Notes

• Low active signals have a "-" prefix.
• 1) These signals are required only for 16 bit accesses and not required when installed in 8 bit systems. Devices should allow for 3-state signals not to consume current.
• 2) The signal should be grounded by the host.
• 3) The signal should be tied to VCC by the host.
• 4) The mode is optional for CF+ Cards, but required for CompactFlash Storage Cards.
• 5) The -CSEL signal is ignored by the card in PC Card modes. However, because it is not pulled up on the card in these modes, it should not be left floating by the host in PC Card modes. In these modes, the pin should be connected by the host to PC Card A25 or grounded by the host.
• 6) If DMA operations are not used, the signal should be held high or tied to VCC by the host. For proper operation in older hosts: while DMA operations are not active, the card shall ignore this signal, including a floating condition
• 7) Signal usage in True IDE Mode except when Ultra DMA mode protocol is active.
• 8) Signal usage in True IDE Mode when Ultra DMA mode protocol DMA Write is active.
• 9) Signal usage in True IDE Mode when Ultra DMA mode protocol DMA Read is active.
• 10) Signal usage in PC Card I/O and Memory Mode when Ultra DMA mode protocol DMA Write is active.
• 11) Signal usage in PC Card I/O and Memory Mode when Ultra DMA mode protocol DMA Read is active.
• 12) Signal usage in PC Card I/O and Memory Mode when Ultra DMA protocol is active.
• 13) Signal is a totem-pole output during Ultra DMA data bursts in True IDE mode.

Electrical Description

The CompactFlash Storage Card functions in three basic modes:

• 1) PC Card ATA using I/O Mode
• 2) PC Card ATA using Memory Mode
• 3) True IDE Mode, which is compatible with most disk drives.

CompactFlash Storage Cards are required to support all three modes. The CF+ Cards normally function in the first and second modes, however they can optionally function in True IDE mode. The configuration of the CompactFlash Card shall be controlled using the standard PCMCIA PC Card configuration registers starting at address 200h in the Attribute Memory space of the storage card or for True IDE Mode, pin 9 being grounded. The configuration of the CF+ Card shall be controlled using configuration registers starting at the address defined in the Configuration Tuple (CISTPL_CONFIG) in the Attribute Memory space of the CF+ Card.

Differences Between CF Storage Card and CF Adapter

The CompactFlash Storage Card and the CompactFlash CF+ Card are electrically compatible with the CompactFlash Adapter. When a CompactFlash or CF+ card is installed in a CompactFlash adapter, the combination conforms to the PCMCIA PC Card Standard. CompactFlash products use a 50 pin connector and CompactFlash Adapters use a 68 pin connector. Both connectors use less than 50 signals. Table 50 shows the pinout differences between the CompactFlash Storage/CF+ Card and the CompactFlash Adapter.

Wow → Ring of Life - The Amazing Metal Structure In Fushun China

 

The Ring of Life is a 515-foot (approximately 157 meters) landmark built in the city of Fushun, China.
The landmark is built with an observation deck accessible by elevator, as well as 12,000 LED lights. Having abandoned local entertainment projects due to the small local population, urban planners settled on building a sightseeing landmark instead in order to attract a tourist industry to the region. The structure uses approximately 3,000 tons of steel and cost an estimated $16M U.S. dollars.

Rugged Iris Mechanism

Monday, 11 December 2006

Advantages include capability for full obscuration, low friction, and general adaptability of design.

A rugged iris mechanism has been designed to satisfy several special requirements, including a wide aperture in the “open” position, full obscuration in the “closed” position, ability to function in a cryogenic or other harsh environment, and minimization of friction through minimization of the number of components. An important element of the lowfriction aspect of the design is maximization of the flatness of, and provision of small gaps between, adjacent iris blades. The tolerances of the design can be very loose, accommodating thermal expansions and contractions associated with large temperature excursions. The design is generic in that it is adaptable to a wide range of aperture sizes and can be implemented in a variety of materials to suit the thermal, optical, and mechanical requirements of various applications.

The Iris Is Opened or Closed by turning the outer ring with respect to the inner ring.

