Silly Job Title: Master Planner. I am the Master Planner!

In this video we unbox our TI-36X Pro scientific calculator from Texas Instruments.

The books I mention are TI-36X Pro Scientific Calculator Practice Examples and Calculus on the TI-36X Pro Calculator. These books are low quality (lots of errors and omissions) but they’re still useful.

The manual is here: TI-36X-PRO-Guidebook_EN.pdf.

The QR code on the insert goes here: https://education.ti.com/en/select-country/eguides

There’s more information on the Texas Instruments website: TI-36X Pro scientific calculator.

This is the box:

Silly Job Title: Charge Changer. I am the Charge Changer!

In this video we take a look at what has arrived in the mail from Amazon and AliExpress.

I mention in the video about the September 2026 edition of Silicon Chip magazine. I am reading Fundamentals of Solid State which you can purchase for AUD$40 on the Silicon Chip website from the bottom of this page. In the video I say that it dates back to 1979, but actually it dates back to 1984. Close enough! If you’re not into paywalled content they have some free downloads including The Internet – What’s In It For You?, When I Think Back 1, and When I Think Back 2.

The cheatsheet I mention is Periodic Table Advanced. I have a bunch of these QuickStudy cheatsheets.

The stuff from Amazon is:

The stuff from AliExpress is:

If you’re interested in the CH341A programmer you might like to learn how to mod it for low voltage.

The various current sources, voltage references, and transistors which arrived in the mail today were the purchases I made for the equipment we looked at from The Art of Electronics.

Update: there was some confusion when I made this video. I ordered the G2 model but when it arrived I couldn’t find any G2 branding on my device so I mistakenly thought I had been sent a G1 instead. In fact I had not. I did in fact receive a G2, it’s just that the G2 branding was very subtle and I missed it. The only indication seems to be a small “G2” on the back under the HP logo. Also I heard that the G2 model came with a USB-C connection, but that is wrong. My G2 has a USB-Micro connection, which I believe is standard.

CH341A Programmer

Update: there is conflicting information on the interwebs regarding the “fix” for this programmer. Some people say you should do it. Other people say it isn’t necessary. You decide!

Today I watched You Need This $10 Flash Programmer, But It Needs This Fix Before You Use It! and I picked up a few from AliExpress:

The video references thingino.com, which has firmware for cameras with Ingenic SoC.
