Picaxe 'No Hardware Found' and Breadboard

Some of you may remember way back when I had tons of problems with programming my picaxe. Well, they're back with a vengeance.

I recently got a breadboard and decided to try programming my Picaxe-08M with it. I followed this image:

(http://www.thebackshed.com/windmill/articles/images/PicAxeCircuit.gif) and looted the headphone jack from my old non-working board. The 5V I have is a new 9v battery with a 5v regulator (I know, not very much current, but enough to program, right?). My voltmeter says it's definitely a constant 5v. Requisite blurry photo with MS Paint labels included below. 

When I try to program it with a serial cable, I get "Hardware Not Found'. Am I making a dumb mistake or is the technological universe conspiring against me?

I still haven't fiugred it out, but I was able to take a picture with a digital camera. I would be forever indebted to you if you could figure out what I'm doing wrong. The wires to the thing that connects to the cable are taken out, but they are there and definitely have a signal.

Did you move resistors around in between taking initial and latest photo? The reason I'm asking is because in latest photo, your resistors are not connected as they plugged into separate raws.

Are your jumper wires all ok? Can you check if picaxe actually gets power to it by touching it's pins with multimeter probes?

The picaxe is definitely getting power, but I guess I should probably check all the other jumpers too.

Cannot see on photo: are both power-ground rails on sides connected to power supply? 

On the left side of the breadboard under + I have the positive lead from the power supply and on the right side under - I have the negative. 

Hey Guys,

I am currently writing a picaxe book and the first installemnt of it is available on my website. It has all the basic a information in there and a lot a great general inforamtion that you guys should see. Please check it out. You can find it in the prop how to section. Comments welcome.I in the process of building a few robots with my son which I hope to show you soon.




Are you sure you connected the pins to the jack correctly?


Yeah, I'm pretty sure they're right. When I get a chance though, I guess I'll switch them around a few times to make sure I didn't screw up. From what I'm seeing, a, b, and c in that image correspond to 1, 2, and 3 in the image I posted.

In addition to rik, using a 9v battery will work fine(with a 5v reg of course). 9v's are not great for powering motors, I wouldn't worry about powering a proc though. As a test, I powered several picaxes and arduino along with running sensors and a bluetooth serial device off of one 9v battery with no problems.....I left it running for a bit if I recall.
