to your card (your bill is decreased by $20).

To sign up, click on the link below. The application takes 5 minutes and you can start using it immediately on, before you even receive your card in the mail.

Make the purchases you've always been making for 2.5% less. We've found it worth it.

Stop Your Treadmill from Beeping

Are the beeps from your treadmill annoying? Want to run while the kids are in bed? Watch this video to see how to quiet your treadmill.

I'll show you four (well, technically five) different ways to do it:

1. Muffle the sound, if you just find it too loud.
2. Disable the sound entirely
3. Add a switch to turn the sound on and off
4. Add a volume knob

The 5th option, which is what I do in the video, combines 3 and 4. Options 1 and 2 require no special tools, but doing option 2 without a soldering iron is not recommended.

Here are wiring diagrams for the other options, with links to where you can buy what you need:

Here is a push on / push off (aka self-locking) switch:

Volume knob
You'll need a 20kΩ potentiometer (labelled as B20K), which you can buy here:

Volume knob with switch
For this you'll need a 10kΩ (or more) potentiometer with combined switch:

And finally, here is the video:

Leather band for RoadID Elite

In this video I'll show you how to make a leather band for the RoadID Elite to replace the silicone band that comes with it. I use these bracelets for my kids, and I've found that the silicone bands break after a while. I've gone through 4-5 bands now and I don't want to replace them anymore.

These bracelets can be bought at:

Note that you can buy the clasp and plate on their own if you plan on making your own leather band.

A leather trim piece can be bought on Amazon:
