I got a pretty lamp frame from the dumpster few weeks ago, "the electronics" is burn by I like the frame design ... so yesterday I got few 4 leds square ($1.50each) and a switch from the surplus store nearby :o) I have few 12volt dc adapter laying around so I will reused one of them.
Tests, 2 squares will be enough, each square need 12v and 75mA.
so this week I will take some time to drill some holes, build some bracket, wire few things .... and maybe have a new dumpster lamp !!
[quote author="Graham242"]The USB serial for android lib claims it supports CDC/ACM, so it's worth a try using their example code and see what happens. I suspect you'll need to add the PID/VID you're using to UsbId.java and the definition into CdcAcmSerialDriver.java.[/quote]
Well in fact it does works at least for making connection tests :o) I had to add the PID/VID definitions in both UsbId.java, CdcAcmSerialDriver.java and also add permission filter in xml ...
So thumb up for that lib :o)
I might not used it tho, I might rewrite a part of that, in a real slim way in my application...
So ! .... 2 years later, here an update on living with my dangerous Flash Destroyer hack !!!
First off, front and back picture :o)
I added few things since its birth ...
A battery for the real time clock, really handy when you reprogram code and you don't want to lose the current time ... 4 buttons who are routed to the bottom left header, and who connect to the IO chip with green jumpers. Some kind of feet, printed on my Prusa2 clone :o)
So what is it life since 2 years ?? well this is my principal clock on my desk and I use it from time to time has a prototype board. So it turn out pretty handy and I still love the look, (and the weird look of people looking at it) :o)
I added software to helping me with things. There's 3 different kind of clocks, a standard clock, date display, another alternating hour - date clock, and clock with strange font...
After than I have menus to display the read out off the IO chip. and few entry points to custom piece of code I want to used or test, related to breadboard use or piece off code I want to try.
Ex. I used it to test a generic soft timer package, trigger at day-time like... I used the IO for triggering a 433mhz kind of beacon for a while ... and used input mode to validate a 4 lines status of a thing I built...
So everything was fine until just before last Xmas .... It suddently started to reset itself .... Geez I thought it was dying ! so I tested all chips , just to find the IO chip was going mad after few i2c messages , wierd... After swapping the chip, it was like new :o)
Since then I used it few days, for adapting the microchip USB stack, it took me a bit, cause MC, did not fully port their usb cdc exemples niether their stack to the xc8 compiler ... ( I cannot used the DP usb stack for the next project :o( )
So now it is working, the next step is to find an Android driver who emulated a serial port (usb CDC) and link my cheap android tablet to my cool hack !! Anyone have done that here ?
so what is the life of your dangerous things ! ? :o)
Since few months I basically used my BP for tests of some i2c chips. I loved it so much that I did patch the firmware to have it display read values in different formats ! Thanks to developers here this is now include in the last beta :-)
Yes it is right $25 for 1 DLatch ! They are cool tho they added more shipping services to Canada, now the lowest is only $28, when I checked they had only express shipping for $115. Yes I sent them a message, and YES it is for 1 ic only !!!
Another ebay seller sold me few for 0.25 each with free shipping...
Since that time I'm thinking to open a store and sell all my old ( but not used) "ls" family ic stock, at only $20 each !!!
I set a max bid of either $0.99 or $1.26 depending on the item on about 300 auctions over the course of a few days and in about 25 of them I was the winner.
Amazing! And the trickle of random stuff will be a treat for weeks to come![/quote]
It feels like it is Xmas everyday for me, I ordered a bunch of stuff too from ebay, but you never know what you will find in your mailbox !
Last week I got jumpers !!! [attachment=0]
I had a small bag with few tens of them always handy when you play with computer parts ... but misplaced it during xmas time ... I went to my local pc parts place ... they sell them something like $1 for 10 jumpers !!! WTF ! So I ordered a BAG of them a 1000 jumpers ! for $8 , I will have jumpers for the rest of my life for sure ! :oP
Nope windoze fall apart alot faster than any hardware will drift ! One of Windoze greatest achievement is its super marketing product life cycle !
endless 2 years cycle market strategy buy the new Windoze ( so better than the old one, with NO bugs), give Bill few $100 add patches over the first year crash so often for the rest of life than you need to reinstall all stuff time to trash it for good , restart the cycle :-/
This life cycle is so well accepted than alot of products are now made to break after 2 or 3 years !
It wasn't like that long time ago ... I have few old 30 years old computer still running fine ! :-/
