Noticed quite a couple of threads asking about how to muffle for HDB etc, here's ONE option:

A thread from the PDF.

http://www.pearldrummersforum.com/showthread.php?t=80045

Okay, this thread will show you, how to build an e-set comparable to the high end ones like Roland/Pintech/Hart. I CAN NOT STRESS ENOUGH THAT THIS PROCESS IS EXTREMELY SIMPLE, ANYONE CAN DO IT. I HAVE NO ELECTRONIC KNOWLEDGE PRIOR TO ATTEMPTING THIS OTHER THAN READING SCRAPS OF INFORMATION ON THE INTERNET.

Parts List:

1. An Existing Drum Kit (Or you can buy a really cheap used one, and re-wrap it for the purpose)
2. A Drum module. I purchased an Alesis D4 from a pawn shop for 112 dollars. You can find a module on ebay, or buy a new one, like a Roland or Alesis DM5.
3. A set of Remo Muff'ls to fit your drums. You don't need one for the kick, you only need an EMAD head, or some mildly dense foam.
4. Practice cymbals. Anything plastic. I got pintech ones from musicains friend .
5. Steel sheeting. I used 30 guage, but you could use 26 or 28 or anything really I think. The exact item I used was - Home Depot Master Flow 24" X 36" Galvanized Steel Flat Sheet ($5.89)
6. 1/4" instrument cables, they can be really cheap quality, as its just for sending a signal. I got the $5 20 foot ones from musicians friend.
7. Parts from RadioShack. I listed the part #s and everything, and you just go in and they have drawers and everthing is clearly labled. Or you could just print this off and hand it to the guy.
(x4) Piezo Transducer Catalog # 273-059 - $3.29
(x5) Inline Jack (Pack of 2) Catalog #: 274-340 - $3.99
(x5) Piezo Element 1500-3000Hz Catalog #: 273-073 - $1.99

So thats 4 of one type of Piezo, a total of 10 Inline jacks, and 5 of the other type of piezo. The parts from radioshack and steel will be about 52 dollars with tax. I spent under 250 dollars for this whole project.

Many more ideas here

That PDF thread and the edrum for free site were what got me started on building an e-kit last year. That, and I later signed up at http://www.electronicdrums.com - which is an excellent resource (and more importantly, an active community of edrum hobbyists).

Point to note, though, I bought the Remo Muffl's and used Mathias' method..but it gave me lousy results, uneven triggering etc. In the end I made triggers out of black acrylic cut to size, attached Roland cones and self made piezo triggers to them, and used L-shaped metal plates to attach them to Pearl RT shells. Worked well for awhile with the Roland TD-6V, then I decided I still preferred acoustic drums better and sold the lot (including the RT and TD-6V) for a loss. :(

A hard lesson, but nonetheless fun to execute.

I have the acrylic trigger bridges and even a custom-made hi-hat variable resistance controller lying around somewhere still. Wonder if anyone has any use for them, haha.
 
well that website's needs to pay per view.. really sucks but luckily i found the better bet from the lot...

Beatnik's website, initial idea and the man who should be inducted to the hall of fame of DIY since he started out the main idea and such, and other people used it to make money outta it, which really made him really mad...

anyways, the website weckl-x gave is still nonetheless great but if any of you guys wanna try out those superb roland td-20 or 12 which has COSM sound samples which u can do practically anything to it, than you guys might wanna try www.vdrums.com

I've started my DIY project by finding out the parts needed and such.. But after some futile searching, still no luck on good Places to find them parts...

here's the link, http://derksens.com/Beatnik_mirror.htm

a much organised site, and also geared towards roland modules.

anyways elevenine, where'd u get ur piezo's from?? any idea where you can get VRS switch for edge triggering of hi hats and choke capability? VRS stands for Virtual Rim Switch.

i've found them piezos from digikey but digikey's from canada so shipping should be implemented when i order from them.. I've tried sim lim tower but to no avail too.

And stereo jacks (female) and stereo cables... are real tough to find in a cheaper form... well if u have places, let us in yeah.
 
