    Dear Stephanie,
    This is my very first comment on a personal website ever–but yours is so great I am moved to overcome my general (and problematic) lack of engagement with the world and record this moment. I might-should-not write this in your guestbook but you can choose to erase it. Your website (which is extremely impressive for its incredible variety and expertise) is amazing. But then again, so are you. Having known you for about 14 years now (it is Sasha and Ivan’s mommy writing here), I can’t say I am surprised at how cool your site is, but I am nonetheless amazed. You rock girl!!!

    Great web site! I stumbled in searching for HP200LX. I have 8, use one daily, and others for backups. I love them! I got my first one in ’94 from a friend who wrote software on one to use for weather info transfer via ham radio to hot air balloons.

    Good to see someone who has spent the time to write up how good these are!

  3. Stephanie says:

    Thanks for the comments Joe!

    That’s one of the things with using ‘obsolete’ gear, you have to be your own repair shop and parts-depot. I have about 4 of the HP palmtops, one for use and the rest for parts / backups. And I still have 2 or 3 newton 2100s for the same reason.

    Although I don’t use my 200LX any more, I’m still very fond of it. It’s a great machine and there’s things it can do that you still can’t do with the latest modern PDAs.

    Cheers & 73!

    Blessed be Stephanie! I just downloaded your app; the wiccan bible. Thank you so much!!! I love it! So, looking through it a bit, I decided to check out your site. So, here I am still looking and I love it, too!

    Anyway, I just wanted to say hello to a sistawitch, and say thank you for the fantastic app!

    Blessed be, and merry meet by cyber or anyway again!

    Take care.

    We have so much in common it freaks me out a little. Don’t even know where to start. But, must say when I saw the “nothing like a depressant to chase the blues away” quote I almost fell out of my chair. You have no idea how often I say that. (hmmm, note to self, maybe that is a bad sign, follow up on that later)

    Anyway, love your site. Thanks so much for sharing your … Knowledge? Passion? Obsessions? Whatever you want to call it, it’s all great.

    Came across your site while doing research on watch making. SM#1 and SM#2 are beautiful. Well done. I am just starting a project to make a watch for a friend’s birthday. (Am enrolled in the tz1 class.). Would really appreciate advice on making the watch face. What you did with the Vostok font is great. How did you start?

    Please help. I’d be forever indebted.

    Your newest fan.


    1. Stephanie says:

      Hello Peter, thank you for your comments!

      I did the watch face design in a vector-based drawing program. To start with it was some boring and repetative work to set up the ‘notches’ around the face. Create a line, duplicate it, rotate n degrees, lather, rinse, repeat. Then I saved that as my ‘template’ so I wouldn’t have to go through all that again. Once that was done, it’s easy to just modify that template to come up with the different designs. To make my name in Cyrillic ‘font’ I actually ended up drawing each letter (boxes and lines) to get the look I wanted. (I couldn’t find a Cyrillic font I really liked, at the time, and it was easy enough to make my name with block letters.)

      Once I had a design I liked, to get it into the watch I did a lot of experimentation before I found an easy shortcut method. For the first design, I printed the watch face at 1:1 scale using a laser printer and pressure-sensitive label stock. The laser printer coverage wasn’t 100% perfect, so I touched it up with a permanent black marker. Then I cut it out, peeled off the backing and stuck it on the blank watch face. I had to do this 3 or 4 times before I got it perfect – it wasn’t easy to get it lined up 100% right, but I had printed lots of extra faces knowing it might take a few attempts.

      For the one-handed watch, I used a colour bubble-jet printer as I wanted the face to be blue-on-white. My bubble-jet wasn’t great for full-coverage so I designed the face accordingly, with more whitespace. That way the risk of imperfections in the printing process was minimized. As with the previous watch, I made a number of copies of the face, so I had several chances to get the label onto the watch blank.

    I saw your thermostat on HaD and thought to myself “Self, you need a thermostat you have an Arduino and an old Nokia cellphone to cannibalize the display from”
    Keep up the good work and look up to the skies, just in case .

    1. Stephanie says:

      Hello Matt,

      Thanks for comenting! The thermostat has been a fun project and I’m still looking at ways to improve it or expand on the functions.

      I’m also thinking of setting up a ‘how-to’ page for it, if I can get myself organized…


  7. Carl says:

    Thanks for including the programming files for your beacon. Im just learning PIC PROGRAMMING and your program will assist me with the learning progres..



    1. Stephanie says:

      Hi Carl, thanks for the comment!

      I hate to admit it but I’ve forgotten almost everything I knew about PIC coding, it’s been so long since I worked with it. I’ve been thinking of redoing the beacon controller as an Arduino project instead, as it’s a much easier & friendlier environment then PIC assembly. 🙂

      Cheers & 73!

