In 2013, Remco PA3FYM obtained the schematics of the radio and devised a modification where transistor Q17 of the VOX is re-purposed as preamplifier in the microphone audio circuit. It works wonders for your radio. For people needing a bit more visual guidance, below is a walktrough of how I did this to my Baofeng UV-5RA.
I went through all the struggles everybody else seems to be going through to get this screen connected to my Arduino Nano. I had the 5V to 3.3V voltage conversion problem, and the “only works with software interrupts” problem which makes the display run slow. The solutions are not complicated but not very wel documented. Until now.
For some reason I have trouble finding a document which lists the complete IARU Region 1 Band Plans. To end my “can I transmit here” quests, I’ve combined the information from several resources into a usable graphical representation of all Amateur Radio bands and modes up to 500MHz. I’ve not listed bands above 500MHz, please post links to those in the comments if you have them.
Exact use of a frequency may differ in your local region, so always listen first.
Lorenzo had a great idea. In stead if being one of those “having fun at the bar” ideas that never actually see the light of day, Lorenzo followed through. Did you ever have that urge to just take a gun and shoot that fly that is constantly buzzing around your head or food? Well now you can. Check out his invention at www.bugasalt.com.
Seeing his gun, I remembered making pea-shooters at high school from a roll of tape and a party balloon. I adjusted the idea for flies (smaller nozzle), and it works beautifully. It only holds one shot, and it looks not nearly as cool as the shotgun idea of Lorenzo, but if you can’t wait to start shooting those flies, here’s how to make your own low-budget, one-shot salt shooter. Enjoy!
My sisters in law bought a beautiful 2006 Toyota Corolla Verso. They could not get the iPhone to pair with the car’s Bluetooth system. The dealer told them that this was an iPhone problem, but after some fiddling, it turns out there is a simple workaround. If you want to pair an iPhone to your car, and the car says “pairing failed” as soon as you tap on your iPhone, this simple trick might help for you. This article contains detailed steps for the Toyota Corolla Verso, but on other cars this might work too.

Many Drobo FS owners out there who upgraded to Lion were unpleasantly surprised by the fact that their Drobo no longer behaved like they used to. After months, drobo released new firmware, but it didn’t improve things all that much. With the new firmware, the Drobo FS:
- is slow or entirely unresponsive, Time Machine backups don’t finish at all or take days
- doesn’t show up in the Finder of Lion Macbook owners connecting through wifi
- has a transfer speed of 20MB/s, even when connecting through GB Ethernet, regardless of OSX version (tested with Snow Leopard, Lion)
If you have one or more of the problems listed above, you will be pleased to hear that there is a “fix”, although it may not be what you were hoping for.
