Re: PowerBlock: A Power Switch for the Raspberry Pi

Jeff Williams — Sun, 06 May 2018 09:37:26 -0000

Do you happen to have a 3D Model (obj, stl?) of the PowerBlock? I'd like to be able to use it to mock up my case in tinkercad.

Re: Update for the ControlBlock Driver with Many New Features

petRockBlog — Sun, 29 Apr 2018 01:47:17 -0000

For now, ControlBlocks version 1.X need to use the driver at https://github.com/petrockb.... The instructions at https://github.com/petrockb... should work.

ControlBlock ver 1.6 is failing to install . It says I'm missing CMakeLists.txt file. This file exists in the ControlBlock2 folder, but not the ControlBlock folder. I tried using it from the version 2 folder, but no luck.

What kind of error do you mean? Can you post console output here?

This look like a really good idea. But after reading just some of the comments I would like to make these points.
1) can the software not be programmed in Python?
2) The Pi + Powerblock case to be on offer rather then 3D Print...
3) A kit or better a completed + tested version with all components switches etc.

193 comments means there are obviously issues with this product. Perhaps a re-vamp may
well be needed.

Re: USB-Keyboard with Arduino and V-USB library, an example

Vojtěch Míček — Fri, 30 Mar 2018 19:00:34 -0000

Hello, I try to use my Arduino Nano as virtual keyboard. I proceeded according this tutorial and use this library https://code.google.com/arc...
to make example compilable I added some consts before char variables.
After that code compile and if I connect USB to computer it's visible
like keyboard, but it doesn't write anything, even thou I remove part
with button and let it write Hello word every few seconds (using
millis).

Could anybody help me please, it's really important for me, it's part of my school project.

The new firmware works. I can confirm.

Could you post an image of your hardware setup here, please? The micro USB connector is supposed to *only* be plugged into the PowerBlock. You need to use a toggle switch that is connected to the two "switch" pins of the PowerBlock.

I installed the powerblock using your one line script and the power isn't working when plugged into the powerblock, and if I plug the power into the main port the pi starts up and then shuts itself down. I'm using a small rocker switch, I'm not sure if that's a problem. I'm not sure if it installed correctly and now I'm not sure what to do to fix this.

Re: Xarcade2Jstick – Map your Xarcade Tankstick to Game Pads and use it with RetroPie

DB Cooper — Tue, 30 Jan 2018 16:21:23 -0000

Me either, but I did find this comment on the XArcade site. (Possibly a recent add):

IMPORTANT NOTE: Do not 'Update all installed packages' under 'RETROPIE SETUP' as it will break trackball/mouse support! We are not aware of any fix if that happens other than to reformat/reinstall from scratch. You can 'Update RetroPie-Setup script' and the Update found under 'RASPI-CONFIG' however.

Thanks. I tried it last week (exactly the same way) and it worked.

You can find the hex file for the PowerBlock at https://github.com/petrockb....

Hope that helps!

I did finally manage to get this to build on my wheezy based pi, but it was a super pain to do because wheezy only goes to g++-4.8 I spent a long time fighting with it.

I used the laryx answer from this: https://stackoverflow.com/q...

to get the parts from a jessie build and then manually did the cmake setup with -DCMAKE_C_COMPILER= and -DCMAKE_CXX_COMPILER= definitions on the cmake command line pointing to the new 4.9 stuff. Just exporting CC and CXX in the env didn't work for me.

Hopefully this will help other's trying to get PowerBlock working on a wheezy pi.

You mention customization of the program running on the ATMEL chip by connecting through the ISP header. Is the default program contained on the ATTINY chip located on your github? I can't seem to find it.

Re: Tutorial: PowerBlock with RetroPie

petRockBlog — Thu, 04 Jan 2018 04:11:13 -0000

You need to use a toggle switch (and not a momentary switch). The behaviour that you describe very well suggests that the PowerBlock sees a "switch off" right after the boot completed and, in turn, it initiates a shutdown. Hope that helps!

Re: PowerBlock: A Power Switch for the Raspberry Pi

petRockBlog — Thu, 04 Jan 2018 02:44:52 -0000

The PowerBlock has 5V output pins (+, -). These pins are also switched by the PowerBlock. As long as the fan does not draw too much current, those pins could be used. The maximum current the PowerBlock can handle is 3.7 A - including the current consumption of the Raspberry! If you need more power you could use the output pins to switch, e.g., a relay. Hope that helps!

Re: PowerBlock: A Power Switch for the Raspberry Pi

Matthew Olsen — Wed, 03 Jan 2018 23:33:13 -0000

I've just received the power block and am building a custom case for my setup. Since the power block takes up the necessary GPIO pins for running a small fan, is there an alternative way to power a small cooling fan?

Re: Tutorial: PowerBlock with RetroPie

veli — Tue, 02 Jan 2018 05:18:19 -0000

I have completed all steps above. when power socket is switched on my pi doesnt power up. I have to push my momentary push button on for it to start up. The led will fade in and out slowly i can see my retropie splash screen then the led will change to faster fade in and out then completely shut down. What am i doing wrong here?
