Winstar E-Paper Query

Hi all,

I hope soon to be getting in one of those Winstar 10x2 E-Paper displays. At the moment I'm trying to decipher the supplied datasheet. :( Has anyone had any success interpreting the datasheet or has some example code? :?:

Cheers,

Nick26

Thanks for the referal. I did have a look, but I'm looking to go even smaller. :wink: Any suggestions for decent links to flyback converter or similar boost converter calcs would be most welcome. I'm sure I could get the PIC to run the PWM/PPM as well.

I've been looking to make a similar detector and had a look at all the hits google gave, but am looking to see how small and low power I can make it. Most of the circuits I've found use the large audio transformers/inductors. Does anyone have suggestions for shrinking the magnetics or the calcs used...

Hello again, After a small hiatus I decided to test my sensor code, by borrowing someones vacuum vessel. to my dismay, once the pressure was taken down a bit, my sensor readings were way off a relative pressure meter that was connected to the same chamber. On one particular low pressure day, the sen...

Wind on life a few weeks. Thanks for the link, some good info. I've scored some cheap remotes from ebay. You can stick a few K ohms across the pads (once you've ripped a part) and the 'buttons' still work. I'll have to try and identify the ICs on it another day. Now where did I leave that bit of pap...

Ipod Touch Gen 2 Remotes

Hi all, Now I've just received my shiny Ipod Touch, I'm thinking of building some remote control schemes for it. Emulating the stock inline button remote, so I can use my own headphones will be easy enough, but... I'm thinking of using the spare steering wheel controls on my car for changing tracks,...

From scouring the usual places like hackaday, stepper motors seem a good way to generate small amounts of power. One project I saw, was generating power by using a stepper motor between the legs. He had the insides of a tape measure (spring) attached to the motor, with a cord from the spring mechani...

4x40 Character LCD backpack

Diggin through my junk box, revealed a huge 4x40 character LCD display I picked up at a radio rally ages ago (Data Vision P73-1). Been searching online, only found a few datasheets for similar devices and no place that sells just a serial backpack for such a large device. Anyone know where I can get...

Well, we got some down onto the boards. As previously suggested we followed the manufacturers soldering guide. Although at one point the reflow machine got to 280 degrees C :/ Thankfully the SCP seemed unaffected and is working beautifully.

Good Luck!

E.O.T.

Thanks for the idea, we were consulting that guide whilst we were having a go. I was just after any suggestions or experiences from the Sparkfun team themselves (assuming they made the breakout boards in house).

Cheers anyway.

Reflowing with SCP1000

Hi there, I've successfully used the SCP1000 pressure sensor that came on a SF protoboard in one of my projects at work. Now we're trying to reflow some new sensors onto our PCBs. Would any of the guys at SF, be able to suggest reflow profiles, solder/paste tips on how to get it to reflow well? Sugg...

Thanks for the suggestion, I realised that a short while after sending the post. All is well now and getting about 98kPa on a sunny day.

Ta. :wink:

Can someone check my code?

Hi again, I've decided to pick up the code again and I've realised that after all this time, I've been looking in the wrong registers! :roll: I've now got working register result fetching code. But when I try to follow the C example off the VTI website, I get Pressure results that are 1x10^9! :( :? ...

Playing with the SCP1000

Hi all, First time in the forums, but have been following the site for a while. Keep up the good work! I'm trying to get a PIC24 talking to a VTI SCP1000 barometric pressure sensor. I've used the code samples from this forum, VTI and other sources to try and clobber something together using the Hi-t...
