S4 Encoder Group Buy
 

Hello Community!

2175 is doing another US Digital S4 Encoder order (the same ones that were featured in this thread). We are getting the S4-120-250-N-S-B model and the more we order, the lower the price will be. My team used these encoders last year and have had amazing results with them (meaning we actually got them to work) so I would highly recommend them.

If your team wants to get in on the order, either comment in this thread or PM me. We are going to try to place the order either Friday of this week or next Monday.

We are also going to be ordering the CA-MIC4-W4-NC-3 3ft cables that go with the encoders, so if you want some please include the number you want in the post/PM.

Re: S4 Encoder Group Buy
 

Is anyone else in?

Re: S4 Encoder Group Buy
 

What are costs and quantity needed to get that price?

Re: S4 Encoder Group Buy
 

When placing your order, let US Digital know you are a FIRST team. Their policy has been to give FIRST teams the "next level discount" price break.

Also, when you place the order, please thank them for their sponsorship of FIRST by providing FIRST teams with no-hassle discounted pricing!

Re: S4 Encoder Group Buy
 

Please let us know the cost and what quantity we will get a price break.

Re: S4 Encoder Group Buy
 

We would also like to know.

Re: S4 Encoder Group Buy
 

We would like to know this as well. ;)

Re: S4 Encoder Group Buy
 

I am waiting for a response from US Digital, if they don't get back to me tomorrow, I'll give them a call.

Re: S4 Encoder Group Buy
 

We are interested, once particulars are known

Re: S4 Encoder Group Buy
 

We may also be interested once we have more details.

Re: S4 Encoder Group Buy
 

Same as everyone above, interested once details are known

Re: S4 Encoder Group Buy
 

I am interested as well.

Re: S4 Encoder Group Buy
 

We had been very interested in this encoder as well. When we received a waiver from USDigital to purchase 10 of them we were still a bit shocked at the price. Don't get me wrong. these are really nice encoders for many reason.

Ultimately we ended up ordering these encoders. They run at basically the same price, if not a bit less when bought in 10+ quantities, as these USDigital encoders from AndyMark.
Our kids destroy the EP4s because of poor handling and awareness of how delicate and fragile they are. So, hopefully, these sealed units will last a bit longer.

Re: S4 Encoder Group Buy
 

Please, please, please post your experience with those sparkfun encoders as soon as you feel you can provide good feedback!

Thanks!

Re: S4 Encoder Group Buy
 

I got a quote from US Digital today and here is what the price breakdown is for both encoders and cables:
Already, we have these orders:
2175 - 6 encoders, 12 cables
3130 - 6 encoders, 12 cables
3883 - 6 encoders, 6 cables
4607 - 6 encoders, 6 cables

We are looking at placing the order either Monday or Tuesday so if you want some encoders/cables, please let me know before then.

Re: S4 Encoder Group Buy
 

Put 4536 down for 1 encoder and 1 cable. We'll play around with it, and if they are as magical as you make them seem, we might take a few more in the next group order. :p

Re: S4 Encoder Group Buy
 

I set up a quick vi to run and sample the output of the encoders we ended up purchasing from Sparkfun.

Adam specifically wanted to know ho well they operated in the 2000 RPM range as well as if they became warm due to the very minor resistance to rotation they have.

These encoders are rated up to 5000 RPM. We tested them at just over 2500 RPM. They ran continuously for over 20 minutes during the tests and never got warmer than room temperature.

Below is a graph of the A and B channels. The slight fluctuation is attributed to the mechanical set up used to drive the encoder. As you can see, it was a bit janky, but it worked.

Re: S4 Encoder Group Buy
 

Please put 3502 down for 4 encoders and 4 cables.
Thanks!

Re: S4 Encoder Group Buy
 

Please allocate 6 for Team 2135--no cables needed.

Thanks

Re: S4 Encoder Group Buy
 

3081 - 4 encoders, 4 cables.

Re: S4 Encoder Group Buy
 

We'd be interested if it's 360 count. Why the lower count?

Re: S4 Encoder Group Buy
 

Put us down for 4 encoders & 6 cables

Re: S4 Encoder Group Buy
 

They want to be consistent between what they are ordering. They also plan on running them at higher speeds so the 120 is better for that application.

Re: S4 Encoder Group Buy
 

Put 2202 down for 2 encoders and 2 cables.

Thanks.
I will need an invoice (email should be ok), and we can mail you a check.

PS: If you get another order or two, you should be at 50+ level, and can get the 100+ pricing. What would that be?

Re: S4 Encoder Group Buy
 

^^Accurate

Here is what we have for orders:
2175 - 6 encoders, 12 cables
3130 - 6 encoders, 12 cables

4334 - 4 encoders, 6 cables
2202 - 2 encoders, 2 cables

Total Encoders: 49
Total Cables: 63

Re: S4 Encoder Group Buy
 

if you are that close to 50, we can take one more of each.

Re: S4 Encoder Group Buy
 

With that order we now are up to 50 encoders, so we qualify for the next price break!

Re: S4 Encoder Group Buy
 

If it's not too late, you can put 1736 down for 2 encoders and 2 cables.

Re: S4 Encoder Group Buy
 

How fast are you running them that you are having issues? We've run them pretty fast w/o issue.

It's a bummer because you're giving up resolution for free.

Re: S4 Encoder Group Buy
 

Out of curiosity, how fast have you run the 360 click encoder before?

Re: S4 Encoder Group Buy
 

If you're still adding orders, please add 1912 - 2 encoders, 2 cables. Thanks!

Re: S4 Encoder Group Buy
 

Don't forget, the FPGA sampling rate has been increased this year to 1MHz (was 153KHz in cRIO).

Re: S4 Encoder Group Buy
 

360 1:1 off cim.

Re: S4 Encoder Group Buy
 

So I will be placing the order today and here are the teams that we are getting encoders/cables for:

Total Encoders: 54
Total Cables: 68

The final price per encoder is: $53.97
The final price per cable is: $6.67

I will be sending out invoices to those who responded to the thread/sent me a PM later today.

Re: S4 Encoder Group Buy
 

Don't forget to include something for shipping to the team. Priority Mail Flat Rate Small box is $5.95, or something like $5.25 if you pay on-line.

Re: S4 Encoder Group Buy
 

We will most likely be doing $10 for shipping/handling (same as the last time a group order was placed).

Re: S4 Encoder Group Buy
 

We are placing the order today, once we know how much the total order is, we will be sending out invoices to everyone who ordered encoders.

Re: S4 Encoder Group Buy
 

Thanks again for doing this sir!

Re: S4 Encoder Group Buy
 

Mail you a check, or do you have a paypal account? Bitcoin?

Re: S4 Encoder Group Buy
 

Were the invoices sent out? I haven't seen anything and wanted to make sure my spam filter didn't eat it.

Thanks

Re: S4 Encoder Group Buy
 

Check would be preferred, and invoices are being sent out now.

Re: S4 Encoder Group Buy
 

All of the invoices were just sent out, if you did not get one, or if you notice an error, please contact me directly.

We will ship the encoders/cables to you once we have received your check.

Thank you for your orders!
