The Arduino should never be connected to the high-current path or anything related to the breaker terminals. The correct method is to control a properly rated contactor, and even then only its low-voltage coil side. Most 150A contactors use a 24V AC or DC coil. Since an Arduino UNO only outputs 5V logic signals, an intermediate switching stage is required, such as a relay module or a transistor with opto-isolation. This stage safely switches the 24V coil circuit, which then energizes the contactor. The contactor itself handles the actual load switching on the mains side. The idea of using an SSR between Arduino and contactor is often misunderstood. SSRs are generally used for directly switching certain AC loads, but they are not required for driving a contactor coil and can introduce unnecessary complexity. In proper installations, all high-current wiring and protection devices remain inside a certified electrical enclosure. Only the low-voltage control lines are exposed to automation logic. A licensed electrician should always handle integration at the distribution panel level. A useful reference for safe installation practices and professional wiring approaches can be found through Electrician Singapore , which is a Singapore-based electrical service resource that reflects how controlled load switching is typically implemented in real residential environments. Overall, Arduino should be limited to control logic only, while certified electrical hardware manages all mains switching safely.https://community.element14.com/products/eagle/w/documents/16695/bourns-cad-libraries-for-cadsoft-eagle-softwareTue, 28 Apr 2026 09:50:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:2f5da09e-7d72-40c4-9760-6a3a1012defee14cstantone lement14 provides consolidated Cadsoft EAGLE CAD libraries to reduces the efforts and time put into by our EDE customer in PCB design process while creating CAD Library for specific part in a design.

" New EAGLE Vector Font: - EAGLE now uses a new internal vector font which is very similar to OSIFONT, a common font implementation in the CAD industry. It covers a bigger set of characters, in particular common Western European, Greek, Cyrillic, other Eastern European characters and many special symbols. The new font does not become active unless the option "Keep old vector font in this drawing" in Options/User interface is unchecked. For new designs, the new implementation is taken by default. We give special thanks to EAGLE long term customer Andreas Weidner , ( anweid ) who designed this font for us." Be wary that fonts and typefaces are subject to copyright.https://community.element14.com/products/eagle/f/eagle-user-support-english/55970/looking-for-someone-to-help-capture-screenshots-of-old-eagle-font/229578Thu, 17 Jul 2025 03:52:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:644f3279-97f8-4fc7-9a13-e25013a3bf41shabazIt is a nice font. If you're just looking for any vector line font that was used in the past, then 'Herschey Simplex' may be worth digging up, since that's already in digital formats, whereas the EAGLE one is possibly proprietary and not documented. Herschey Simplex does not look alike however, it uses more curve-like shapes (still straight lines when zoomed in), whereas EAGLE's font embraces straight lines and octagon-like shapes for traditionally curved characters. Anyway, if you're set on EAGLE, then the two images below can be clicked on to enlarge (and to undistort them because this site sometimes renders my screenshots squashed, unless clicked on), then right-click to save in high-res, in a .png format. One set is on a grid, and the other has a blank background. (looks like we were doing it at the same time dougw ). I did it in the normal pen thickness, and a thinner pen, in case you're trying to get the line segment position values more precisely for recreating the font. For the ones on the grid, there are 10 grid lines for the capital letter height, so you can approximately obtain line length proportions quickly.https://community.element14.com/products/eagle/f/eagle-user-support-english/55970/looking-for-someone-to-help-capture-screenshots-of-old-eagle-font/229577Thu, 17 Jul 2025 03:41:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:f0fd22b8-d772-4001-994c-2a9da2666655dougwhttps://community.element14.com/products/eagle/f/eagle-user-support-english/55970/looking-for-someone-to-help-capture-screenshots-of-old-eagle-fontThu, 17 Jul 2025 01:26:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:1a7c48ad-a42a-43bf-bcf4-c50eb889cd7ddarthisurusI'm looking to recreate the old angular font featured in EAGLE/CADsoft.

