ThunderBorg and MonsterBorg

Hi,

If I were to use two Thunderborgs, a Raspberry Pi, and a 14.8 V LiPo battery to power four 12 V DC motors, would it be possible to step down the 14.8 V output from the Thunderborg to 12 V to power the motors without the use of a buck converter. I've read that the Thunderborgs can be used to step down voltage but I'm not too sure how. Could someone point me in the right direction?

Thanks!

Can I connect a push and pull solenoid to a thunderborg?
Many Thanks

Hello,
How would I connect two thunderborgs and power them each separately?
Many thanks

Hi All,

I'm a lecturer at Newcastle University and I've got 10 MonsterBorgs and a group of undergraduate students working on various projects with them. I'd really like to access the racing code and simulator on SourceForge, but there doesn't seem to be the option to buy entry right now. Does anyone know another way to pay to access these resources?

Regards,
Ken.

When I power up my thunderborg with the lid (using a 12-volt aa battery holder) and connect it onto my pi, the light sequence works, however whenever I attempt to run the motor GUI, the raspberry pi crashes and everything reboots. Futhermore, when I try to run the motor or LED GUI, the thunderborg becomes unresponsive and nothing works. Could you please help me understand the problem? This has happened with two thunderborgs I have purchased.
Many thanks.

Hello,

in short I would like to know how linking 2 ThunderBorg Boards work, apart from giving my 4 motors their own driver(?) is it just a case of allowing separate power also? so I could have 10 aa batteries (advised) on each board? meaning 2 motors have 10 aa batteries each now? meaning twice the life so say? if this is true it leads me to the next part..

so I actually want to use 2 x 8 aa boxes per thunderborg @ 19.2v powering 2 x 12v 450rpm motors will this work ok ?

Hi guys

After using my Thunderborg motorcontroller for a couple of months, it has suddenly stopped working. During some tests, my hole system suddenly completely shut down. After some troubleshooting I discovered that it was the Thundeborg that took all the power. If I try to power the Thunderborg up as standalone, it just drains the power completely. When connecting the Thundeborg, my powersupply drops from 28 volts to approx. 0.7 volts. The LED does not turn on.

Do you have any suggestions?

Thanks in advance

Morten

Hello!

I've been using my ThunderBorg cards for some weeks now and there are some things that arent clear for me.

Hi, I wasn't sure if I was to contact you directly or use the forum, but the site states that support issues should be addressed here...

I've got a functioning Thunderborg in that I can run tbReadBatteryStatus.py, tbSequence.py and the motors run fine. I can clearly communicate over I2C to the board, and until today I had a functioning LED that reacted to the GUI and provided a clear battery status indicator. Everything seemed fine.

Hi,

I have 2 thunderborgs, that each power 2 windscreen wiper motors. Each thunderborg has it's own power source - a 12v mobility scooter battery each. So 4 motors powered by 2 thunderborgs. The TBs each have a unique address and are both recognised by the supplied demo code ok.

The problem is that all 4 motors stall immediately. But when I remove 1 TB, so I have have just 1 TB powering 2 motors, it works absolutely fine.

Is there something different I have to do with the wiring to enable each TB to be driven by it's own power source?

thanks
