The Motorola smart card sample is from the very early 90s or the late 80s. Motorola became very successful in the early days of smart cards providing 8 bit microcontrollers to companies such as Gemplus and Schlumberger. The smart card was first developed in France. The first GSM mobile phones had compete credit card sized smart cards inserted, before it made sense to provide a smaller SIM card.
The Hughes ID proximity card was developed in the 90s. Hughes were an early leader in the RFID market. The format is pretty much unchanged today. Inside the card is a coil (antenna), chip capacitor and an RFID chip.
Microchip announced an expansion of its eXtreme Low Power (XLP) PIC® microcontrollers (MCUs) with the PIC24F “GB2” family. This new family features an integrated hardware crypto engine, a Random Number Generator (RNG) and One-Time-Programmable (OTP) key storage for protecting data in embedded applications. The PIC24F “GB2” devices offer up to 128 KB Flash and 8 KB RAM in small 28- or 44-pin packages, for battery-operated or portable applications such as “Internet of Things” (IoT) sensor nodes, access control systems and door locks.

This is a re-shoot of an old chip I opened up previously. I knew at the time that I could only see the metal layers and I needed a metallurgical scope to see anything else, so here we are.
Thanks to the improved camera and scope I can make out smaller details. According to the datasheet this chip has 128 Bytes of onboard SRAM and there are 32 rows and 32 columns in the mid-right block which equates to 1024 bits or 128 Bytes. Because of this I am fairly confident that block is the SRAM and the other two are the ROM.
This was pulled from an old opto-mechanical mouse which used a serial RS-232 connector. The top of the mouse and the ball were missing, so I was unable to identify the model. I think it is made by Logitech since the package has that written on it.
It was designed in 1988 and it uses HCMOS and It was based off of the Motorola 6800.

Microchip announced a new series within its high-performance PIC32MZ family of 32-bit microcontrollers (MCUs) that features an integrated hardware floating point unit (FPU) for high performance and lower latency in intensive single and double-precision math applications. This new 48-member PIC32MZ EF series also offers a 12-bit, 18 MSPS analog-to-digital converter (ADC) for a wide array of high-speed, wide-bandwidth applications. Additionally, the PIC32MZ EF supports an extensive DSP instruction set. This combination of DSP instructions, a double-precision FPU and a high-speed ADC improves code density, decreases latency and accelerates performance in process-intensive applications.

Building our own digital clock is one of the dreamed project by most of the hobbyist or anyone that want to learn or involve seriously in the embedded system world; the ability to integrate time, day and date to the embedded system is one of the important knowledge that should be known by any embedded system designer. Today’s technology makes life easier as all these capabilities has already built nicely inside the Maxim (Dallas) DS1307 Real Time Clock (RTC) chip.

Centre compartment of a console record player that I'm retrofitting. This encloses the amplifier, a computer and a microcontroller.
The computer, at left on the vertical board, is a Via Epia M10000, lower power mainboard running Ubuntu server. This computer plays mp3's etc and is accessed through VLC's web interface or ssh. I replaced the CPU fan with a nearly silent one.
The microcontroller, temporarily sitting on a cardboard box on the amp is charge of receiving the remote control commands and forwarding them to the appropriate device and also for controlling digital potentiometers in the preamp/mixer. I am currently using an arduino to prototype.
You can also see the massive vibration isolating shelf that the turntable sits on (unstained wood).

The Nixie Watch project plods on! Software development begins.
Every project needs to go through this phase, at least in my scheme of handling things.
Here we see the Development Environment of Kings hosting an Atmel ATTiny861 microcontroller (MCU). Just out of shot is my laptop, upon which I wrote software for the MCU that causes it to blink an LED. This is a nice quick way to make sure that I haven't fried the chip and that I've wired everything up properly. For the programmers out there, I consider this step to be the "Hello World" of MCU programming - though this implementation is a bit more sophisticated than it needs to be; the LED blink is driven by a timer interrupt.
This version differs from the IN-14 clock version linked above in that it's all powered by batteries. One of the challenges of designing the watch software will be to set it up so that the MCU draws a minimum of power - not a pressing issue for a clock which is going to be plugged in to a wall socket, but critical for a thing like this which I would like to run for months on a trickle of current.
The little black box in the center right contains 2 AA batteries, which are standing in for the single lithium watch battery which will run the MCU in the real watch. Below it is the display power supply with its own battery. Getting the MCU and display working together is going to be the tricky part. To conserve power, the MCU will run a program that will cause it to immediately shut itself off - but not quite all the way off; it'll be just awake enough to notice when the display power supply fires up. That is, when the watch's wearer presses the button to show the time. At that point the chip will awaken, fetch the time from a crystal-based real time clock chip (not yet wired up), and start showing it on the nixies. When the wearer releases the show-time button, the display power supply will be disconnected and the MCU will notice that, stop trying to display the time, and hibernate again.
Interestingly, if you find such things interesting, this is the way most battery powered computerized widgets work; for instance, games on the Nintendo Game Boy (which I used to program, back when I was younger and even dumber) spend most of their time with the main processor asleep like that. At least they do if they were written well.
After a bit more fiddling I will be able to wire this to the display prototype and it will start being a watch - at least in the functional sense. Trying to wear the prototype on your arm would be like wearing a very geeky buckler.
Sorry I haven't been around flickr friends. I've been focusing on other hobbies...here's a dip from a trip to Maker Faire KC (top is from Photomatix and bottom is from Corel PaintShop)

Mounted ZX Spectrum tape covers.
Mounted front panel from a dead, vintage audio amp. Holes are backlit with LEDs and the dials cycle up and down. You can control the speed and lighting by touching the wood on top of the frame - a capacitance based qprox sensor detects the proximity of your hand to act as a switch.
The switch is multimodal; a quick touch cycles the lighting modes to on/dim/off, holding your hand there for 3 seconds enables the speed setting mode - the dial increments one level on the panel meter per 2 seconds held, ie, hold your hand there for 10 seconds and the dials take about 30 mins to cycle, hold it there for 1 second and the dial will cycle at once every 2 seconds.
All control is done with a PIC microcontroller (before I swapped to AVR). This was my first electronics project.
