Sharing PCB designs on PCBWay
Over on An Absolute Beginners Guide To Designing PCBs using Easy EDA – Make PCB From A Schematic I learned about How to Share Projects in PCBWay Community. Seems like a good service to me, haven’t used it yet but do intend to check it out.
Unboxing #9: Unboxing of Sudake SDK07 and SKD08 IC Clip SMD Gripper Test Probe | In The Lab

Silly Job Title: Hack In Residence
Today: another unboxing video! This time we’re taking a look at the Sudake SDK07 and SKD08 IC clips / SMD grippers / test probes.
Originally I was going to demo these things in this video too, but the test circuit took like two hours to make, and then when I turned it on it didn’t even work, so I cancelled that and now this is just an unboxing video and not a demo. Stay tuned for the demo which I will do, just when I can find some more time.
These test clips are really great, they let you attach a probe to the foot of an integrated circuit or a surface mount device.
Be warned: there’s a bit of swearing and bad language in this video. What can I say? I’m just a passionate individual, ya know? :P

Unboxing #8: Unboxing of Mini Classic Game Console | Learning Electronics In The Lab With Jay Jay

It’s the In The Lab With Jay Jay Halloween Special! This evening: another unboxing video! This time we’re taking a look at my retro gaming console: The Mini Classic Game Console. Complete with 620 odd games!
I picked this thing up at Vinnies (the thrift store) for fifteen Aussie buckaroos.
The main circuit board looks like this:
I found the S71PL256NC0HFW5U2 which is a 64Mb flash memory. The details of the other circuitry was obscured.
Here is the list of games on this thing:
And this is the manual:
I managed to get this thing wired through an AV to HDMI adapter, then a HDMI to USB adapter, so in the last half of the video you can see me demoing a few of the games and scrolling through the full list of games.
Oh, and in this video I read “NTSL” on the manual and say “they got that wrong, it’s NTSA”, but *I* got that wrong, and it’s “NTSC”. The American video standard. In Australia almost everything is PAL.

Unboxing #7: Unboxing of FILCO Majestouch 2SS Edition 104-key and tenkeyless keyboards | In The Lab

Silly Job Title: Sparky
Happy Halloween! Today: another unboxing video! This time we’re taking a look at my two new mechanical keyboards from FILCO (affiliate links):
- Full size 104-key: FILCO Majestouch 2SS Edition FKBN104MSS/ECSP2B-RKL Full Size English Layout Cherry MX Speed Silver Axis with 3 Red Key Locks, Black
- Tenkeyless 87-key: FILCO Majestouch 2SS Edition Tenkeyless English Layout Cherry MX Speed Silver Axis with 3 Red Key Locks, Black FKBN87MSS/ECSP2B-RKL
As I mention in the video I usually like to purchase my mechanical keyboards from WASD Keyboards in California. They make excellent keyboards but just a bit too pricey for me at the moment. Instead of purchasing from WASD Keyboards I picked these keyboards up from Amazon Australia and I paid AU$202.55 (US$130) for the 104-key keyboard and AU$188.89 (US$120) for the 87-key keyboard which was roughly half of what I would have had to pay if I purchased from WASD Keyboards.
Both of these FILCO Majestouch 2SS Edition keyboards come with Cherry MX Speed Silver switches. If you’re into mechanical keyboards definitely give these switches a try; now that I’m used to them I will accept nothing less.
It was a bit disappointing that while doing the unboxing I discovered some of the keys had fallen loose during shipping. I have since plugged in and tested the keyboard (I’m using it now in fact) and everything seems to be working okay, so no harm no foul.

