Good News on 1088XEL PIC MCU programming

 

Over the last few days I’ve been working on a pdf/video combination that would give the 1088XEL DIYers more information on how to program 1088XEL PIC MCUs using a PICKit3 Clone programmer and the MPLAB X IDE software. Finally got most of it done now.

Currently I only have a handmade adapter for 8 and 18 pin PICs, but I should be recieving a new PIC Adapter designed especially to handle all four of the PICS used in the 1088XEL build. Once they are in and I have one assembled, I’ll finish the group of videos with a short one on how to use the PIC adapter with both the JOY2PC and PICKit3 programmers.

In the meantime here are the pdf/video combinations I currently have available.

Restocked, reloaded and something…… something else…..

Well……  I’ve been restocking pcbs and some parts.  Mostly parts that I have to order on Ebay and get from China.  Those typically take upto three weeks to arrive.  Other parts that I can get state-side within a week I’ll wait until I have an order in.  Still have a couple of boards to come in.  Namely the final board I need for the RD Eprom burner board kit.  Should have that by the end of the week though.

The 1090XLR project is in full swing.  I’ve got a website and forum up for it at this address. 

The one thing I’ve been planning has not happened yet.  I was planning to start the new year with a website redesign.  Hasn’t happened yet as you can tell.  I’m still working on it.  A little at a time.  I might have it done for Jan 1 2018.  🙂

Yesterday, website nuked by mistake…..

It was bound to happen at some point.   No person is perfect.  In fact most people would agree that if they do most things half right most of the time they are satisfied in their perfection.  Well… I guess I am satisfied.  🙂

I was in the process of trying to add additional features for the 1090XLR project to the domain when I veered off course and started doing clean up from past mistakes.  I had some orphaned databases and folders that were left over.  The orphaned databases were easy to deal with.  But then I discovered a scripted uninstall app in the Cpanel of the website domain manager.  It was listing several lingering breadcrumbs to failed or abandoned projects.  So happy that I had an easier way to clean the site up, I started selecting the orphaned breadcrumbs for deletion/uninstalling.  Only the listing was slow in updating and in the process I selected the active app for deletion.   WTF???!!!

Four hours later I finally had a functioning website back.  Fortunately I had done a brute force backup of the website, late last November and so I was able to use it to get back up.   So right after I finish writing this post, I plan to make a backup both on the domain and off-site.  I really did have other things to do yesterday and I don’t want to repeat this.  Especially since there are so many other things to only get half right most of the time.  🙂

2nd Massive Earthquake to hit Oklahoma

I don’t normally post off topic, but Oklahoma just suffered it’s second massive earthquake in less than six years.  ……well massive by Oklahoma standards.  Preliminary 5.6.

I was on my workbench when a minor tremor began.  I thought at first that my cat had headbutted my leg.  He’s prone to do that when I’m ignoring him and I was.   He weights at least 12 pounds, so yes he can make the chair shake when he does that.  But the tremor continued and when I looked up he was in the doorway of the room, coming into the room, no where near my leg.  Then the tremor got rougher and I began to hear things in the kitchen rattling.   My magnifying lamp began to sway in time.  My lcd monitor tipped forward and then back.  Suddenly there was a sharp jolt, a rolling sensation and then a smaller jolt.   My cat jumped,  spun around and dug his claws in for a hasty retreat from the room.  I knew then what it was.

In the rest of the house I could hear things shifting and falling.   The trailer continued to rattle and quiver for a couple of minutes longer, but the main quake was over.

It’s been nearly two hours now.  There seems to have been a couple of minor tremors since, but it maybe just my nerves.  Reports are slowly coming in.  Some damage in Pawnee, but so far no injuries.  It appears that the epicenter was close to the town, just like the first one that hit very close to the city of Prague Ok in 2011.

No damage at my house, my cane fell down in the living room.  Mostly jangled nerves seems to be the only real damage.  Let’s hope it stays that way.

I’m thinking about changing my avatar.  I used to think tornadoes were the norm.  Now it’s getting to be earthquakes.

Merry Christmas: Beta 3D Atari Cartridge Files

XF551s

As promised here are the beta 3D Atari Cartridge Files.  I say beta since unfortunately my 3d printer is being cranky and I am not able to print out a prototype.  So I advise you to do that before you send these files for production.  I’m not responsible for that 1500.00 bill from the plastics manufacture.  🙂

Inside the zip file you’ll find the source Solidworks model file, a pdf with the max pcb dimensions, various .jpg views and a .step and .stl versions of the source file.  Your 3d printer should be able to do a resolution of at least 1 mm.  I think I took out any critical less than 1mm dimensions.   This is a generic shell.  I am still working on a shell that will allow a top pass-thru.  It should follow this version closely, but will have some differences of course.

I give you permission to use these files to produce cartridges for commercial sale and private use with the stipulation that you attribute authorship to me and send me 1 complete item you are selling and 1 empty cartridge.  You can modify and distribute these files only if you also include the source zip from me and again attribute me as the source for the modified files.

After a request to add post and hole snap together, I played around and came up with the first modification.  Not sure how well it will work.  Please post any comments to this here.  Changes, requests etc

Warning: XF551 board write/format error

XF551s

Just when you think you are riding high and taking no prisoners.  (Yea, I shoulda known)  I have discovered a fatal error on my XF551 boards.  I believe it affects both versions, modern and original.*

It’s not that it can’t be fixed, but it’s the loss of trust and extra expense I hadn’t counted on that’s going to hurt me most.  Not to mention the hassle to my customers.  I have posted on AtariAge.com and will try to send notification to those who have purchased via the email used when they purchased.

Any new boards sold will include the fix.

Damn….

*Update…..  At this time it seems to be only affecting the original power supply boards.  Possibly a consequence of the anemic power supply design for the original Atari XF551.  Anyway some people are reporting the problem, others are not having a problem.  To date noone has reported the problem with the modern power supply model.

New projects and ideas

Well…..   the new year is nearly two months old now.  I’ve been in my new house for a little over three months.  Things are beginning to settle into a routine.  Things are becoming comfortable. 🙂

I am toying with several ideas for my next projects.  They seem to be a split between electronics and 3d design/print.  I suppose I’ll add to and edit this list some.  But for now….

Electronics                  3d design/print

New Town, New Home and working through the boxes

Well I’m back………  Almost.  🙂

I’m done with city life.  Small town is more my style now.  I’m sure I’ll miss somethings about the city, but being able to get from one side of town to the other in 10 minutes I don’t think will get old anytime soon.  Owning my own home is nice too.

Boxes are going to be my life for the next week or two.  Just when I think I’m making headway, I find another stack that was hidden behind the one I just emptied.  I swear my apartment was only 810 sq ft.

The kitchen is almost finished.  The bedroom, living room and hobby rooms are almost done too.  The guest bedroom seems to be the collection point for all uncategoried items.  One of these weeks I’ll start in on it.

BitsofthePast.com is open for business again. 🙂
