Today I purchased 1,200 1W 1% metal film resistors for my lab. Particularly I wanted a bunch of disposable resistors which I can use once in a soldered circuit which I will throw in the junk box when I’m done with it. The main application for that at the moment is my Learning the Art of Electronics project which I’m working on. I only had space for twelve varieties and I got 100 of each type. Being 1W rather than the typical 1/4W makes them a little more forgiving on the bench in the case of overload and the 1% tolerances keep things nice and tight. The values I picked include:

In this video we take a look at what has arrived in the mail from AliExpress. Also a few things I picked up from the local hardware store: True Value Hardware.

I reorganized my cameras so that I have a wider view of the bench with my primary camera and a narrower view of the work area for my thermal cam. Also added an extra three zoom levels for the primary camera so I can focus in on the work area more or less as required.
In this video we take a look at what arrived in the mail. Mostly loot from AliExpress but also some USB hubs from Amazon.
In the video I mention Goo Gone. The stuff I use is the Original Goo Gone. It’s really great stuff! I mostly use it for removing sticker goo after I’ve peeled a sticker off something.
In this video I learn about “rivet nuts”. The ones I got are these ones. There’s a video on YouTube that will give you the idea about how these things work and are used.
I also mention about the 4017 integrated circuit which is a decade counter used in this project kit.
As promised I scanned the instructions on the cover of my “multitester” which is the analog voltmeter and ammeter I got:

I’m just about to kickoff with more note taking for my Learning the Art of Electronics project. Am aiming to have the video for the first lab ready for Tuesday.
You read that right. We made one of these before and I liked it so much that we are making one again! I get better at it this time round, I don’t make any of the mistakes I did last time.
The microcontroller in this clock is the STC15W404AS. It comes in the kit pre-programmed and I’ve not been able to find the software anywhere. Bummer. If you know where to get the software please do let me know!
The temperature controlled resistor is a 10K NTC thermistor which seems to be used for the room temperature function (which I don’t use and didn’t calibrate).
We use the Hakko CHP 3C-SA Precision Tweezers to hold our solder and poke about. At one point I drop a component lead offcut into the board and it shorted two resistors, so lucky I found it and pulled it out!
And that’s everything to know about this project!
Here’s a photo of the completed project installed next to the symbol keyboard on my desk:
