I bought a Midipal kit on its first few days of release to work on with a friend ( a 90% him / 10% me arragement !) well… we have finally got it up and running.
It has already been wrapped up for me for christmas now (having to build your own presents, clearly the Elves are on strike ) so no more playing until the 25th, but I thought I would make a few additions on here regarding general observations.
1. the step by step guide is in a really good order , it gives you optimum room to work around the small parts…go with it.
2. in my friends opinion, adding flux to the pads first yeilded best results when soldering.
3. the part SW2 (small switch) is a complete mystery, it only JUST fits on the pads …and then there is nomention as far as I can see about what it does, interesting , any throw any light on it? I’ve just left it alone and Im fine, it sits inside the completed case to I will probably never use it again.
4. The screw threads to hold the case together are a mystery, no matter which way I screwed them all together, I was always left with a huge gap between the maximum tightness and the case…it looks like the longer screws were the wrong type, but this could just be my unit?
5. I can confirm that the tinyisp loader from this shop works http://stores.ebay.co.uk/Arduino-Robot/_i.html?_armrs=1&_dmd=1&_from=&_ipg=30&_sasi=1&_sop=1&_trksid=p4340&_vc=1 good rpice too and only 12 days to the UK from China.
6. It is worth noting that there is no description as far as I can see about the pinout for the Midi Pal… I can confirm that ground is the bottom LEFT pin on the Midipal with it facing towards you and that on the tinyISP above, that relates to having the cable so that the wire with the red ink on it goes on the left also.
7. Also on this Tiny ISP design it is worth mentioning that there is a little jumper pin on the TinyISP itself…this has to be REMOVED for the loader to work.
8. I followed someone elses thread to find the excact commands to type, however in the instructions given some of the names have version numbers in the real downloaded hex’s… therefore, watch your filenames.
9. oh yer…we probably got it right first time but we couldnt see it had worked until we turned the little trimmer screw A LOT…there are many many turns on this thing until you begin to see the LCD working…therefore we flashed it twice before I realised i could JUST see a little text onscreen.
so thats it no big bothers really…have a go ! and BIG BIG props to Olivier for his hard work in bringing this to us…I will surely be building again when he releases his next tool to go with my midipal and shruthi.
