content: So I was thinking. I know, no jokes please.....I am sure that many people have needed a single part, or some strange part you can only find on broker sites that aren't available anymore except from these parts brokers. I have run into this myself a couple of times. Ebay is an option sometimes if you have confidence in the seller but sometimes it just is not cost effective nor necessarily a trustworthy seller.So the idea is that I think we should have a trade thread. If you need something one off, hard to find, then post here to get someone to donate the part if they have it or maybe trade for it. If you have some random part or a pile of them, offer them up here for grabs. Please no sales and purchases here, just trades or free offers for requests. Please also make sure to post your request for postage costs if you want them.So pay it forward! Lets trade some parts or just outright give them to those who need them. If you receive something, remember this and make sure you give back to the community.As suggested by Dave (the member not the admin) and Tautech, this thread could get messy. In light of this please maintain your posts. Update (modify) your posts to reflect what is available or not, and what is needed or not. Please search the thread for the relevant parts needed or offered before posting a new one for the same part. Thank you.

content: I like the idea, but I think you'd need a large spreadsheet of what is being offered and by whom, as well as quantities and it might be a good idea to add another box that gives a short description of the component. The forum thread alone would get cluttered in a heartbeat, it would be impossible to keep track of offered components.Might not be a bad idea to have several spreadsheets for different types of components.

If this gets out of hand, so be it!I don't think it too hard for people to search first for a post and then ask again if necessary. If it is too much work to search for themselves for something that is free, "No parts for you!"

I am sorry but really?If you have any junk equipment lying around, anything, it probably has something close if not a 1k resistor that you can salvage. These also can be had a many electronics ships for less than postage from almost anywhere. This is not what I would call a hard to find part nor even cost effective to mail.Really?

content: Well, I was expecting a Tenma Soldering station from a forum member. He is in the northern part of my state and said it shipped out on the 22nd of March. Oddly I still haven't received it and he hasn't been active in a week. The last message I sent was voicing concern for the delay and our terrible Postal Service. At this point though, I am starting to worry about him. I hope all is well with this fellow EEVblogger! I'm holding out hope that it is nothing at all...As for what we may need, an oscilloscope would be fantastic. However, we are very wet behind the ears in the electronics department and open to suggestions!Thanks for any support!

Even a monochome Tek TDS 510/520 would be very useful for you.Good luck with your hunt for goodies.

I am a student looking to build a "lab" of my own so to say (a sucky lab, but a lab), and something like this would be of great help, considering I am not exactly old enough to do most work, and as a result it is hard to earn moneyI know this is probably a pretty big request for this thread, but it never hurts to ask

content: Quote from: apelly on March 01, 2015, 11:26:11 pmI don't have any info, got them as a box of junk. They look to be modules out of laser pointers.There are two types. One has a boost converter and can run from like 0.8V The other needs 2.5V.Max is probably ~4.5V. but i only figured that by the fact that they smoke at 6VThey are all red lasers and one type can be refocused (other is glued).

content: Psi, I too would like a few of those laser diodes if they are still going. I'm into replica prop making and recently started looking into Predator weapons (specifically the shoulder mounted cannon/helm laser combo). Those diodes would be perfect for trying out the triangulation machanism I have planned for the bio helmetAs a contribution, I'd also like to throw some items up for offer starting with Vishay P16 10k pots. While not so hard to find, they are in the "rather expensive to buy" category for the "small of budget" hobbyist like myself.They are new "other" as I have special licence to reclaim pretty much anything from scraps to use in my own projects, and I often come across many items perfectly useable. Once items are scrapped, the company I work for just isnt interested in putting the recovered items back in the system, even though 98% of the time there's nothing wrong with them and I am able to do as I please with all approved recoverable items, hence the offer.I have 5 pairs of pots on hand to give away now, and will most likely have more in the future (the nature of production I guess) so will update as things progress.

I also have a Conar 255 solid state CRO that I built as part of an NRI course back in 1978 and a Heathkit 10-4101 electronic switch that will put 2 traces on the scope. They both look like new and work perfectly. You are welcome to the scope and the switch and also the soldering station if you haven't received the Tenma.I live in South Bend and even this close to you the shipping charges would be more than the equipment is worth. If you can wait until the end of this month we are having an Anniversary celebration on the 25th of April and my wife's sister who lives in Fishers will be coming to South Bend. I can put the equipment in her trunk and give you her phone number and you could arrange to meet to make the pickup.If you are interested let me know and I will PM her phone number.

content: This is a good idea, I have some now unused test equipment to be given away.But!Does it have to work? It did many years ago when I last tested it, was listed on ebay to sell but didn't. Whilst I can drag it out and power it up, what if it doesn't at least mostly work? I really can't see someone new to electronics delving inside a scope. And the time taken to fault find probably isn't on either.Have done quite a bit of searching on donating equipment and not really come across an answer. What is the general opinion please?As to the gold digger problem. Do charity shops give receipts for donations? If I send a scope, paying the delivery charges, then the recipient paying a suitable donation to a charity and then posting the receipt on here?

content: Quote from: woodchips on April 08, 2015, 09:03:07 amIf it's untested say so, but it's a nice gesture if you are wanting them to donate to charity or pay shipping to power it on and let it run for a few hours and check basic functionality.A charity will give a receipt if asked. I think you're better just to ask for shipping first and then donate it to charity if you want to go that way.Regarding the gold digger, there is something to be said for fostering community, but it's little silly so called beginners are asking for an oscilloscope before they even show the slightest interest in learning about hobby electronics or electronics engineering and basic skills like using a multimeter, soldering and building or simulating a few simple circuits. Asking a few questions up front never hurt anyone either.

I was wondering if anyone in the UK (specifically St Neots or Cambridge) had any surplus cables or connectors they could give away (for a cost of course). Things like BNC cables, 50 ohm termination etc. I know they are cheap on eBay, but you never have the right lead, and the cost adds up when you have so many different variations. Thanks to anyone who can help!