Unboxing #6: Unboxing of K-CEVE AM-KVM401-K and KC-KVM401A 4-port HDMI KVM switches | In The Lab

Silly Job Title: Current Commander
Today: another unboxing video! I do these, not because I think that my regular viewers are going to be particularly interested, but because you really only get the opportunity to do these on the day that new equipment arrives, and I figure it might be helpful for people who search for unboxing videos for a particular product, so they can see what’s in the box before they make a purchasing decision.
This video is an unboxing of two different 4-port HDMI KVM switches. I would give you affiliate links but these don’t seem to be available in the USA, so here are the non-affiliated Amazon Australia links:
- K-CEVE AM-KVM401-K: KVM Switch HDMI, Kvm Switch 4 Port 4 in 1 Out USB KVM Switcher for 4 Computers Share one HD Monitor and 4 USB 2.0 Devices, Support UHB 4K@60Hz and Wireless Keyboard and Mouse
- K-CEVE KC-KVM401A: KVM Switch HDMI 4 Port, USB 3.0 KVM Switches 4K 60HZ HDMI and USB Switcher with EDID Simulator for 4 Computers Share Keyboard Mouse Printer Scanner and One HD Monitor with 1 External Button Switch
For the record I paid AU$64.56 for the AM-KVM401-K (US$40) and AU$84.14 for the KC-KVM401A (US$55). I don’t know what algorithm is in charge of pricing at Amazon but the prices seem to have gone way up since I purchased these things two days ago, now the AM-KVM401-K is AU$75.96 and the KC-KVM401A is AU$98.99, so not sure what’s up with that (but I do NOT like the idea that Amazon has a pricing system that isn’t offering all shoppers the same price all the time, which this smells like).
I reckon the K-CEVE marketing department is going to bit pretty upset with engineering or manufacturing about this, but when I was unboxing the AM-KVM401-K the front panel push button switch just dead set fell out! That’s gotta be embarrassing for someone.
Having done the unboxing I’ve decided I’m gonna try the larger KC-KVM401A unit first. Its larger size is a disadvantage but I like the fact that it has USB-A instead of USB-C inputs and I’m also happy that it has a dedicated 5V power rail, the AM-KVM401-K is powered off the USB bus which is less desirable.
I will post another article later to let you know how I went when I actually plug these things in, which I haven’t actually done yet.

Electronics Project #1: ALKOY Capacitor Discharge Pen Teardown | In The Lab With Jay Jay

Silly Job Title: Electron Herder
This video is a teardown of the ALKOY Capacitor Discharge Pen which I did for YouTube user t1d100 who asked me about it over here: Demo of the ALKOY Capacitor Discharge Pen | In The Lab With Jay Jay.
I made a bunch of mistakes while making this video, so please bear with me. I tried to add some captions to explain things when I went wrong.
The discharge pen that I have was purchased from Amazon Australia here: 1000V Portable Capacitor Discharge Pen High Voltage Quick Discharging Tool Constant Discharge Pen Electronic Repairs Discharge Pen ALKOY.
There seems to be a similar product available from Amazon USA here: YEKMLCO Capacitor Discharge Pen Fast Discharging High Voltage 1000V Repair Tool Discharger for Electronic Safety Intelligent (affiliate link).
In the video you can watch me break this thing open. I didn’t exactly know how to do it, and I permanently damaged the device while opening it. In the end I wasn’t 100% sure what the safe and proper way to open these things really is. Giving it a mighty pull might work, otherwise you will need to leverage off some friction locks.
Before I broke the device open I tried to measure the resistance across its probes, but all three measurement devices reported open circuit. The device doesn’t seem to engage the resistor until it detects a voltage.
Eventually I got the device open, you can see some photos of the circuit board below, and I make some attempt to identify the components.
The MB10F on the top is a bridge rectifier, the M7F in the middle is a rectifying diode, and the resistor at the bottom is 2MΩ. In the video I say that the resistor is a “two ohm resistor”, but it is actually a “two MEGA ohm resistor” (I knew that, I just misspoke).
I’m not 100% sure what the CS01N100 A3R is, but it seems than an CS01N100 A4R is a silicon N-Channel Power MOSFET, so I think that’s probably what that is.
As I broke this device during the teardown I have purchased myself a replacement device for AU$23.02.
In the video I use the following equipment (affiliate links where possible):
In the video I have trouble with the connections into the DSO-TC3, the connections are documented here: FNIRSI DSO-TC3.
