Volume Control for a Android Head Unit

I gave myself a birthday gift earlier this year.  Upgrading my truck’s cd/tape deck with something more modern.   I installed an Android Head Unit.  For less than $200 and a weekend of work, I gave my 2005 truck modern features such as bluetooth, reverse camera, gps navigation, and mpg gauges.

I have had the android head unit installed a few month now and am still really impressed.  The head unit’s speaker amplifier is a huge upgrade from what I had for sound quality before.  The radio receives stations for longer distances.  I use the bluetooth and reverse camera features daily.  The mpg gauge is done through the Torque app that was preinstalled, and it also has a nice feature of calculating fuel miles remaining.  Cool.

Mark 3 Ammo Counter

Nerf, Paintball, Prop Weapons. This is the ammo counter you want~!

il_fullxfull.1307046934_eifm


The Ammo Counter MK3 is a remix of my previous ammo counter design and is now completely reprogrammable by you with no additional tools! There are 10 clip slots in memory, you can easily switch magazine sizes with a single button press. In addition, each clip slot can be reprogrammed by you for any starting value up to 99. Each slot will remember your selected fire mode, semi-auto, full-auto, and count up.

Video tutorial: Coming Soon!

Features:
* Smallest Ammo Counter Circuit!
* Selectable Clip Sizes
* Programmable Clip Sizes (Default: 35, 25, 22, 18, 15, 12, 10, 6, 32, 99)
* Programmable Fire Types (Semi-Auto, Full-Auto, and Count Up Semi-Auto)
* Light Break Sensor Ready



Ammo Counter 2017 – New Design

This is a small preview of the new ammo counter design I am working on.  There are two buttons on the face of the circuit that will allow you to select from preset modes, or add your own!  No more hardcoded starting count values!!

More info to follow…

The finished circuit will be about the same size as my previous ammo counters.

OTA Antenna FAQs

Here are some Frequently asked questions I get about TV Antennas in my town:

  • What is the best antenna?
  • Can I go bigger?
  • Can I pick up channels from both Madison and Cedar Rapids?

What is the best antenna?

The best antenna is the one that fits your budget. Here is my handout I give folks who ask. I have it broken into three budgets. < $50 / $120 / $200
https://docs.google.com/document/d/1x113jqeepDhK4VtcKPQecNvcxV7hLQJXG0ZTiL3sqp0

Can I go bigger?

Short answer, no. Long answer, it depends but probably is not worth it. You can explore this page which describes running multiple DB8 antennas. Midway down the page you will find “Why this 16-bay antenna might not work”. Take a read through.
http://www.hdtvprimer.com/antennas/16bay.html
http://www.hdtvprimer.com/ANTENNAS/32bay.html

Can I pick up channels from both Madison and Cedar Rapids?

Again, short answer no. Long answer, maybe. Antennas like the DB8e have multiple elements that can be pointed in different directions. Aside from halving your antennas efficiency by splitting it in two, the next problem is that some of the signal picked up by Side A is then radiated out of Side B. This results in your received signal dropping by more than 50% !
If you are thinking about adding a second antenna to overcome these losses, see above “Can I go bigger?”

OTA Channel List – Aug 2017

I did a scan tonight and found FIVE new channels I wasn’t aware of. If you have an antenna, do a channel scan on your tv to find the new channels. ION, 24/7 PBS Kids, TBD TV, American Sports Network, and QVC.

Here is an updated list of stations from Madison that we can receive in Platteville~! All primary channels are broadcast in 1080i or 720p HD, with the exception of CW, all subchannels are 480i.

https://www.etsy.com/listing/523973930/mini-nespi-electronics-kit?ref=shop_home_active_2

If you already have a 3D printed case, raspberry pi, arduino, NFC reader, and all you are missing is something to tie them all together. This kit is for you!!

I can answer questions here, by PM, or email thatdecade@gmail.com

Special thanks to Joshua Kane, Jared Kirchgatter, Jason Victoria, Dave Hicks, Ruud Lok, Jeff Moore, and everyone else who helped me debug the design! This kit fixes several issues with the DaftMike’s original design: broken mosfets, non working controllers, and other assembly difficulties.

Assembly Guide is here:

Amazon Fire TV or Roku TV?

I think the Amazon Fire TV will replace my current recommendation for the Roku TV as my favorite “Over The Air” receiver. Just like the Roku TV, the Fire TV will have the ability to pause and rewind live TV.

However, Fire TV adds the ability to pull up a TV Guide. A feature I sorely miss from my cable days and I supplement with a TV Guide app on my phone.

You can checkout the features here:

Ammo Counters – Researching Competition to Push a New Generation

I have been selling ammo counters since 2009. After I made my energy sword, ammo counters were the most requested kit. Over the years, I have probably sold 200-300 kits. Back then, I easily beat out the lame old competition. However, sales dried up last year. I was busy with my EMF and NES projects so I didn’t look into it.

Today, I searched around for new competition. Oh man. Things have changed. I think I still got them beat on size and price, but I need to work on my offerings to stay competitive.

Old competition

New competition

  • Nathaniel Deal: Nerf Ammo Counters
    • Good price for what you get.
    • Offers both bare bones and complete kits. Some kits include 3d printed shells.
    • Mostly focused on nerf builds. Requires additional circuit boards that must be hidden inside your build.

MiniNES: Projector

I found an $50 micro projector on ebay that has a USB power output. The 480 resolution is plenty for all the game systems!  Fits perfectly below the MiniNES case!

No automatic alt text available.

I do get undervoltage warnings, but I should be fine as long as I have a clone image to use when my SD card goes corrupt.  Here is the link if anyone wants to take a chance on a “untested” “might be broken” “sold as-is” “no power cable included” projector
