call for help to the 'electronics' on this board for a Wirbelwind project
Hi chaps, i need help from the ‘electronically’ talented people in this board<o
></o>
I’m immersed in a new project, a Wirbelwind based in an old HL PzIV chassis. I want to hold the costs to a minimum, and I would like to use the HL electronics, the HL remote and a beier sound card for the sounds. I already own them, so I do not have to expend money in this area. <o></o>
The alternative could be the future Taipan board, or the RC2HL solution, but the shipping costs from OZ to Spain are ‘devastating’…<o></o>
Without taking into account the use of recoiling, if possible at all, I would like to know what you think about my idea, if it’s feasible or do you have any other way to do it… so:<o></o>
- imagine a turret less HL PzIV, with the Wirbelwind one installed and with the flakvierling inside<o></o>
- imagine that no servos would be used for elevation of the guns or rotating the turret, only engines.<o></o>
- the turret rotation would be the same as any other HL<o></o>
<o></o>
The standard HL ‘8 wires’ group of cables going from the RX18 to the upper hull is distributed in this way:<o></o>
<o></o>
pin 1 (black)-negative turret rotation (3.8V - 4.0V)
pin 2 (red)+positive turret rotation
pin 3 (blue)-negative motor gun fire recoil airsoft (4V)
pin 4 (yellow)-negative motor gun elevation (7.2V)
pin 5 (brown)+positive common to elevation and gun engines
pin 6 (green)+positive common to light and MG shooting
pin 7 (white) - negative light
pin 8 (orange)-negative MG shooting<o></o>
<o></o>
so then:<o></o>
<o></o>
- there would be no tank gun or recoil or fire system, then the pin 3 (blue) would be free<o></o>
- it would be possible to use the pins 6 and 8 for MG shooting to fire the flakvierling LEDs with the K button<o></o>
- on the remote, stick down controls the tank gun elevation, but on a cyclic way, the engine always runs in the same direction (no polarity reverse)<o></o>
- on the remote, stick up controls the tank gun firing<o></o>
<o></o>
Well, have I said any incorrect?<o></o>
<o></o>
Now, the possible solution to have elevation and depression of the flakvierling , up or down, without the cyclic thing, and is here where I need your thoughts and advice!<o></o>
<o></o>
Could be possible, to use the ‘liberated’ pin 3 (blue) (remember, no tank gun to be fired) to make the elevation engine to turn in the opposite way? <o></o>
With some electronic component? A polarity inverter? A relay? An H bridge?...?<o></o>
<o></o>
If this i just said could be doable, then the guns could be fired with the remote’s K button, the remote’s sticks down and up to control the flak elevation…<o></o>
<o></o>
What do you think? Do you have any other idea to achieve what I want?<o></o>
<o></o>
Best regards and thank you very much!<o></o>
<o></o>

RE: call for help to the 'electronics' on this board for a Wirbelwind project
thanks for your comments
Dan, the main problem is that i would try to use what i already have. Buying a DBC3 also requires a benedini, a receiver (maybe ESCs too) and a decent remote, same case if i buy the RC2HL or the Taipan (when available). One will trevel from north america, the other from oz ...
is possible that have to fall in changing my mind and be force to go one way or the other, but firts i would like to be sure that what i've thought is doable, or not...
looking for threads talking about electronics, servos, and the like, i saw replies from different memebers who have-it seems to me- a high level in this matter, and here is may hope, that any of them could say something...
Karel, do you have any link to your project? i would like to follow the work of others walking my same path!
best regards

the link is here so far : on BTB :forum.battletanksbelgie.be/viewtopic.php
i let you know when it starts

RE: call for help to the 'electronics' on this board for a Wirbelwind project
have i translated it corretly your link?? are you saying there that you will use a RX18 + DBC3 + benedini? also, i think that the soundfiles are a special mod by YHR and are already done?
i'm openminded, and i want to know what alternatives could be used in this project!
i would like to be able to customize the sounds, it's a feature i love in the Beier cards. Dan, could you explain to an electro-illiterate like me what could be done with your combo in order to run a wirbelwind?
the project i'm working on will use 3 servos, one for rotation, one for elevation and the other for the gun's recoil (yes, i've a colleague in a spanish forum who is SURE it could be done!)
if this is a viable option, then we could talk ;-)
any idea would be wellcome!
best regards

thanks for your reply
so, the Santa list could be:
- RX18 (i have it already)
- HL turret turn device (i have it already)
- DBCx (x=3?)
- benedini TS mini
- TBS programming cable
- 6ch receiver (wich one?)
- 6ch remote(wich one?)
- 2 mini/micro servos
- anything else?
the benedini, will produce ALL the sounds, am i right?
how would this combo manage to fire the 4 guns? using the MG instead of the main gun?
best regards
