Doh!

This was meant to be a one-off, lets just have some fun kind of project. I was once told if you don’t learn something new everyday it just wasn’t a day. And I did learn in my eagerness for some quick video gaming gratification. 

I had been trolling through my parts box and thinking of a fun project to work on. Then I remembered two things. First was the ATTiny85 video games. I always have ATTinys laying around so this would be great. I checked the BOM and I had everything save the PCB boards and they are available on OSHPark. I even had a spare OLED screen in my display box. COOL. And, and, a way back I had an online bump in with Drew of OSHPark and he had sent me a gift certificate for boards. Excellent. I quickly put in my order and it was under $4.00 so still plenty left on the coupon to get my first PCB designed board done. 

I placed the order and forgot about it for a while. After all of the slow boat from China orders I tend to forget about things once I order them, I can’t stand being obsessive over something that is just going to take its time. Anyhow, low and behold one day when I get home from work there is a little package from OSHPark. I quickly get into it and see the 3 pretty purple boards and my OSHPark sticker for the collection, just waiting for a quick trim with the Dremmel and then get populated.

When I wasn’t waiting for the boards I took the time to program a ATTiny85 and breadboard it up with the screen. I wanted to make sure the big parts were ready and working for when the boards showed up. I almost wired up buttons, but it was about 2:00am and it was time for some slumber.

I was giddy at work just itching to get home and put all of the parts together and play some Tetris. And to be honest it has been quite a while since I have played it. Alright already, all of the parts are laid out and the iron is hot.

There I go. It took about an hour to get it all soldered up. I was trying to be extra nice, and neat. While my soldering skills are markedly better than they were a year ago, practice makes perfect and I am still working towards that goal. Once it is done the big moment, time to slide in the battery. I rummage in the battery drawer and pull out a CR2032 and pop it in. And nothing. 

Really, nothing. Take it out and make sure I have positive facing up, yup. One more try and nothing. I pulled out my multimeter and check the battery 2.1V. Doesn’t that figure and I wait another day as it is again about 1:30am’ish (I work second shift so tend to have late hours in the studio). 

I grab a two pack early the next morning and try it again. NOTHING! Well shit and shoved in it Wilbur I am getting a little annoyed by this time. I pull out my meter again and start checking continuity and don’t find any issues. I put the battery back in and start checking my voltages. All the pins have power and reading at the correct levels. WTH?

I sit down and start doing a little web surfing while keeping a picture of the Pocket Tetris on my screen. What could be wrong? Well it is a funny little story about CAREFULLY checking what pins go where and which pins you have there after staring at one’s problem for a good long while. There was a dope slap and a DOH! involved when I saw it.

Now this simple, fun, quickie project will have to wait a little while longer. That was my only spare screen and I don’t have a solder sucker (yet). So while another slow boat makes its way here with new screens, with the CORRECT pinouts, and a solder sucker I have other projects to move onto. New high scores will have to wait for another day. 

Raspberry Pi Arcade Project

Next on the project list is a Raspberry Pi arcade system. Once again we are starting small with as much stuff as we could from around the Studio. I already had a Pi 3, monitor, keyboard, no controllers (ordered those), and for kicks I got another of the Pi Zero Audio DACs for sound. I will have a speaker leftover from the pool-USB-Streaming-Audio project so it works out well. 

We loaded it up with RetroPie and I have to say I am quite impressed. The software works quite well and while it is easy to setup there are quite a few options to check out later on. Right now the most imperative thing to my son was getting it up and playing on the screen today.

Someone has donated some Xbox controllers for the system. We are still going to make some kind of case for it. At this point I am not sure if it will be an all-in-one or keep the console separate from the monitor. Once again I will have to let this one stew and see what comes of it. 

I want to start to put together a real arcade style box for the controls, joysticks and buttons for 2 players while keeping the USB controllers for other games. I doubt I will go the standup route, but I never know where projects take me after a while. My big must have for this phase of the project is a Tempest spinner controller. Tempest has to be one of my all time favorite games! And it really isn’t the same trying to play it with a keyboard or mouse, and most paddle are wheezy at best. I have started digging into them. 

So let me share with you the links and information I have found on making a spinner. I am looking forward to scrounging and finding the right pile of parts for this one. 

BREAKING NEWS – I just found this site today and it seems to have one great manual for making a spinner. 

There is one place I found where you can purchase one, theirs is called the SpinTrak, they are pricey. Maybe when I make my standalone Tempest game. 

I found this setup which is pretty cool. And making a controller was my original and still my preferred idea. 

Below are some of the other links I have found dealing with DIY spinners. 

Made from an old VCR head.

Another excellent example made from the what-the-lab-will-surrender category

A spinner made right inside the mouse. Pretty neat concept.

Blast from my past

I used to LOVE this game! It is one of the original Mac games I can remember. For a while they were few and far between.
