Hakology Day 15 : Blog Entry

[1005]
Wow two weeks, time flies when you’re having fun. Knuckling down again today hopefully somewhere near to completing the gqrx video. Spent some of the weekend teaching a friend python and the other half modding my retropie. After spending a few days working on it, its coming together quite nicely. Loads of classics, managed to setup dosbox and test some ports. NB. Some ports seem to FUBAR the card / os / boot. Select carefully when installing them. Once you have a good working SD card F£$%ING image it (*as regularly as possible whilst building your retropie install*) I’ve had to start from scratch a few times, once is annoying but on your fifth attempt it starts to get a little frustrating.
Right coffee and breakfast time.

Ended up having to help a friend out earlier, but back to the computing now. Looks like gqrx is even easier to setup in linux than in windows that makes a nice change.

Notes written and I think i’ve worked out how to record the linux installs. Even managed to get the RTLSDR working in vitual box, but its bit late to start recording.

Hakology – Retropie HDMI audio fix

No audio over HDMI on retropie? No problem, here’s your solution i’ve seen a few fixes on the web lots varied some were overly complicated so I decided to write up a really simple fix. Tested and working on the RPi3MB.

Boot retropie
Go to the retro pie menu
Go to the audio menu and press ‘A’
Ensure HDMI is selected, also check the mixer volume is at 100%
Save settings and return to the retropie menu
Quit emulation station
Run …
sudo nano /boot/config.txt

uncomment the following …
#hdmi_drive=2
so it looks like this …
hdmi_drive=2

also uncomment …
#hdmi_force_hotplug=1
so it looks like this …
hdmi_force_hotplug=1

Press ctrl+x to save the file.
now run …
amixer cset numid=3 2
and ..
sudo reboot

Hopefully you should now have audio over HDMI

Hakology – Retropie steam controller setup guide

Notes to accompany the following video showing you how to setup and configure the steam controller for retropie. Tested and verified as working with python 2.7 on the rpi model B and rpi3 model B.

sudo apt-get install python-pip
sudo pip install libusb1
sudo pip install enum34
git clone https://github.com/ynsta/steamcontroller.git
cd steamcontroller
sudo python setup.py install
sudo nano /etc/udev/rules.d/99-steam-controller.rules
Add these lines :
SUBSYSTEM==”usb”, ATTRS{idVendor}==”28de”, GROUP=”games”, MODE=”0660″
KERNEL==”uinput”, MODE=”0660″, GROUP=”games”, OPTIONS+=”static_node=uinput”

sudo udevadm control –reload
sudo crontab -e
@reboot /usr/local/bin/sc-xbox.py start

Hakology Day 6 : Blog Entry

[15.31]
Really late night last night, time to get the kettle on and wake up. Need to do some shopping then I think ill look at re-recording the steam controller tutorial without the animations and just do a straight forward install video, I’m thinking that’s the best plan of action. Wasted too much time on this video and want to get busy with SDR and some other bits and bobs.

Hakology Day 4 : Blog Entry

Chores done and I’m online. Going to get busy, goals for today, get steam controller working on retro pie, re-record retropie audio, and re-render using better stock footage including steps to configuring. Then if I have any time get back on the SDR work.

Steam controller working in retropie … whoot.

Written an automated installation script. Finding bash in raspbian has some unusual defult settings regarding echo. If any one knows how to get echoes to display …
[/19.23]


[20.05]
Testing and debugging script. Being a noob. Making silly mistakes. Correcting them. NTS: tput setaf 1; is a great way to set echo output in bash 🙂
[/20.05]


[20.10]
Finished …. taking a break. – Managed to brick emulationstation in the process, now have to recover script and reimage.
[/20.10]


[20.24]
Turns out if you boot the pi with a cronjob for the steam pad drivers it’ll crash emulationstation if you dont have the dongle inserted.

Random pic for the day, great tool all round esp when it comes to cabling new pc builds or finding that tiny screw you just dropped on the floor, cree LED with recharagable 18650s and adjustable focus.
