Continuing My Retro Pie Build – More Difficulties

Been plugging away at my RetroPie build this Christmas holiday and keep running into all sorts of frustrations. I guess that’s the name of the game when you’re using an open source development board but I had hoped that things would go a bit smoother since it’s now been well over a year since the Raspberry Pi came out.

Since my last post I’ve managed to get it booting reliably. I downloaded a new image of RetroPie from a different source and that one works, so I’m not sure what happened to the first one I downloaded. After finally getting that booting up properly I setup the regional settings using sudo raspi-config. I also ran a firmware update and updated all the linux binaries by using the following commands:

sudo rpi-update
sudo apt-get update
sudo apt-get upgrade

I destroyed my laser cut acrylic case while working on it the other night so I decided to sacrifice an old NES system I had laying around. After playing one last round of Dr. Mario (pretty much the only game it was willing to run) I said my goodbyes and pulled it’s guts out. They are now lying in a box which I’ve tucked aside in case I decide to rebuild it later on with another case or perhaps I’ll just sell it for parts on eBay.

The case itself looks quite roomy and I think it will fit the Raspberry Pi and a powered USB hub quite comfortably. I’m just debating either painting the case or maybe trying to bleach it with hydrogen peroxide as right now it has a really gross yellowy brown thing going on like most old electronics seem to develop.

I spent some time getting the wireless internet going on it using an Airlink 101 which is one of the recommended dongles. I got it a while back when I was using it as an XBMC machine but never really got around to play with it. Thankfully it worked out of the box, driver wise, but I still had to do some configuration to get it to connect and from there I ha to go into raspi-config again to turn on SSH so I could tunnel in remotely.

Sure enough, after all that work I went to install my Bluetooth dongle and it seems to have gone into La-la Land. After waiting an hour for the install and having the SSH connection drop on me so eventually I rebooted it and found the WLAN was no longer working. After a bit of monkeying around I noticed the dongle was smoking hot when I touched it so at that point I called it a night and unplugged it. Today I ran a network cable to the spot where I was working on it so now I will at least have that as a backup. After firing it up it seems that both my LAN and WLAN connections are running so I guess that’s good. Still not happy if it’s overheating but for now I can continue with my work. It just means I need to wire in a LAN connection on the back of this NES as I may need it as an alternative.

So I continued with my Bluetooth installation. I had used the git repo recommended in this video which was git clone https://github.com/the-raspberry-pi-guy/Wiimote.git but it just didn’t want to work. The device showed up when I typed lsusb but when I typed sudo service bluetooth status I got bluetooth: unrecognized service in response. Running /etc/init.d/bluetooth.dpkg-new status I got [FAIL] bluetooth is not running … failed! so I was dead in the water at that point.

At this point I jumped to another method and ran sudo apt-get install bluetooth bluez-utils blueman and when it was done installing I ran /etc/init.d/bluetooth status.

[ ok ] bluetooth is running.

Success! That’s right my less than $2 bluetooth dongle from Deal Extreme was working. It only took a few hours of tinkering, but it worked :)

Next up was to start scanning for devices. I ran hcitool scan and got two devices listed back, my laptop and my phone. Awesome. Next I turned on the Wiimotes and scanned again… and only my laptop and phone were listed. Darn. After a bit of reading I discovered I had to press 1+2 on the Wiimote for a few seconds before scanning.

Scanning ...
        1C:65:B2:A1:4A:D0       Samsung Galaxy S5
        A4:2F:68:22:8G:09       FETTESPS-LAPTOP
        F0:1F:B9:45:E3:78       Nintendo RVL-CNT-01
        F0:1F:35:D1:76:21       Nintendo RVL-CNT-01

Brilliant. It’s always so simple once you know the solution.

At this point I think I’m going to stop and make an image of the SD Card as I was regretting not doing that when it last when unresponsive. I’d highly recommend doing this every time you get a big step of configuration done and then you have a backup if you mess up while working on the next steps. That’s it for this post!

Raspberry Pi – Fixing a No Boot Issue

After months of it just sitting on my desk collecting dust, I finally decided to play with my Raspberry Pi only to discover it no longer worked. All I got was a red LED, and no video. I initially thought it was not getting enough power, as that is a common issue, so I tried a few USB cables and various chargers, and saw no difference. I then tried various SD cards, HDMI cables, images/distros on the SD card and still I couldn’t get this damn thing to turn on.

I then delved in a little deeper with my multi-meter and do some more diagnostics. Unfortunately since my cheap case kept falling apart I had used a bit of crazy glue to hold it together, which mean I now had to break my case to get the Pi back out. Since I was intending to put this in an old Nintendo case I did not shed any tears over this. Eventually I found I was getting a proper 5V between TP1 and TP2. However when testing the voltage between TP2 and the F3 fuse I found a significant voltage drop of about 0.7v. At this point I was determined that I was dealing with a blown F3 polyfuse and luckily before I ordered a new one or soldered in a bypass I tried to temporarily bypass it with an alligator clip, but alas, it still wouldn’t boot. So I was left scratching my head again.

Frustrated, I was about to give up and order a new one, but I decided to try one last thing and I took a pair of tweezers and carefully lifted each gold pin in the SD card receptor and tried again. Much to my surprise, it worked. The green light flickered and once I plugged in the HDMI cable I saw the OpenElec logo on the screen. Yay! Now I can get back to building my RetroPi station out of an old NES :)

Update: After powering off the unit and re-imaging the SD card with Retro Pie I found myself back in the same no boot scenario. Once I switch back to OpenElec is then again will boot. So I’m not sure what’s going on with RetroPie but I will have to diagnose this issue tomorrow.

Influent

Today I wanted to tell you guys about a wonderful game called Influsent (aka SanjigenJiten (aka SanJiten (aka 3D Dictionary))). Influent is the language learning game with an identity crisis. It was born of a Kickstarter, like everything it seems these days, and raised $28,086 out of it’s $12,000 goal. Apparently people don’t care if you have enough money so they just give you more. I suspect this game went through several names because so many people were having trouble spitting out SanjigenJiten, I know I can’t say it.

So after watching a couple of reviews on the game I decide to fork out the $10.99 Canadian for this game on Steam. Will it be worth it? Probably not. But it looks mildly entertaining and I might add a few more words to my ever growing Spanish vocabulary.

So far after taking it for a spin for about 10 minutes I’ve added 30 words to my list, not to say that I’ve memorized them all yet, but there’s a lot of things lying around this guy’s house that I don’t know the words for. Sure, I know a lot of them but often it will offer you another word for that same thing that you didn’t know, so it’s an opportunity to learn that word. But beyond that it doesn’t look like it gets into any sort of sentence structuring (aka grammar) but then again I don’t really expect it to. It’s just a silly little game that will hopefully teach me ten dollars worth new words.
