I found this kickass resource: Super Nintendo Development Wiki. See for instance Schematics, Ports, and Pinouts.
One of my YouTube viewers Max donated some stuff to the channel today. How cool is that!? Expect to see some Nintendo awesomeness in the near future. <3
I think my next laptop might be a Framework Laptop.

Silly Job Title: Ohm Oracle
Old Book: Electric Circuits by J. Richard Johnson published 1984 with 888 pages.
Today we pop open a few bags of stuff that has arrived in the mail.
I mention about the trouble I had with my Western Digital Purple drives.
I mention about my new Western Digital Black 1TB NVMe M.2 SSD WDS100T3X0E drives.
I mention about my Educational 555 PCBs which have arrived from PCBWay. The website of the designer is given as: basitelektronikprojeler.blogspot.com.
The systems of units mentioned in the old book Electric Circuits are discussed at MKS system of units and Centimetre–gram–second system of units.
The 256GB M.2 NVMe drives I got to use as my ZFS L2ARC cache are these: TOSHIBA KIOXIA 256GB BG5 NVMe SSD M.2 2280 – NEW GEN4.
The automotive fuses I got are these ones: Car Fuse Blade Fuse Kit Fuses Automatic Truck Blade The Fuse Insurance Insert Insurance of Xenon Piece Lights Auto Accessories.
The test clips I got are these ones: 10X Universal Chip clamp micro IC clamp SOP SOIC TSOP MSOP SSOP SMD IC Test Clip pin Socket Adpter Programmer for logic analyzer.
The book which arrived in the mail was The SCSI Bus and Ide Interface: Protocols, Applications and Programming (2nd Edition) by Friedhelm Schmidt published 1997 with 396 pages.

ChatGPT told me this:
ChatGPT 3.5
User:
are SMART errors good enough reason for RMA?ChatGPT:
SMART (Self-Monitoring, Analysis, and Reporting Technology) errors are indicators that a storage device, such as a hard drive or SSD, has detected potential issues with its health or performance. SMART errors can cover a range of issues, including bad sectors, high temperature readings, and other abnormalities.Whether SMART errors are considered a good enough reason for a Return Merchandise Authorization (RMA) depends on the severity and type of errors, as well as the specific policies of the manufacturer or seller. Here are some general considerations:
Severity of Errors: Some SMART errors may be relatively minor and not immediately indicative of a catastrophic failure. Others, particularly those related to critical components like bad sectors, can be more serious. If the errors suggest a high risk of imminent failure, it could be a valid reason for an RMA.
Warranty Status: If your device is still under warranty, the presence of SMART errors is often a reasonable cause for an RMA. Warranty policies vary between manufacturers, so it’s important to check the terms and conditions provided by the company.
Manufacturer’s Policies: Different manufacturers have different policies regarding what constitutes a valid reason for an RMA. Some companies may require a certain threshold of errors or specific criteria to be met before they authorize a return.
Backup and Data Loss: Before seeking an RMA, it’s crucial to back up your data, especially if the SMART errors suggest potential drive failure. Some manufacturers may request proof that you’ve backed up your data before processing an RMA.
Communication with Support: If you’re experiencing SMART errors and are considering an RMA, it’s a good idea to contact the manufacturer’s customer support. They can provide guidance on whether the errors are within acceptable limits or if they warrant a replacement.
Remember that not all SMART errors are equal, and some devices may continue to function adequately despite certain types of errors. However, if you’re concerned about the health of your storage device and it’s under warranty, it’s generally a good idea to reach out to the manufacturer for guidance on whether an RMA is necessary.
I got two Western Digital 8TB SATA Purples which arrived from Amazon today. When I plugged them into my first computer the BIOS hung for a few minutes then powered off the computer. Huh? So I took the drives out and put them in another computer, and before the BIOS screen I got this:
I tried a few passwords (blank, “admin”, etc) but nothing worked. I searched for the default password, couldn’t find one. I installed the WD Security software on my MacBook Pro and tried connecting the drive with two different USB adapters, but nothing worked.
I’m just gonna send these back and never buy Western Digital purples again.
My RMA note are:
Why are you returning this? Item defective or doesn’t work
Comments (required): It asked me for a password, but it didn’t give me the password. I wasted a lot of time on this trying to find and fix the problem.
Today in our household we are having 32x TongWei 415W solar panels installed on the roof.

Silly Job Title: Grounding Genius
Old Book: Industrial Electronics Reference Book by Electronics Engineers of the Westinghouse Electric Corporation published 1948 with 680 pages.
Today we teardown a homemade continuity tester which I put together for use before I had a multimeter, so that was in the early days of my new lab, circa August 2021.
While I was preparing the links for this blog post I discovered that the plastic case I used for the continuity tester was the HB5610 Black Hand-held Electronic Enclosure from Jaycar. I purchased one of these for AU$9.95 back in August 2021, which was around the time that I made this continuity tester.
I subsequently purchased a ten pack of similar plastic cases from AliExpress for AU$64.55 (inc shipping) in March 2022. I went to find the AliExpress listing so I could link you to it, but it’s an old listing and has been taken down. I did search for an equivalent product but didn’t find what I was looking for. The dimensions are roughly 70mm x 135mm x 24mm and there is a facility for 2x AA batteries built in.
The multimeters I use/mention in this video are:
The multimeter I mention I want to get is this one: EEVblog 121GW Multimeter.
What I say in the video about active vs passive piezoelectric buzzers is correct. The active buzzer will do the buzzing for you, all you need to do is supply some power. The passive buzzer will need an input signal in addition to power, so some sort of oscillator if you want to generate a tone.
I knocked up a schematic for this continuity tester, something like this:
I’m gonna try getting some PCBs made for this circuit from PCBWay, because I’m still trying to learn everything I can about that process!

A quick search for arduino fuses programming turned up a bunch of results:
