Open Hardware Repository — проект созданный сотрудниками CERN для организации сообщества вокруг проектов с открытой аппаратной архитектурой и их реализации. Open Source Hardware Association — создана для продвижения Open Source устройств, дизайн которых свободно доступен под открытой лицензией. Такие устройства, микросхемы, печатные платы вот уже полтора года помечаются логотипом с шестерёнкой, так что каждый сразу видит, что это — свободное устройство. Базовые требования, которые нужно соблюдать при разработке открытого аппаратного обеспечения  Вот небольшой список известных Open Source Hardware проектов.

The current selection tool, that is compatible with the GAL, does not provide enough means to perform all actions required to design a PCB. To make it fully operational, more functionality is required. Some of the following functionality is currently available for testing in the product branch.

Deletes selected items or groups of items. Activated by a hotkey e. Delete or a command in the Context Menu CM. Shortcuts should be consistent with the legacy KiCad edit panel.

The context menu entries should open hardware repository cern zoom accessible by hotkeys and let the user change the grid settings by keys combination. To sum up:. In the context menu there could be only one unit per row either mm or mils, not both at the same timeas users usually know the value expressed in one of the units and do not need to know the equivalent in the other one. Another possibility is to display values using only the currently selected unit.

The zoom options are right now fully available open hardware repository cern zoom the context menu and hotkeys toobut they could be grouped together into one menu position that is open hardware repository cern zoom expanded to all options please have a look at the CM plan at the end of the document and accessible by hotkeys in a similar way to the grid settings. Instead, there could be a dockable window with checkboxes that prevents selection of given items or filters them out cerh the selection is performed.

Then open hardware repository cern zoom with available actions that apply to the items that fulfill the filter rules:. Illustration 1: Example selection filter window contents. In the future, it could be extended by handling Python expressions in order to create more sophisticated filtering rules eg. The Tool Framework puts depository tools on a stack, so if one tool finishes its operation then the stack is unrolled and the previous tool is active again.

This may lead to a situation where there is no active tool and therefore no context menu accessible. The selection open hardware repository cern zoom should open hardware repository cern zoom always at the bottom of the stack, to ensure there is a context menu for user and basic mouse events handling. To make it easier to follow connections on a PCB, there should be a net highlight mode available.

In principle it should work exactly the same as the high contrast mode, but highlighting nets instead of layers the Repositoy and Shove router uses that mode. Illustration 2: Net highlighting mode. There should be a properties dialog available for all item types, same as the one currently available in Pcbnew.

The dialog should be shown after a double hzrdware on an item haardware selected from the CM. This could be displayed after hovering the mouse cursor over an item, without any clicking and replace the board statistics informations number of oppen, vias, etc. This could be reimplemented using the Observer design pattern, instead of updating the button on every update UI event such as mouse movement.

For a block of selected items, give an option open hardware repository cern zoom align one edge of every item open hardware repository cern zoom box to the edge of another item e. Another related functionality is items spread that puts parts Open Hardware Network Switch Java evenly distanced from each other alongside a chosen axis. Illustration 3: Example alignment modes for selected items. Currently one can only revert the current operation i. Tools should have an option to revert at least a few recent operations, possibly making it consistent with the default KiCad undo buffer.

This functionality is currently available in KiCad. It lets users manipulate items more precisely. To extend it, there could be hotkeys available to increase the unit oprn distance e. If selected items are of the same type, there could be some extra specific actions displayed, e. We should be able to choose any action without any mouse movement, but only using hotkeys.

The context menu is designed mainly for the new users to ease the learning curve and let them learn shortcuts. Short descriptions of menu actions should pop up, if the mouse cursor is held open hardware repository cern zoom them for a while e. Re;ository filter: allows to filter selected items by layer or type.

Illustration 4: The context menu plan. The illustration presents the concept of the new context menu. Menu entries prefixed with 'G' are shown only for groups of objects, 'S' stands for single items, 'T' for type dependent, items without any prefix are always shown. Please note that every single item is accessible by a hotkey combination, e. Page history. Delete Deletes selected items or groups of items.

This begins the movement Open Hardware Virtualization Zoom operation. Move it to the destination place. The new copy is fixed in the spot where the command was issued. Allow user to refine the selection by toggling some of the selected items by clicking them with Shift held.

Pick a reference point or item the point hardwaare will be used cfrn dragging the pasted block later. The cursor is tied to the reference point selected when copying the block. Snapping allows to place components both in the grid nodes or to connect them directly to existing items. Pressing the [tbd] key should enable linear movement mode i. Pasted vias and tracks inherit nets from the items they were placed over if there is a direct eletrical connection between the objects e.

Zoom settings Open hardware repository cern zoom zoom options are right now fully available in the context menu and hotkeys toobut they could be grouped together into one menu position that is later expanded to all options please have a look at the CM plan at the end of the document and accessible by hotkeys in a similar way to the grid settings.

Proposal of the new context menu Illustration 4: The context menu plan. Page slug Tip: You can open hardware repository cern zoom the full path for the new file. We will automatically create any missing directories. Create page.

CERN will soon submit the CERN-OHL for endorsement by the Open Source Initiative (OSI) and the Free Software Foundation (FSF). Questions about the Open Hardware Licence and Repository should be directed to Myriam Ayass (www.- @www.- ). For more details on the CERN-OHL, please visit www.- Jul 21,  · I should fork the repository on Github and add my build files and bill of materials. I'm going to calibrate the zoom with a stage micrometer and check it against 2μm Polystyrene Latex (PSL) beads. Hardware designs on this site are released under the CERN Open Hardware License Zoom is the leader in modern enterprise video communications, with an easy, reliable cloud platform for video and audio conferencing, chat, and webinars across mobile, desktop, and room systems.
