  IR LED ion charge pumps with Scalar Conversion Unit and FPGA high freq pulsing
Posted by: MichaelTuckwell - 04-24-2020, 11:16 PM - Forum: Show and Tell - No Replies

Infrared LED ion charge pumps with Scalar Conversion Unit and Alchitry Au FPGA high frequency pulsing. Storing multiple ion charges into capacitors.

This construction was designed, programmed and built by me but is based on the work and theory of my friend and mentor Nigel CHEESE who has been teaching me about magnetism and the Scalar Wave and how LEDs can be used as power amplifiers.

There are three earth connections, an infrared solar effect and 21 3.3V PWM channels shunting ions from the H-Load panels into high voltage capacitors. There is no external power source except for the lithium battery powering the FPGA.

I'm no PhD physicist so I may not be able to explain the physics very well, however I love programming and building.

Please enjoy the demo and comment.

  An Update and Looking for Moderators!
Posted by: alchitry - 04-17-2020, 04:27 PM - Forum: Announcements - No Replies

Hey Everyone!

I'm really sorry for my long absence and the shambles I've left the forum in.

I just went through and attempted to remove all the spammers. I've also now made accounts require approval. This will be a way for me to keep the forums clean while gauging how well the anti-spam registration measure work.

It's also very likely I deleted some valid accounts. If that happened to you, I'm sorry and please re-create your account.

Currently, I'm the only moderator on the forum but I would love it if we could get some of you guys to help keep spam in check. Shoot me a message if you are interested in becoming a moderator.

As you may already be away, we are now working with SparkFun Electronics to have them manufacture and distribute our boards (find them here). That means I'll have a lot more time to work on things like the forums, tutorials, the IDE, and new boards.

SparkFun estimates they'll have the first batch of boards done in May. These will be basically the same boards already had out with some minor updates. The Au and Cu will now have a QUIIC connector to make attaching many of the boards SparkFun sells easy. They both also have a fix for the USB-C to C issue currently plaguing the boards. The Io Element will have pulldown resistors on all the inputs which will help the Cu since it doesn't have them built into the FPGA. No more having to fake pulldowns with an inout.

I'm currently in the process of working on another video and plan to get these rolling out more once other things are less demanding.

I promise to try and check the forums more! There are a ton of posts on here that I need to go through as well. It's really great hearing from everyone using the boards!

  Running Achitry on VirtualBox
Posted by: prebys - 04-03-2020, 03:04 AM - Forum: Tips and Tricks - No Replies

I'm stuck home because of the quarantine, so I needed to install Windows 10 on VirtualBox on my iMac to keep developing stuff.  Getting Vivado and Alchitry Labs to run was pretty straightforward, but being able to download the .bin files required some extra steps regarding the USB interface.  I made a complete set of notes here.


  Please, please, PLEASE kick off the spammers!

Is there a moderators somewhere out there?

This is a great product, and this forum used to be very useful, but now it's virtually useless because of all the SPAM.

Please kick these idiots off.


  Core naming bug - Alchitry Labs V1.16
Posted by: IvanLentil - 03-29-2020, 02:10 PM - Forum: Tips and Tricks - No Replies

Hi all,

this bug applies in Mojo projects with Xilinx ISE. I haven't checked if it affects with Vivado.

If you use Coregen to build a core, Alchitry Labs uses the default name for the core even if you use a different name when generating it. This can be a problem if you use more than one variant of the same basic core - for example if you use more than one configuration of block ram.

A simple workaround is to exit Alchitry Labs and manually edit the project file to change the core details.

  Re-flashing a Mojo V3 board
Posted by: Major Havoc - 03-16-2020, 11:17 PM - Forum: General Questions - Replies (6)

Through my own stupidity (connecting more than one board at a time to the computer) I have clobbered the flash loader on my older Mojo v3 dev board, along with the default examples added to that original flash. 

Maybe my search skills are lacking, but I cannot find either the original flash file, or instructions on how to flash a board that is not responding to USB. I am guessing I am going to have to add pins to the JTag and connect and refresh that way? 

Any help would be greatly appreciated.

  Alchitry Labs installation corrupt
Posted by: sambuls - 03-12-2020, 07:26 PM - Forum: General Questions - Replies (2)

During the installation of Alchitry Labs or Loader, I receive the following message:

---
The cabinet file 'disk1' required for this installation is corrupt and cannot be used.
This could indicate a network error, an error reading from the CD-ROM, or a problem with this package

Re-downloading does not solve the problem


  lucid always block with timing parameters
Posted by: sambuls - 03-09-2020, 03:11 AM - Forum: General Questions - Replies (1)

I created a new clock using the 'vivado IP catalog - clocking wizard'.
Can I use this new clock to run an always block in Lucid?

I could not find any solutions in the 'lucid reference PDF'...
