£200 for a smd rework kit, £50 for a scope, £130 for the vcos for both wavebubble kits, $150 for the parts from digikey (now that i did have to pay charges) and all the other little parts, solder paste, liquid flux, etc etc. So its a seriously expensive project. Its not something to undertake lightly. I'm at the programming point on mine and a know *nothing* about compiling, commenting out et-al...So, you have to put a lot in..... Just go buy a banned fixed frequency jammer, or search and build a proper "boy's toy"...
Its a real shame that we cant do a group buy for the parts.
It would probably work out no cheaper with minimum parts quantities etc but if anyone is willing, i'm game....Would certainly make it easier for people...
I thought about the same, especially the VCO's and amplifier pieces, since they cost nearly 60$ by themselves.. From your currency it appears your in the Uk. I feel sorry for you, as it costs nowhere near that much being here. My totals so far:
100$ from amazon for Aoyue Digital solder station (works great, and I needed it for work anyway)
60$ for parts from newark electronics (newark.com)
10$ for parts from digikey (Newark is much cheaper, i only ordered parts from digikey I couldn't get at newark)
25$ for solder stencil
10$ for battery
8$ for solder paste
I still haven't ordered the VCO's yet but will once I build/test everything else. You know what it comes down to though, is the following:
1.) You get the experience of building it yourself, and learning a lot of electronics knowledge
2.) You build something that is programmable, COTS equivalent would cost probably 200$ or more
3.) You get to have fun!
The problem I have with the group buy idea is that you have to get people to seriously commit to doing it, else you're stuck with all the cost. I was going to do a group buy deal on boards, but theres no way to guarantee people end up paying.
