What's Your Pi Plan??

Former Member
Former Member over 13 years ago

Hi!

 

Just curious about what people were planning on using their Raspberry Pi's for once they started getting them!??

 

Current plan- SFF Media PC / NAS etc mounted onto the VESA on the back of my TV

 

Later plan- Replace car stereo etc with RPi

 

Probably not the most origional use there but still, godda start somewhere!

    I have at least sort of two different plans with the Raspberry Pi

     

    1- Use it for research on low cost embedded Linux application development as a remote or central controller for other systems, Internet of Things kind of stuff

        Some of the stuff I'm working on I started to post it here http://www.element14.com/community/thread/18981?tstart=0

     

    2- I was planning to put together sort of a development lab, contributing my time and funding to have a bunch of R-pis on a local High School, but I'm having second thougths about it given that I'm loosing confidence in the Raspberry Pi Foundation to be able to deliver, and some attitudes that have been developing over there, on top of some of the techincal issues related to the board. I'll probably put the money on something more reliable and with more features, it will probably be more expensive but at least it won't blow up TVs or force me to try a collection of power supplies, SD cards, keyboards, etc, etc, to make sure they work

     

    I was really excited about the R-pi, I've other ARM based development boards such as Beagleboard, Beaglebone, Pandaboard, etc., but my level of exciment with the Pi declined considerably, I'm now waiting for shipment of the http://apc.io/.

    The apc looked interesting, sensible size, mounting holes in the corners but the 720p & no general purpose i/o is a downer.

    It's a gathering of old-timers here.  You too probably remember reading code by holding up paper tape to the light. image

     

    The Pi founders talk about the BBC Micro like it were the dawn of computing, but really they were 2nd or 3rd generation, just users of consumer gadgets with all the rough edges smoothed off for public consumption.  The hardcore technical work came before that.

     

    Programming in Python won't really tell youngsters much about their machinery, although hopefully it will get them interested in technology in general, so it could be a stepping stone away from consumerism and towards better understanding.  I hope so.

    Haha, nice.  I guess I'm a newbie compared to that, but I did possess a 64 KB hard drive (yes, Kilo) ex PDP-7, and I still have a pile of those old DECtape cases which I use for component storage.  Oh and I preserved a 2MB RK07 removeable disk pack for posterity, just because it was reputed to be the base model for Hans Solo's Millennium Falcon. image

     

    From a slightly more modern vintage, one of my main racks here is from a PDP-11/34.  I'm so sad that I didn't grab the old PDP-11/20's binary toggle switches when the machine was thrown away, on which I'd entered the bootstrap code from memory so many hundreds or thousands of times.  I'm not really much into memorabilia that isn't functional, but the switch panel could have been interfaced nicely to an ARM Cortex to make a pretty unique UI for binary-aware techies. image

    When I moved from New Jersey (where I had a basement) to Texas, I had to leave behind a lot of equipment. I worked for several years with the company that ran one of the original NSFNet regional networks, JVNCNet that was build around the Princeton University and the John Von Neumann supercomputer center, after the center closed we inhireted a lot of stuff.

     

    Some PDP-11 19" racks ended in my basement to mount part of the equipment I used for R&D in large scale networking and other stuff, in front of the racks shown in the picture I had a running PDP-11 and a Microvax, can't find where I put a picture of that one.

    @jamodio: Yup, same rack system, except that mine has an ornamental head section and I still have the slot-in side covers on mine which you've removed there.  Awesomely strong hardware, built to last forever unlike some modern racks.

     

    I was so sad when DEC were purchased by Compaq, a mere PC company.  I knew it was the beginning of the end for their professional quality hardware. image

    You bet Morgaine, I also miss DEC a lot, and the old Hewlett Packard too, I remember anxiously waiting for the latest catalog or HP Journal to arrive on the mail, now not even Circuit Cellar is worth the money.

     

    Some of the things I still have with me, is a collection of HP Series 80 desktop computers, once in a while I still use them to control via HP-IB a bank of instruments.

     

    Here are some pics about how my office/lab looks like:

    Sorry Folks for the totally OT thread :-), but kind of interesting to exchange some of this stuff.

