Show and Tell / Re: High speed tracked vehicle....something different

Hi Luke,

Thanks for all the support.
I'm a bit of a noob to this all so I don't have the skills or knowledge to really dive into the Arduino proposal.

But one thing I thought of, when the avrdude gives the error that the target isn't responding. What is it referring to? The USBasp or the TCB?
Because the identical comes up with or without the crystal in place would lead me to think the problem is somewhere else?

Could be indeed a faulty USBasp, though the changing of the driver with Zadig work fine every time. :o

Hi Luke,

Got the crystals soldered on and was deeply hoping the board to light up, but it still gives the exact same message as before  :o.
Tried it again with different power sources, both USB and external 15V. Does the USBasp require anything else done in preparation other then the driver and jumper switch to 5V?
I have no other clue on what to try next  :-\

Hi Luke,

For what I was able to find so far, the crystals do not have any specific orientation due to polarity or ground etc, correct?
It can be randomly placed because it is mirrored right?

Thank you so much!!  8)

I'm going to have chat with the maker first!
Will revert once I have some crystals in place!

Hi Luke,

I now tried it with an external power supply, up to 15V, desperately expecting the TCB to light up like a christman tree, but no luck.
Figured there might be something wrong with the chip, so tried the second board, but the same message comes up with both boards.
Starting to look like something went wrong with fabrication perhaps?

Attached some pictures in case something might stick out ( I'm aware the radio connection isn't populated).
After a very close look, I did find 2 chip soldering connections that where connected with a tiny bit of solder, I cut it out with a hobby knife.

Is the FTDI friend a more secure way to flash the chip?

[EDIT]: Added the batch file as well, just in case.

Hi Luke,

I did try it once by moving the jumper on the USBasp to the 5V position, will try that again.

I powered the TCB through the USB connection as shown in the instructions, but should it get more power? I can try it with the USB cable hooked up to an adapter or powerbank instead?
Or should it be powered through the main power connector only or together with a USB cable?
Since the picture in the instructions only showed the USB cable I only tried that.

Thanks for your time!

Hi,

So I got myself an USBasp and 10 to 6 pin adapter https://nl.banggood.com/10-Pin-To-6-Pin-Adapter-Board-Connector-For-ISP-Interface-Converter-AVR-AVRISP-USBASP-STK500-Standard-p-1413166.html?cur_warehouse=CN, downloaded Zadig and changed the driver as per instruction, all fine so far.

Then, amended the batch file as instructed, verified the correct file paths and changed the programmer type to USBasp.
Made triple sure the 6-pin connector was in the right position by checking the ground position
Ran the file, and the attached file is the outcome. It says the target doesn't answer.

I then tried:
- Change USB ports, for programmer and USB cable
- Changed programmer driver
- Checked batch file a few times
- Restarted
- Checked dipswitch positions, tried both position on #5 just in case it had something to do with it.

 ??? Any suggestions?

Fantastic, and what a service, thanks! Have ordered it and will revert with an update once I've got the stuff in.

Hi Luke,

Glad that you asked, so far it isn't going too smooth.
Have done the USB driver set up according the Wiki, it is now shown as COM3 in the Device manager. Had to adjust the Baudrate to 115200 and did all the other setting according the Wiki.
Though even with the snoop and trying every USB port on my laptop, it doesn't want to connect.
In the device manager it says that the device is working correctly, but is does also give the message "Device FTDIBUS\VID_0403+PID_6001+AB0M9RB0A\0000 requires further installation".

I have tried installing the FTDI driver several times and re-starting etc, but so far I'm unable to get a response from the TCB unfortunately  :(

Should it make a difference if the TCB power switch is fighting or repairing?
The LED closest to the USB socket does light up when trying to connect, but that is about it.

Hi All,

So for the past few months I have been entertaining myself with with building a kind of tank-ish looking thing.
Wasn't too sure on what I wanted it to look like, but I wanted it to go fast.
So with 2 x 56112 780 kV motors on 8S, I should be in for some fun. The test runs on the stand where actually pretty scary.
It's 800 mm long and 450 mm wide, weighing in at a healthy 15 kg.

And today, after a bit of waiting, I finally got my 2 brand new OP TCB delivered  ;D
Took the gamble and had them made in China, so fingers crossed they're ok!
Will start digging further in to the startup and configuration as I want to drive it with a pistol grip radio.

Any good suggestions for a shell / body?

For some reasons the pictures don't show in the preview, let's hope they show in the post....
[EDIT]: yes they do :)

Great! Thanks, hope this can be sourced locally!

Hi Luke,

I took the plunge and I'm having 2 TCB's made in China, so far so good.
Only thing is that they seem to be unable to get a hold of 743C083151JP RES ARRAY 150 OHM 4 RES, the feedback is that it is discontinued.
As I'm far from an electronics engineer, what would be an acceptable / suitable replacement?

Printing is done and all other components are in, so they'll be assembling soon :)

Kind regards,
Chi-el

Hi guys,

Thanks! It is not part of the design at the moment, but there is room to put it in if needed.

It is mainly to ensure a better control when 18 kg is hurtling in the wrong direction at 100km/hr. The drive line is laid out for it though so will use that first.

Anyway, thanks for now. By the time it is up and running I'll simply test it by hooking  a servo up to the receiver and see what it does.

Kind regards,
Michiel

Or what if I stick two receivers in there, bind them both and one only connects to the TCB and the other one just feeds the braking servo? Or is this just too simple of an idea....

Hi,

Thanks, but I'm using a FlySky FS-GT5 with IA10B receiver, so not much to program there I guess.

Would the TCB be able to facilitate any form of controlled brake function?

Regards,
Michiel
