The Borkin Button – Guide

Hi all,

Once I saw video made by ETA Prime about One-click Shortcut Key plug or on some sites its called dust proof plug. I thought, “wow that’s good :-)”. I looked to eBay and ordered me an button. They are shipping two for good price (~1$) and they are working great. I am using this button with my Retropie setup but this will work also for Raspbian.

*Disclaimer – I am not responsible for any damage you can do to your Raspberry Pi, software, or to you.*

To get it working you need cable like the one below. You just need to get rid of the ends.


Then you need the button 🙂

Then you have few options. Use soldering iron, tape the cable or use hot glue. I went for hot glue. The main and only reason was that I am still waiting for my new soldering iron.

So obviously you need hot glue gun.



1: Cut the cable to have it like on picture below. Don’t forget to do the same to both ends.


2: Bend both ends of the cable around pins on raspberry pi. (On the below picture is only an example how I did it on the Pi).


Important is to use correct pins see picture below. Third pin on GPIO header (so if you looking on your Rpi as me on the picture its third pin on bottom row) and middle pin of 3.5 mm audio jack.


3: Heat up the hot glue gun and use it on the bended ends around pins

4: Final look


6: Don’t forget to install your button 🙂


5: Install script

The original source is at I installed the script using SSH method. I am Windows user so I used Putty.

Once you are logged on (standard user name is Pi and password is Raspberry) paste this line curl | bash


Hit Enter on your keyboard and wait untill script is installed. Once it’s finished go to your Rpi and press the button (for me it didn’t worked for the first try. So I had to reglued one connection on the middle pin of 3.5 mm audio jack) Rpi should shut down it self like on my video below. If you press the button again Rpi will boot up.

Thank you Matt Borkin for the idea and script. Also Thank you ZT Group. 🙂


Overclocking RPi3 – Guide

Hi all,

*Disclaimer – I am not responsible for any damage you can do to your Raspberry Pi, software, or to you.*

finally I received the cooper heat sinks I ordered on eBay. Even though I had 4cm fan installed over the Pi I wanted to wait for the heat sinks.

Lets take a look at them installed, see below.

If you are interested in the keyboard behind RPi its Corsair Raptor K50 🙂 and cables connected to GPIO are heading to small fan. One think you should know RPi3 can’t be overclocked from Raspberry Pi setup like RPi or Rpi2. You need to modify config file on SD card.

Good start how to oc RPi3 has ETA PRIME but I found some flaws in his guide.

So I recommend to follow it only partially :-). What is important to know what OC settings will void your warranty.

Below text is from Github

!Those setting will void your warranty!

  • over_voltage greater than 6

  • force_turbo=1

  • temp_limit greater than 85

With over_voltage don’t go above 5, only if you are super crazy and want to try run Raspberry Pi on 1,45 GHz. Rising over_voltage can help with stability issues also this will raise temperature of CPU.

Forcing turbo means that CPU will always run on highest speed -> stock clock is 1,2GHz so it will run all the time on that speed. Normally CPU reducing speed if no demanding applications are running. This setting is also somewhat affecting temperature.

At last but not least temp_limit means the temp. threshold when CPU starts to throttling.

Make a backup

So first thing to do put you SD card to PC. Then in root directory there is config file make a backup :-). Then we need to modify the config file. You can open it in notepad (not recommended) or you can use Notepad++ as ETA mentioned in his video. If you are using Notepad++ go to line 43.

On that line is written #arm_freg=800. First delete this text and replace is by your OC settings. You can use my settings below, its only mild OC.

  • arm_freq=1300
  • gpu_freq=500
  • core_freq=500
  • sdram_freq=500
  • over_voltage=2

As you can see I used over_voltage=2 (no warranty void). With this setting RPi is rock stable and temp is ~40°C on idle and ~60°C  during playing N64 game. For most 2D emulators you need higher arm_freq but for more graphic intensive systems like Dreamcast or Nintendo 64 or PlayStation 1 you need higher gpu_freq. Core_freg is same as gpu_freg so set it on the same speed. 

Save config file and return SD card back to RPi and boot up. Connect to your RPi through SSH using PuTy (How to use PuTy – User name is pi and password raspberry.

To see temperature use command vcgencmd measure_temp

Ok that’s it. Go and play with it more 🙂 try different settings play games etc, its up to you. Please bear in mind that you do it at your risk…

See you next time!

Song of the week 16 – take two

Hi all,

there is already the Song of the week 16 but I need to make another post about the Song of the week 16. I am currently watching Mobile Suit Gundam 00, in Japanese Kidou Senshi Gundam 00. I am almost finishing second season which is also the last season :-).

But why I am writing about Gundam in the Song of the week? In episode 14 of the second season, there is moment when Marina singing with the Katharon orphans. They were singing about world peace, about world unity.

So enjoy this great song.


Thank you and see you next time!

Sela the theme that I am using

Hi all,

this will be something like confession 🙂 about theme I am using for my blog. The theme name is Sela as I stated in post title. Sela is simple theme obviously, just look at my blog :-). But its good thing simplicity is some times more then convoluted theme with lots of special effects.

I am not saying that I will stick with Sela forever but for past two years Sela was best. I didn’t find any other theme that would fulfill my expectations about clean simple style. Funny thing that Sela on the looks completely different from my blog. I like that you can modify most of the features of the WordPress themes.


See, my blog differs a lot from original Sela :-).

Thank you and see you next time!

Song of the week 16

Hi all,

what I can say. Don’t make contracts with evil man in stuite :-). At least that was my feeling from video clip of band Ultravox.

Hymn is the name of the song. I just love 80’s :-). As I said above, the video clip is dark?! Not sure why though…:-) the song is not dark at all.

see you next week.

Great story not a click bait

Hi all,

My mom asked me if I can share link to writers competition where she is participating. Its with several rounds. Now she is between finalists. For the final the task was to write a script for TV series. Mom wrote about family stories well our family stories:-).

This is the story she wrote

And sorry its a Czech competition so stories are also in that language.  But I also have Czech readers… 🙂
