Fast Clock Display kits unavailable:
The Fast Clock Display is currently not available as a kit. While this continues, we are making our built units available for the same price as our kit: $47.99.
Take advantage of this price while it remains in effect. As usual, quantity discounts apply starting at three units.
We have been fortunate of having a good component inventory that has enabled us to hold all prices for quite some time. We recently had to restock the opto-couplers for our Quad Occupancy Detector and the relay used in The Traverser and current compnent prices are higher. The added cost of a QOD is $1.44 and for The Traverser is $1.58, but our prices for each (kits and built units) will only increase by $1.
NOTE: Our Triple Occupancy Detector price has increased by $0.75 as it has only three opto-couplers, and our Loop Traverser price has not increased as it does not use the relay. Combinations of QOD and Traverser have increased by $1.50
We apppologize for this and hope to be able to source these for a better price in order to lower our prices.
Latest Release of the CROR Available:
We have updated the copy of the Canadian Rail Operating Rules (CROR) that is on the product page for our Signal Animator.
Layout Rewiring Project Article Now Online
The article covering a recent layout rewiring project is now available online here and listed on our Tips & Tricks page. It covers the layout's original design and wiring, how the idea of rewiring came about, the goals developed for the new wiring, and the materials and techniques used.
New Articles in the Works
We continue to develop an article on creating a signal plan. A signal plan maps out where signals will be located, and what type or style of signal is at each location. It also outlines what indications are required, which in turn determines what style of signal is needed. Having all that planned out will then make it easy to determine what will be needed (signals, electronics, etc.) and how they will be wired to provide the expected results. We are hoping to have this article available in by the end of July.
Interested in Expirementing with Occupancy Detection?
While our Quad Occupancy Detector is one of the lowest-cost way to detect occupancy, we have a limited-time special for those wishing to experiment with even less initial cost, and do so without first having to assemble a kit.
We have a limited supply of fully functional "Version 2" QODs available for the low cost of $1 per detector (that's $1 for a single, $2 for double, $3 for triple, and $4 for a fully-populated QOD) plus shipping. Version 2 was the second generation of our detector that pre-dates when we initially started selling the Version 3. These were used on our own layout beginning in 2009 until a recent re-wiring project involved using DIN rail board carriers that the older detector boards do not fit (Version 2 boards are 3" square, while current boards are 2.75" square).
These detectors have the same specifications as our Version 3 QOD. Documentation for the Version 3 QOD can be found at the bottom of our current version documentatoin page. Like the Version 3, these only have a 1x6 header for the outputs, though some are straight and some are right-angle (like the one in the photo to the right). Also like the Version 3, they have a 3 amp maximum block current.
We will have a full count of available units shortly, but in the meantime you can send us an email for details on what is available and how to order them. Regular shipping rates apply, but free drop-off is available in parts of the GTA.
NOTE: These detectors are not ROHS compliant.
Switch Machine Interface Now Available
Our new product, a connection interface for the Tortoise Switch Machine by Circuitron, is now available for ordering.
We now have our installation and assembly instructions for this product on our Documentation Page.
The development of this product is part of the development of our new signalling product line, Signal Master Plus (see our article on the evolution of a Signalling System. As the second set of SPDT contacts are needed for switch position status, an easier way to wire this would be to used a 3-conductor ribbon cable. This new product is available with either a 3-pin header plug (upper image to the right) or a 3-position terminal block (lower image to the right) for the second contacts.
There are two LEDs in series with the motor to provide an easy to see indication of the switch machine's position, provided it continuously receives power. One is green and one is yellow, and when ordering you can select which colour indicates the left position and which colour indicates the right position. We will be adding an application note on translating left/right to normal/reverse in the next few days.
After consulting with initial users of the header version of the SMI, we now provide a right-angled 3-pin header as can be seen in the upper image to the right.
We have added accessory items to our products page. This will include items for use with our products such as IC sockets, header plugs, spacers, and jumpers.
Traverser Power Supplies:
We now have a power supply suitable for the Traverser. It is a "wall wart" type power supply that provides 12 VAC at up to 750 mA, from a 120 VAC outlet (Canada and USA). The price is $8.99 on its own, but will only add $7 to a Traverser/QOD combo. See The Traverser product page for details.