     

    Cheers

    We mostly had pink paper tape, so you didn't need to hold it up to the light like black paper tape.  Yellow paper tape had an icky color IMO.

     

    For one class, we had limited access to a shared PDP-11/20, so I entered the first draft of my PDP-11 ASM programs using an off-line ASR-38 teletype, punching the program directly onto paper tape.  You had to type carefully because it had limited back-space capability.  If you made a mistake, you pushed the punch's backspace button one or more times and then typed one or more DEL characters, which as you all know from the ASCII chart is all ones.  This told the paper tape reader to ignore the deleted characters.  Then I transferred my program on DECtape and fixed the remainng typos and made other modifications with a text editor.

     

    Everybody else in the class used punched cards.  However, the card reader was flaky, so when it was down I got extra access to the PDP-11 :-)  Using the ASR-38 allowed me write lower case comments.  This was considered heresy and made me an outcast among outcasts :-)

    We had a hardware tech who liked to play a little joke after fixing the front panel, e.g., replacing one of the many incandescent light bulbs that displayed address and data.  He would run a program which executed code at clever addresses so it looked like the address lights were counting in binary, but bit reversed.  Then he's say "oops, I must have hooked up the address lights backwards" :-)

     

    I never had to enter PDP-11 bootstrap code -- we must have had the ROM option.  OTOH, I remember toggling in the PDP-8 RIM loader, which then read in the BIN loader, which then read in the actual program.

    Pink paper tape, oh my.:image  Never seen that before, ours was drab white, or slightly off-white.

     

    I wonder how we'd have reacted back then to someone telling us we'd be using terabyte drives and 4GHz processors by 2010.  And 32-bit microcontrollers for 50p in a washing machine ... although we'd have to explain "microcontroller" first. image

    I'm absolutelly amazed about how electronics have advanced since the day I met my first transistor.

     

    About the issue witth lack of interest in computer science careers, as I said before, it is not a hardware problem, so whatever the RPF intends to do to help goes well beyond a credit card size board with few chips.

     

    I believe that one of the problems, given how software development has evolved, young programmers today got used to just glue APIs together, the "black magic" of trying to fit a particular set of algorithms in 2KB of ROM got lost in the bloated amount of resources contemporary hardware provides.

     

    How the RPF plans to tackle it ?, hard to tell, as it was with the schematics for the R-Pi, information is sketchy and probably not open for discussion or contributions.

    They're doing an excellent job of educating young engineers for a job in China, or anywhere else where it is dangerous to question authority.

    I totally agree with that.  Adequately inexpensive hardware to do almost anything useful has been around for quite a while now.  I see the primary problem as missing documentation, which I refer to as "Doc-less SoCs" (yes, I had small children and read them lots of Dr. Seuss.)  It creates no end of frustration, and it's impossible to tell how many interested students are discouraged from going further.  A close second is the USA-driven software patent nightmare.  Many see no point in developing anything because if it ever shows signs of success sharks will appear and tear one apart.  The third is software bloat, but that's solvable so that's why I'm working on it.

    yes, in those days these computers that has ferite core memories there was no reset or reboot button. Even if you pulled the plug the computer stops and when you applied power back to it.... well it resumed exactly where it left off.

     

    so if your program was suicidal or wrote over itself you had to rekey it entirely, one word at a time with the switches image .

    after 2 or 3 tries, then one's tend to debug his/her program.

    No doubt having more resources is welcomed and a great advance, but those resources have to be used in a way that you can strike a balance on making software better more than making it easier to write. IMHO that's one of the problems I still see on Microsoft (and I've been couple of times at Redmond on executive meetings), and it makes Apple different and more effective, even when Microsoft has the brain and financial power to make amazing things.

     

    In many cases everything gets resumed in one problem, lack of leadership, I smell a lot of it at RPF.

    Oh, there's plenty of leadership at all the organizations mentioned.  The problem is which way the leadership is heading.  I once read an excerpt from an uncomplimentary letter of reference performance review: "His staff would follow him anywhere, but only out of Morbid Curiosity."
