Made a little PICAXE programmer board...

Should work, haven't tested it yet... I'll be using it with a 14M2, at least initially.Built with what I had on hand. 7805, 100nF Chiclet caps, resistors, and perf from Radio Shack. 'Sink for the 7805 from eBay. Headphone jack from places unknown. The 20pin DIP socket started out as a 28p socket that a friend gave me; I cut it down with scissors (frighteningly effective). I'm all out of 10K resistors :( but I had an extra two 22K's and a 100K which (according to The Interwebs) was good enough in parallel... ~9.9K instead of 10K, I really don't think the chip will notice or care.I'll build a better one if I can get my hands on some ZIF DIP sockets... I know that the regular socket I'm using now will wear out pretty quickly. This was built for a time-sensitive project though, so I couldn't wait for cheap eBay sockets to arrive from China or Hong Kong. Should work OK for a while...Pix (huge, as links) -- (1) http://i.imgur.com/fbS7Jlf.jpg (2) http://i.imgur.com/9UoNInv.jpg (3) http://i.imgur.com/UbJKpk9.jpg (4) http://i.imgur.com/r54d0b8.jpg (5) http://i.imgur.com/aSnYjXe.jpg (6) http://i.imgur.com/D1iqhzu.jpg (7) http://i.imgur.com/P4GEq0M.jpg

Just a personal opinion.......

Please can you attach the pictures as .jpg or similar.

Lots of us do not like using external, and possibly dodgy links.

Tried to upload several times, can't make the blasted thing work :(FWIW, Imgur is /not/ a dodgy site... should be A-OK to view them there.

Good work, laserhawk64. Homebuilt boards are great. I've got all the parts to build a universal programming board for all the M2 chips per IronJungle's clever flip flop design: http://www.picaxeforum.co.uk/showthread.php?21704-ZIF-socket-multi-chip-programmer-Not-a-dev-board

My only change is that I ordered a narrow 40-pin ZIF socket so there is no pin overlap, the top 20 pins will program 08M2, 14M2 and 20M2 chips, which all have the same power & serial in/out pins. The 18M2 has a unique pin configuration so it will plug into the lower 18 pins.

The OP may not have options, but he will certainly get more views for his work if the images are attachments, not links.

Good idea for you to move on.

If OP was generous enough to share his project why do you and others think it is OK to hammer him .. if you don't like the link then it is simple ... don't go there ... and move on.

OP did not ask for help or opinion or for a million views ... he simply shared his project.

My personal opinion:
I had rather have links - not a lot of photos to scroll through - especially if several people reply with quote and don't eliminate the photos.
Thanks for posting this laserhawk.

Actually the links opened 10 times faster for me than a photo hosted on the forum do.

Personally i hate the thumb nail format the forum has for attachments, where most other forums allow a reasonable size attachment display format, which i find much easier to view a thread without the need to open each thumb nail.

@laserhawk

Thanks for sharing. The links work fine.

I have done several similar boards but like ERCO also used ZIFF sockets to reduce stress on the chips when inserting & removing them. But many times I still find my way back to just setting things up on a large breadboard.

Sorry I have not replied since that last post. I am only on sometimes... don't hold it against me, please! At any rate, the board as originally built did not work. The headphone/programming jack had half its pins in the air... and I had forgotten a wire connecting the ground on the jack / resistor array to the ground on the board! (How in blazes did I manage *that*...? Hmph.) here is the completed, tested working version, just used it to program a 14M2 and it worked --> http://i.imgur.com/gty5fKH.jpg (No schematic, sorry! I'll draw one up, along with a BOM, if there's significant demand...)

Personally i see your project as rather agricultural and not very elegant and any kid with a soldering iron could design it, but i also give you credit at having a go and showing all of us your work, as we all start somewhere and are proud of what we do when we do it.

Im sure there's many out there like yourself (and i was one, once too) that tackle a project and proud to show all, but understand criticism like mine just makes you want to achieve a better standard and a better quality.

A+ in having a go.
A+ in sharing you project (and well done there)
C? in project quality (but we all start somewhere and get better from there)

Keep at it and develop your skills. you will become good at them with practice and more projects, its just a matter of trying projects and developing as you go.

Best wishes for future projects.

Look forward to see your next project improvements.

Dont give up!!

Nonsense and not inspiring in any way. Why would you bother posting such harsh rubbish? Please allow new people to share their excitement about their projects without any criticism. It's new to them, and they accomplished something they have never done before. We don't care if you think it's elegant or not. He built something from scratch and it works. Nurture that achievement, don't discount it. Please stick to positive reinforcement, especially with new people.

Laserhawk64: keep up your excellent work, there is lots to learn! Please continue sharing your projects, it will be great to see what you do next. BTW, I'm a Carolina boy myself, born in Charleston. :)
