Hello gang
I am trying to make a JDM PIC programmer on vectorboard and looking for someone who`s done
one or can help me with the lay out as i can only find
a layout for the PCB. I would be Very Very greatful for any help given.
From
Matt. who`s new to this but not to makin tunes!
Thats wicked i needed to see the underside of it. Thankyou very much for taking the time to help i may need it again, hehe.
Matt
is this one different ???
it is not the same as the scematics shown on the site…where are the zeners ??
…where are the zeners
they are there, cept 2 of em are stuffed horizonitally by the looks of it…
I have had a PCB made now anyway ;) but have allready snaped 2 drill bitz >:( going to get a better drill i think.
Matt. AKA Q-Trax
make sure u get the carbide type - u can get resharpened ones for pretty cheap. Also a drillpress will help ALOT…
best…

I was using a power drill though!!!
were would i get carbide type ones from that small?

Opps
heh, power drill on a pcb eh 
- sounds dangerous!
I’m using a dremel for pcb work…
Depending on where ur located, you can get small drillbits from most electronic stores, or ebay for instance - just type ‘carbide drill bit(s)’ or summin - i’ve seen loads about on there…
Or, for the cheaper option get a jewllerers drill, or alchemedies (spelling?) drill - u can pick on of these up for a few quid…
Drill sizes, 0.8mm upwards should be fine…

Went to B&Q and got me a dremel today and drilled my board in about 5 min`s wicked!!! That power drill was costing me to much loot in drill bits. I will be attempting to program a chip tommorow so if it goes tits up i will be sure to holla.
Matt
just make sure you are following the “how to program” page on Thorsten’s site ‘to the T’, cos I thought I was, and didn’t realise that I had skipped a few steps (configuration of IC prog) cos the instructions had been updated since I last used IC prog. It’s usually something simple that has been overlooked that halts these projects!
If you want a real good solution for a drill bit that you won’t break then get on down to your dentist.
They have some very nice boring / drilling bits and they are real tough .
Best keep your mouth shut while you’re there though :-X :-X :-X
BTW
Don’t you hate the way when you tab the cursor goes out the window to the post option >:(
anyhoo
I use a portable drill for my boards. But I leave the drill on the table and push the board against it
That way you don’t have the whole weight above the drill bit

Hey Ian
Tried using the modify button ???
Its at the top of each post!
Yeah, I just broke down and grabbed a Dremel a couple weeks ago and don’t know how I got by this long without it. I already had a small bench drill press.
By the way, Dremel had a pack of 5(?) bits that I bought with the intention of breaking, and was never able to break them. They are a 32nd of an inch or something, and they actually have a pcb in the picture. I had to drill probably a few hundred holes for an EPROM programmer, and they were perfect for everything but the regulator and the D-Sub pins. For those, I used a Dremel “ball tip” burring bit, which was a bit larger. I see those recommended as pcb drills a lot. The real ones are for dentistry or something.
I’m sure my Dremel bits are dull as crap now, but they didn’t break. I’m going to start keeping a bunch of tubes of them.
- take care all,
George
Just for documentation: here another easy solution to realize the JDM circuit on vector board: just draw the required connections on the board and wire it like shown in the schematic.
Thanks to Leo!
Get down to Maplin and get a drill stand ;) £35 turns a dremel into a upright drill i still have not had time to program my first chip yet so i will updat you guys.
Peace Out
