Nice build! could you please tell me what trucks they are? Look very cool! Thankspsychotiller wrote:That's going to look pretty cool. I do agree that things might get dirty. I made a wood enclosure for one of my boards too and haven't been able to figure out a decent door solution...
Thats the Lagrange/Surfrodz kit. https://redrockboardshop.com/store/product/32-pro-setPracticalProjects wrote:Nice build! could you please tell me what trucks they are? Look very cool!

You could use a heatgun and an abs sheet and heat every inch and bend around a mold.chuttney1 wrote:@carbon, totally would do it, but I don't know to build a vacuum table so im stuck using fiberglass. My past experience with fiberglass is it is really tricky to work with for beginners and if you have access to vacuum forming stuff with fiberglass or plastic do it. Makes the final product look much cleaner.

I got the stencils from OSH Stencils. They have the choice for either 3 or 5 mil thickness in laser cut Kapton tape. From start to finish, 14 hours for two boards. Only because I did it in stages to get a feel for the process. I have no pick and place machine so it added time. Hot air gun is quick once solder melts with a few seconds. I estimate it would probably be closer to 2-3 hours per board assuming no problems with the application of paste solder and everything went well. I did forgot to mention I used the leaded solder paste because I fear I'm going to burn my stuff. The lower melting point of leaded solder makes it slightly easier.torqueboards wrote:Nice work! Where did you get your stencil made?
How long did that take you? Looks fairly quick with that hot air gun?

The past few times the VESCs I have soldered work, but encountered the DRV8302 error. Every time I try to replace the DRV8302, one solder trace lifts off from the board forcing me to solder a new one. Most recently, I have encountered the openocd error trying to upload the firmware to the VESC and have asked Vedder for help. My first stm32f4discovery board had the MCU flashed with the VESC firmware when I did not remove the CN3 jumpers. I thought this was a problem, but was not the root cause of the openocd error. I have gone on STM's website forum for help in looking for an answer. What I found is the openocd error can be cause by a hardware, USB drivers issue, or relabeling the SWD ports as GPIO on the Discovery board. I decided to get another stm32f4discovery board in case the first one I have is bricked but highly unlikely. I have eliminate probable sources of the error relating to the USB driver as I am able to connect to the Discovery MCU when writing the openocd script. This leaves me to believe the real root of the cause of the openocd is hardware related to the something on the VESC I have soldered. The voltage regulators do work as I have set up a systematic process to ensure one component is not mixed match with another during the placing of SMD parts on the VESC before hot air soldering. At this point after having 3 VESC I have soldered not work while reusing some of the old components from previous sudo-failed boards and from a financial perspective, Im just going to cut my loss and get a fully working/tested one.
I don't think it would be necessary to do this method as Vedder does address the stm32f4discovery udev rules with the file he has. I did check the code and it seems fine. My openocd error is now a problem with transport, but Im not sure what is really wrong if everything else is alright. I am using VMware on windows 7 64-bitjamesonotc wrote:
OpenOCD error is possibly due to you need to install what is called "synaptic package manager" on ubuntu in order to install openocd dependency prior to loading the firmware.... I noticed that after installing synaptic, then installing OpenOCD from there it worked. This is something I have tried to bring to Vedders attention as I believe the guide may need to be modified for fresh installs of ubuntu.
you can download synaptic package manager by finding this in the ubuntu application manager.
You can see the install instructions for openocd here: https://help.ubuntu.com/community/OpenOCD
it clearly states int the guide "Installation Instructions
Look for the package named openocd in the Synaptic Package Manager and install it."