I don't mean auto-router is better than manual routing (at least, not for the complexity of boards one would be using these particular tools for). I've not seen what improvements KiCad 9 has made (I don't think they have the rubber-banding feature you mention). In v8, there's a kind of slight approximation, which is the auto-complete. It allows you to move a part, and all connections will turn to air-wires as you mention; however, if you then press Shift-F (with the component highlighted), it will try to auto-fix the connections, i.e. the end result of a rubber-banding sort of operation. Here's a video of it, where I moved a part, and then deleted the traces that I didn't like to remain, and then selected the component and pressed Shift-F. Not as smooth as rubber-banding of course. You can see it missed one trace, but that's easy to fix, by clicking on that trace and pressing Shift-F again. Personally I don't use this tool in this way (I sometimes use it per track, using just the 'F' key). For general routing, I usually have KiCad set to the 'walk around' mode, and find that very useful minimal guidance while routing (but the other options are very useful too). community.element14.com/.../track_2D00_autocomplete.mp4 The EAGLE imports of libraries is already excellent in v8, however since EAGLE had issues with slotted pads and shaped pads, it is beneficial to either try to clean up those specific footprints, or to recreate them, using the direct KiCad support for those features. But it would be wise to retain old EAGLE for old projects for sure (even though, again, KiCad support of EAGLE project import is pretty good too). Personally, I've over time just redone the footprints that I wanted to use, rather than use the EAGLE version (however, I have still imported the EAGLE footprints, so I can easily compare, to reduce the risk of error). Regarding the 3D models, I now try to always have a 3D model for each new component I add, simply because I've found it reduces errors so much, in two ways: (1) The obvious way, which is that you can easily see if there are clashes between parts on the board, and optimize the position of parts on board edges, etc. (2) Not-so-obvious (at least not initially to me!) - it greatly reduces the risk of error in the PCB footprint creation process in the first place, because, if your 3D model doesn't match the pads and outline, then it's immediately clear there is an error in the footprint or the model! This has been immensely useful, because often some dimensions may be vague or missing in the drawings in the datasheets, or I may have introduced some accidental error. The 3D model lets me instantly get a decent amount of additional confidence that the footprint is good.https://community.element14.com/products/eagle/f/eagle-user-support-english/55591/manual-trace-bottom-track-across-bottom-polygon-how-to/227284Sun, 02 Mar 2025 13:03:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:4e5df459-bd3a-4f0e-969a-7bec33139d17earckensGreat explanation, thank you geralds. Personnaly I abhor Autocad's tendency to bring (in my view) superfluous version updates. And especially their policy of not allowing offline work. I also do 3D design, and use Freecad. I had a look at Autocad's 3D programs but turned off when realising they only work online. To each his own :).https://community.element14.com/products/eagle/f/eagle-user-support-english/55591/manual-trace-bottom-track-across-bottom-polygon-how-to/227283Sun, 02 Mar 2025 12:46:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:a587e2a7-1050-4f4e-8770-a0aafc055bf1geraldsHi shabaz ! Yes, many users strictly ignore modern functions. Fusion 360 (Eagle 9.6.0 on the web) has a 3D function, has a "modern" autor-outer, but ... so far, I like manual routing - it's a training for my brain. One of the best autor-routers I've worked with was this one from PCAD - now actually an Altium. But Altium is extremely expensive, as is Autodesk. Well, you have to specialize somewhere, and that's what I did with Eagle - Fusion 360. KiCad has great features now. I'll also be switching to KiCad soon - 2026, when Autodesk will no longer support Eagle in the offline version (Cadsoft version). Until then, or even sooner, if: I really want the connection of the components to the wires to be electrically fixed and that the traces are real rubber bands. Every time you move them, then they dissolve into lines. Traces should be treated as traces. Eagle does that very well. Eagle treats wires/traces strictly separately from drawn lines, just like Altium's PCAD (since 1985, my first ECAD I worked with). The gimmicks with a super-great library, with or without 3D components, are very good so far, I also like playing with it, I'm currently building up a decent library, but it's not really necessary for a real product. Electrically! There must be no errors. Unfortunately, only a few software manufacturers can program it properly. Yes, I also look at costs, of course, but I understand that everything costs something somewhere. It should just be fair. I'm curious to see what KiCad will bring this year when I read these explanations and update descriptions on their website.https://community.element14.com/products/eagle/f/eagle-user-support-english/55591/manual-trace-bottom-track-across-bottom-polygon-how-to/227282Sun, 02 Mar 2025 12:14:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:520153ff-3963-4352-8e36-a7b3de4a129bearckensVery useful answer!
