Design for a stepper motor drive.
The stepper motor drive uses the TMC2100 modules from an old 3D printer (FlashForge Finder). I got this gift from a Fischertechnik forum member. The modules are controlled via a spi connection with my FPGA controller. The FPGA is connected to the Fischertechniek TXT Controller via an I2C line. The TMC2100 modules are in a fixed mode of the 3D printer, there is micro stepping used with 16 fine steps per step. Through the SPI connection I can send the ena, DIR, STEP, CFG0 and CFG4 pin. Because the modules are configured in 16 microsteps, the step pulses can be provided quite quickly. Therefore I controlled the SPI driver from a 4MHz clock so that only 13.5 usec is needed to scan all 24 inputs and outputs. This is much faster than the max step speed needed for the stepper.
The SPI goes to the FPGA chip. This is now programmed as a large I2C chip for the user. Besides this stepper driver there are also modules written for 16 motors, 72 inputs, 36 outputs, and 32 servo motors. All inputs can handle fairly fast pulses especially for quadrature encoders. The motors can run in 5 different modes and operate autonomously. The external I2C user only needs to send a few commands. Timing is no problem at all because the FPGA works much faster than the fastest micro controller. There are almost 1000 bytes of registers provided to support all functions. On the Fischertechnik side I have written a full lib to support all these functions. Through the Robopro software you can now write a program in a few minutes to the motors, servo steppers controls, reads inputs, status reads output line controls. I will give you more information about this later, but this data is so extensive that writing the manual takes a lot of time.

Vintage passenger service modules , called APAX, from passenger aircraft. These modules are located under the seats and provide music and other passenger services, as steward call feature.
Le Corbusier sviluppò il Modulor all'interno della lunga tradizione di Vitruvio, l'uomo vitruviano di Leonardo da Vinci, i lavori di Leon Battista Alberti, e altri tentativi di trovare proporzioni geometriche e matematiche relative al corpo umano e usare queste conoscenze per migliorare sia l'estetica che la funzionalità dell'architettura. Il sistema è basato sulle misure umane, la doppia unità, la sequenza di Fibonacci e la sezione aurea. Le Corbusier lo descriveva come "una gamma di misure armoniose per soddisfare la dimensione umana, applicabile universalmente all'architettura e alle cose meccaniche". Il modulor è anche utile per la rappresentazione della figura umana.

N scale town module -- various kits
The last minute roundabout idea which turned out surprisingly well.
I'll let you ponder over how this was made.
First module using the NELTC mainline standard. I really dig the wedge plate accent on the outside of the ballast. I am reasonably happy with the trees, but may tinker with the tops.
Voskhod 1 descent module, 1964
The three cosmonauts' couches inside Voskhod were only fitted with difficulty, making the crew crane their necks to see the instrument panels. With no space for a means of escape to be fitted, a retrorocket slowed the spacecraft as it returned to Earth, enabling the cosmnauts to remain on board for the entire mission.

Late in the day for the shot and also for this Hard Drive. I have 3 of them that have given up. I wonder if it is this module that's gone. Who knows? Who cares? It's going in the recycling bin once I've broken up the disc.

The day started sunny and calm, but by the time I had done my chores it was cloudy and windy so didn't go on my planned excursion to a waterfall.
Decided to have my first go at Camera School Module 3 indoors. As it was cloudy outside, it was even darker inside and it was impossible to get the degree of blurred water, yet showing a sense of movement, with the recommended CS settings. I found around 1/15-1/30 portrayed this best, but to achieve this a high ISO, coupled with a small F number was required. Another difficulty I had was with the large dynamic range between the dark sink/tiles, and the bright water and the need for a reflector which lightened the darker bits, but also blew the highlights. An ND filter was not required in these dull conditions.
I won't therefore be using any of these shots for homework, but put them up as my first venture into this module. On a bright day this setup might work and I might give it another go with different composition and crockery/containers.
Turns the trusty workhorse "283 into a useful strobist tool. The only downside is that since its just a potentiometer, there are no positive clicks for each setting, so you don't really know if that power level is what you're getting. But its pretty close. It also allows adjustment down to 1/64th power, better than the current 285 HV. "

I got a 283 with AC adapter and the VP-1 module with some Canon film gear. Entire manual scanned here.

