Good read on mechanical parts, some metallurgy and a few nuts and bolts 🙂

(- Of course you need prior knowledge on the subject and some imagination as it’s not quite the real deal -)
Thanks ARM/mBED for the letting us play with your toys

This article is probably the best I read lately!

Ok, considering that I invested some time/ money and effort in my listening room (see older post) I thought it might be a good idea to measure it.
The first sweeps using a simple 20-20k Hz sine generator showed a room resonance around 60Hz that was quite annoying! Unfortunately there was no more time to improve anything – the room sits in my parents house – Romania, and I sit in Birmingham UK. But there is still enough to improve!
Lately a nice piece of kit caught my eye – XTZ room-analyzer. Looked like what I needed to finish up my room design, so I bought one from  Audiosanktum.co.uk – the main retailer for England.
The experience I had with it proved positive. It’s very simple to use, gives good – similar results on consecutive measurements and has other features except room-analysis – you can do near-field measurements with it, meaning you can measure the response (past crossover) of each speaker driver.
There are a few other nice things you can use it for but I must test further myself.
All in all it is a good investment if you feel you are not getting the most of your audio set-up. It’s also a very good tool in case you plan to create a dedicated listening room in the near future!
Here are the pictures of my listening room:

This seems like a very good way to learn more about your RC car and develop some tuning skills. Will start building one soon and update the post!
Artaflex 2.4GHz and the nifty PSoC
Posted: February 11, 2011 in The amazing PSoCTags: artaflex, hub, node, PSOC, wi-fi
HI!!!!!
This is a working example of a PSoC project using the wi-fi from Artaflex. Â It’s very hard to find a simple example as this one so I post it here. The important thing to remember is that it’s my first fully working code on this RF module AND I did not implement any feature yet. unfortunately I cannot attach the project, so use this link from PSoCDeveloper:
http://www.psocdeveloper.com/forums/viewtopic.php?f=3&t=7393
Now, get the PSoC set it on 5V, connect 100ohm resistors and 3.3v zener diodes to Port2 pin 7-3 and feed the RF with 3.3v from a separate supply. Remember to keep grounds connected.
If you do not want to go trough that, although it’s the easy way BY FAR!!!! you can do this:
1- use 3.3v on both PSoC and RF — unless you have a 3v LCD you MUST NOT use the display. Because reading data back from LCD at 5v will mess around with  the ZEN state of the circuit 🙂
2- use an LCD driver- 3.3v -> 5v.
3- NOT use an LCD but some LEDs you set yourself.
