Portable Console Emulator using a Raspberry Pi

Here’s a couple pictures from my last project:  tablet-based teleprompter with 15mm support rods and a quick disconnect camera system.  It turned out very well.  One of these days I’ll post up some more detail.

But that project’s over and my shop is missing me.  This time I’m getting back to electronics.  Lately I’ve been playing the old NES games.  Well, when I say playing, I mean with my original NES.  I left a cartridge in the console the last time I played it and all of the pins got stressed, resulting in the blinking display.  This is typical when the pins connecting to the cartridge don’t make a good connection.  Bending them back was an easy fix, and didn’t even require the removal of the security chip.

Anyways, now I’m trying to make a portable system based on a Raspberry Pi.  Having installed the RetroPie distribution, running NES/SNES/Genesis/etc. emulators are a breeze.  I bought a few other components to make sure everything would work, and then started designing.

Portable Console v3 - 1Portable Console v3 - 2

Here’s what I’ve come up with.  I went through several revisions, trying to maximize space and portability.  At the same time, I tried to keep ergonomics in mind.  The size is a bit chunky, but feels good in the hand so far.  The enclosure is made of two pieces of polypropylene.  Originally I wanted it all milled out of solid aluminum.  Not wanting to spend 500 hrs making billions of passes milling, I chickened out for something much easier to machine (set RPMs low and make heavy cuts).

The parts I’m using are, mostly, shown below:  a Raspberry Pi, a 12V-5V switching regulator from eBay, a 4.3″ TFT car monitor from Amazon, a 12V LiPo battery with integrated charging and power switch components from eBay, and the little silicon pads from a Logitech Gravis Gamepad Pro that doesn’t work.  Oh, and a Teensy v3 to make the gamepad portion.

Since I’m splitting up the buttons from a traditional gamepad with the monitor in the middle, I needed some custom PCBs.  Gamepads work by closing circuits to ground via silicon pads with bits of carbon in it.  I could use some pushbuttons, but wanted to retain the nice action of a gamepad button.  Once I got the dimensions and button positions from Inventor, I made the PCB layout in DipTrace.  Then I used the tried and true laser toner, copper clad PC board, and ferric chloride PCB solution.  It took a few tries, but I like the results.

image  image

The 4.3″ TFT monitor is a great deal for $18.  I just need to make some changes to get it how I wanted.  First was to remove the case and hardwire the power to the battery and to the regulator.  Next I needed to remove the pushbuttons on the back of the monitor.  Eventually I’d like to control them via my Teensy microcontroller because they bring up the menu for setting things like brightness, etc.

image  image

When I first got the regulator I was a bit suspicious since it looked like there was a big glob of solder bridging a couple nodes.  Metering it all out it appears OK.

image  image

 

I then hardwired power and NTSC video directly to the Raspberry Pi.  The main regulator pads were the best place to supply 5V and bypass the USB port.

image  image

Lastly I started fabricating the front of the enclosure.  I’ve got about 8 hrs into it now and haven’t made any mistakes – yay!  Unfortunately I ran out of polypropylene and had to put in a new order.  In the meantime, I am going to make the buttons.  Well, that’s all for now…

