Aleksejs Ierakstīts Septembris 4, 2012 Share Ierakstīts Septembris 4, 2012 Sveiki! Dažreiz internetā ieraugu paziņojumus par to, ka izsludināts kāds konkurss elektronikas entuziastiem. Kaut arī pats nevaru/negribu/nespēju/esmu_par_dumju tajos piedalīties, tomēr domāju, ka šeit ir kādi, kuriem tas varētu arī interesēt. Tātad - pēdējais, ko esmu redzējis: Open 7400 Logic Competition The Open 7400 Logic Competition brings awareness to open hardware and software, and fosters understanding of the building blocks of modern integrated circuits. What can you build with logic chips? Build a kooky, intriguing, or over-complicated project that makes use of a discrete logic chip and you could score some of the sponsor swag below. Judging criteria and categories Entries will be judged for: Hilarity Originality. A smart new design that inspires Documentation. Schematics, theory, pictures and/or video (Mis)use of 7400 logic. Show us what 7400 logic was (never) meant to do Technical prowess Build quality Imagination and creativity Rules Any electronic circuit can be entered, but judges will favor designs where discrete logic chips are a major component. All discrete logic families are acceptable, including 7400, 4000, etc. Original entries will score you the most points. Please don’t copy existing designs from the internet or entries from last year. Submit as many projects as you want, but please submit each separately. Good documentation is a must. Use a video, pictures, schematics, etc to document the project and show it in action. Project files must be released under an open source license. Closed source software or hardware is allowed, but the design of the logic portion should be fully disclosed and redistributable. We want to show off your project, and other websites will too. You agree to allow any part of your submission to be republished here and at other media outlets. All rules, categories and decisions are subject to change at any time. We’ll do our best to let you know about any changes and why they were made. Entries must be received by October 31, 2012, 6AM GMT. Winners will be announced on this webpage by November 10, 2012. See the list of winners from last year. P.S.

JDat Septembris 5, 2012 Share Septembris 5, 2012 Nepareizi. Kāds skatās pacifismu iekš Star Trek seriāliem, bet nepalīdz. Gribētu arī kādu komentāriņu no forumiešiem par manā linkā ielikto konstrukciju ar 7400. Vēlams lai komentārs nebūtu no D_L. Ja D_L izteiksies tad nebūs interesanti.

osscar Septembris 5, 2012 Share Septembris 5, 2012 nu ko tur komentēt - pa lielam sviests. bet tikpat labi tauta izmanto 555 mikreni kā D klases spastūzi vai LM317 regulatoru kā A klases ampu,,,, Link to comment Share on other sites More sharing options...
JDat Septembris 5, 2012 Share Septembris 5, 2012 Par to ka uz 555 var taisīt PWM, tas tā kā zināms, bet D klases pastiprinātājs? Tas ir kaut kas jauns indigo pasaulē. Laikam tomēr neošņākos gar sviestiem tik daudz. LM317, tā jau sen zināma šīze. Link to comment Share on other sites More sharing options...
Aleksejs Septembris 5, 2012 Author Share Septembris 5, 2012 Kas tur ko izteikties... interesantākā lieta, manuprāt: The reason why it works is that, unknown to many, inside the chip, there’s a zener diode that runs between the chip’s GND pin and to all of it’s input pins. @JDat 555 class D amplifier Link to comment Share on other sites More sharing options...
