Posting this here, better late than never:
Curtesy of Sam Zeloof I came around the fact that I’ve got a good part of a FSTM in a cupboard here.
Apparently my choice of purchasing the HD-DVD drive for the Xbox 360 will ultimately pay off!! As we all know Bluray won that format war back in the days.
But now it seems that this below would be useable for something:
Over the life of nuclear fuel, inhomogeneous structures develop, negatively impacting thermal properties. New fuels are under development, but require more accurate knowledge of how the properties change to model performance and determine safe operational conditions.
Measurement systems capable of small–scale, pointwise thermal property measurements and low cost are necessary to measure these properties and integrate into hot cells where electronics are likely to fail during fuel investigation. This project develops a cheaper, smaller, and easily replaceable Fluorescent Scanning Thermal Microscope (FSTM) using the blue laser and focusing circuitry from an Xbox HD-DVD player.The Design, Construction, and Thermal Diffusivity Measurements of the Fluorescent Scanning Thermal Microscope (FSTM)
As mentioned, Sam Zeloof shows off the actual chip in more detail:

I played with SDR – Software Defined Radio – back in 2013. I’ve still got the equipment around.
Now that I am thinking about it – there is a practical use-case that I will look into in the coming months for sure for it. And just to mention this use case here: With SDR I could create a more versatile 443/886 Mhz receiver.
Anyhow. SDR hardware allows you to access a whole spectrum of radiosignals at once. And a common way to visualize the spectrum is to draw the amplitudes in a line add each new measurement as a new line – color/brightness coded.
What you get is some sort of waterfall diagram that looks like this:
Hertzian Landscapes (2019) is a live visualization of the radio spectrum. Unlike visible light, waves in the radio spectrum cannot be perceived by us directly yet this space is teeming with human activity. Hertzian Landscapes employs a digital receiver to scan large swaths of radio spectrum in near real-time and visualizes thousands of signals into a panoramic electromagnetic landscape. Users can zoom in to specific frequencies by positioning themselves in front of the panorama as if controlling a radio tuner with their body, giving them a sense of walking through the spectrum.http://www.hertzianlandscapes.com/
From radio broadcasts to weather satellites and from medical implants to aeronautical navigation, the radio spectrum is divided into hundreds of designated slices each tied to a specific application. Based on a localized frequency database that describes these slices, signals are annotated to provide information about their theoretical type and application.
After looking into the NES emulation written entirely in C# I came across a similar approach using C# to emulate a full and much more complex PlayStation 1.
I then stumbled on this very early version of a PSX Emulator in C#.
Now, if you were to theoretically have a Playtation SCPH1001.BIN BIOS and then physically owned a Playstation (as I do) and then created a BIN file from your physical copy of Crash Bandicoot, you could happily run it as you can see in the screenshot below.

