In this video I announce the new “Xin1” feature of the show. In the Xin1 feature we will work through the various Maxitronix electronic project labs that I own. We will be working through the following project kits, one after the other:

  • 10in1
  • 20in1 (actually branded “Sensor Robot 20”)
  • 30in1
  • 59in1 (actually branded “Electronic Digital Recording Laboratory”)
  • 60in1
  • 130in1
  • 200in1
  • 300in1
  • 500in1

That’s 1,309 projects to do!

As I mention in the video each time I start a new project kit I will do an introductory video to cover the front matter in the manual and to give an overview of the projects in the kit. Then I will make one video for every project in the kit. The project videos will be in this form:

  • Project introduction
  • Project construction (in the booth)
  • Demonstration and testing (on the bench)
  • Conclusion and review

And starting today the plan is to have a new video on the channel every day. So let’s see how I go with that! :)

Update 2024-05-10 jj5 – it turns out daily videos were way too ambitious. My new goal is three videos per week. Also standby for updates to the video format, I am thinking I will add a circuit simulation in LTspice and maybe an actual circuit build on a PCB designed in KiCad and manufactured by PCBWay.

If you’re interested in getting any of these Maxitronix kits yourself the best place I know to look is on eBay. Let me know if you find them somewhere else!

Update 2024-05-10 jj5 – I also found many of these kits are available at Altronics.

300in1 diodes

I made some notes about my 300in1 diodes. I have switching diodes, rectifier diodes, zener diodes, and germanium diodes. One thing to note is that germanium diodes are supposed to have a forward voltage of 300mV. One diode I thought was a germanium diode (it was clear with two black bands but no other markings) had a forward voltage of 600mV, I’m not sure what’s up with that, so I put it in my “unknown parts” drawer.

Full set! 1,283 projects to do…

I think this is just so super duper cool:

I call these, variously, 500in1, 300in1, 200in1, 130in1, 60in1, 30in1, and 10in1. Or, collectively, Xin1.
