you might be able to make some money from these guys : www.playdust.co.uk .. they would prolly need a bunch of em
Well we now have a great count down timer thanks to acrimonious. But a blinking LED, and buzzer can be inserted direclty to the 555, and create an additional effect.
You guys seen "Executive Decision" where they're playing around with a bomb and someone remotely initiates a check procedure and there's a bank of about 10 relays clicking randomly as they check, I always thought that was cool and it scared the poop out the disarmers..... Maybe an Idea for a future revision Oujia, you started on any of the construction yet?
Hm, wasn't that "Critical Decision"? Anyway, that was a very cool scene . The bomb specialist had a broken back right? And it was in a plane?
definately "Executive Decision" I've got the DVD, and the namesake line of the film... "This is now an Executive Decision"
No, I haven't started construction yet. I'm using a small maplin aluminium box, but I haven't got any of the components yet as I'm broke from buying my airsoft rifle Also need a new camera next month, but that's another story Damn Finepix 2300 not recognising smartmedia cards
I've brought myself a copy of PCB Wizard 3.0 (great little program), but I'm having trouble creating a 9V / 5V / 0V rail lines. I'm sort of new to the PCB wizard program, but have created The countdown module circuit using acriminous's Livewire picture posted previously. The Current circuit is as below The other modules will be wired in seperately using the IC4 & IC6 connectors. I've uploaded the bombdisplay2.pcb file from pcb wizard 3.0, but would apreciate it if someone could create the PCB track layout. I've tried the autorouting, bt it just seems to be a jumbled mess. Download the bombdisplay2.pcb file here
If you connect all the like rails to one rail. So all 9v to ONE 9v rail all the 5 to ONE 5v rail and so on you will get a much better PCB. EDIT, give me a few moments and i'll upload another livewire file.
Its a shame but auto-routing is really no subsitute for manually routing out the nets. Import this file then select and auto-route each 'module' INDIVIDUALLY then when you have all the midules done (6 boards) copy and paste them all into one file and join them up with the wire tool (the blue strand). PS, having troube with my webserver, if the file doesn't work try it again in about 10mins
Acriminous. I've been trying to download the file for the last 2 hours, but no luck. The rest of your website is ok. Let me know if/when it's working again. Cheers! BTW I've taken your advice and split each display into modules. Also a quick question. The terminal next to switch2 on your original / and my copy diagram is a 0v rail isn't it?
The file is ready for download now, sorry about that, i had to re-upload it. On this diagram, the terminal connects to the other terminal with the same label (its at the far right in the box). Same goes for the one labeled 555 POWER. It would be better if you used the circuit i've just uploaded, it has a few additions and is the final design.
just one other question. if you have a 9V rail and a 5v rail, what's the best way to step down the voltage for the 5v from the 9v?? (I'm planning on using a 9v Battery for power). (believe it or not I did 3 years at college studying electronics & computing, but that was a while ago. I've forgotten almost everything since then)! If i can get the transparency print out to a high quality image, then I may be able to start the PCB fairly soon. Else I may be asking for a quote for the PCB design & production! Cheers once again.
A voltage regulator is going to be the best option. Perhpas this cirucit will help you figure one out: http://bit-tech.net/article/52/5 That goes from 4v-12v.
you might want to take the housing into consideration when making the PCB design, for example, putting this into a 4" diameter pipe woudl be pretty cool. then grab a cheap plastic "project box from radio shack. cut indentations on either sides. so it rests flush to the round-ness of the pipe. then put all the "Defusing" stuff in there....
Cheers Acriminous. I'll see what i can come up with Good luck with it. hope we can both try to keep this updated! I think that's going to be quite a tight squeeze. I'm planning to use an ammo box, like the one below. http://www.allthingsmilitary.co.uk/ishop/images/800/ammo_boxs.jpg Changed image to a link, if you are not hosting it please just use a URL link -ZapWizard fair enough! - I have now added the jpg to my host - craigey1
guys, just checking....... The Voltage regulator below should work , shouldn't it? L78S05CV (has an output of +5v and an input of +8V to 35V)
