Silly Job Title: Master Planner

In this video I create some cables so I can attach my circuits to my roof aerial. I also announce the old book and new book for the upcoming teardowns which will be released in the next few days.

While doing this video I learned over on the EEVblog Electronics Community Forum that the specific RF cable connectors we are using in this project are Belling-Lee connectors.

There is going to be a break in Maxitronix 20in1 videos for a few days while I wait for my new Logitech BRIO webcam to arrive. Once that is here recording in the booth will resume.

In this video I mention the Silicon Chip magazine and Beginner’s Guide to Reading Schematics. Also the various new book teardowns I refer to are:

I also refer to MPLAB X IDE and MPLAB PICkit 4 In-Circuit Debugger.

The technology I mention in the beginning of the video is this:

The new monitor I refer to in the video is this UPERFECT 4K Monitor 15.6″ Portable Gaming Monitor UHD PC Screen USB C Monitor.

The cables I use in this project are these:

Man I had a lot of trouble figuring out what these things are called. I can tell you that they are not called F-Type, BNC, SMA, N-Type, or PL-259 connectors. In the I end I asked about this and learned these connectors are called Belling-Lee connectors, also known as IEC 169-2 Female/Male. But if you search for “IEC connector” (which these things are apparently sometimes called) you will only find the power adapters, not these aerial connectors.

Making Xbox cables

This morning I was fooling with cables for my Xbox. I want to make some breakout boards with controllers and front-panel buttons and LEDs that I can install in my bench and simply plug in when I’m working on a board.

I had a play with what I had in stock and built the cable you can see below. In the bottom of the frame is the Xbox controller connectors for two controllers, and in the top of the frame is my 10 pin JST PHD connector which I wired up just to make sure I had the right components and everything was working.

It works, but I used 22 AWG gauge wire where I probably want 24 or 26 AWG instead, so I ordered some of that on AliExpress.

I also swung by Digi-Key and stocked up on JST PHD connectors. On an Xbox motherboard (I’ve only checked v1.6 so far, I’m just getting started) you will find a 10 pin JST PHD connector for the front LEDs and power/eject buttons, two 12 pin JST PHD connectors for the controllers, and a 14 pin JST PHD connector for the DVD ROM. I got all such things:

And because I seriously lack restraint I purchased a shitload of every type of USB Type A Female connector I could find on AliExpress:

Also I’ve set up some storage so I can work on multiple OGXbox projects at the same time:

Power cables

I’ve made another batch of cables. These ones are power cables. For connecting my bench power supplies to breadboards.

I made two sets of banana plugs to DC male with inline switches:

And two sets of DC female to jumper pin:

And one set of DC female to DC male with inline switch:

Before I made these cables I figured out that it’s best to install the SPST switch into the positive wire.

My soldering started out pretty bad:

But I got better:

I tested both full sets:

Both green light:

Now I have a DC Power cable drawer:

Multi-meter cables

Made some cables. Male banana plug into male jumper wire. Got some of these and cut them. Made a pair of long ones and two pairs of short ones. This is so I can plug my multi-meters into my breadboards. Gonna do the same thing with some BNC attached coax so I can hook up my scope and with some female DuPont cables so I can plug into male pin headers.
