spirilis 1,264 Posted March 26, 2014 Share Posted March 26, 2014 From the other day... mouser order full of miscellaneous doodads (stocking up on both 0603 and 0805 sizes of various odd-sized capacitors, 4.7uF, 0.47uF, 0.047uF, 0.33uF, 0.033uF, 1000pF, etc) Also some inductors and high-current schottky's for future boost converter work.

yosh 121 Posted March 28, 2014 Share Posted March 28, 2014 Got some PCBs for playing with Energia's CapTouch library. First order at OshPark - nice quality, but I'm a little bit disappointed that the edges of the PCBs have these "noses". Time between uploading the files and shipping: 8 days. Time for shipping to Germany: 13 days. bluehash 1 Quote Link to post Share on other sites

yosh 121 Posted March 28, 2014 Share Posted March 28, 2014 Can you share your plans for it? This was just a first step to get started with cap touch sensing - and already got problems (see HERE). Final goal could be, that I use cap touch as a replacement for the tactile push buttons I use right now. One pro then would be, that I finally have smaller/thinner packages (OLED + MCU + ...). Right now I have two things in mind: 1) I use this cap touch PCB as an additional "layer" of my project (OLED + MCU + CapTouch) - see attached image or 2) I could put the cap touch areas on the bottom side of the MCU board (changing my MCU PCB design from THT to SMT at the moment) to save one layer (OLED + MCU/CapTouch). But first I want to see, how sensitive this is - e.g. inside an acrylic case. Quote Link to post Share on other sites
Fred 453 Posted March 28, 2014 Share Posted March 28, 2014 If the cap touch doesn't work through the acrylic case, you could always use the PCB as one side the case, with the cap touch side facing outwards, of course. I'm thinking along a Sick of Beige style with a piece of acrylic on one side and bare cap touch PCB on the other. yosh 1 Quote Link to post Share on other sites
chicken 630 Posted April 20, 2014 Author Share Posted April 20, 2014 Received a Keithley 480 Picoammeter I recently scored on Ebay for $33. Supposedly it's broken, the label says "1/5/99 meter not functioning due to discharge". But as far as I was able to test, it seems to work at least down to the 1uA range. And it's in great physical condition outside and inside, it looks cleaner in real than on the picture. Quote Link to post Share on other sites

Fred 453 Posted May 11, 2014 Share Posted May 11, 2014 Yesterday my NFC implant turned up. Still looking for someone to implant it for me. It's tricky to do yourself as you need two hands (and it goes in your hand). My wife's a doctor but refuses to do it as "it's weird, geeky and creepy". greeeg, RROMANO001, RobG and 1 other 4 Quote Link to post Share on other sites

yosh 121 Posted May 12, 2014 Share Posted May 12, 2014 Still looking for someone to implant it for me. You could go to a veterinarian who makes microchip implants for dogs or to a studio which makes transdermal implants/piercings. RROMANO001 1 Quote Link to post Share on other sites
Fred 453 Posted May 12, 2014 Share Posted May 12, 2014 I kind of agree with your wife...Well, when the Terminator turns up and someone has to go through that time portal thing with plans for John Connor embedded under their skin, you and my wife will change your tune. Unless the plans are more than 888 bytes. Then we're all done for. You could go to a veterinarian who makes microchip implants for dogs or to a studio which makes transdermal implants/piercings.Whilst it's really similar to a pet tag I don't think a vet would want to risk losing their vet licence by operating on a person. A piercer seems to be the way. I have one that's been recommended but they're closed today. Quote Link to post Share on other sites

A piercer seems to be the way. I have one that's been recommended but they're closed today. I know someone training as a vet, just asked her if she would even remotely consider implanting a chip in a human in future. I fear I will get a moderator warning if I quoted the actual response but it was a pretty resounding no Can't say the idea appeals to me personally. What are you going to use it for?

Fred 453 Posted May 12, 2014 Share Posted May 12, 2014 I've already got a Samsung Ezon lock (PIN or NFC) on my workshop. I'm sure I'll add/make more for the front door, motorbike, etc. I'd also like to auto log in to my PC at work. I was thinking of something like USB HID to type the password and write-only mass storage to set it. Maybe embed it in a keyboard. yosh 1 Quote Link to post Share on other sites
