Show HN: Berlin Swapfest – Electronics flea market
Hey HN,
After scrounging the local classifieds and our version of Craigslist to find pre-owned equipment and getting frustrated I decided that there needs to be a flea market but for electronics tools and homelab stuff. The Berlin Swapfest follows in the same spirit as the MIT Swapfest!
I’ve partners with a long time hacker space in Berlin c-base who will be hosting this event!
Would love for local hackers to come by and buy and sell their old gear!
Details on the site!
- KeplerBoy 2y agoNever heard of having to register in order to visit a flea market as a potential customer.
- mirshko 2y agoIt’s mainly to figure out how many people are coming! We have limited space at c-base and I want to be respectful of their fire code!
- JTyQZSnP3cQGa8B 2y agoThat makes sense. Where I live the large flea markets always have 1 or 2 local cops, and maybe a fireman to handle any emergency.
- ibeff 2y agothe berlin hackerspace scene would not allow police at their events
- KeplerBoy 2y agoSounds reasonable, especially for the first time such an event is held.

- nhatcher 2y agoWoah, this is a great initiative! I hope it works out. I regrettably will not be in Berlin that day. It is really hard to get second hand electronics and equipment in this city if you don't want to go online. Sign me up for the next one!
- dcminter 2y agoI've always wondered about the risk of expensive-to-dispose-of bulky waste ending up on site if the sellers can't sell - looks like you've taken account of that with the deposit system already though. Hope it goes really well!
- mirshko 2y agoThanks! Yeah c-base crew was incredibly adamant about that, they used to have people leaving stuff there or bringing them electronics, they’ve got closets of switches. As you said the deposit will handle it, worst case if someone brings a 19” rack that will be used to bring it to the tip
- saidinesh5 2y agoNice website design - with the tearaway papers to download... Would love to see a follow-up on what interesting items were brought there... Good luck!
- mirshko 2y agoThat was our designers idea! Will pass on the nice words. Also will try to have someone taking photos to document it. Our event person at c-base ligi also suggested to idea of having a small show and tell time permitting for really cool items that have a story to them.

- progbits 2y agoNice! Might travel to Berlin for this. Any idea how non-german-speaker friendly this will be? The hackerspace website is german only, but I'm hoping we can expect most attendees / sellers to speak english?
- internet101010 2y agoYou'll be fine. Worst case scenario have the calculator on your phone ready to type in numbers.
- mirshko 2y agoI’m an English native with A2 German at best and have no troubles there! A majority of events are in English there, one tonight was all in English as well.
- progbits 2y agoAwesome, thanks!
- Havoc 2y agoBig city + tech focus - I'd be surprised if you can find someone that doesn't speak functional English.
- herval 2y agoBerlin is still the ultimate hacker city. Great initiative!
- neilv 2y agoRelated events in other cities? To start: * US Boston / New England area -- MIT Swapfest, http://w1mx.mit.edu/flea-at-mit/ http://w1mx.mit.edu/flea-at-mit/
- mirshko 2y agoThat’s where I got the idea! I was blown away at how cool that event was, I emailed with their team to get some tips for it as well. The coolest part was someone brought a Gemini lander to sell!
- nis0s 2y agoOnce at an MIT swapfest, I paid someone half price for a camera to “hold it” because I didn’t have the entire amount they wanted in cash, and they wouldn’t take Venmo. I never got the camera or any money back because he basically gave me the run around. Silly me believes in being virtuous in casual transactions.
- neilv 2y agoSorry that's happened. How long ago? Do you think there's a chance it might still be straightened out? BTW, you probably know this, but just for HN: some of the vendors and shoppers will be calibrated a bit differently than average, so there might be miscommunication, or awkwardness, or different conventions, to get past. A few years ago at Swapfest, a friend and I met up there, as vendors were packing up, and one of the vendors in the parking garage was having trouble starting their truck, dead battery. So, maybe because my friend thought the vendor might be averse to asking for help, she quietly went and asked another nearby vendor with a vehicle, if they could give a jump, and they cheerfully did. (Friend is a former military officer, who had also gone to MIT, and who exemplifies some of the best of tech industry leadership, including Knowing Your Nerds.)