  15. وکیل ملکی

    November 8, 2020 at 6:27 am

    حرفه‌ای ترین و بهترین وکیل ملکی تهران کیست؟ وکیل پایه یک امور اراضی و املاک چه خصوصیاتی باید داشته باشد؟ وکیل ملک خبره در چه پرونده‌هایی تبحر و تجربه دارد؟ متداول‌ترین دعاوی ملکی کدام‌ها هستند؟ پاسخ دقیق این سوالات و اطلاعات مهمی از این دست را در این مقاله بصورت کامل شرح داده‌ایم که در ادامه مطالعه میفرمائید.
    دعاوی ملکی چیست ؟
    وکیل ملکی به وکیلی گفته می شود که در حوزه دعاوی ملکی تخصص دارد. دعاوی ملکی عنوانی برای مجموعه ای از دعاوی است که به نوعی به موضوع ارتباط بین اموال غیر منقول و انسان مربوط می شوند. اموال غیر منقول به اموالی گفته می شوند که امکان جابجایی و نقل مکان ندارند و در یک تقسیم بندی شامل املاک و اراضی می باشند و در تقسیم بندی دیگر می توان اراضی را به اراضی داخل محدوده شهری و خارج محدوده شهری تقسیم بندی کرد و در تقسیمی دیگری املاک را می توان به املاک تجاری و مسکونی منفک کرد لذا دعاوی مختلفی در رابطه با تقسیم فوق مطرح می شود که تمام این دعاوی در حوزه کاری وکیل ملکی است .
    خصوصیات یک وکیل ملکی با تجربه
    – یکی از خصوصیات بارز یک وکیل ملکی خوب و مجرب، میزان تجربه اوست.

    علیرغم آنکه تمام وکلای دادگستری امکان بررسی و قبول وکالت در تمامی پروندهای ثبتی، کیفری، حقوقی، ملکی و خانواده را دارند، اما تجربه یک وکیل ملکی خبره در زمینه امور مرتبط با املاک و اراضی باعث می شود تا بتواند با درصد موفقیت بالاتری در تمامی دعاوی ملکی قبول وکالت کند.

    – از دیگر خصوصیات یک وکیل ملکی مجرب دانش حقوقی و تسلط علمی او در زمینه های مختلف حقوقی،کیفری و ثبتی امور املاک، اراضی و مستغلات است و باید ضمن آشنایی با قوانین و مقررات مربوطه، همانطور که در بالا گفته شد با آراء وحدت رویه دیوان عالی کشور، آراء وحدت رویه دیوان عدالت اداری، نظریات مشورتی اداره حقوقی قوه قضاییه، نظریات اساتید برجسته علم حقوق و دکترین و همچنین رویه مرسوم محاکم و دادگاه های کشور نیز آشنایی کافی داشته باشد.
    خصوصیات وکیل خوب ملکی
    یکی از خصوصیات وکیل خوب این است که قبل از حضور در جلسه ی رسیدگی و دفاع از موکل با مطالعه پرونده ، اطلاعات کامل از موضوع پرونده ، دلایل و مدارک مستند پرونده را بدست آورد . همچنین وکیل خوب کسی است که در مقابل موکل خود احساس مسئولیت کند و پاسخگوی موکل خود باشد . هر چند که وکالت تعهد به وسیله است و وکیل در رسیدن به نتیجه قانوناً مسئولیتی ندارد .
    وکیل ملکی کیست و چه موقع باید به سراغ یک وکیل ملکی برویم؟

    وکیل ملکی به وکیلی گفته می شود که با توجه به تجربه و تخصص و اشرافی که در زمینه پرونده های ملکی دارد تخصصا به وکالت دعاوی و پرونده های ملکی می پردازد. شاید اینجا سوالی پیش بیاید مبنی بر اینکه وکیل ملکی چه ویژگی های اختصاصی باید داشته باشد که ممکن است سایر وکلا از آن بی بهره باشند. در پاسخ به این سوال می توان گفت که یکی از خصوصیات مهم وکیل ملکی بهره مندی او از دانش به روز در باب قوانین جدید و قدیم ملکی و اشراف و تسلطش به آرای وحدت رویه و نظرات اساتید مربوطه در علم فقه و حقوق املاک می باشد. وکیل ملکی پس از اختصاص زمان کافی جهت خواندن پرونده و مصاحبه و جلسات متعدد که با موکلش برگزار می کند، باید بتواند بهترین استراتژی پیشبرد موفق دعوی ملکی را در جهت حداکثر کردن امکان برد در پرونده موکل سازمان دهی کند.

