Profile

Bio

Aging medical / communications applications programmer with a strong predisposition towards embedded hardware.

Role

Stealth programming consultant with strong desire to remain undisturbed in my basement.

Organizations

Not much of a joiner…

Spoken Languages

English, nothing else useful.

Programming Languages

C, C++, various ASM’s, Python, JS, others I’d prefer to forget.

Associations

Association of Persons with Dissociative Personality Disorders (ADPDP).

Universities

Various, all of which would rather forget I ever attended except when they want money.

Expertise

Telemedicine applications, embedded wireless machine-to-machine applications. Some user interface, HAM radio, CNC & 3d related (gcode! yegads! the worst language design of all time!)

Interests

CNC machining, thinking about making stuff.

Publications

Nothing memorable.

  • Product DEV-09627 | about a month ago

    I completely agree. I have purchased several of these, but it is impossible to understand the pin out without recourse to the Eagle files. At least I hope they will make things clearer. I don’t have Eagle installed so I haven’t had a chance to check.

    SparkFun should be ashamed about situations like this.

  • Product ROB-09347 | about a month ago

    Yes, I have the same experience. This definitely does not fit the ServoCity/Actobotics (now sold by SF, as well) ‘HiTec’ compatible accessories. Neither do some Spektrum servos I have.

    Are they ‘Futaba’ compatible? I don’t know…

    This arbitrary lack of compatibility between seemingly interchangeable devices is frustrating to me as someone not otherwise in RC planes, etc.

  • Product WRL-11129 | about a year ago

    I’ve been fiddling to make this capability for myself for a long time. Never got it finished, of course. I picture it attached to an app that would respond only to selected SAME region codes and pop up a web page that aggregates relevant information. Useful for Ham radio people and weather spotters and anyone interested in such things.

  • Product ROB-10332 | about 3 years ago

    I just received two of these along with two of the medium servos. Quite a nice claw for the price! But I’m not so sure the claw and the servo are such a match made in heaven. Though I can assemble things to generally resemble the stills and the video, everything seems twitchy at best.
    The servo does not really fit the existing hole in the assembly as I would expect it to. The long screws holding the servo in place are not quite straight, and it seems that a good bit of screw re-tightening would be required to keep everything working for very long.
    Perhaps someone with more experience using servos can say if this kind of spec mismatch is the norm, or just me worrying. This isn’t a criticism of the arm, it just doesn’t seem to be such a perfect fit to the servo as is indicated.

    What about the memristor, the properties of which depend on both current state and the history of the system? HP announced their implementation two years ago today.

  • Product PRT-08723 | about 5 years ago

    This board is great!
    It would be very useful, though, if the rows of PTH holes adjacent to the SMD pads (at least on one side) were connected. This would make interfacing to off board resources with standard pin headers or wire wrap much easier.

  • Product PRT-08620 | about 5 years ago

    This board is more useful than I thought at first. The positions of the pads are well selected for most SMT purposes.
    It would be very useful, though, if there were a row of PTH holes on one or both of the left & right edges, perhaps connected to the adjacent SMD pad. This would make interfacing to off board resources with standard pin headers or wire wrap much easier.

  • Tutorial - GPS Buying Guide | about 5 years ago

    What about PPS output? Which of these have good timing specs and easy access for use in timing and frequency control projects?
    The GPS/GLONASS and soon-to-be Galileo satellite constellations are basically a bunch of orbiting atomic clocks. Well designed receivers can be put to many interesting, truly geeky projects (see the http://www.febo.com, the timenuts mailing list at time-nuts@febo.com, and their ilk). With care these devices can provide time information down to the 20 nanosecond level.

  • Product LCD-08884 | about 5 years ago

    I have one of the earlier serial DX-160 serial 160 x 128 displays. How is this different?

  • Product DEV-08183 | about 7 years ago

    I like this thing. It is easy to use for quick tests & prototyping. The ‘basic’ environment supports most common chip to chip communication strategies directly with a minimum of code, and the CPU is fast enough to bit-bang most anything else. I never was much of a stamp fan, but this hits a critical mass of usefulness for me…