- nis0s 2y agoI didn’t mean any shade at MIT, or the MIT swapfest—I was just sharing a story. I also met some great people there, and bought some cool stuff, so I’d highly recommend people in the area to attend it at least once. Regarding trying to sort the camera thing, it’s long past now, and I don’t care. Maybe they really needed that money.
- michaljanocko 2y agoAlready registered! I just happen to be visiting Berlin with my girlfriend on that day so I'll try and clear out some inventory (depends on the size of our backpacks and the amount we can take on the train). Thank you for organizing!
- lelandfe 2y agoReally dig that clicking the dates "tears" it off and downloads an event.
- Philpax 2y agoMan, I remember going to swapmeets as a kid in 00s Australia. Online shopping killed it then, but I'm happy to see it make a comeback in one way or another - I have fond memories of meeting other enthusiasts and admiring hardware old and new :)
- doctor_radium 2y agoGood luck with the swapfest! Back in the day I loved to visit these kinds of shows in the Timmonium, Maryland area. Went to Gaithersburg once, too. If you were motivated to dig through cardboard boxes of cables and miscellaneous stuff, you could spend the entire day there. But as the internet grew they got smaller every year, to the degree that there wasn't much of a point anymore. While I never got to one, I recall Columbus, Ohio having the biggest show in the mid-Atlantic. Wonder if they're still a thing?
- doctor_radium 2y agoEdit: Dayton, not Columbus. And as it's slightly on topic, a brief humorous story. At least one of the two annual Timonium shows was sponsored by the local Ham Radio (amateur radio) club. This was common because (I suppose) the radio clubs were typically bigger and more organized than the computer clubs. When I was in my 20's it was a rite of passage for some of my friends to get their Ham Radio license. Fast forward to around 2007 and my sister and I are driving to Phoenixville in eastern Pennsylvania for Blobfest. Getting off topic, but it's an annual celebration of the classic 1958 sci-fi/horror film The Blob. On the way back I notice a sign on the side of the road that reads "Ham Fest Today". I go a little crazy, telling my sister, "Turn there! Turn there!! I have to see this!!!" We turn and it's a bust. The show was the previous weekend and somebody forgot to take down the sign. We get back on the road. About a minute later she turns to me, completely innocently and wide-eyed, saying, "I had NO IDEA how much you liked ham!"
- dunham 2y agoMy Dad took me to the Dayton, Ohio Hamvention a few times back in the late 80's/early 90's. It looks like they still exist. I didn't really have a lot of money to spend, but it was fun experiencing the culture and looking at all of the neat toys/junk.
- NetOpWibby 2y agoThis sounds dope af. Also happy to see people here in the comments sharing similar events in their cities. Kinda encouraging me to clear out my garage to bring new junk, err, stuff in there.
- satyamkapoor 2y agoGood luck! Waiting for this to be hosted in Frankfurt. Good luck!
- pfoof 2y agoWould love to take part in this, but the date is unfortunately pretty unfavorable for me, do you have any social page to follow for the next events?
- mirshko 2y agoUpdate: https://bsky.app/profile/swapfest.berlin https://bsky.app/profile/swapfest.berlin We’ll be using this microsite for now for updates, but will likely spin up a bluesky account for the swapfest!
- gigatexal 2y agoC-base is easily one of the coolest places in Berlin! I’m so going. Maybe I can grab a well loved laptop (sure I can get one from eBay, but this way I can give money to a fellow Berlin, c-base friend).
- kaizenb 2y agoyes yes yes!
- olelele 2y agoWill be booking a table asap! Have a bunch of stuff that can move on :)
- Towaway69 2y agoIt’s moments like these that I hate being a hoarder - just can’t let go of the dusty old gear lying around ;) Btw one could get company sponsorship for a ewaste container so that one doesn’t have to take stuff back home - after all it’s the big companies that produce this stuff and then make it redundant. Perhaps ewaste could be segregated by company to see who is the biggest “offender” - I’m sure there’s many a Fritz box lying around…
- saddat 2y agoBack I my days, on electronics or computer fairs , there were “trash seller” , where you could buy non-working equipment by weight , and we repaired some at home
- hypercube33 2y agoI remember going to basically a traveling flea market of computer stuff that was hosted at our state fair. Endless vendors were there selling new and used items. Some were sketchy some over the top legit seeming. Felt like computer shopper magazine in real life.
