Personal pencil production plant

[Robb Godshaw] put together a pencil production line for home use. The whimsical assembly line starts with a graphite rod and extrudes clay polymer around it. From there it’s down a conveyor belt to get stamped and then into the oven made from a hacked toaster. The final step is to cut out a plug of eraser and attach it to the back-end of the pencil. This low-speed assembly line reminds us of a Rube Goldberg machine with all the wasteful steps cut out.

    They look pre-chewed.

  2. James says:

    And a little charred, but fun anyway — good work!

  3. Bob says:

    I’m sure hipsters would pay good money for pre-chewed pencils.

  4. tom alphin says:

    that is the funniest happiest little machine n the world. I want my own happy pencil machine. Does it come with a happy soundtrack?

  5. NatureTM says:

    It’s a hell of a hack, and many hacks could called useless although I still like most of them, but this just seems way too pointless. My first thought was, “I hope this guy is independently wealthy, ’cause I’d hate to think this is what he does in his spare time after work.”
    I feel so conflicted.

  6. Xeracy says:

    wow, thats fucking genius! Mad props for the time-lapse video of it in action. reminds me of a Gumby cartoon.

  7. Dan says:

    Rude Goldberk machine without the wasted steps? Oxymoron much?

  8. Decepticon says:

    It’s not ‘fully automated’ as the narrator states.

  9. Anon says:

    Wait a minute, is that tin foil holding that eraser to the pencil??

  10. Dave says:

    It looks cool (concep) kudos
    Puts smile on my face.

  11. M4CGYV3R says:

    That’s pretty damn cool. I wonder how well they write?

  12. Edward says:

    “a Rube Goldberg machine with all the wasteful steps cut out”

    Oh, you mean a machine!


  13. Mav says:

    pinching pocket loads from Ikea is far less effort ; lol

  14. Freakvault says:

    @Wait a minute, is that tin foil holding that eraser to the pencil??

    I think its aluminum tape? I wonder how good the tap holds, i know when i erase stuff i press pretty hard on my eraser.

    I wonder how much after the initial build it costs to actually make 1 pencil, if it was cheap enough and i used pencils i’d definitely would build one.

  15. andar_b says:

    Cute, but it’s less than useless, the erasers are just kinda sitting there with foil to look pretty, can’t actually use em.

    The “Just for you” is cute tho.

  16. Finger says:

    I agree, this machine doesn’t have much of a point. However, if you look at the end result, it definitely has a point.

    (coundn’t resist such a poor pun)

  17. jamieriddles says:

    thats too awesome :)

  18. Misho says:

    That’s so cute! I want one of these too, great work! :)

  19. Alfred says:

    I am skeptical as to whether it actually is automated, why the ribbon cable going into the toaster?

    looks like a movie prop :/

  20. tc says:

    the green pulley is made of clay. the paper towel roll conveyor belt is manually rolled up to make it move. As real as Bob the Builder.

    After watching this, I feel somewhat satisfied. Brought a smile to my face.

  22. brandon says:

    what’s a pencil, i mean i use pen’s, when’s the last time anyone’s ever used a pencil, other than carpentry.

  23. Gibbo says:

    Thats not fully automated?? I always like to see toaster hacks though.

  24. osgeld says:

    @brandon, draw a mildly complex schematic without making a single mistake

    I know I cant so I use a pencil

  25. willyshop says:

    Is this a joke?
    That isn’t at all automated. The whole video is stop motion animation. Am I seriously the only person who noticed this?
    And Ticonderoga isn’t an iconic phrase, it’s a brand. If you’re trying to make your own crappy pencils you might as well put your name on them.

  26. Hirudinea says:

    Easier to steal them from work.

  27. stib says:

    Uhh, the pencils are made of clay? How do you sharpen them?

  28. stib says:

    and yeah, it’s totally non-automated, it’s a stop motion movie. Calling this an automated pencil maker is like saying that this is a video deomnstrating a new display device:

  29. Hiroe says:

    What is up with that accent? I have never met somebody who has one that isn’t geeky. I would be very interested in learning the cause.

  30. R4z0r says:

    You could almost say he *Puts on sunglasses* is a pencil pusher *YEAHHHH*

  31. jrcoach says:

    Hilariously awesome.

    “That isn’t at all automated. The whole video is stop motion animation. Am I seriously the only person who noticed this?”

    Yes, you are the only super genius among us plebs who managed to notice that. Please, continue to point out your incredible insights in the future.

  32. CG says:

    I like. I guess Robb Godshaw is the next Rube Goldberg.

  33. strider_mt2k says:

    vast stationary conspiracy

  34. Robb Godshaw says:

    You are all correct. it isn’t fully automated. I suppose i misspoke, it was late when i made the video. every step requires human interaction, but it is limited to pulling levers and cranking the green plastic gear. I did not have a video camera, hence the stop motion. The final cost of each pencil is about $150, which is very impractical. the rainbow ribbon cable does nothing. The clay pencil, once baked can be sharpened normally. the eraser holds on fine, and can be used like a regular pencil. Aluminum tape is quite strong.

  35. Robb Godshaw says:

    Correction, $1.50 USD

  36. Malikaii says:

    I think you meant to say a Rube Goldberg machine with all the USEFUL steps taken out.