    Dear Stephanie,

    I have never considered Witchcraft before now. I am going through yet another period of unbearable sadness and despair to the point I no longer have the will to go on.

    Browsing the Internet, I found a Knot Money Spell which reminds me of your Cord Spell in Liber Umbrarum et Lux. The knots, however, are tied in a different order:

    I believe I have an extraordinarly good heart, open mind and total faith. Prayers and Novenas to God, Jesus, Mary and the Saints have never, ever worked (including pilgrimages, sacraments, rosaries, holy water, etc.) so I am counting on Magic to transform me and my life for good.

    Would it be possible to send me positive energy and cast a spell to strengthen my weak mind and sensitive heart?

    Merry Meet & Blessed be,

    An Aspiring Witch in Toronto

    Hi Stephanie,
    i found the dual boot loader for the dingoo A330, great work,
    does this loader also work on a dingoo tech. A380??
    kind regards

    1. Stephanie says:

      Hello Daniel,

      I really don’t know, sorry. I haven’t been involved with the Dingoo comunity or development for over a year now.

      You could try checking out the forums at – thats where I used to hang out and they were a fairly active community, with some very knowledgable folks.


  10. Pete says:

    Am interested in building out the thermostat. But am confused on what is needed. Don’t see a bill of materials to build it form. Any help here would be greatly appreciated.

    1. Stephanie says:

      Hello Pete,

      Yeah, about that… my apologies, as I never did get around to a full write-up of the thermostat project. It was covered in a lot of step-by-step blog entries; there’s about 2 pages of entries under the thermostat tag that sort of cover it:

      It’s (still) on my to-do list to do a proper writeup, especially since I rebuilt the thermostat at some point over the summer and didn’t even mention that in the blog, I think.

      In brief though, it’s an arduino, a DS1307, an XBee, a LCD screen, a handful of pushbuttons and switches, and a temperature sensor. And a couple relays, to control the furnace and a/c. There’s actually not much to a thermostat, really.

  11. Ken Scharf says:

    Congrats on your thermostat being on the Adafruit blog. Nice looking project that covers an ugly hole in the wall. Why can’t you steal the power from the AC unit? Most AC thermostat interfaces have some LV AC or DC available that could run the electronics. Might have to supply a rectifier, filter and voltage regulator though.

    1. Stephanie says:

      Hello Ken, thanks for the comments!

      I’ve done some research on trying to find out how to tap into any excess power available through those lines, but have not been able to find anything specific or pertaining directly to my A/C unit. Without knowing enough about it, I confess I’m a bit afraid to mess with it as I absolutely cannot afford to get it repaired if I damage it. 🙂 Not to mention, my basement is a dank and terrible place so I try and avoid going down there unless absolutely necessary hehe.

      I think what I may do is just make a small hole down at the baseboard (there is a sofa right there so it would be hidden) and run my DC power wire up behind the wall from the baseboard to the thermostat.


      1. Ken Scharf says:

        Use a ‘bell hanger’ bit to drill down from the therostat hole to the base board. Sometimes there are cross braces in the wall. The bit has a long shaft (6′ or more!) and is flexible. The tip has a hole so it can be used as a fish to pull wires though the wall. Homedepot should have them. If you don’t have any cross braces then a common electricians fishtape line will do. If you only had the original thermostat it was probably labeled as to which wires were the LVAC feed.

    hello stephanie,
    i got your app and am studying it. I wanted to warn you of a shadow that is pretty powerful. it’s from seattle.

    Stephanie, I enjoyed browsing your site! you are an interesting person with many good & useful talents! I think that we share many interests and attributes – who knows, we might be friends some day…
    I noticed your quote from ‘we might be giants’ – as it happens, I grew up next door to the the Flansburghs (John & Sky), and was friends with several of the Linnels (sp?).
    funny world

    1. Stephanie says:

      Hello John, thank you for writing!

      The site is in a state of flux at the moment, the dust still settling as part of a major overhaul that isn’t entirely finished yet.

      I’ve been a fan of TMBG for over 20 years; I can only assume / hope that they were fun to know and live near 😀


  15. Ryan Vytlacil says:


    I saw your post about the multifunctional wristband that includes GPS readouts. I think its super cool.

    In the comments you wrote that you intended to do a block diagram. Did you ever get around to that? If so, I would love to see it.

    Thank you much,


    1. Stephanie says:

      Hello Ryan,

      Sigh… I never finished that project. The first version was finished and there was a block diagram for that, maybe that’s what you’re looking for?

      I was working on a complete overhaul with a custom pcb and way more functions etc. last year but I just ran out of steam and money and enthusiasm before it was finished. It’s still in my project pile, I’ll get back to it… some day.

  16. Xavier says:


    I would like to build a gps. Could you send me a list of components?
    Another question: Is posssível track the GPS signal via google maps?



