    Heat proof mains cable

    Think price, shiekh. Second, think necessity. Momma's a lot more capable of burning her power cord with a clothes iron, than a tech is with burning his soldering iron power cord. Yeah, teflon insulated wire is much more heat resistant, but it's costly, and probably considered unnecessary...

    Professional Organizations

    I'll throw-in that a lot of times organizations offer DISCOUNTS to some conferences or trade show venues, if they have influence with the organization sponsoring the event. But the boy was always offered about a 10% discount, which was peanuts. Large companies anymore usually consider paying...

    where to get blank circuit boards

    Your daughter already knows where to get them, as she has done this once before, it won't be easy for YOU to get them because manufacturers get money for recycling the copper and any other metals on them. I'd apologize and remember from now on, that electronics is not a venue to be trifled with...

    Alarm Circuit

    There are a lot of different configurations for keypads, make sure you've got the one you want.

    Conductive Grease

    Drill out the metal lug, stick a threaded rod into it, bolt the threaded rod on both sides to your test assemby. Put ring-tongue terminal lugs on the ends of your different sized wires, and bolt them to the threaded rod. As long as you've insulated the connections from ground, you should...

    "House" numbered parts

    Sonuva,.... I couldn't find your parts in my data books, so I went back to the onsemi website I was touting so recently. I got into their tech support people and they looked into your parts. They just emailed me this: 'These devices are customer made for a specific customer. All...

    "House" numbered parts

    I'm not at home (where my data books are) right now. I'll take a look-see when I get back there and let you know if I find something. The big problems I experience with some part information is: 1) Short production runs of devices they discontinue, and are only listed in one or two years...

    Conductive Grease

    Wow, I haven't worked with that high an amperage before. Have you considered just using bolts and large fork tongue lugs? Electrical switchgear uses dual-sided metal contacts, that the connector slides a mating single metal contactor in between, to make the electrical contact. Kind of like...

    Professional Organizations

    My kid joined IEEE for a few years cause he figured it'd look good on his resume. They DO have a nice magazine, but that ain't worth the dues. Unless you know of a specific need for affiliation, or a group affiliated with them that you want to chum around with locally, there's not much need to...

    "House" numbered parts

    Thanks *steve*, the guy knows what I'm looking for (and can't usually find). I've got piles of the old Motorola Data Books, but when they broke-up into ON Semiconductor and Freescale, my source for the data books dried up. I've run across a lot of the ON Semi stuff lately, I expect I'll be...

    Conductive Grease

    I'm trying to figure out your application. Dow Chemical makes a boat-load of chemicals, I buy their THERMALLY conductive grease all the time, but I'm thinking maybe you're intending to make an electrical connection for some device that you don't want to get too hot. I think you'll get some...

    Wanted: Mosfet P-CH AND N-CH

    A lot of the parts being sold out of China, are parts salvaged from boards they bought from scrapped equipment. They often work, and some are even original genuine legit parts, but they've been salvaged from used equipment. Just something to be aware of. Some company scraps several hundred of...

    "House" numbered parts

    You probably know this, but I've found several of my posts from electronicspoint on the Google search engine (that I didn't personally put there). I assumed somebody from here listed them on Google, ...but maybe the Google search engine found them itself, and just added them to it's database...

    "House" numbered parts

    Sorry it took so long to get your information. Whenever I tried in the past to get information on the ON Semiconductor website, it was a complete waste of time. They may have gotten better, yesterday I got on the stie and they had a 'live chat' feature. I had a 3-lead device marked 'J31C'...

    Metal detector circuit help.

    I know you probably already did, but recheck your wiring. Do not assume something is right, seriously look at the circuit again one more time. Often I find I made a simple wiring mistake and then ignored it while troubleshooting because I dismissed it from my mind. Do you have the correct...

    Learning Electronics as a kid......

    Tried that with my kids. The electronic toys I made for $20 were nowhere near as interesting (to them) as one of those hand-held do-hicky toys for less than half the price. Plus the cheap do-hicky toys have a lot of interesting functions. Ya gotta wanna do things yourself pretty bad, to do...

    Safety circuit PCB from a ride on mower

    Hmmm, wonder if the 'booster' pack might've fried one of the coils or coil contacts. How much 'boost' is a booster pack, anyway?

    Metal detector circuit help.

    Is your sensing coil near something metal while you're testing this?

    Learning Electronics as a kid......

    I mentioned in a previous post, I started picking the neighbors trash bins for broken electronics. Oftentimes I found I could look at the old high-heat related parts, and could tell by looking at them what was wrong. I was in gradeschool at the time. I was surprised that nobody else I knew...