The mechanism (see figure) includes an inner flat ring, an outer flat ring, and an even number of iris blades. The iris blades shown in front in the figure are denoted as “upper,” and the iris blades shown partly hidden behind the front ones are denoted as “lower.” Each iris blade is attached to the inner ring by a pivot assembly and to the outer ring by a roller/slider assembly. The upper and lower rings are co-centered and are kept in sliding contact. The iris is opened or closed by turning the outer ring around the center while holding the inner ring stationary. The mechanism is enclosed in a housing (not shown in the figure) that comprises an upper and a lower housing shell. The housing provides part of the sliding support for the outer ring and keeps the two rings aligned as described above. The aforementioned pivot assemblies at the inner ring also serve as spacers for the housing. The lower housing shell contains part of the lower sliding surface and features for mounting the overall mechanism and housing assembly. The upper housing shell contains part of the upper sliding surface.

beer can experiment 

Beercan Iris Experiment

There's nothing like a quick experiment to see what the constraints on the problem are. Beyold, the quick and dirty (actually quite smelly) beercan iris. I just cut the pieces by eye from an old beer can, so they're fairly thin aluminium sheet. I didn't optimize the shape in any way and, for this purpose, I didn't need to deal with a fancy closing mechanism - fingers work fine.
Conclusions:

• It does close completely (I didn't think it would). Or as near as makes no difference.
• Whatever you make the petals out of, it had better be flexible. The petals have a noticeable S-shaped bend when the iris is fully closed and the upper cover is on. If they were more rigid it would not close completely.
• My iris would have a problem opening up again - the pivot pins (read "wire brads") stick up just enough that the petals catch on them as they open. Perhaps the petals should have been wider at the outside end, so they didn't clear the pivot pin of the next petal when fully closed?

Anyway, hope that helps you. Certainly helped me understand the problem a bit better.

mini teardrop trailer: how to

frame of a vehicle

AEROLUX TRAILER NEWS              

      During the 1930s there was a boom in travel trailer popularity. This was spawned by the desire to travel, despite the economic woes of the time. The trailer could now take the place of expensive lodging,restaurants and commercial travel.

By the end of the decade there was a burgeoning interest in smaller,aerodynamic,owner built trailers. These evolved into the very popular 1940s "teardrop" trailers that were such an efficient design that they have been little changed in 70 years!

Since the onset,the standard formula for construction of the trailer body has been a set of flat plywood sides cut in a streamline shape. The front,roof and rear hatch are then formed by sheet goods, aluminum,fabric or wood attached between the sides giving the trailer body that unique teardrop look.

During the last few years, custom car designer/builder Marty Martino's imagination has given thought to what if......... In the late 1930s ,the teardrop trailer had been styled by the premier automotive designers of the Streamline Modern era ?  i.e. Gordon Buehrig,John Tjaarda , Figoni et Falaschi . The new design focused on adding sculptured form to the normally flat sides and simple fenders in use for the last seven decades.   The result is a trailer design that might have startled visitors at the 1939 New York Worlds Fair!

As it happened , vintage Rolls Royce parts dealer,David Rogers saw some of the sketches that Marty had been working on and was immediately intrigued! His first question was "why aren't we building these? David then brainstormed with Marty to hone and detail the design.

Thus was born, the "Aerolux" trailer styling kit.

It was then further tweaked into a production fiberglass kit that can be added to a teardrop trailer under construction.

While it is possible to retro fit the kit to an existing 8 foot teardrop trailer, it would likely require extensive modification to that existing trailer.

The kit consist of both sides, two outer doors,two fender skirts and a rear hatch "speed blade" ,all produced in the USA of durable quality fiberglass.

Please note that the builder still needs to supply a suitable trailer chassis plus materials for completion as the Aerolux kit consist of the exterior styling parts only.

It is recommended that after installation of the Aerolux body parts,that they be sanded ,primed and painted with automotive quality materials.

We will be adding suggested chassis dimensions and sources for other parts in upcoming blog post. We also invite experienced travel trailer builders to ad suggestions .

The kits are currently availble and in stock.   The seven piece kit is $2,295  f.o.b. Greenville South Carolina USA.

The fine print.....

There is no warranty implied or expressed as to the construction or usage of any object incorporating the Aerolux trailer kit. It is the purchaser's responsibility to determine its fitness for a particular purpose,construction methods and use.

A note to copycats, The Aerolux trailer name and the body design are intellectually protected.     

Infringements will be vigilantly prosecuted.

Building the Aerolux teardrop trailer, the Chassis

In this post we are including the suggested chassis dimensions . 
  The maximum distance between the outside of the frame and the 
Outside of the wheel/tire is nessasary so as to allow for the fender skirt's clearance to the tire.  The Aerolux is a nominal 8 ft long trailer like most traditional teardrops ,however the sides are about 3 inches longer at the floor level. If you are using an exsisting 8 ft trailer Chassis you will probably want to mount the body sides with the 3 inches overhanging in the rear .

Aerolux trailer photos

This photo shows the 7 parts that make up the Aerolux kit. They are the two sides with integral fenders,the two outer doors , two fender skirts and the speed blade center fin.

Here an Aerolux teardrop trailer is completed using aluminum for the outer roof and hatch cover . The fiberglass and chassis are painted in a 1939 automotive pea green. 

        the highly sculpted sides of the Aerolux gives the owner an infinite choice in personalised custom finishing . 

          Below are two examples of possible custom paint schemes that might be used to individualize your Aerolux.
