Dome electrics - power connection

As I'm still waiting for parts, I didnt want to be left waiting to be able to power the dome motor. So I rigged up a stand alone unit, with voltage step down power.

Dome power & switches - R5D4
The two micro-swtiches mounted with the micro servo.
Digital Volt meter with Voltage Regulator below it.

The unit takes its power from a split connection plug straight off the 24 volt line. This feeds into the voltage step down unit and is monitored by a digital volt meter. This then feeds the dome motor.

There was an issue with the servo not working(?) The transmitter was working, but the servo only twitched when activated??

.......ordered another servo......fingers crossed!

R5-D4's Sound system installation

Started work on drilling holes and positioning components. I sort of know where everything should go, but am still waiting for the 12 channel remote, to be able to finally know what space I need.

I'd ordered some PCB nylon spacers 12mm long, but these were too long for the 20mm bolts and ny-lock nuts, to go through the Amp's holes and the Perspex board. So had to cut the spacers in half. Not the end of the world as means I've got twice as many now lol.

Marked and drilled holes for the four bolts & one hole for the power cable to come through.
This was as far as I got. I had to re-solder the fly leads on the original digital volt meter as they had broken off through use. I then applied hot glue on all three digital meter's contacts, to prevent strain on them.

My speakers came, and it's been sooooo long since I've bought car speakers, I forgot they often come with speaker wire too lol, bonus. These are Pyramid 3.5", 8cm, 240w Coaxial Two Way's.

I plan to have them mounted onto the main electrical board via a second stand off board.
First, I marked out some perspex and drilled/bored out holes with my adjustable cutter. Machined up some aluminium spacers for the screw positions.
PIC of perspex with speakers fitted - still W.I.P.

The board still needs to be to size suitable and fixing holes drilled for it to be attached to the main board.


R5's smoke system - 1.5 - Video Dome Test No2

Although I was happy with the 3volt pump I used originally, I wanted to know if there was something that would move the vapour smoke a bit quicker. So a quick search on eBay and I found this 6volt pump. Wired it up and it works great! Click on You Tube link to view.

I first wired up the pump in 'parallel' with the e-Cig [both running off a 6 volt battery] but it was too powerful for the vapour. So I tried it in 'series' which reduced it's power, but still did a great job of moving the vapour out of the e-Cig.


R5's Sound & Electronics Board

Only been able to do little bits here and there as components arrive and I can then assemble them.

My 2.5mm centre positive, £1 off eBay jack plug arrived the weekend, so was able to Solder up the power wires to it, but the cover wouldn't fit over the cable sleeve, so I didn't fit it and used heat shrink tube.
Sure Amp - jack plug

Also the 6volt air pump arrived so I could see how it performed compared to the 3volt one.

I first wired it up in 'parallel' but it was to powerful for the vapour, so wired it in 'series' which reduced it's power, but still did a great job of moving the vapour out of the e-Cig.


R5's sound system & electrics - more components....

RCA lead and speaker cable have arrived.
Both will be used to connect up the Audio FX unit to the amp (RCA to single stereo jack plug) and the speaker cable to link to the trigger pins out to the 12 channel remote unit.

Cut a few lengths of speaker cable, trimmed and tinned the ends.
These are short in length to connect to one side of 12 channel remote.
The others I will wait till the remote arrives and can properly judge lengths needed.
Started to solder on the leads

Replacement voltage units came to.
Two hours of soldering, testing, unsoldering, re-soldering.
One blown board (so much for circuit protection & re-set??]
Two good ones wired up though, one now set to 6 volts.

Wednesday 4th March - My Sure Amp arrived

If I can sort out some speakers, get them fitted and the rest of the new electronics/electrics, R5 should have some sounds in him this month!!

Just the slip ring to arrive for me to then sort out R5's dome power.


Dome electrics - Step down power supply

Step down voltage reducer came in post yesterday.
Hooked it up to 7.2v power pack and digital volt meter and adjusted it down to 3.5volts.
It does say it's range is 3-40v, but it only showed min of 3.5v before the digital readout would go blank. Still 3.5v is still OK for running the smoke pump.


Next, was to test it on the pump unit. But after an slight incident(??) with the battery contacts, the unit's light failed to re-light and no power at end terminals. At £2.69 it's not the end of the world and have ordered some more. Still a bit disappointed with myself though.


R5D4's sound system 1.1 - Audio FX Sound Board

Have ordered more components for R5's sound system.

The 'Sound Board' I've ordered is an alternative to the normal one used by most builders. But at half the price, and after I'd checked with our IT guru's on the UK R2 Builders Forum, I was assured it will do the same job.

It's not MP3:
  Quote: The sound board is designed to be simple: it does not have polyphonic ability, can't play MP3's (MP3 is patented and costs $ to license, so this board uses the similar but not-patented OGG format, there's tons of free converters that will turn an MP3 into OGG), isn't reprogrammable or scriptable, and you can't have any other kind of trigger type. However, there's a good chance the project you want to make will work great.

Also bought some speaker cable, for the speakers (still to buy) but also for connecting up the sound card to the 12 Channel remote unit, which I had ordered, but then received an e-mail stating there were quality issues with the units so a refund was on it's way....
