PCB making with laser printer toner
  • When making PCBs with the toner transfer method, I've used photo paper intended for inkjet printers and printed (mirrored) on it with a laser printer. Then iron the paper (printed side down) onto the PCB. Some pressure is needed but not TOO much or fine traces will squish together. Soak the board with paper stuck to it in water and then the paper can be peeled off, leaving the toner transferred to the copper. Bits of stuck paper can be removed with gentle rubbing in the water with fingers or a soft toothbrush.

    If the toner did not transfer well, it can easily be removed by cleaning with acetone, then repeat until successful. Key to getting a good toner transfer is to completely clean the copper first. I scrub with a scotchbrite pad and then clean with acetone and a paper towel, until completely clean and then don't touch the copper with your fingers (greasy greasy fingerprints). Any oils or dirt will make the toner not stick. Some paper is easier to remove from the copper after ironing on - there was a specific Staples SKU (inkjet photo paper in a red box) that I remember being particularly good. I believe the inkjet paper allowed the toner to transfer and release more cleanly, with less pressure and heat required. I also found I got a nice result using the same toner transfer method onto a block of wood (purely aesthetic, not part of a circuit haha).

    Some people would use laminator machines to "iron" the toner onto the copper board - I have never tried it that way, but I guess if you get the pressure and heat dialed in it could be pretty consistent. I've had good success using an iron by hand, after a few tries to find good temperature and pressure to apply.

    I've also milled PCBs, there are some benefits to milling, like you can drill holes at the same time. I think 2 sided PCBs are easier to mill than to etch. The limitation of milled (and etched at home) PCBs that I find most annoying is the lack of through-plated holes. This means you have to solder in wires, and solder to both sides of the board, for every via - it really adds some design limits and assembly time. Solder mask is another (optional) step, most people I know who make their own PCBs don't bother to use solder mask but it is available as UV-curable liquid.

    Ordering PCBs is incredibly inexpensive these days. Oshpark is in the USA and a great place to get PCBs. There are places in China you can order from online like PCBway, I just priced out 5 PCBs of 100mm x 100mm, 2 layers, green solder mask, $5 + $20 shipping to Canada, delivery within a week.

    Checking at a local hackerspace/makerspace is a great idea too, often there's people around who are making their own PCBs (or at least have in the past).

    I've both etched (using the laser printer toner transfer method) and milled PCBs for through hole and surface mount parts, it was no problem etching a board for a TQFP 100 pin part (0.5mm pin spacing). I didn't push it further than that.

  • bbno$ - it boy - music video shot in Cowichan, Vancouver Island
  • The teal door in a church-like building is First Memorial Funeral Services in Duncan - I had trouble identifying it also (though it had that familiar look), then on a rewatch of the video there's a moment where they show enough of the building to include the sign.

    There's also another similar coloured door + building (with coloured posts on either side of the door), the building looks more house-like than church-like. It looks like it could fit in at Whippletree Junction, but I haven't identified it as a specific building and that may not be the location at all.

    The store with the large "LIQUOR, COLD BEER & WINE SHOP" sign looks so familiar but I haven't been able to locate it yet.

    A photo I took April 2, 2024 at Cherry Point Beach, with the beached boat: Cherry Point Beach parking lot with beached boat on the shore. The boat had already been there for a few weeks by then, I don't recall exactly when it was beached.

    Went to The Brazen Fork for lunch Saturday. Selfie with The Brazen Fork sign. They hadn't seen the video yet, though they definitely recognized what I was talking about as soon as I mentioned it. They had to write down the name so they could look it up! :)

    YouTube: bbno$ - it boy (official music video)

    Watching the bbno$ video released today, "it boy", I realized (later than I'd like to admit) that it's shot in Cowichan, Vancouver Island. A lot of locations are recognizable in and around Duncan.

    When I saw bbno$ dancing on the boat, I finally clued in - that boat is beached at Cherry Point just down the road from my house! I took photos of the same beached boat.

    "The Brazen Fork" is also shown in the video, a BBQ truck on Cowichan Bay Road (great food). The falcon landing was surely shot at The Raptors near Duncan.

    There are a lot of recognizable locations from the Cowichan area. And a great song! bbno$ - it boy (official music video)

    I’m in a park. The grass is being mown by a robot.
  • It's too bad that the first things to be automated are the tasks that people don't mind doing, leaving the real shitty tasks to be done by people. Riding around on a lawnmower has to be one of the most enjoyable forms of manual labour. Now the robots get the good jobs and we're left with the backbreaking monotonous bullshit.

    SuperBBS 1.17-3 KEYGENv2 by akacastor 2024-04-10

    I've been getting into cracking DOS software, focusing on BBS software, doors, utilities, etc. My latest project is a keygen (registration # and key file generator) for SuperBBS 1.17-3. I understand that, like a lot of BBS software, the source code and registration tools for SuperBBS were lost to time. You can download SuperBBS 1.17-3 from Jason Scott's BBS Documentary website: http://software.bbsdocumentary.com/IBM/DOS/SUPERBBS/

    The keygen 'SBBSKEY2.ZIP' is available for download in file area 4 (cracks) of Another Millennium BBS, another.tel port 23.