    از دیگر مشخصات و ویژگیهای منحصر به فرد وکیل ملکی این است که علاوه بر دارا بودن تمامی موارد بالا در نگارش لایحه به صورت ماهرانه تمامی موارد مرتبط با پرونده را ذکر کرده و به جهت داشتن فن و قدرت بیان و تسلط و اشرافش به پرونده ، در حضور قاضی مقتدرانه از حقوق موکلش دفاع نماید.
    بهترین وکیل ملکی
    دریافت بهترین وکیل ملکی و همچنین مهمتر از آن، تنظیم نمودن قراردادهای ملکی توسط وکیل پایه یک دادگستری قراردادهای ملکی می تواند امکان ایجاد اختلافات ما بین طرفین معاملاه را تا میزان قابل توحهی کاهش دهد. البته گاها پیش می آید که با وجود وکیل متخصص در زمینه قراردادهای ملکی باز هم در اجرای قرارداد و یا تفسیر معامله بین طرفین اختلافاتی پدید آید. در این موارد برای حل اختلافات، داوری در قراردادهای ملک و املاک و یا مراجعه به دادگاه های دادگستری و یا حسب مورد و یا شورای حل اختلاف نیاز است.
    حیطه فعالیت وکیل ملکی
    توجه کنید که وکیل دعاوی ملکی اگر چه که می تواند در دیگر دعاوی نظیر دعاوی خانوادگی و … نیز وکالت افراد را به عهده بگیرد اما ترجیح داده است تا به صورت تخصصی عمل کرده و بر روی دعاوی ملکی تمرکز نماید تا بتواند دعاوی از این دست را به درستی و در تمام جوانب شناخته و بررسی نماید.

    بنابراین از جمله دعاوی حقوقی و کیفری که وکیل ملکی در آن ها مشارکت کرده و سعی در حل آن ها دارد می توان به انواع زیر اشاره نمود:

    تنظیم سند رسمی
    خلع ید
    کلاهبرداری
    تعدیل اجاره بها
    مطالبه اجرت المثل ایام تصرف
    ابطال قرارداد اجاره
    تقسیم املاک مشاع
    تخلیه املاک استیجاری
    اخذ پایانکار
    تائید فسخ معامله
    تصرف عدوانی
    رفع مزاحم تاز ملک
    الزام به تحویل مبیع
    جعل سند
    انتقال یا فروش مال غیر
    ممانعت از حق
    مطالبه وجه التزام قراردادی
    افراز ملک
    تعریف ملک

    برابر ماده 11 قانون مدنی اموال به دو بخش منقول و غیر منقول تقسیم می شوند ، اموال غیر منقول به اموالی گفته می شود که انتقال آنها از محلی به محل دیگر امکان پذیر نباشد ؛ با این تعریف به سادگی مشخص است که املاک در زمره اموال غیر منقول قرار دارند .

    در عرف و جامعه از ملک تحت عنوان دارایی نیز نام برده می شود مالکیت نسبت به اموال به صورت مفروز و مشاعی است ، ملک مفروز به ملکی گفته می شود که تنها یک مالک داشته باشد و ملک مشاعی نیز به ملکی گفته می شود که حداقل دو مالک داشته باشد در آپارتمان ها مالکیت ترکیبی از مفروز و مشاع است بدین نحو که مالکیت در قسمت های اختصاصی مثل داخل واحد به صورت مفروز و در قسمت های عمومی همانند راه پله ها و حیاط به صورت مشاع می باشد که از این قسمت ها نیز تحت عنوان مشاعات نام برده می شود .

    نقش وکیل ملکی
    با توجه به پیچیدگی دعاوی اموال غیر منقول و حساسیت بالا اینگونه دعاوی(با توجه به قیمت فزاینده املاک) و مشابهت هایی که با هم و بعضا با دعاوی کیفری پیدا خواهند کرد و لزوم پیگیری تخصصی این دعاوی به دلیل بی تجربه بودن موکل، ارجح است طرح و دفاع از اینگونه دعاوی به وکیل ملکی مجرب سپرده شود زیرا فقط یک وکیل میداند که چه زمانی میتواند دعوی تصرف عدوانی حقوقی مطرح کند یا اینکه در چه دعاوی می تواند الزام به تنظیم بخواهد.
