Life, all life, is about asking questions, not about knowing answers. Its wanting to see what's over the next hill that keeps us all going. We have to keep asking questions, wanting to understand even when we know we'll never find the answers. We have to keep on asking the questions

Arduino ISP bootloader problems and solutions

Just started learning to use atmel chips and using my arduino mega as an ISP programmer and thought I would post a quick list of the main problems I had and how I fixed them in case anyone else is getting stuck like I was.

Now I know all the problems a quick check list should be something like this:

  • Check wiring connections / basic power etc



Decided this year i would treat myself to a new oscilloscope as all i had before was a really old analog telequipment d61a. Well after a lot of research i decided on a  Rigol DS1052E digital oscilloscope. Today i finaly got around to testing it now thats its arrived, looks like all the reviews were right its a lovely bit of kit. All i need to do is find time to load a windows machine up and test the data logging software.

So decided to finaly start and build a RepRap 3D printer.

Today i researched and then Ordered the 5 x Bipolar Stepper motors needed for the project.

  • 5 x Bipolar 48mm Stepper SKU:3302    £79.99 inc packageing (source)


Pre 18/12/2011

Received my order of spares from Needed two spare Keda KD2217 propeller adaptors. Tip never do them too tight or they will strip when undoing as only aluminium, don't ask me how I know :). Rest of this order mostly spare wire & connectors ready for my HK-Drone style tricopter I plan to build next.

OK got a lot of stuff done:
* soldered up all connectors on motors and esc's
* mounted missile switch on quad copter
* didn't have any 10 awg wire so ended up using 12 awg and 16 strappedaped together just to be safe
* build power cabling system and wired it to missile switch
* tested all motors and esc's this included motors and ducted fans ready for hk-drone robot
* build a simple header so I could run all motors using one servo signal

Most parts have been ordered now this is a ruff list of parts i bought

1 x £4.99 ABS box MB5 (maplin YN40)
1 x £2.34 16/0.2 wire 10M blue (maplin FA27)
1 x £2.54 16/0.2 wire 10M black (maplin KR31)
1 x £238.54 SPEKTRUM DX7 DSM2 2.4GHz TX (mode 2) + 2x AR6200 RX (off ebay wanted for RC modal helicopters anyway, also have a old Futaba 6 channel skysport 6 (6YG-FM40) MODE 2)


Just spent last ten minutes installing my new Alienware laptop screen and all works which is great as i can now see the whole screen again yay.

Was dam fast delivery as i ordered screen from ebay laptopservicecenter (Dallas, Texas, United States) on friday 01-01-2010 at 7pm and it had arrived at my house in the UK by wednesday 6th at around 1 pm.


Well finaly got xen running again, decided to go with ubuntu 8.04 as i know it had less xen bugs and didnt take me that long to fix everything. One item left to fix and thats finding out why vnc and my HVM domain wont start so cant access windows domU but thats not a problem as dont use much yet.


Dam it, just had to order myself a new laptop display as my nice Alienware laptop now has vertical lines. Think i must have closed the lid to quick which has caused circuit in one area to disconnect from the glass screen :(. Thats about £166 i didnt plan on spending now i just have to wait for it to arive from the United states so i can fit it, Shame i couldn't find a UK supplier.


F##ck me i finally got XEN running a windows HVM guest and allowing me to access its VNC connection remotely (my servers headless so no SDL=1 option here). It took awhile but after abit of googleing for extra config options, a few cat and tail -f commans later i worked out all those dam cryptic xen error messages.

Now i can finnish setting up a test network and start playing with setting up honeypots and going through a pentesting and security course i found.
