Re: Current and Voltage Logger

I'd like something that I can include with the circuit (taped to it). Some of the projects go out in the forest and some I want to monitor for a week or two.

Current and Voltage Logger

Hi all, I build a lot of small battery operated circuits and would like to log how much voltage and current they use. Is there something already built that will do this for me? If not, how can I test the voltage and current use of the battery without depleted it any.

Denis.

Thanks, those should do! I might still pickup some wire glue to try it out.

Re: Conductive Glue for Terminal Coating

Oh ok, I'm looking for the coil type springs. Those don't have then, just the tab-type springs. Maybe I can use those ipad pens that have the rubber tips at the end. I hear those are conductive. I'll have to measure their resistance tomorrow. I could use on to cover the tip of the coil-spring. I cou...

Re: Conductive Glue for Terminal Coating

I don't think that would work into my current design. Do you think they make stainless steel springs? I tried looking it up on Digikey, but they only have nickel-coated spring steel.

Re: Communication Protocols

I guess, I didn't ask the question correctly. I'm just wondering about the programming side of things. We already use a solution to read/write RFID tags, but still need to communicate with it with our processor. They lay out the way to communicate with their module in their manual. I looking for som...

Re: Conductive Glue for Terminal Coating

I don't have a battery in there now. It's just the terminals. The battery gets inserted for about 5 minutes every month. The flashlight is not really a flashlight anymore. Just a case for my electronics. The flashlight is inside of a small plastic peanut butter container with those thick twist on ca...

Conductive Glue for Terminal Coating

Hi all, I have a outdoor project that required people to insert a AA battery to work it. I do this so that there's no power issue with lasting a long time without being serviced. What I've found is that the battery terminals (flat metal piece and spring) end up rusting making it difficult for people...

Communication Protocols

Hi, I find my self having problems when I have to write software for communication protocols. I was wondering if anyone had any tutorials or tips for writing such things. The language would be C. I was trying to write one for an RFID module that we use here at work. They lay out the comms in the man...

Electronic Stores Nearby

Hi, I'm always travelling in the states for business. I usually find myself wanting to play with electronics or wanting to pickup some components for when I get home. So I google for the nearest electronic store and usually find industrial electronics and stereo businesses. Are there any good electr...

Re: LCD Connector Pins

I wanted to mount dollar store lcd's so that they would be easy for my to put into my projects. My projects are usually one-of's and I can't find lcd's that are really small on Digikey or Mouser. The 2x16 lcd's are bigger than I'd like to use. The dollar store ones usually come with the conductive r...

LCD Connector Pins

Hi, does anyone know where I can get the pins in the attached picture? I can find them on DigiKey or anywhere else.
I guess I can't get the file upload to work. Here's the link to the image: http://www.altadox.com/lcd/images/lcd_connector_pin.jpg

Thanks,

Re: Dollar Store LCD displays

Basically I wanted it to be small and cheap. The ones that are linked above (~$3) are big and bulky. I have two, one with the sparkfun serial board and one without. The one I got from the dollar store is tiny and displays all the digits I need. I just needed to know how to control it. I'm planning t...

Re: Dollar Store LCD displays

Ok, so I will try to find an already made one. I looked at Digikey and Mouse, but could only find the display and not the controlling board. You said in previous posts that I was trying to save a buck or two. Where can I find these $3 displays?

Thanks,
Denis.
