Hey man, how are ya? I'm looking to have two very small circuit boards designed of which I'll need, of course, the Gerber file, as well as the parts list (and anything else you can think of that I would need to submit to a circuit board printing company). But here's what I have.
The power source will be a 3.7 volt high drain battery, (fully charged around [url removed, login to view]), but I need the voltage out to be 3.42v. The first circuit will consist of, stepping the voltage down to [url removed, login to view] output, along with, a touch sensor activator. I purchased some stainless steel dowel (3/8"L x 3/16"D) that I was going to attach to the touch sensor manually, but I'm not committed to that. If you know of a touch sensor button that is around 1/4", that either lights up when pressed against, or not, (but preferably does), then that's ok too! The object that it's going to be placed in is round in shape, which was why I went with the dowels because even if they stick out a little bit due to something flat protruding from something round, it wouldn't expose any of the circuitry. But also, I need it to only function when it is touched directly, and not through dielectrics of any sort if possible. This isn't proximity, this is to be direct contact, again, if possible. So this will have, the usual + and - coming in, with the 3.42v+ going out to be connected to the device, triggered by the 1/4" round touch sensor. It will also need on/off capabilities such as, if the touch sensor is pressed 5 times within 2.5 seconds, the LED/LCD voltage indicator (in next paragraph) will blink three times to let the user know the device is in on/off mode. I don't know if this is standard in circuitry or not, but it will also need short circuit protection, with the LCD/LED blinking 3 times when the button is pressed, not functioning until the short is corrected. So that's the first part. Am hoping to get this as absolutely small as possible, thinking 10mm x 10mm range but whatever is necessary with "as small as possible" in mind.
Next to it, (but separately) will sit a small (preferably) 4 or 5 blue LCD or LED bar display that indicates battery life remaining. Hoping for something around the 10mm in length and 8mm in height range, but nothing greater than that. A little smaller (if possible) is ok so long as it's readable without a magnifying glass. The reason for these being separate is, I'm going to have to join them by wire, and they'll be positioned separately and set in an epoxy mold, so I need the flexibility of being able to arrange them as needed while at the same time, keeping the boards as absolutely small as possible.
If this sounds like something you'd like to tackle, and you're satisfied with the price, (I set $200 as the price), I'd love to pay ya! If you need more information, please feel free to email me @ email@example.com. Thanks very much.
