    HPR4556: Nitro man! RC Cars

    19-1-2026
    This show has been flagged as Clean by the host.

    Today it's a special Christmas episode, it's such a kind of part for the RC cars.
    So we're going to have to talk to them about the Metro cars.
    The Metro cars are RC cars that run off of this like 20% oil gas thing.
    So the oil is in the gas, it has a little motor and you can pay you know $800 for a motor
    or you can pay, you know, the 50 bucks for a motor.

    HPR4555: HPR Beer Garden 8 - Belgian Christmas Ales

    16-1-2026
    This show has been flagged as Clean by the host.

    Dave and Kevie bring the HPR listeners another festive edition of the Beer Garden, with the focus turning to Belgian Christmas ales. Kevie discovered a scan of the original advert in the Journal De Charleroi from 1896

    Translation: Christmas beer has arrived at the Arabian horse and the globe, these two establishments so famous for Anglaise beers. Go and taste it, because Christmas is only sold for a short time.

    In this episode Dave samples
    Baby Jesus by Brouwerij 't Verzet
    and Kevie tries out
    La Binchoise Speciale Noel
    .

    HPR4553: Nuclear Reactor Technology - Ep 4 Less Common Reactor Types

    14-1-2026
    This show has been flagged as Clean by the host.

    02 Less Common Reactor Types

    In this episode we discuss some of the less common historical reactor types.

    These are a mixture of less common commercial types and some experimental or research reactors.

    I will cover advanced or future designs in another episode.

    03 Minor Successes

    04 Magnox

    07 AGR - Advanced Gas Cooled Reactor

    10 LWGR - Light Water Graphite Moderated Reactor (RBMK)

    14 Historical Oddities or Dead Ends

    15 Organically Cooled Reactors

    16 Organically Cooled and Moderated

    48 Pros and Cons

    52 Overall

    53 Conclusion

    In this episode we discussed some of the less common historical reactor types.

    As we have seen, there have been a number of different reactor designs which were less commercially successful for one reason or another.

    Some of them may make a come back however, particularly as the basis for a small reactor.

    In the next episode we will describe fast neutron reactors.

    HPR4552: Printer Conspiracy

    13-1-2026
    This show has been flagged as Explicit by the host.

    Background

    I have a very old
    EPSON R300 inkjet printer
    It has served me well for many years. I thought it was at least 10 if not 15 years old. I got it before I even became interested in Linux. For many of those years now I have been using this printer extensively on Linux.

    It has been a really good printer and has been incredibly cheap to run. Many years ago I got a number of sets of ink for it. I think they only cost me £15! A colleague at work later on gave me more sets of ink. I ended up with a large bag full of ink cartridges which I have been working my way through ever since.

    I used the printer infrequently for many years. This is far from ideal for an ink jet printer as doing so tends to cause the ink jet nozzles to clog up. Unsurprisingly in later years it has become somewhat temperamental. The problems consisted of paper mis-feeds (Probably down to the rubber take up rollers going hard over time) and missing bits of print (This I assume due to infrequent use of the printer and age of ink jet cartridges all of which were well out of their expiration date).

    The mis-fed paper could be solved by individual feeding each sheet through the printer. The poor / missing print could be solved by a combination of running the print head clean routine or by replacing the offending cartridge.

    Latterly I had print problems again and as per usual after cleaning the heads and then finally changing the cartridge the printer resumed printing normally.

    Shortly after this I bought myself an Apple iMac mini and thought it could be useful to be able to print from it. I visited the EPSON website downloaded and installed the EPSON print driver for my trusty R300 printer.

    I tried printing from my iMac and received a warning stating something like some of the components within your printer are worn and may need servicing. I’d never seen a message like this before as I normally print using open source print drivers on Linux which never report such things.

    When I tried printing on my Apple Mac no black text was visible on the page. I tried running the head cleaning routine and this made no difference. I eventually had to resort to changing the colour of the text within the LibreOffice document. This allowed me to print text that was at least legible.

    At the time I was a little suspicious of all this as the printer had been working so well just a few days previous. I plugged my trusty printer back into my trusty PC running an old version of Ubuntu using the open source printer drivers. Fired up LibreOffice and tried to print a document. To my surprise the printout was very good. While it was not as good as when the printer was new the quality of the black and coloured text was actually very good.

    My suspicion though I can’t prove it is that the EPSON print driver has worked out that the printer is 10 plus years old and needs to be returned to EPSON for servicing (or to purchase a new printer). To ensure this the driver is crippling the output from the printer.

    The Open Source print drivers have none of the nefarious nonsense and allows the printer to operate. As I said I cannot prove any of this however I’ll leave this up to you decide what you think is going on here.

    At this point I was going to end the podcast however the story didn’t end there.

    The story continues

    My mother wanted me to print out some holiday insurance documents for her. She sent me a copy of her documents as I told her my printer was working again. The first page printed out slightly faintly but was readable the other pages seemed to print using invisible ink. I tried cleaning the heads but it made no difference. It’s looking a bit like my printer or at least the cartridge is past its expiry date.

    Clearing out our loft I found the original box for my EPSON R300 printer and discovered that it was purchased in May 2005. This means the printer is now over 20 years old! At this point I decided that it was maybe about time that I replaced our ageing printer.

    We use the printer very infrequently and rarely need colour. For this reason I decided this time to buy a laser printer since I believe these don’t tend to dry out like ink jet printers and are less likely to suffer with infrequent use. Only time will tell though I don’t expect this one to last 20 years!

    Finally after all this I am not sure if using the EPSON driver had anything to do with the final demise of my printer though who knows. As Klaatu would say I leave that up to you dear listener to decide.
