    Easy, Cheesy 433 MHz Radio Link

    I was about to say that where I live, about a mile away from a 70cm repeater that is very high up, I had awful problems with 433 modules being swamped, even by car key fob transmitters. Another thing the operating near the amateur satellite frequencies is dubious. After all though, in the uk the...

    GPS010 with axe211?

    Hi, I was looking at the gps010 because I wanted a module with an sma connector on it. However while reading through the datasheet I saw mentioned the axe211 with a 20x2 on it. Is this a new board? as even the link shown in the datasheet throws up the 404 page not found. Thanks john

    Anyone tried dcc coding decoding with picaxe?

    Hi, Has anyone succeeded in getting a picaxe to encode and decode dcc model train data? The specs are: A 1 is represented by a 58uS for a half cycle, and a 0 at least 100uS for a half cycle. This may turn out to be too difficult, but hopefully someone might have done it. Thanks & regards john

    Hi, I notice there are quite a few threads regarding rotary encoders, except the ones I have! The part number is KY-040. It looks relatively straightforward, but I just curious if anyone else has used them. Hopefully the datasheet has attached ok. Thanks, john

    lithium batteries fake!

    Hi, I bought four 'Ultrafire 3200mah' 18650 lithium poly batteries from a company called m-zone. They advertise through amazon uk. My intention was to use either a single cell for picaxe projects, or two with an ldo regulator for 5volts. I found out that they were going flat rather quicker than...

    netserver lcd display type?

    Hi, I've recently bought two picaxe netservers. My question is which backlit lcd (or oled) can I use, and do rev-ed sell them. I tried the oled display off the axe133, and although it appears to be wired the same, I get nothing. The only backlit lcds I have all have different pin arrangements...

    axe022 pin hole diameter too small?

    Hi, recently i got two axe022 protoboards, and have had quite a few in the past. Usually the first thing i do is install 2.54mm header pins to all four ports, and the pns port. I was quite surprised when i found the pins were far too large! Seeing as these are through plated holes, therefore...
