    Electronics Parts in Calgary, Alberta ?

    It's not close enough to walk to, but 'Sphere' in British Columbia seems to have a lot of electronic components that I usually look for.

    Crt tv power problem

    If I understand you correctly, you're asking if you can take the power cord plug apart and look at the 'pins' in the plug connector to see if you can find a physical problem (maybe the 'pin's disconnected from the power cord wire). If you're not talking about opening the TV chassis (as...

    4017 IC

    I'll tell you what. I think of something I want, start researching the circuit that will get me there, then start looking for the parts, .... hours later I find what I need already fully assembled and for sale for $9.99 on eBay. Are you sure you don't want to just look for somebody who already...

    Caddx ranger 8800 home alarm system problems

    Yes, it sounds like you need to reset the system. Is the original manufacturer still in business, or do you have the original owner's manual? I'd get on-line and see if you can contact the manufacturer for the fix.

    What might this be?

    It's a landing pad for mini-space aliens. The aluminum foil is classic 'tin foil hat' protection from NSA spying. The CCTV camera is so the host Earthling can immediately post the landing to Utube so that he can get the scoop before the National Enquirer does. All the electronics you see around...

    Heatsink Mosfet

    I use nylon bolts, they stand-up to heat better than a lot of the cheap non-descript ones I sometimes find in overseas factory installations where they save money by installing the cheapest parts they can find.

    Infrared headphones idea help please

    As long as you're still in the 'idea' phase of this project, I'm wondering if you're saying the configuration of your sound system is that both the stereo and the monitor use the same infra-red transmission system? Or if you're saying the monitor uses IR headphones, and you want to send the...

    40 Floppy disks for...

    Not if they're gummed-up, as mentioned by hevans1944. $1 for 40 drink coasters ain't bad though. I usually have to buy a beer at the bar before I steal theirs.

    Wanted: Beckman 5k Model A Helipot.

    Will do. If you don't get it before you leave for the day today, you should have it in your inbox first thing tomorrow morning.

    40 Floppy disks for...

    I found a box of about 200 floppies my oldest kid left here when he moved out. I asked him if he wanted them, because he used to store a lot of information on them when he was younger. He asked me what he might want them for, seeing as to how he'd have difficulty finding a drive to use them...

    Need help for pressure sensor calibration

    Do you have any idea what you're doing? What's your Standard for these 'calibrations'? What's your pressure range and accuracy requirement? If I were you, I'd contact the manufacturer of your pressure sensors and ask for some help with this.

    Wanted: Beckman 5k Model A Helipot.

    I received your reply. I sent you a couple of private messages, on the toolbar header, click on the 'Alerts' selection to view them. If you still don't know to do that, my reply was that I'm not a business, I'm a guy that has the part you asked for. I'm not sending the part until I receive...

    You should receive an 'Alert' in the header on the right side of the forum tool bar. Click on it, and you should be able to respond to my private message post to you.

    Wanted: Beckman 5k Model A Helipot.

    I've done a lot of looking. I believe I only have one of the Beckman 5K Helipots you asked about. If you're interested, use the private message feature on this forum to contact me.

    Wanted: Beckman 5k Model A Helipot.

    I checked kellys_eye (one of this forums helpful other members). His link is to Elliot Electronics, which is a store here in Tucson, not far from where I live. They don't have a 10K. After successfully selling the 5K ohm Helipot on eBay, I dug through some more of my parts inventory. (I've...

    Controversial schematic symbol

    The way I was taught (40 some years ago), you are correct in your assumption. The straight bar is the positive, and the curved bar is the negative.

    Wanted: Beckman 5k Model A Helipot.

    Scratch that offer. When I didn't hear back I had the kids list it on eBay, sold it in 7 hours. Gone now. Feel free to use kellys_eye's helpful input.