- ilikegreen 2y agoThis looks really cool! Might do a few hours travel to join. I did not know about c-base either. Are there similar associations throughout Europe? I'd love to join one — seems to have a very cool hacker-y spirit :)
- _tk_ 2y agoThese are the ones affiliated with CCC in Germany: https://www.ccc.de/en/club/erfas https://www.ccc.de/en/club/erfas
- miduil 2y agoYes! There are several others even in Berlin, some of which are much more welcoming than c-base. Generally you can find some sort of space in nearly every city. https://wiki.hackerspaces.org/List_of_Hackerspaces https://wiki.hackerspaces.org/List_of_Hackerspaces https://web.archive.org/web/20250214091402/https://wiki.hackerspaces.org/List_of_Hackerspaces https://web.archive.org/web/20250214091402/https://wiki.hack...

- manish_gill 2y agoIf there are any of these hacker spaces that are friendly for English speakers (my German is only A2.1 sadly), I would love to join one of them :)
- chabes 2y agoThanks for this. I’m planning a tour of hacker spaces, maker spaces, and any DIY-related places across Europe in April and May. Will definitely be using this for my research. If you have any other recommendations for Berlin and surrounding areas, I’d love to hear them.
- lippihom 2y agoWhich other ones in Berlin would you recommend?
- larusso 2y agoThis sounds awesome. But it’s sadly the Easter weekend. Family has other plans on this longer weekend.
- clausecker 2y agoSame here. What a shame.
- Luc 2y ago> find pre-owned equipment and getting frustrated That's the problem - in the US there's an abundance of surplus electronics equipment at low prices. In Europe there isn't, and it's priced too high. I.e. the problem is not the market venue, it's the amount of available stuff.
- lnsru 2y agoBerlin is special place. You can find there all kinds of awkward Soviet or German Democratic Republic gear. I don’t know what for though. It has no sentimental value for me and for real work it is mostly useless in 2025.
- FirmwareBurner 2y ago>I.e. the problem is not the market venue, it's the amount of available stuff. Which is a direct consequence of the local purchasing power and consumer spending habits. Consumer electronics are cheaper in the US, and Americans have a lot more disposable income and a lot more inclination to buy into the latest trend or to experiment with latest and greatest gadgets, even if they don't need it so the used market is full of great stuff at bangout prices. Consumer electronics cost more in Europe and Europeans are also poorer and need to be more frugal with their spending so the used market has fewer new stuff at rock bottom prices.
- miunau 2y agoCurious conclusions. Which data do you base this on? US median income is 5th in the world. There's Luxembourg, Norway and Switzerland before it. Consumer electronics are quite similarly priced in both places once you take sales tax into account in the US. Not to mention it's odd to talk about "European prices" in the first place. There's no euroblock-wide price fixing going on.
- FirmwareBurner 2y agoAverage yearly salary in the US is about 60k, while in the EU average it's about 37k so of course the US as a market has a much higher spending power than the EU. Sure, individual markets like Luxemburg and Norway might be richer than the US average but they're also orders of magnitude smaller markets than the whole US. Scale matters. Prices in the EU are higher for the same things. Why then do you think Apple launched the Vision Pro only in the US and not in Europe if you think everything is the same? Why do gaming consoles first launch in the US and only after in Europe if the market is the same according to you? It seems like the consumer electronics manufacturers know the markets better than you when they base their sales and marketing decisions. >There's no euroblock-wide price fixing going on. There is, it's called MSRP and manufactures have one for USA, Canada, EU, UK at every major product launch. https://www.reddit.com/media?url=https%3A%2F%2Fpreview.redd.it%2Fcomparing-the-launch-of-ps5-pro-with-ps4-pro-v0-l6amroofn0od1.jpeg%3Fwidth%3D1080%26crop%3Dsmart%26auto%3Dwebp%26s%3D5d53275dda48d3a500692fd7b1491ce642567e17 https://www.reddit.com/media?url=https%3A%2F%2Fpreview.redd....
- egorfine 2y agoExcellent. Registered immediately and I sure will be traveling to Berlin for this.
- manish_gill 2y agoI'm definitely gonna attend. See you there!
