This turned up on hacker news today: JTAG ‘Hacking’ the Original Xbox in 2023 – Using Intel CPU JTAG to dump the secret bootrom in Microsoft’s original Xbox. There’s some info being collected on github: github.com/Necrosys/x86-JTAG-Information.
Need new UPS batteries
I have some old UPS devices which I’m going to have the batteries replaced in this week.
The one on the left is the OPTI-UPS Enhanced Series – ES-C 1KVA.
The one on the right is the PowerShield Defender 1600VA.
Learning the Art of Electronics: A Hands-On Lab Course 2ed
I have been sad for some time that Learning the Art of Electronics: A Hands-On Lab Course is out of print. Little did I know, they have been working on a second edition! The revised edition is due out in March 2025. Excellent news! I don’t usually pre-order books, but I will pre-order my copy of Learning the Art of Electronics: A Hands-On Lab Course 2ed. There’s more info on the book’s website: learningtheartofelectronics.com.

In this video we demo our third hands from AliExpress: Octopus Soldering Helping Hands Bench Vise Table Clamp with Flexible Arms Solder Iron Holder PCB Repair for TS101 TS100 PINE64.
I mention that I found a YouTube video which has a look at it: Octopus Hand supports Soldering for only 5$ – Turtle Review but like me they couldn’t figure out what the rubber and bolts on the base are for! If you know please let me know in the comments!

Low-Water Indicator | Project 17/20 | Maxitronix 20in1 | In The Lab With Jay Jay
This post is part of my video blog and you can find more information about this video over here.
You can support this channel on Patreon: patreon.com/JohnElliotV
In this video we do the 17th project from the Maxitronix Sensor Robot 20 (20in1) Electronics Project Lab Kit: Low-Water Indicator.
We use the Rigol MSO5074 Mixed Signal Oscilloscope to see the output of the astable multivibrator. In the video I make a mistake and attach the probe to the wrong pins.
We use the METCAL PS-900 Soldering Station to solder the wires I use for the banana plugs I attach to the touch sensor an voice sensor (microphone).
We use the UNI-T UTi260B Thermal Imager to look at the heat profile of the circuit. We see that the low resistances (470Ω and 1KΩ) get the warmest, but the higher resistances (e.g. 10KΩ) are also slightly visible.
We use the Fluke 17B+ Digital Multimeter to check the resistance of the touch sensor.
We use the Peak Electronic Design Atlas LCR45 LCR Meter to measure the resistance of the resistor we use in the LED attachment circuit. This extra circuit allows us to switch out the buzzer for an LED, which makes a lot less racket. The resistor it uses turned out to be 470Ω.
We use the Riden RD6006 Bench Power Supply to provide 9V for our test circuit. Usually I take a current reading to see how much power the circuit draws in its various states, but I forgot!
We use the Horusdy Soldering Station with Hot Air Gun for its hot air gun in order to shrink the heat shrink which we added to the banana plug cables we attached to our sensors.

Interlude #11: Playing with WeAct Studio Epaper Modules on ESP32-C3 MCU | In The Lab With Jay Jay
This post is part of my video blog and you can find more information about this video over here.
You can support this channel on Patreon: patreon.com/JohnElliotV
In this video we play around with the 2.13″ and 2.9″ WeAct Studio Epaper Modules available here: WeAct 2.9” 2.13″ 2.9 2.13 Inch Epaper Module E-paper E-Ink EInk Display Screen SPI Black-White Black-White-Red.
As I mention in the video I was having a hard time getting good solder joints from my Horusdy Soldering Station. This was annoying me so much that I went and purchased a new soldering iron! My new iron is an Metcal PS-900 Soldering Station and I love it! This is what a soldering iron should be!
We use the Arduino IDE and the sample code from WeAct Studio but we don’t successfully load content into our Epaper Module.
We use the Rigol MSO5074 Mixed Signal Oscilloscope to and the Rigol PLA2216 Logic Probe to wire up a Logic Analyzer to instrument out circuit, but we don’t follow through with that in the end. We run out of time. We will try again another day.
