I bought this kit for two reasons. The first was because I had recently read about the Atari Punk Console. It seemed like an interesting concept that I wanted to play around with. The second reason for the purchase was wanting some experience with soldering and assembly. I can say this was a great entry point with the documentation that was provided. Overall, I'm extremely satisfied with my purchase. There was also an issue where the USPS had temporarily lost the package. It showed as delivered, but was nowhere to be found. I contacted the seller and was responded to right away with suggestions. After notifying the USPS, the package made it to me. I would definitely considering buying from this seller again!
I need something to test little switch mode supplies on their pcb before other parts are added, this is ideal for this. I like to think of this as the reverse of a current controlled power supply, you use a current controlled power supply to control how much current is input into a device, you use this to control how much current is output from a device.
This is a great little kit. It is arranged like something your would buy from Heathkit in the 80s. The parts are well packed and professionally organised, the instructions are super clear and it works.
For a few dollars more some standoffs and an acrylic plate based "case" could be added (http://dangerousprototypes.com/docs/Sick_of_Beige_compatible_cases).
Using the supplied model I created an acrylic base plate, download it from http://www.thingiverse.com/thing:754623
I purchased these for use with Linux firewalls providing VPN tunnels between locations. It works extremely well and does just what it say it will. I ran into some issues, but none were the fault of the TrueRNG. I highly recommend it.
The TrueRNG2 is fantastic. It generates about a gigabyte of random numbers over about 6 hours that passes every test for randomness that I try. Dieharder, FIPS, ENT all say that the data is indistinguishable from totally random. I use it to keep the Linux /dev/random pool of entropy full so that when I generate gpg keys there is no delay waiting for random numbers. With this you never have to worry if your psuedo RNG can be broken or sequence predicted. Goodbye generating randomness with SHA1, SHA256, Whirlpool, Ripemed160 or other PRNG. TrueRNG2 does not get hot even when left in the usb slot generating numbers over night and has not shown any sign of degradation over time. The quality of the materials is good and solid. For the price there is nothing on the market that comes close to this device. My only criticism is that the schematics and parts list should be revealed so that us paranoid types can verify or replicate the device. This would probably enhance sales rather than detract from them.
