Finally, between driving around to EVERY RADIOSHACK IN THIS COUNTY and being pissed off that Fry's cant seem to stock ****, I've finished the first of the production units, and will probably spend the majority of my night assembling the rest of them.

Sound quality is excellent, even better than my prototype, which I attribute to the use of a PCB instead of a bunch of wires on a perfboard. A few things to note. Yes, on this first unit, the I/O holes are a bit close together and they are off center. I will be drilling pilot holes on the rest of them so they dont look so stupid.

Also, due to money (and time) constraints, this first batch will be battery powered and non-permanent install only. I cant quite seem to get the same kind of clarity using a cig-lighter plug and filtered voltage regulator.(Even using 5v from a megasquirt on my bench to power the detcans still produces an unacceptable amount of noise, so I know I'm not crazy.) I feel that given the purpose of these tools, sound quality is of the utmost importance, and I'm just not willing to compromise that for the nicety of car power.

As for a permanent install, I think I have a good solution which will involve encasing the mic elements in copper tube and resin (think old-school detcans) and then bolting them to the block. This should help with any ambient noise and will do a really good job of weather proofing the microphones. I just haven't had the time between school and work to test this out yet, but if it works, it will be offered in the future.

I need to get back to work, but as promised, pics:

*batteries not included :P


Shot of the volume adjustment. Everything is thru-mounted and feels SOLID. This isn't going to break anytime soon.


The hole around the power indicator LED is slightly sloppy, I'm going to grab some more drill bits tomorrow on my way home from work so that they are neater. This is how all of the units will fit together though.(except slightly farther apart on the IO).


You asked for it, and you got it: Detachable mics. I will be offering replacement mics just in case, and also mics for permanent install in the future.


Thats all for now. Hopefully I can get the group buy thread up soon. After that, these things will come flooding out of seattle

 

Post a link to the gb thread here. Put me on the list

 

ohh yeah put me on too how much will u sell the "upgraded" mic in the future to buyers how already bought this unit??? lol

 

I assume this sensor is part of the link system then?

Is there a way i can get a part number or something to help me acquire one for a led segmented bar det can i have ideas for.

Great lookin setup you got there jeff.

 

OMG Jeff...that's so awesome it's ridiculous.

I definitely want in on the first batch, and will probably order upgrades with the second batch if they're available.

 

That looks like a standard Bosch piezo electric sensor, used on the link and a number of OEM installations. Cheapest replacement is to email Boris (google Knocksense); he sells used & tested Bosch sensors for a reasonable price.

 

The "ugraded" permanent install mic will be an included option on future releases (once its done) or will sell for something like ~5+ shipping. I haven't really given much thought to it yet. It will be cheap though . The big factor is how inexpensively I can get copper tube.

I'm trying to figure out how to do "dibs" because there is already a pretty big list of people who want these. I'll probably use that as a starting point and move on from there. As soon as I get this first batch shipped out, I'll be ordering enough parts to get one to everyone that wants one NOW, and I'll worry about upgrades later. Plus, I need to make back some of the money I've dumped into this and buy a 'scope to move much farther on the car-power thing ( my wife has been super supportive of this whole thing, but she has a limit on how much is cool for me to spend on car **** in a given month )

 

I should be pretty high up on the list for the permanent install version. So let me know when you are collecting funds. I'm ready to order.

I've been in since post #14. Get in line bitches

 

I want the removable version. Make the sensor lead long enough that I can run it from the hood through the passenger window to the driver's seat, please.

 

looks perfect, where do i sign?

 

This is the list

1. dgmorr
2.
3.
4.
....

 

please add another one...

but I dont remember the price and I'd like to know shipping cost to Italy!

 

price shipped and can get by april 10th?

 

Please add me to list of removeable type, and remove me from the permanent list.

 

I'm ready for mine (removeable install) as well.

 

Sorry for the delay guys. My soldering iron is heating up as we speak to finish the last 3 of the first batch. I turned 23 last week so there were some festivities accompanying the usual work/school/working on cars that got in the way of these being finished . Once this first batch goes out I'll be ordering all of the supplies for another batch of 20 or so.

The cross-eyed one at the top was the first of the batch...


Brain - Price is likely going to be $50 shipped. I say likely because I worked out all of my initial number crunching accounted for standard small flat-rate boxes from the USPS being the main mode of shipping. If I can make these fit (I'm pretty sure I can) then it will be $50. If not, I will adjust for the next size up (which isn't much)

Simonetrb- Pricing to Italy likely wont be cheap. When I get enough of these finished, I'll let you know.

 

How are ya Jeff? Any updates?

 

I've been somewhat overworked, so I took the weekend off (see the seattle thread). However, I did JUST (literally, 5 minutes ago) finish putting together the last of the first batch . I need to test and package them all as sets tomorrow night when I get home, and the GB thread will follow shortly after.

For those that are interested, these first batch will be followed shortly by another batch of 20 to cover all those that were interested. If there is demand beyond that, I'll see what I can get worked out with the mods as far as an ongoing thread (ala olderguy 02 clamps/ Brain MSs).

Still In.
I believe I am 7th on the list. Ready to send payment, shipping to 08332.

Thanks

 

let me know the final price and PM me and I'll pay. I'm going to the dyno on April 10th.
