Zaurus - Basic Stamp Relay Controller

I've created a small platform consisting of my Sharp Zaurus SL-5500 interfaced to a Parallax Basic Stamp 2, which I hope to detail soon in further videos/pages.

Let me know what you think!

In this instance, I have the Stamp controlling a D latch assembled from a 7400 and 7404. Q goes to an NPN transistor which powers on a relay when the latch is set High. The relay in question interrupts the power going to a power strip I've modified. To this I have connected my desk lamps, which I'll dazzlingly wink during this stunning presentation

The Zaurus runs OpenZaurus 3.4.1 with GPE; I ssh to it through my desktop, then run microcom to open an interactive serial session. My entire setup is linux (my 2 desktops and laptop run gentoo), so this is extremely flexible.

Until I make a page for the platform proper, some other info:

I built assembled the platform several months ago and had apache with php running on the Zaurus; a simple web interface would accept GET requests and run appropriate shell commands, like "echo T > /dev/bstamp". It's that simple!

I tried (again!) to get kernel 2.6 on the thing via several methods, and have yet to reinstall apache :-) So web interface coming again soon.

The Zaurus is an ARM processor. My original goal was to have my entire Basic Stamp development environment on the Zaurus, however Parallax has only released an x86 tokenizer: I can download tokenized programs onto the Stamp and communicate/interact with the Stamp, but I must use a desktop to tokenize until there's a way of tokenizing that doesn't rely on Parallax's x86 tokenize library.

Questions, help, or maybe you're scheming like me? Let's build shit!!

Congratulations! Remotely-controlled finite state machine controlling a lightbulb switch...for the win! And glad to see you use linux!

@ericfontainejazz Years ago I designed a relay-CPU that used an extended set of brainfuck with paging to access hardware. Haven't built it yet :-)

Been exclusively Linux for nearly 5 years :-) Gentoo fellow myself, I remember trying LFS when it first came out.

Damn man we should have a jam! :-)

[SIMPLEPLANROCKS22]

how do you build a relay controller

[herzogsbuick]

@SIMPLEPLANROCKS22 for what?

[TheRobynhud]

you shouldbe getting placement advertising for TUMS,other than that i dnt have any idea what this vids about but nice to catch up on what you are doing;)be well

[dragonny4master]

Looks very interesting :)

[ellpancha]

i knew that, was a joke

[herzogsbuick]

in english, fuck ya is fuck yes, NOT fuck you :-)

[ellpancha]

fuck you jeje

i have an other cuestion, can i conect 12v directly to the bs2 pin as an input, usin just a resistor? or conect a transistor as an input?