You might have asked yourself how it is that some phones charge up faster than others. Maybe the same phone charges at different speed when you’re using a different cable or power supply. It even might not charge at all.
There is some very complicated trickery in place to make those cables and power supplies do things in combination with the active devices like phones. Many of this is implemented by standards like “Quick Charge”:
Quick Charge is a technology found in QualcommSoCs, used in devices such as mobile phones, for managing power delivered over USB. It offers more power and thus charges batteries in devices faster than standard USB rates allow. Quick Charge 2 onwards technology is primarily used for wall adaptors, but it is also implemented in car chargers and powerbanks (For both input and output power delivery).Wikipedia: Quick Charge
So in a nutshell: If you are able to speak the quick charge protocol, and with the right cable and power supply, you are able to get anything between 3.6 and 20V out of such a combination by just telling the power supply to do so.
This is great for maker projects in need of more power. There’s lots of things to consider and be cautious about.
“Speaking” the protocol just got easier though. You can take this open source library and “power up your project”:
The above mentioned usage-code will give you 12V output from the power supply. Of course you can also do…:
Be aware that your project needs to be aware of the (higher) voltage. It’s really not something you should just try. But you knew that.
More on Quick Charge also here.
We’ve got several quite big fish tanks in our house. Mainly used by freshwater turtles.
These turtles need to be fed every once in a while. And while this is not an issue normally it’s an issue if you leave the house for travel for an extended period of time.
Of course there are humans checking on everything in the house regularly but as much as can be automated should and will be automated in our household. So the requirement wa to have the turtle feeding automated.
To achieve this is would be necessary to have a fixed amount of turtle food be dispensed into the tanks on a plan and with some checks in the background (like water quality and such).
It’s been quite a hassle to come up with a plan how the hardware should look like and work. And ultimately i’ve settled on retrofitting an off-the-shelf fish pond feeder to become controllable through MQTT.
The pond feeder I’ve found and used is this one:
It’s not really worth linking to a specific product detail page as this sort of feeder is available under hundreds of different names. It always looks the same and is priced right around the same.
If you want to build this yourself, you want one that looks like the above. I’ve bought 3 of them and they all seem to come out of the same factory somewhere in China.
Anyway. If you got one you can easily open it up and start modifying it.
The functional principle of the feeder is rather simple:
- turn the feeder wheel
- take the micro-switch status in account – when it’s pressed down the wheel must be pushing against it
- turn it until the micro-switch is not pressed anymore
- turn some more until it’s pressed again
Simple. Since the switch-status is not known on power loss / reboot a calibration run is necessary (even with the factory electronics) every time it boots up.
After opening the feeder I’ve cut the two cables going to the motor as well as the micro-switch cables. I’ve added a 4-Pin JST-XH connector to both ends. So I can reconnect it to original state if desired.
These are all the parts needed:
I am using a Wemos D1 Mini and a couple of additional components apart from the prototype board:
A PN2222 NPN transistor, a rectifier diode 1N4007 and a 220 Ohm resistor.
I’ve connected everything according to this schematic I’ve drawn with Fritzing:
I’ve then prototyped away and put everything on the PCB. Of course with very limited solderig skill:
As you can see the JST-XH connector on Motor+Switch can now be connected easily to the PCB with all the parts.
Make sure you check polarity and that you did correctly hook up the motor and switch.
When done correctly the PCB (I’ve used 40mm x 60mm prototype pcb) and all cables will fit into the case. There’s plenty of room and I’ve put it to the side of it. I’ve also directly connected an USB cable to the USB port of the Wemos D1 Mini. As long as you put at least 1A into it it will all work.
Since the Wemos D1 Mini sports an ESP8266 and is well supported by Arduino it was clear to me to use Arduino IDE for the software portion of this project.
Of course everything, from schematics to the sourcecode is available as open source.
To get everything running you need to modify the .ino file in the src folder like so:
What you need to configure:
- the output pins you have chosen – D1+D2 are pre-configured
- WiFi SSID + PASS
- MQTT Server (IP(+Username+PW))
- MQTT Topic prefix
Commands that can be sent through mqtt to the /feed topic.
There are overall two MQTT topics:
This topic will hold the current state of the feeder. It will show a number starting from 0 up. When the feeder is ready it will be 0. When it’s currently feeding it will be 1 and up – counting down for every successfull turn done. There is an safety cut-off for the motor. If the motor is longer active than configured in the MaximumMotorRuntime variable it will shut-off by itself and set the state to -1.
This topic acts as the command topic to start / control the feeding process. If you want to start the process you would send the number of turns you want to happen. So 1 to 5 seems reasonable. The feeder will show the progress in the /state topic. You can update the amount any time to shorten / lengthen the process. On the very first feed request after initial power-up / reboot the feeder will do a calibration run. This is to make sure that all the wheels are in the right position to work flawlessly.
So if you want to make it start feeding 3 times:
mosquitto_pub -t house/stappenbach/feeder/feeder-00F3B839/feed -m 3
And if you want to see the state of the feeder:
mosquitto_sub -v -t house/stappenbach/feeder/feeder-00F3B839/state
All in all there are 3 of these going to be running in our household and the feeding is going to be controlled either by Alexa voice commands or through Node-Red automation.
I am still working on it – but it is coming together nicely. During the next vacation our fish tanks are going to be well fed.

You might, or might not be aware of my passion for black clothing. I like the simplicity and absence of noise.
Anyway. You might not be aware of the wonderful world of black as-in paint.
Apparently the current record holder in blackness (measured in percent absorption of visible light) is a product called “Vanta Black”.
Vantablack is a material developed by Surrey NanoSystems in the United Kingdom and is one of the darkest substances known, absorbing up to 99.96% of visible light (at 663 nm if the light is perpendicular to the material).Wikipedia: Vantablack
The name is a compound of the acronym VANTA (vertically aligned carbon nanotube arrays) and the color black.
Unfortunately this blackest-of-black coating is not readily available for purchase. Export rules apply and so it’s usually not sold to civilians at all.
“What is the next best thing?”, you ask. Well it’s BLACK 2.0.
I am running most of my in-house infrastructure based on Docker these days…
Docker is a set of platform-as-a-service (PaaS) products that use operating-system-level virtualization to deliver software in packages called containers. Containers are isolated from one another and bundle their own software, libraries and configuration files; they can communicate with each other through well-defined channels.
All containers are run by a single operating-system kernel and are thus more lightweight than virtual machines.Wikipedia: Docker
And given the above definition it’s fairly easy to create and run containers of things like command-line tools and background servers/services. But due to the nature of Docker being “terminal only” by default it’s quite hard to do anything UI related.
But there is a way. By using the VNC protocol to get access to the graphical user interface we can set-up a container running a fully-fledge Linux Desktop and we can connect directly to this container.
I am using something I call “throw-away linux desktop containers” all day every day for various needs and uses. Everytime I start such a container this container is brand-new and ready to be used.
Actually when I start it the process looks like this:
As you can see when the container starts-up it asks for a password to be set. This is the password needed to be entered when the VNC client connects to the container.
And when you are connected, this is what you get:
I am sharing my scripts and Dockerfile with you so you can use it yourself. If you put a bit more time into it you can even customize it to your specific needs. At this point it’s based on Ubuntu 18.04 and starts-up a ubuntu-mate desktop environment in it’s default configuration.
When you log into the container it will log you in as root – but effectively you won’t be able to really screw around with the host machine as the container is still isolating you from the host. Nevertheless be aware that the container has some quirks and is run in extended privileges mode.
Chromium will be pre-installed as a browser but you will find that it won’t start up. That’s because Chromium won’t start up if you attempt a start as root user.
Maybe you want to give EasyEDA a try as it’s in-browser experience is better than anything I had come across so far. Granted I am not doing PCBs regularly but nevertheless – whenever I tried with the programs I’ve got recommended it wasn’t as straight forward as it is with this tool.
