What’s in my cart?

Whenever I buy things on eBay, I tend to buy in waves, ordering a few things at a time. I was looking to get some new tweezers since I’ve been working with SMD components recently and wanted one with larger grips on the component. I ended up picking up four things in total last night.


tweezers

I have two tools for picking up components. One is a needle nose pliers and the other is a tweezers with sharp pointy ends (cannot compute plural dilemma with “pliers” and “tweezers” :/). I find them both difficult to use when soldering small SMD components so I found this type of tweezers that has a better size and form for handling those small components. I hope that it’ll make SMD soldering a little more pleasant.


minibMy Canon point-and-shoot camera had pretty budget packaging. It didn’t include a data cable so I’ve been borrowing one all this time. I decided to finally get one for dedicating to the camera. You can’t go wrong for $0.99!


microusbI decided to also pick up a new cable for my phone. I don’t know about you, but I hate those USB cables that come with phones nowadays that are thing, have glossy ends, and no tension/strain support. The one that came with my Samsung phone stopped working so I stripped it and started using it for powering projects through via USB power. I have a couple other USB cables that I can use with my phone, though one is too long (for my Logitech mouse) and the other is a bit too short (came with a USB battery, I think). This one looks like it will be just right at 1 meter and I like the grippy ends.


ledsAnd here’s the relevant segue! I did a little tinkering with my Light Show project and showed off a little show snippet that I posted on Instagram. In that one, I was playing around with my new 74HC595 Shift Register boards that allow some PWM control using the Output Enable pins. I’ve never used these WS2812B LEDs before because I’m cheap and have been using “dumb” 5mm LEDs for the Light Shows up to now. The plan is to replace the LEDs on the “towers” of the current light show with these new WS2812 LEDs.

With the attention back on the Light Show, I also want to do more experimenting with the fountain pumps. For starters, I will be swapping out the current 5v power supply with a 9v power supply. The pumps are rated at 6v so we’ll see what happens. I also want to work on a better nozzle design. I believe I was getting somewhere with the secondary nozzle design on the holiday light show, so for the next try I will make the openings slightly bigger and see where that takes me. With these changes, I don’t expect to rush into an actual choreographed show as I have in the past. The focus will be on one thing at a time. Stay tuned!
