I speedy, i have a problem ....whatch my tread here viewtopic.php?f=37&t=273&start=80 tks

Hi thecure :
Surely you have many disconnected track ... I suggest to put tin on all these weak tracks to see where the cuts are ? ...
Next time please ... upload pictures into this site as the other site is reported to my firewall as harmful and blocked ... I didn't see the details of your DIY board ...!!!

So I connected the cables (see photo) .. right? .... Before connecting the motor, I connected the tester, but does not seem to (see video)

Then I connected the motor but does this ... see the video P.S: but in theory it should turn on an LED for each direction?

Hi thecure :
Good job ... please give me a pictures of the top board with MOSFET's .

- about the direction led ... I guess one of them is reverse installed ...
- about the noisy operation try to replace the feedback pot ... it seems that it has a defective aria ... makes the motor stops and doesn't have a direction to go to .

[thecure]

for the led i have wrong solder (now are fine) ....... I changed the potentiometer but I get the same error

Hi Thanos ....
Congrats for your new home ...
Congrats every one from UK for that magnificent Olympic opening ceremony .Awesome and it can't be more beautiful
How is that big long Chimneys came out of the stadium earth ?????

BTW ...Thanos :this is really small dimensions you want for high Amps DIY motor controller ...
If you're really talking a bout a "5mmx5mm" even if you're talking about "50mmx50mm" ...
my board is 9.5x10 cm ... for one 50A DC motor ... higher rating is bigger ... but I've got your point .

The HIP4081AIPZ driver chip is a peace of art for technology lovers and a peace of luxury not every one can have it ...

forgive those people like me how can't have a double layer boards or a nearby board etching service .
I'm simply can't buy anything from eBay .It will cost me more than making it like a dinosaur .
There are some people that are beyond last week "Discovery channel ".

I feel the same here in Turkey, we are almost on the same bot, thank you for your great efforts

speedy, seems great work,

I will study your post (at least 3 more) to consider to make my selves, I am absolutely a beginner and like to do DIY bases, can I count on your help??

Hi Vicpopo

As Speedy doesnt seem to be about

Is your H bridge still working and would you recommend the build, looking for a high current board to run 24v 650watt motors with an Arduino

Hi Telfel,

It doesn't work but that comes not from the conception , I burned it with bigworm motor (12 V , 190 Watt) and amc1.6.In fact these motors has got a very low impedance, I measured 0,7 Ohm.
The first positioning at starting ( starting xsim) the amc ask full power. That means the h-bridge starts on the short circuit.
I burned several h-bridges and this one also.

But Speedy said and I agree with , that this h-bridge can handle very powerfull motors.I didn't test it with 24 volts.

The h-bridge is not easy to solder .Before taking your decison look at Pololu drivers also.You can contact Prilad he could maybe try to contact Speedy for you.

Best Regards
