Vintage Simmons Drums (UK) Users Group

I've finalized the design stage and have so far ordered about 70% of the parts required. I've ordered enough to do around 40 of them at this stage so if anyone finds they want another, I'll have some on hand.

I need to delay getting final circuit board manufacture done as I need to confirm that the battery holder I have ordered is going to fit on the board right. (The picture of the ordered item didn't match the datasheet info, I've gone by the datasheet but don't want any nasty surprises when board turn up with battery holders that wont fit.)

Negotiating with suppliers to get some of the high cost items at the price I have budgeted is painful, but so far the estimated price of 80 bucks is looking spot on. The ram chips have been tough to source. The originals used by simmons draw around 100uA in standby. This would be no good for use with a 3.0v button cell...it would go flat to quickly.

I have found a source of 6116alp-10 rams which are great, they only draw 0.05uA of current ( a 2000% decrease!) in standby which will mean the lithium battery will last a number of years before you would need to replace it. On that note, I will write a little "blurb" sheet for each cart. Essentially to change the battery, undo the case screws and take the lid off. After wondering at just how lovely the workmanship inside is (..joking) plug it into the SDS 6/7 turn on the SDS. This powers up the cart and retains the memory whilst you remove the battery and slip a new one in. Reverse the previous actions, remove the cart and screw the lid back on..simple

I was going to try and fit a little circuit with LED to warn of low battery, but sadly no room to fit it..=(

Mate,

Can't wait to get me two carts from yis. Go Richard!

PCB's have arrived from manufacture. Still waiting on a few bits n' pieces but will put together one board to test all is ok...the smoke test..lol. Again don't flame me for my photo taking prowess. Taken with a pedal powered mobile phone using candles for lighting.

As soon as I am happy that all is set to go, I'll let those of you who have contacted me know about my paypal details and I'll put them together and mail them out. As you can see if you want more, just let me know, I have had 50 pcb's made during this run.

Well, I'll start by simply saying I have committed the cardinal sin when dealing with the technical side of Simmons gear....DON'T ASSUME ANYTHING IS AS IT IS DRAWN. Once again, the schematics simply don't match what is layed out on the original PCB. I'm kicking myself at the moment, need to alter a few things and work out if I can change the boards I have (ie cut a track or 2 and add some connections....those who have ever looked inside Simmons gear will know what I mean..lol)or get some more run.

Dave Simmons (if he ever visits and reads this stuff) I have come to the conclusion either;

1) Someone inside your old business was out to ruin you...or

2) You were paying for some engineering staff who were verging on incompetent!!

I have worked on enough of this gear to know just how bad some of the designs are. Don't get me wrong, the concepts and sound are second to none but the implementation of the hardware is truly bad in some cases. The SDS7 is probably the worst example. They are SO temperamental I can't believe they were built the way they were with the intention they would be carted around and gigged. You just have to look at them the wrong way and they stop working. The sockets for the cards are simply atrocious. God help anyone who has lost the little plastic card key in any slots...the board can misalign when plugged in or moved (vibration) and it WILL kill the board. The case design is not very rigid, all the cards use this non rigid case for support. Mis-handle the unit and you apply stress to all the PCB's leading to track/connection fractures. Simply wrong!!

Well now I've got that off my chest I'll go back to burying my boot up my own arse.

Be patient, I'll have a look at what I can do then get back to you.

A schoolboy error :-(

I think there are many reasons for errors on schematics:-

1) As a company they were very experimental, and didn't always follow best practice updating documents (how many of them that you've seen have hand-drawn/unreadable changes on them?)

2) Some of the schematics that are out there have come from various sources, and there's nothing to say that they're the most up to date ones, or ones that match the hardware we have. Even the SDS3 schematics are full of errors, and that's a very simple circuit !

3) As you say, most bits of Simmons kit have wire / component mods (for example I've an internal service note that says the latest pcb design for the SDE has a chip laid out backwards, that meant they had to make a piggy-back board to make it work !). These guys weren't using foolproof CAD tools to design the stuff !

It makes it a little more of a "challenge" to get stuff working again. I don't think there was anyone genuinely incompetent or out to ruin his business. It's just one of the problems you get when you leave Engineers in charge of products (and that's not meant to be rude about Engineers, after all, I'm one...)