Like I said, electronicdrums.com is mainly for the community aspect..FYI, I bought this guy's variable hihat controller from there..an ingenious design that allowed full control of the hihat's open to close.

edit: also, I made myself a working version of beatnik's variable hihat controller out of parts from Sim Lim tower..so really, you can find practically all you need from there. But I ended up using the other guy's design because it was so much sleeker and more sensitive.

Piezos can be bought from Sim Lim tower..if you can't find them, it means you haven't been looking hard enough. Try all the shops across all levels. I rarely bought stuff at the same shop more than twice. It's been awhile since I sourced for parts now..but trust me, you can get a buttload of the smaller piezos (for snare/tom triggering) for Very cheap. For bassdrum triggering, look for a larger piezo in other shops, they should be sold singly. Outward appearance doesn't matter, as long as it works and the metal/ceramic contact isn't broken.

As for jacks and cables..again, Sim Lim tower. Just ask around all the shops you can find..when I was building my ekit I was there practically every weekend.

edit: And finally, for whatever hardware you can't find in Singapore, try www.mcmaster.com for your hardware needs. I bought memory foam, rubber tubing (to wrap around the rims of the drums so as not to produce unwanted rimshots), and aluminium strips from them. Shipping is quick and reliable so I thought I'd recommend them.

The VRS switch is not worth getting, IMO. You can't find it here and it's quite expensive to order it from the States. One more reason to go back to playing acoustic drums! (:

And yes, I agree that anyone who wants to DIY edrums Has to view beatnik's designs..they work very well.

edit: Sigh, it's been so long since I've broached this subject..maybe I just wanted to put it at the back of my mind. A lot of wasted money was put into it, including the custom designing of acrylic trigger bridges instead of aluminium bars, and buying the damn expensive Roland cones from Sweelee at $12 apiece (if I'm not mistaken). *sniffs* in the end, it's not that the edrums didn't work well..but I felt that they were so limited compared to regular acoustic kits that I decided to sell everything and get a new acoustic kit for myself.
 
No doubt man the acoustics are way better than the electronics but we are living in singapore here, and many in HDB, like me. So having acoustics in my room, im in a predicament, being that im disturbing the people down below and on top when im playing, including my fellow family members in the house.

If you have a bigger budget lets say around 4000, and i know, i've played the TD-6KV b4 and the sound is simply "not that good" comparing to their high end modules like the flagship td-20 or td-12 with the COSM sound samples which you can practically tune ur drums to any material, depth and like any other acoustics you have!!

Like acoustics, you have low end pearl RT and high end Ayotte customs. The same applies to electronics drum, they have low end td-3 and high ends td-20 with even positional sensing!!

I've placed my budget around 4000 for my conversion, taking into consideration of the piezos, cones, crossbar, l brackets and the td-20. I already have the drums, just needing 3 more toms and im practically done.

With ONE TD-20, i can have an 8 piece set, 2 snare, 3 rack, 2 floor, one Bass, all dual zone triggered.

Cymbals: 2 crash, 2 splash, 1 ride, 1 china, 1 hi hat, 1 aux hi hat.

the splash and aux hats and china are single zone splits from an aux input.
the rest are dual zone.

So all that said and done, as many other avid DIY'er would say, hunting for the materials is the best part of DIYing. Well, probably that day, most of the shops there are closed, i went there around 5 plus so yeah..

And they don't have piezos of 35mm. Largest i saw was 27mm, which is simply not sensitive enough for roland modules, so im sticking my wits to DIGIKEY.

Some of the stuff i need i have to get it from overseas like the TD20, VRS switch, and such. Well yea the VRS switch is quite expensive, but its worth the money and more sensitive than buying a SMARTRIGGER CYMBAL which uses other kind of switch to choke the cymbal.

So an added advantage that you have with the td-20 is that u can play practically anytime u want, you can tune ur drums to sound anything that you like, it costs MUCH MUCH cheaper to DIY but if something goes wrong, than it's better you buy ready made triggers from this guy called JMAN, a cheaper alternative than buying a triggered pad.