Orion is NASA’s next spacecraft for sending humans into space. ESA has designed and is overseeing the development of Orion’s service module, the part of the spacecraft that supplies air, electricity and propulsion.
The second mission with ESA's service module is Exploration Mission-2. This logo shows the Orion spacecraft exploring our Solar System, with the rear view highlighting the service module. The logo includes stylised depictions of Earth, the Moon and Mars – some of Orion’s destinations.
The border includes the abbreviation ESM for European Service Module. Between the distinctive solar wings on the right are the characters “fm-2”, denoting the second Flight Model for the spacecraft's second mission.

The Zeplina Power Module was created to power the worlds largest zeppelin, this piece was destined for stardom as an epic event in history. However, its extreme weight and the fact it was mounted at the front of the zeppelin meant that the nose couldn't get of the ground, even with the excessive amount of power it produced. The zeppelin cruised along, bum in the air, nose to the ground like a dog sniffing out the trail of dragged sausages. The zeppelin company refused to pay for the item, so I turned it into a lamp and this (almost) piece of history is for sale!
This is an actual lunar module, one of 12 built for Project Apollo. It was meant to be used in low Earth orbit to test the techniques of separation, rendezvous, and docking with the command and service module. The second of two such test vehicles, its mission was cancelled because of the complete success of the first flight.
The lunar module had two stages. The descent (lower) stage was equipped with a rocket motor to slow the rate of descent to the lunar surface. It contained exploration equipment and remained on the Moon when the astronauts left. The ascent (upper) stage contained the crew compartment and a rocket motor to return the astronauts to the orbiting command module. After the crew entered the command module for the trip back to Earth, the lunar module was released and eventually crashed into the Moon.

Apollo 14 Command module on display at Kenedy Space Center. Mission nr. 14 was the next successful mission after Apollo 13 "Failure is not an option" safe return.
Well known "Houston, we have a problem" is quite often misinterpreted and the actual wording used by crew was "Houston, we've had a problem here" instead.
It is rather impressive to see massive rocket boosters next to small module accommodating crew of 3 people.

The "Y Module" was created in 1988 and published in "Modular Origami" a self-publication. The module, folded from square papers is based on the 60 degree geometry. When assembled, a "Y" band is form on the triangular faces of the model and a small pinwheel motif on all the corners.
3 of the 5 Platonic Solids can be assembled from this module. They are the Tetrahedron, the Octahedron and the Icosahedron. All of these polyhedra have triangular faces.
6 Modules, folded from 15cm square Kami are used to assemble the Tetrahedron.

The City Space theme continues to inspire. I wanted to use the curved quarter panels as a windscreen, and by excellent luck had the matching curve plate in sand blue. From then on it was just a matter of mixing the design cues and colour scheme from the sets with my build.
Rather pleased with this, looks chunky and industrial near-future. The crane, while functional, can't lift the module without ripping itself apart. Oh well.
Probably won't take any more pictures of the module itself either, it's just an empty shell that seems to be more like a double-decker carriage on a scenic train than a science module. Some more work on that will be required, I think. But that's a problem for another time. I already have an idea for a larger build that will incorporate four of these modules.

This card contained the mircoprocessor for the floppy disk interface. It also contained the options paid for and activated for the customer. The options module can be seen as the small box on the front right of the card. This modile was easily changed.

5 Pentagon Modules are used to make the coaster. The modules are folded from 7.5cm squares of Japanese Foil-backed washi.
The coaster model is assembled without glue and has the same pattern for the front and back. 12 such coasters can be assembled to form a Dodecahedron. Altogether, 60 modules are required...later.
This model was created in 1990 and first published in Modular Origami [self-publication]. The model is also published in "The New Origami" by Steve & Megumi Biddle in 1993 and later in the British Origami Society Booklet #58.