Good luck with the memory cart, at least it will look like a genuine Simmons product with all its mods :-)

Whilst we're on the subject of the memory cart, I happen to have picked up an original over the past few weeks. I need to change the batteries, can anyone recommend a suitable replacement?

Thanks

[Non-text portions of this message have been removed]

Just venting..lol

I'm also an electronics engineer and I understand the situation regarding schematics in the public domain. But I stand by my statement about the SDS7..it's physical design is terrible. I simply moved mine from the rack it is in to the workbench...bang it stopped working. Took the top off, reseated the CPU and memory card and it's all ok again. That's my point. Even though I acknowledge the units age etc it is simply too fragile to be used in a gigging format. (even from new..this has been confirmed to me by people who did try to cart them around way back then)

I recently had an email with a well known chap here in Oz (makes a highly regarded series of mods for the TB303) and he said he was servicing the SDS7's when they were new and they had the same reliability issues back then. He agree's the hardware design is poor.

Given that it was a big ticket item back then and given the ability to use hindsight, better PCB to backplane connectors really wouldn't have added too much to the cost. I have fixed a number of SDS7's and they all had the same problems. As an engineer, this indicates to me a flaw in the design. I guess had Simmons survived, these design changes would have filtered through due to gradual improvements in design and production processes. (as did changes to pad design etc ) Again, I'm not bashing the product, simply stating a reality regarding the SDS7.

Anyway, found my issue, need to cut one track and add a short wire. Not happy doing this sort of thing but it's either do that or get a new run of 50 boards done. The way PCB manufacturers price boards, it's not economical on a small run of boards like this to do proto's and samples. Yes if you order a few hundred and up they will generally supply production samples to test.

Somehow during the PCB layout, I managed to cross link a track. Have modified the proto unit's PCB and it's working a treat.

Any AA size "old school" nicad will do. You'll need 3 and a soldering iron to do it. The reason for old generation nicad is that the cart has no fancy charging circuit (as most new types need to charge properly) just an 18ohm resistor to restrict current and a diode. When fitting the new ones make sure you check the polarity as you connect them. Take note that Simmons recommended you plug the cart in once a month for a few hours to recharge the battery.

spent this afternoon (as it's raining cats and dogs) putting together the first 5 boards (foto's in the photo folder). I guess I can do about 6 or seven a day so I should have all the boards put together by this time next week. I'll then test them all, put them in the cases and box them up for mailing.

I'll contact all on my request list and let you know my paypal details. I'll check out the postage cost, but I think it will be the same for all (unless you are in some exotic location) and covered by flat rate international postage.

I'll contact you all for postage addresses soon.

bit of bad news today. an order for ram chips to complete current requirements has been delayed due to flooding in local area of supply.
could be delayed by ten or so days...=(

I'll send out in order of date attached to original requests for carts.
Hope this doesn't upset anyone.

Cheers

Not upset at all, and I think it's safe to assume that the other SDS7 owners waiting on the Cart aren't either.
I'm just tickled pink that you are actually making these things!!

Thanks for doing this !!

  Hi Richard ! My name is Alfonso I sent an e - mail last week , but I guess you have not received it. I just wonder if it´s possible you send me one of your memory cards clones.

I'll send out in order of date attached to original requests for carts.
Hope this doesn't upset anyone.

 Hi Alfonso, I got your mail but when I tried to reply to your email address the mail kept bouncing back to me saying it was undeliverable. Sort of gave up and was hoping you'd request this way. Yes you have been added to the list of requests. All boards have been completed, just waiting on a few bits that have been delayed due to flooding in the country of supply. The cart works out at $80.00 US + $20.00 US to Europe from Australia. On the postage, I was left scratching my head that it was cheaper to send to the US and UK (which is a further distance than Europe) yet the European cost was higher. I can only put it down to what the OS postal service charges Australia Post to handle incoming mail. Anyway if all goes to plan, I will be contacting all people who ordered late this week early next regarding my paypal and required mailing addresses. I have enough boards and parts to do 15 more if anyone else wants any otherwise I'll probably put them together a few at a time and offload them via Ebay or similar.

Hey Richard...
Quick question, did you get my order for the 3 Carts I wish to purchase?

Cheers

Yep, your on the list Alan. =)