  17. Xavier says:

    Hello Stephanie!

    I wonder if to receive the signal from GPS Latitude and Longitude is necessarily needed a sim card?
    From what I understand your GPS wrist requires no sim card. Yet it is possible through software, monitor the location?



  18. Andrew says:

    Hi Stephanie!

    I’m sorry about the passing of your father, and I understand if you don’t answer this question. I’ve been working on your ISEB6 for a few weeks. I’ve been able to get a few sensors to work with a newer version of the OLED you used. So now, I was wondering how you sew the bracer, like what design you had in mind? all of the bracers I have seen were medieval cosplay kinds.

    Thank you!

    1. Stephanie says:

      Hello Andrew,

      I never finished the last version of the ISEB, primarily because I couldn’t quite get the final enclosure and wrist connection “just right”.

      The design I was working on was a sort of H shape, where the two upright parts of the H were like the bands of a wrist watch, and the horizontal bar of the H was where the ISEB was mounted.

      I made a few versions out of a soft pliable leather, and while they did work pretty good, I couldn’t quite get the leather correctly mated to the electronics.

      In recent weeks I have been looking at it again (after a 2 year hiatus) and I think it might actually work if one could 3d-print an enclosure, perhaps with mounting holes to bolt or rivet the leather bands to.

      The original prototype was quite medieval in style I think. It was about a pound of ugly hard leather, but it did incorporate some steel bands so it actually worked as bit of armour in addition to being an electronic enhancement.

      1. Andrew says:

        Would the 3d printed enclosure replace the multiple leather panels?

        1. Stephanie says:

          Yes that is how I’d do it. Bear in mind, I don’t have any experience with 3d-printing… but from what I’ve seen I think it would be ideal.

          2 years ago, I was planning to construct the enclosure out of a sheet of very thin brass. But I couldn’t get it to fold right (I don’t have access to any shop equipment just household stuff) and it tarnished too easily, and I wasn’t sure how to mate it to the leather straps,

          Now, I’d make the enclosure with some holes along the ‘top’ and ‘bottom’ edges, I.E. to line up with the horizontal bar in the H shaped leather, then use little rivets or similar, to secure the enclosure to the leather.

          Sort of like, the enclosure is the top half, and the leather is the bottom half. The enclosure (3d printed or made of metal) would be the top, and sides. The electronics package would drop inside and then be held in place by the leather underneath.

          So no layers of thick leather, just the two ‘watch bands’ connected in the middle.

    Wow, do you know Solaris Blueraven??

    Anyway, I am having trouble getting your liquidtwi to incorporate into my Arduino 1.0.5 IDE.

    I try to use the “add library” function which has worked on other libraries for me.

    Not sure what I am doing wrong.

    Thanks for any help.

    You ARE popular on ADAFRUIT!!!!

    1. Stephanie says:

      Hello Jeff,

      I don’t know Solaris Blueraven, sorry.

      Re. the LiquidTWI library, it has been a while since I’ve been very active with Arduino, but I did happen to use the library about 2 months go on a small project and it worked ok for me.

      So first, here’s the most up-to-date version. I don’t know that it’s changed any, but best to make certain we’re both using the same version:

      Next, the library is only tested with the Atmega Arduinos – not the newer ARM ones. It should work with Mega, Leonardo, Uno, anything based on the Atmel Atmega chips.

      Finally, with Arduino 1.0.5 I have my libraries in a subdirectory with my sketches. So wherever your sketches are, you’d add a directory there called “libraries’ then inside that, add the LiquidTWI directory. (Restart the Arduino IDE so it recognizes the new library.)

      Oh and finally finally, if you are using something other than an Uno, make sure you are connecting to the correct I2C pins. They are A4/A5 on the Uno, but they are different on the Mega and on the Leonardo.


  20. cyberocker says:

    I happened to come a cross a link to your Handspring Visor pages, and could not pass up an opportunity to request help for a long term project of mine…

    I am looking for the software that came with Handspring Springboard development PCB (from efig, I think)
    I am hoping I can find someone that can supply me with the support software, as I have the Diagnostic Reference Module, but not the supporting DiagRefModule sample code.

    (I found a reference to it here-
    under the Software heading).

    I hope someone can help me; I want to develop a temperature based controller for several applications (greenhouse, battery charger, etc.) and would like any help that others might want to contribute, so email me, if your interested…

    1. Stephanie says:

      Hi Cyberocker, thanks for writing.

      Unfortunately the Visor stuff was all… 13 or 14 years ago I think, and I don’t think I have anything remaining from back then. In my Visor hobbying around I never did any development at all, and for the two months or so I was involved in an actual dev project, I was on hardware. I don’t remember having any of the SDK myself.

      If I do come across something I’ll post it.
