I'm not really sure what the problem is. Could be resetting it at the correct time. Although now I'm not sure if I've broken it. I tried my USBASP cable to repgoram the bootloader. I'd read somewhere to try that. Not when I try to do anything, even with the USBASP, it says it's not responding :S Me

I was getting an error trying to reflash the bootloader but I fixed that. I had to update the firmware on the USBASP using my Uno so it could set the clock speed when programming. Managed to get the bootloader working. When I try and upload a sletch now it says content mismatch. Me

Ok, it's working, but only if I upload it really slowly. Better than nothing I guess. Still can't get the FTDI to work. Me

Looks like it was the Arduino board. I had another Pro Mini turn up today. Soldered the program pins to it and the FTDI cable worked with no problems. Me

Got it working. Yay! I used AVRDude to burn the bootloader instead. Me

I've been playing around with the RF24Network now I have both my Minis working. Setting up 2 to communicate between each other seems straight forward enough but not so easy to do with more. The library comes with an example for multi node setup with a branch configuration but only for the child nodes, doesn't show how to do the base. I've got two sending some temperature information to a base now though. I plugged one into a battery pack and it's outside reading the cold temperatures out there now. It's in a plastic tub with the temperature sensor in its own so the heat from the other components doesn't warm it up. Hopefully it won't rain, I don't think it will be water tight. Me

My big protoboards have finally arrived. Time to figure out the layout. ┌─────┐ │ │ │ ┌─┐ │ │ │ │ │ │ └─┘ │ │ │ │ ┌─┐ │ │ │ │ │ │ │ │ │ └─┘ └─┘

My first protoboard for my LCD screen took hours to make. I assume it's for the world clock. I'm currently trying one of my Minis outside again. Transmitting temp every minute and also the voltage at VCC. Found a way to measure the voltage without needing to use one of the analog pins which is handy. I'm trying to use 4 AA NiMH batteries but take 3 different voltages off a 4 pack. Using 2 batteries for the radio (can't go above 3.6V), 3 for the Mini and all 4 for the temp sensor (that can't go below 3V). Me

I don't think I'll manage to do many long solder tracks. I might use a lot wires instead. ┌─────┐ │ │ │ ┌─┐ │ │ │ │ │ │ └─┘ │ │ │ │ ┌─┐ │ │ │ │ │ │ │ │ │ └─┘ └─┘

Good idea. Those solder tracks were a pain to do. Me

I think I might do one for a common 12V in and maybe a common ground. I've got a load of telephone cable and CAT6 which should be suitable. ┌─────┐ │ │ │ ┌─┐ │ │ │ │ │ │ └─┘ │ │ │ │ ┌─┐ │ │ │ │ │ │ │ │ │ └─┘ └─┘

It was looking neat on the smaller board until I remembered the transistors. I think I'll need to use the bigger board. ┌─────┐ │ │ │ ┌─┐ │ │ │ │ │ │ └─┘ │ │ │ │ ┌─┐ │ │ │ │ │ │ │ │ │ └─┘ └─┘

I saw a tip that looked handy for long rails like that. Run a ~~naked~~ bare (that's the word I'm looking for) cable along the breadboard where you want the track and solder along that. Easier to do and less solder. Me

Not a bad idea. I suppose then you only need to solder the connections and that keeps the wire secure. Unsure whether to go transistors standing up or lying down. Lying down takes quite a bit more space but I should have plenty to spare on this board. ┌─────┐ │ │ │ ┌─┐ │ │ │ │ │ │ └─┘ │ │ │ │ ┌─┐ │ │ │ │ │ │ │ │ │ └─┘ └─┘

What's this going to end up being? If you've already mentioned it, I've missed it. Drawings n' that

Standing up = better heat dissipation

Good point. I only realised the other week that the metal screw hole section could also be used as one of the pins so they can't be touching. I assumed it was just metal for the sake of being metal :$ ┌─────┐ │ │ │ ┌─┐ │ │ │ │ │ │ └─┘ │ │ │ │ ┌─┐ │ │ │ │ │ │ │ │ │ └─┘ └─┘

I didn't realise it was a pin either. Always thought it was for attaching a heat sink.

Makes sense now looking at PCBs where they're lying flat but with the middle pin at the bottom cut off. ┌─────┐ │ │ │ ┌─┐ │ │ │ │ │ │ └─┘ │ │ │ │ ┌─┐ │ │ │ │ │ │ │ │ │ └─┘ └─┘
