The sound the little RF Receiver made every time I pressed the remote was really bugging me, so before going to bed I decide to remove the little ‘siren’.

I tried searching the internet and even found the new support forum for the product, but nobody seemed to know if the bleep could be turned off programatically, so I decide to simply remove it.

The siren or buzzer is located in toward center of the board

I used a de-soldering tool to suck out the solder

I soldered in some wires just in case I need to re-attach the siren later to change the RF code. Sorry it’s such a bad picture

Much better 🙂

02/10/08 Update – Here’s the board with an LED added in place of the buzzer (don’t forget to add a resistor on the positive leg. Resistor size will vary and depends on your LED. Source voltage should be 12V, so as an example given a 3.3V LED with a forward current of 20mA, you’d use a 470 ohms resistor but something bigger will work too, but the LED will be a bit dimmer.)

I just upgraded the gallery software and now my thumbnails are all screwed up. Apologies while I go back and fix each post 🙁

My CF3 Sound Board arrived today as well as the 5″ horn speaker from Parts Express

Damn is this thing loud or what? Gerard had talked me into getting a horn speaker and he was right, it’s perfect. I’m going to have fun blasting this thing around C4.

The only issue is ACS were out of stock of the add on CF3 Contact Sense 24 board, so I’m limited only being able to trigger two banks of sounds for now.

Got my pass today for Celebration 4 🙂

It only feels like last week that I was posting something similar about C3.

They did a real bad job of laminating it, but I’ll be swapping it for a volunteer pass anyway.

I must confess I screwed up the Dome Drive install early today. I’d rushed to get it done and in the classic DIY trap I had some extra parts left over. I had thought they may have been for the A&A frame install, and my setup was working RIGHT…. but it had a problem. The bracket was sagging and the extra parts were need to give it some extra rigidity. A quick email from Daren with some photos put me me straight.

Another mistake I made, I had pushed down the wheel too far onto the motor. It needs to sit up like this

However, once done I realized I had another problem. The power connectors to the motor were getting in the way of my new electronics panel. I can here you say “No problem, just flip the motor!”

Well I did try flipping the motor around, but the drive shaft is not centered, so now my wheel is further away and the spring which holds it against the dome bearing is too short.

It’s late and I’m going to sleep on it, but at least my new door closes!

Just over a week ago my wife Tammy took this photo for the R2 Builder C4 Year Book.

Now a week later the stack of parts looks like this 🙂

The Feet and Drive System arrived today from Jerry. I’m speechless yet again.
More photos here.

Tired of waiting for an aluminum frame run I decide to give it a shot myself. I doubt I’ll get it done for C4, but I’m going to give it a shot.

I have a friend who lent me his time and shop, and this is what we came up with over the weekend.

It’s the shoulder/leg mount, which allows the leg to rotate the 38 degrees from 2 legs to 3 legs.

I figured it was probably the hardest part to make out of the entire frame, so if I couldn’t get his made then there was no point in making anything else.

I think it came out pretty well, but took a lot longer than I thought it would.

Here’s a quick diagram of the frame and it’s various components –

Next up the frame rings.

Big thanks to Jon for the use of his shop and his time showing me the ropes, and to Jerry for allowing me to use his plans.