    ``` ------------------------------------------------------------------------------- SuperBBS 1.17-3 KEYGENv2 by akacastor 2024-04-10 -------------------------------------------------------------------------------

    The SBBS-KEY keygen will generate a registration number to enter in CONFIG and a .SCC file that must be placed in the SBBS directory.

    You MUST do BOTH of:

    1. Enter Sysop Name, BBS Name, and Reg # under Registration in CONFIG.

    and

    1. Place the generated .SCC file in your SBBS directory (where BBS.EXE lives).

    The timestamp of the .SCC file cannot be altered! SuperBBS includes the .SCC file timestamp in its verification checks.

    -------------------------------------------------------------------------------

    usage: SBBS-KEY "Sysop Name" "BBS Name"

    NOTE - don't forget the quotes around each name!

    -------------------------------------------------------------------------------

    example:

    C:\CRACKS>SBBS-KEY "Sysop Name" "BBS Name"

    Making a PCB, using solder mask as etch resist.
  • Adding solder mask is an optional step. If you use an etch resist like toner or dry film, you have a functional PCB even without solder mask. The solder mask is the unnecessary step that can be skipped.

    Using solder mask as an etch resist, you would have to scrape away the remaining mask in areas where you want exposed pads - you would either need another mask for this, or to manually scrape each pad, adding an unnecessary step.

  • Baud Day 3/12/24

    IT'S BAUD DAY 3/12/24

    From the linked site:

    Something that SysOps did when they advertised their BBS. Rather than write a BBS’ supported baud rates as “300/1200/2400”, they would write “3/12/24”. The reason for this abbreviation is probably due to how BBSs were advertised back in the day. Most BBSs were advertised in text files. Depending on the host computer, a text file may have 40 or 80 characters per line. So, space was a premium and dropping 6 characters from “300/1200/2400” made a big difference.

    Saving a Buccaneer
  • Some 'getting started' suggestions:

    Telnet BBS Guide has over a thousand BBSes listed, most are accessible by telnet. Syncterm is a great terminal program for BBS use, with Linux/Mac/Windows versions available. Other telnet clients can be used, but many BBSes use ANSI and CP437 and not UTF8. (other BBSes use other standards like ATASCII or PETSCII, Syncterm supports many of these.)

    There are a bunch of interesting BBSes, one I'd recommend is 20 For Beers, connect to it at 20forbeers.com:1337. Plenty of great ANSI art and active message areas and a huge file collection too. I also recommend checking out the fsxNet message areas, they are shared across many BBSes and have an active community.

  • Saving a Buccaneer
  • This is so cool to see posted here! I'm the guy that broke my usual don't-post-on-reddit rule to share a keygen for Buccaneer. It really is a fun game, too, even if it can be a bit brutal (this is the third day in a row my ship got sunk!).

    There continues to be a thriving community of BBS users and sysops, there is a mix of new software and mods along with the old (there are CBBS systems operating - that is the original BBS software created in the late 1970s!). The fsxNet echomail network is great, linking a lot of active BBSes together and with good conversation and lots of help for retro-tech issues and projects.

    If you're interested in playing Buccaneer online, The Fool's Quarter BBS has the game online. Another interesting BBS to check out is 20 For Beers reachable via telnet at 20forbeers.com:1337.

  • Seagull on the Waterfront [OC]
  • I like this, the tilted camera adds a "fun" aspect, the low perspective captures the bird well, pretty colours in the background, the softness of the background is great as well, nice separation of foreground and background without destroying the background. Also, the bird is not smoking, so it is nice to see it following the rules. Good balance of chaos and rules. Thanks for sharing.

  • [OC] Highway
  • Very nice composition, the lines of the guard rail and of the highway trailing into the distance, the balance of the sky and the ground, mysterious beauty of the fog, the glowing sun, I really like it all. The bare trees in the near-distant fog are wonderful too.

    Thank you for sharing.

  • At what size of transistor does semiconductor manufacturing become practical for independent manufacture?
  • Sam Zeloof (http://sam.zeloof.xyz/) has been working in the area of DIY semiconductor fabrication, and has successfully fabricated working ICs (from 6 - 100 transistors). He's done an incredible job at reaching ~1970's technology levels in a home lab.

    Another example of DIY fabrication: https://hackaday.com/2010/03/10/jeri-makes-integrated-circuits/ Jeri Ellsworth made her own silicon inverter.

    These examples are still very small-scale compared to even simple microprocessors, etc - but it's fascinating to see this level of technology becoming more accessible.

    The window sill has plenty of space and is a cozy spot, directly above the baseboard heater in the space behind the couch. This is one of her favourite spots.

    Art on the beach
  • Thanks for the critique! To be honest, most of the composition was based on luck for me - I saw the artwork on the concrete wall and its position on the beach is perfect - really the artist who painted the wall deserves the most credit. I did position the art to the left side (rule of thirds), I felt that showing a bit more space gave more "on the beach" feeling. I aligned the sand with the bottom third and then the concrete slab being proportioned equally was serendipity.
