Open Panzer Help / Re: Compatible teensy versions
« on: July 11, 2022, 09:55:01 PM »
Thanks for the tip Luke, just wish I'd checked sooner......I've got three 4.0 teenie's now that are no good to me...no wonder my sound cards wouldn't work!!  I think they loaded okay, just seemed to act a little wierd.  Now to find some 3.2 versions...maybe I'll get lucky :)

Hi Luke,

So I just uninstalled 0.93.74 and reinstalled 0.93.73 as per your instructions (being careful to actually READ them .... lol), and all seems to be okay.  I downloaded the latest and installed it on a spare OPTCB and even installed some settings on it....so you fixed it, whew!!  So glad my new laptop is working with your wonderful program....

Thanks again!!  Jerry

Hi again Luke,

So I did the download the executable , and it simply downloaded the old one apparently as the results were the same (as I noted above).  So I did the check for updates next, and it downloaded the new version.  Unfortunately now, when I select the 'get the latest', the OP program goes to the blue donut of 'thinking', and no longer responds, I have to go the the task manager to stop it.   

I'd like to give you a screen capture, but am unsure of the keystrokes as I don't do that often......

Hmmmm.......

Hi Luke, 

Boy, that was quick. 

Sorry to report that it is still selecting the 1kb size hex file, and it is still numbered oddly.  I also get a script on the screen saying:

Moved Permanently
The document has moved here.


and under the file name is:

Version: <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//

if that helps?

Thanks for the continued support!!!

Hi Luke,

Happy holidays to you and yours!!

So I just got a new laptop from Dell, with windows 11 on it and I'm having some issues with OP Config.  When I select 'Get Latest Release' I get a different hex file name each time, like TCBMK1_99-61-99.hex which is only 1kb in size.  The names vary in the numbers only, and of course, they won't flash since they apparently have little to no content. But if I select 'use your own hex', I can see the older versions and they will flash.  Also, I can download the latest hex manually and it will flash. 

Another oddity is that in the file manager, if I try to see what is in the folder where the hex files exist, they won't show unless I have manually downloaded it, but OP will show all that are there....

I guess windows 11 is a little different?? 

Anyways I got it working okay, but just wondering what is going on. 

Thanks,

Jerry

Isn't that an old Taigen/HL recoil unit, not an airsoft?  Are you saying they are wired the same? Makes sense though, just a motor moving until switch opens/closes....

Before you ask, here is one for the OPTCB.....

Hi all,

Thought I'd share the cradle for the FatFingers DIY board.

Hi Luke,

2.1 amps....back in 18......must have been an abused smoker  8)

I seem to have melted a few down too..... :-\

So I pulled out two new, one used Taigen V2 smokers out of the spares bin and messed around for a little while. 

I hooked up my FatFingersV2 board, and put the Fluke in series measuring amps in the AVG (average) mode.  At 80 percent setting at idle, I got 0.56 to 0.60 amps on all three smokers.  It goes up a bit when increasing the throttle to 100% as set up on the board, but not much.

So I then plugged the smokers directly into the battery at 7.89volts unloaded 6 cell NiMh.  This yielded 0.73 to 0.80 amps.   

A curious thing is happening though when you let the smoker run for a while.... The current reading, starting at 0.6 amps, would slowly rise.   At roughly the 2 minute mark, the amps had increased a little over 10%.  The front of the smoker got hot, could hardly touch it....I wonder if my previous readings were maximums with a very warm smoker?  Perhaps.....

So the resistor in the stock Taigen V2 units is a NiCr wire, wrapped around a fiberglass or silicone fabric cylinder, right?  Small, but effective..  I've seen them, after much use, turn all black, burnt to a crisp.  I wonder if the heating action eventually turns the insulator to carbon, reducing the resistance causing even more current to flow?  Right now, I've given up on the smokers, just replace them as they fail since they are cheap.   HL now has a newer version though, that has an improved resistor configuration (V6.0 I think) which has the wire wrapped piece inside an insulating tube, which wicks up the fluid.  The resistor is smaller than the Taigen version, and instead of a wad of cotton to wick the fluid up, they use a little sponge.  I have one in my JS2, and so far it hasn't failed me.  I haven't done a current read on it yet, but the resistance is in the same ballpark as the Taigen IIRC.

Thanks for doing the current calcs, at least it looks like the board will survive a stock smoker.  No temperature rise on the traces was detectable after the 2 minute run above.

Hi Luke,

Thank you so much for the kind words, especially since mine is obviously an amateur effort.  One doesn't appreciate what effort goes into a boards design until one attempts his own!!  Your layout is really a piece of art!!  I can't imagine how long it must have taken to get all those bits and pieces to align and fit on a 2 layer board, it boggles the mind.

The Arduino I've located to replace the Robotdyn that works is from ebay: https://www.ebay.com/itm/274262551130.  I have two operating, so far so good.  I hope Robotdyn has fixed the 5v regulator issue, as I fear the ebay source will eventually dry up/change.... I will try again at Robotdyn, in the near future.  I could not find another 'commercial' outlet for the board, that would be a better source?

I think the OSH boards are better quality than the Seed version.  I was replacing that pesky transistor Q7, and the pads wanted to distort/lift on me with the Seed PCB.  The OSH pads seem to be better anchored to the substrate.  The reason I got the thinner board from OSH is that they don't offer the 1.6mm board and 2 oz. copper.  I have a good friend who I went to school with that went into the electronics field, and he recommended I use 2oz copper.  I'm not sure how 1 oz would work?  I really didn't do any current calcs on the board, simply went with as large a trace that would fit in the confines for other than signals (smoker, airsoft, etc.).   Also, the purple is a nice relief from the standard green color  8)

I feel honored that I'm the first on the Members Design!!! thank you.....Jerry

Hi Luke,

Well I think I'm done with my shield.  I called it 'FatFingers' since us old folks can't seem to manipulate the SMD components too easily. 

I've included the Gerber zip file, and in the Here is the FatFingers V2 boards zip is the PDF of the schematic, the BOM in excel, an assembly writeup in Word, and the Eagle files.

I hope this helps someone who wants a TCB but can't manage the SMD and flow soldering.  Let me know if you have any comments?  I've assembled 4 of these so far, with 6 more to go.  Takes me about 3-4 hours for one, but doing multiple takes less time per board.

Thank you Luke, especially for the advice on the bias resistor. 

I hope to finalize everything soon if this works, all else seems okay.   I plan to share the eagle/gerber files along with BOM and details on assembly.  It should be a much easier build than the original, but same footprint and connectors though without some of the frills which I have never used in any of my 12 tanks that have OPTCBs.....

Anyway, hopefully it will help your awesome design continue on.  I cannot thank you enough.   :)

Hi Luke,

I just ordered these up to test...should work?  I hope not to have to modify the boards/submit a new board request since it took 3 months last time from Seed  :'(

Hi Luke,

I'm just about finished with my shield, but am having difficulty with the airsoft.  I measured 1.7 amp max on my DVM for the airsoft unit, and I don't think the BC337 is up to the task since it won't even start the motor running.  BC337 is rated at only 0.8 amps, and the surge must be too much on motor start.

Would you have a recommended TO92 replacement in mind?

Thanks Rich,

I'd not heard of conductive adhesive.....sounds interesting....as long as its long lived? 

I finally found a socket that had pins accessible by a soldering iron....tiny indeed!! 

Now if Seed would finally get my first run PCB's to me....the Corona seems to have way laid them ;)  and OSH seems to have raised their prices by 1/3....sheese.
