Hackaday Podcast Ep15: Going Low Frequency, Robotic Machines, Disk Usage For Budgets, And Cellphones Versus Weather

Hackaday Editors Mike Szczys and Elliot Williams discuss the highlights of the great hacks from the past week. On this episode we discuss wireless charging from scratch, Etch-A-Sketch selfies, the robot arm you really should build yourself, bicycle tires and steel nuts for anti-slip footwear, and bending the piezo-electric effect to act as a VLF antenna. Plus we delve into articles you can’t miss about 5G and robot firefighting.

  1. Another great podcast, Mike and Elliot. Just curious if you guys have metrics on number of listeners? Don’t ever see too many comments left here when you post the show notes.

    Stories I really enjoyed:

    Cyphercon Badge: a tape reader? You’ve got to be kidding! Makes me think of the old card readers I used in college for submitting FORTRAN engineering programs. :-)

    Eggbot: how could we NOT like a story Elliot mentions a googleplex number of times on the podcast? ;-) Going to have to build one someday. Looks fun. Btw, kudos to Elliot for how he always engages his commenters on his articles with so many responses.

    Piezo VLF: had no idea this was possible. Always thought that VLF required ridiculous antenna lengths. Thx for sharing.

    Etch a Sketch: a true hack. Everyone loves the toy, and tying it to graphics as an output device is just plain fun.

    Analyzing Budgets w/File Tools: craziest story of the week. A true testament to people’s hacking madness demon to create something so outrageous yet so cool!

    5G Weather: another topic I wasn’t aware of and learned a lot. Again, thx for sharing.

    Hope you guys continue to do these. I’m enjoying them each week.
    🙂

    1. Not sure if it’s good or bad, but if you follow the embedded soundcloud object back to soundcloud itself, you can see how many times each podcast has been played. The few that I looked at seem to be in the 2.5 to 4k plays which I assume take into account the embedded plays (so direct from here).
      And I’ve learnt to not always trust the comments on HaD, or even the lack thereof.

      I also enjoy listening (not least to catch the latest rendition of the ‘quick-hacks’ link :-) even when I’m generally up-to-date with the updates on the main page.

      But a scuba mask on a football? O_o

      1. Thanks both for commenting! We’re having a fun time making these and glad you enjoy listening.

        As Sheldon mentioned, you can see a stream count on Soundcloud. This only shows a portion of the listens, but thus far those metrics have been a bit confusing. Depending on how we format the Direct Download link, downloads will be shown or not shown in that number. If you scroll past previous episodes you’ll see some are like 2,500 and others are closer to 5k — that’s the swing. We’re at a bit more than 20k listens a month right now that we can see form the full metrics. But it’s hard to tell which platforms everything is being counted on.

  2. Love the podcast it’s my new favorite! At about 29:11 you guys mentioned an article that sounded like it was by someone named “bob badly” about reclaiming your time? it was kind of an aside but I really want to read that article and haven’t had any success googling it, do you have a link?