Elevenine, have you seen other Piezos about 35 mm in diameter for the brass parT? Mostly, i saw most of them which are salvaged from other buzzers or those stored in like parts area where they don't know the khz of the piezo and such, so i guess getting my piezos from digikey's the best.

cheers:D
 
ermmm...i do have 4 roland cone here for sale..35mm type..did my DIY project abt 9 months ago...all DIY result are good..i stop at buying e-cymbals and module part...either u get a really good module or actually if getting a decent one u will get sick awhile later...dunno others but to me i will...coz u cant get the sound u like...then now im back to acoustic set despite im living in HDB as well...i used a rhythm traveller to convert and all tom are made to dual zone with rim hitting,rim shot capable. if u guys happen to need to buy the roland cone i can sell them to u as i dun need them now...i do help ppl converting too...but not free of coz...result is good...tested...do PM me if u wanna buy the roland cone or wan me to help converting it...thanks!! hope this post is some how linked here... :D

Cheers!! good luck to ppl doing DIY ^ ^
 
Man, if I had $4k to blow, I'd buy me a pretty Mapex or Sonor kit haha.

Oh yeah, are you sure the Smartrigger cymbals uses some other system for choke capability? I would've thought that it's the same technology.

As for larger piezos, I do believe I used a couple of 35mm ones to trigger the bass drum and floor tom. You're right, some of the piezos look like they were "salvaged" from other components, but as long as all the contacts are good, I think they should be fine. Hey, the most they'd cost is only a few bucks..and time spent on resoldering should it happen to fail..heh.

If you have money to spend, then what the hey, might as well order everything so that it all lands on your doorstep haha.

Have you thought about what kind of controller you're gonna use for your hihats? Getting the right device takes some playing around, and is definitely important if you're using a TD20 which supports full open to close hihats.

Since you're DIY-ing, you probably won't be able to take advantage of the extra TD20 feature that allows you to squeeze the hats together really tight for an extra tightly-closed sound. It just occurred to me, I remember seeing that feature in the demo video.

I've played a fully tricked-out TD20 on Roland pads at someone's place before..and though I was impressed, I felt like I just played some video game. Still, I remember playing with my e-kit last year and at least it appeared to be making much noise, as compared to my current kit with Soundoff mutes. Lol.
 
DIY E Drums

You do not need a larger piezo piece for your 'bass' drum. There is no advantage.
Actually, there will be a disadvantage as the pickup area is larger, and the false triggering vulnerability is higher. The piezo the size of a 20cent SG coin is all you need.

There is an argument for using a larger piezo for a 'snare' drum, despite the vulnerability, as you may wish to pick up nuances such as rolls, which you are not likely to do on a bass drum.

One kit I built, actually uses a 5" mesh on a rim for the BD. The other uses a 16" mesh on a half shell, and I have used the same trigger I made for a conventional kit using a 22" BD.

A trigger can be purchased off Maplin for 20p. Maplin is in the UK, where I live. Dick Smiths or Jaycar in OZ, should have them as well. You can buy these online. Mouser, Parts express etc in the USA will have them as well. But you can get them in SG from Simlim though I cannot tell you where. But you could canniablise piezos from old telephones or sounders, you want the flat disc ones. Try some karang Guni activity.

Re: Hi Hats, pearl makes some plastic practice cymbals but these will flex in a sock cymbal set up ... they are cheap and you can use these instead with a trigger for cymbals that will sway. I use these as cheap crashes. For rides, I bought some old visulite, before they were bought up ny Hart or Pintech (I forget who bought them)

A continously variable HiHat is actually easier to make. But I don't use one as my module is a DM5 which doesn't do that... and I don't need it. If I really need all that variation, I just mike up some real hats.

I am in SG for a couple of weeks , so if you want to raise queries I'd be gladto help.

They have yelloww sensor strips which needs much more grip to choke than vrs switch.. which means they are not so sensitive, as far as their triggering parameters go, they are still better than diy.

U sure about that mate?? A simple good ol potentiometer can do the trick mate, it even goes to the extra tight sound! Not needing any adapters and all that!

But im going the safe way and try an FD-7 controller. Those can go the extra mile of extra tight capabilities.

here's proof!
