The "dyna-micro"/"MMD-1" was the world's first true single board computer. [citation needed] The MMD-1 had all components on a single printed circuit board, including memory, I/O, user input device, and a display. Nothing external to the single board except power was required to both program and run the MMD-1. The original design of the MMD-1 was called the "dyna-micro", but it was soon re-branded as the "MMD-1" List of single-board computers – computers built on a single circuit board, with microprocessor(s), memory, input/output (I/O) and other features required of a functional computer.

Figure_01.jpg (451×780) Weller Magnastat Autopsy and Repair » Code and Life. Immediately after soldering together my USB password thingy, my solder iron, the family heirloom Weller Magnastat stopped working.
Some investigation showed that the base station was providing 24V AC voltage just fine, so I decided to unassemble the handpiece to see if something could be done. Here’s what I found: It turned out my iron was salvageable; read on to learn a bit about the Magnastat and how I was able to repair mine. Magnastat basics The construction of the device is surprisingly simple (see this image): The first (blue) wire from A/C power unit goes straight to the heating element (first red wire with black tube around it). A long tube goes “out” the handle part into the iron tip, and the tip is placed at the head.
Note that in my model the tip and the magnastat are one solid piece (magnastat is in the base of the tip), newer models have a separate magnastat and tip, and you can change the target temperature just by changing the magnastat part. Reviving the old Weller. Système canadien de référence spatiale - Calcul inverse géodésique Démonstration en ligne. News: CGVD2013 is now available!
Natural Resources Canada has released the Canadian Geodetic Vertical Datum of 2013 (CGVD2013), which is now the new reference standard for heights across Canada. This new height reference system is replacing the Canadian Geodetic Vertical Datum of 1928 (CGVD28), which was adopted officially by an Order in Council in 1935. Read more Geodetic reference systems stem from the need to provide a consistent and integrated reference surface for data analysis.
Applications include surveying, mapping, navigation, remote sensing and mineral exploration amongst others. This site provides end-users with the geodetic data and tools they need for a range of commercial and private uses. Date modified:
