Now you can use any kind of head you want for whatever feel is best for you. It's amazing how simple and elegant this design is. Can't wait to hear from Jerry on this. Great job!
    Thanks Dan you da man.... honestly the triggering of the EPro drop in sets the bar pretty low at least from the demoing I experienced .... ChromeBoy's idea for this design raises that bar substantially .... rather impressive IMO... Credit goes to him .... well and his wife of course for having the right cake pan ..... and not hitting ChromeBoy over the head with a Rolling pin when he stole it from her kitchen

    Yeah, we already conciderred the bearing edge ... there is no real need to have the pan sit directly on the bearing edge of the drum since all the triggering is self contained in the pan design and you don't need the simpathetic shell vibrations for the rim triggering .... there is plenty of room with standard lug screws to put padding under the lip of the pan, I will prolly try some simple 1/4" weather stripping under the lip ... or even a couple layers of electrical tape. I actually think though that the pan will not be as damaging to acoustic bearing edge as a mesh head would be ... the pan is not abrasive, actually pretty smooth and the pressure is even around the entire circumferance ... so just a tiny bit of additional padding/protection would be wise.

    On the 3 bolt platform connection ... easily could be used. If you notice the rubber washers on my platform ... actually faucet washers.... I put those in for 2 reasons .... one they are wider than the washers I normally use and give more stability to the standoff, 2 they give that tiny bit of isolation... not too much to the platform piezo. So yeah, I think the 2 bolts is sufficient, but as you say 3 would be even more stable and a good idea Chris..... see, you are not completely burnt out ... you're still cookin Chris

    Yeah, 14" and 16" dual zone conversions will be the more informative testing ... Another aside .... one thing on my own crossbar trigger design I have always concentrated on is positional detection with head and rim where applicable.... The PS is also working with this drop in design. I do not see any insurmountable obstacles with the larger diameter drums, even if additional mods result I am sure it will be possible with favorable results.. when I get the set of pans, I will go to the 14 snare and 16 floor tom next.

    And I know you have already worked on the 14" CB ...

    One thing that ChromeBoy related to me was that slight modification of the pan may be necessary on some snare drums ... if the pan bumps the interior lug hardware you might need to grind out or drill out so everything fits nicely.

    I hear ya Jman. I'd almost never have the need to switch from E's back to A's. The only times I'd want to be able to do it is in the event of a module failure at a gig, or to appease a f.o.h. engineer who isn't wild about mixing e-drums.. although I've gotten a lot less crap from those guys since I picked up the TDW-20.
    This way I just keep a set of mylar heads, drum mics and some cymbals in the trailer and I can quickly switch from E to A if I need to. The drums I'm using are cheap poplar shells, but with decent heads and a few minutes of tuning, they'd get me thru a gig.

    FYI...
    This is where I got my pans. They have a 17" too, which I didn't see on the other site, in case anyone wants to try an 18" floor tom. Not sure how it would work. I've done 3 x 14" and they are great. I think Jman has a 16" floor tom on his kit that triggers very nicely, but it uses his crossbar design.

    They'd add some cost but might "pretty up" the build a bit.
    Yup, I remember in our emails you had already investigated the idea of using the smaller jack that would just slip into the existing vent grommet. This is something that was also very appealing. Like you say the cost of the build goes up a bit .... also, you would want an 1/8" to 1/4" TRS adapter to connect to the TRS cable or TRS input jack of the module ... the reason I went with parts I already had in my shop.. And the usual jack we normally use that stays in the drum is fine too ...

    One thing I noticed about the Pearl EPro is that the jack remained in the shell. I thought I would build something that eliminates that for those that really want to quick change back to acoustics and have the acoustic drum exactly like it is normally without jack... But honestly .... I am not that excited about changing back and forth from acoustic to electronic to acoustic ...... jeez, I haven't been playing acoustics for some years, but one thing I remember quite well... once I have a drum tuned just like I want, the last thing I want to do is pull the head off again

    Thanks Chris. Its been a fun project. The web store that Jman linked to has better prices on pans than I found. They have a package deal for $32 that would set a person up with pans for a 6", 8", 10", 12" and 2x14" drums.

    Jman's redesign really improved the performance (especially rims) of this thing. He thought the "donut" of foam may have isolated the rim piezo too much causing some of the inconsistencies.

    I had also considered a wire "pigtail" thru the vent hole, but since my shells already had the jacks installed, I just used those. If someone wanted to spend another couple of bucks, you could swap the bullet-style quick connectors for a 2.5 mm jack and plug. I think it would fit thru the vent hole on most drums.

    By the way.... I did find cake pans at a good price ... I went ahead and ordered enough to convert an entire 9 piece kit ... I plan to do more experimenting so wanted all sizes I would normally convert.... price of all those pans was only about $70 including shipping here:
    http://www.cooksdream.com/store/cate...t-daddios.html

    Edit, the prices have gone up since way back then. There is also another brand of round 2" deep pans on the site. I have never tried those but here is that link: http://www.cooksdream.com/store/category/bab.html

    Chromeboy's dual zone drop in pan with Jman mods.

    So, when Chromeboy emailed me about his ideas for the drop in conversion I remembered doing quite a bit of research into the cake pan conversion a few years back. There was some posting on the DIY site if I remember right. Hellfire has done conversions using a pan as the base for a complete edrum pad. But outside of those that have used the Roland parts for doing basket conversions the concept for doing a completely sustained drop in unit that quickly drops in or is removed from an acoustic drum was never really perfected that I know of. At least a conversion where all sizes of baskets/pans are already premade in a perfect size that will fit almost any acoustic shell..... universal and very economical for the clean results you see.

    Funny the timing of things, during the course of my conversations with Chromeboy .... Winter NAMM happened. After seeing and playing the Pearl EPro this little project took on a little more meaning for me... And I will say that the poor rim triggering of that Pearl kit was part of the inspiration to fine tune this DIY drop in. I don't like to make idle boasts, but I will say that this little project by a couple of Ham fisted home DIYers triggers circles around the EPro drop ins.

    OK, so when I received the original drop in prototype from CB ... I started by removing the small factory wires from the piezos and replacing them with my own beefier wiring. Another goal I had was to make this drop in so that no modification whatsoever is needed to the drum shell.... simply drop it into the shell and plug n play. In order to attain this, instead of putting a permanent jack in the air vent like I normally do, I decided to make a jack that the connectors will slide into the vent hole without even needing to remove the vent grommet . In my case I used a Pacific shell that has the threaded air vent grommet, which is a pretty good test since the interior diameter of that grommet means the jack connectors need to be pretty small. I used quick connectors small enough to fit. 1/4" are too large, so the smaller ones, or bullet connectors, or pin connectors are the way to go. After replacing the piezo wires and installing my jack system, I tested the drop in.... without going into all the details..... Murphy's Law kicked in .... a short time later I found out the head piezo had bad continuity and after tearing apart, resoldering, replacing, retesting, pulling apart, and so on and so on... hours later.......... you know how you just don't want to believe a piezo that has no apparant damage to the human eye could be a proble ..... well, I finally replaced that and did a few other mods.... See below!
    Alright, so Murphy's Law is not always a bad thing when the final results it causes are good. Since I had to rebuild the triggering from scratch I decided to implement another change to the design... an adjustable platform for the head piezo. I realized this would be a good thing when considering the different heights and types of trigger foam that people tend to use in these conversions. I generally use trigger foam 1 3/8" tall, Chromeboy's was 1 1/2" tall .... so you can see that the spacers needed to attain the proper height above the lip of the pan would vary depending on trigger foam, double sided tape used to stick piezo, etc. So, I decided on the adjustable height platform.... I simply used a set of machine screws with nuts, rubber spacer, washers etc.. drilling the platform and pan. Now the platform can be raised or lowered by simply adjusting the height with the nuts, tighten it up, test it ... once the proper height is attained a drop of blue threadlock will reassure you that nothing will change, but blue threadlock is the semi-permanent type that you can loosen if you ever desire in the future.

    Before using the adjustable platform I was getting some problemed triggering, where an occasional rim shot would trigger off the head, and module parameters did not completely solve the problem ... adjusting radically would make the rim triggering less sensitive, and when the rim triggering was adjusted sensitive enough .... errant rim shot on head .... long story short, since Murphy's Law had totally hosed my original testing and I never really determined how much of the problems were piezo related, foam related or platform related ....... end results: the new piezo with new trigger foam and adjustable platform corrected this completely ... Now as Chromeboy posted above with a preset trigger type the triggering is plug n play with just a very minor bit of adjusting necessary to fine tune. I've embedded a couple pics and here is a zip folder with some more.... fun, fun, fun, ...... I attached a couple pics of 2 different types of install the first is with the jack installed directly in the pan for open bottom drums. The second is with the deep panel jack installed in the shell with quick connects.

    Collaborating on this project as Chromeboy also said has been a blast.... two heads better than one..... It is great to see, what a couple everyday guys can do, bouncing ideas off one another ...... And in the end "Baking" up a project like this .... try it, it's a piece of cake (Pun intended) J

    Here is the zip: https://files.secureserver.net/0swMwPu2l175nS This is a new link with just a variety of Drop in Pan conversion pics. Since this thread was begun I lost all my on line pics so excuse the potpourri of pics. Most of my pics in further posts of this thread will be missing, so this is what we have, not everything but at least a start .... , J

    I can't wait to get back and post on this ... it has been one of the most interesting and fun DIY projects I have worked on to date... Chromeboy emailed me with his great idea and we went back and forth after that, he mailed me his first prototype project.... Very cool bouncing back and forth via email with Chromeboy, brainstorming and rethinking this very simple yet very functional trigger design.... gotta get back and finish up email business in the real world and then I'll be back to add a little to our progression on this one... J

    PS..... now you can see what I was doing when I posted that recent thread on Bad weather and good DIY ....
