Re: 16X2 Only show blocks! Help please

Slightly off topic but have you seen i2c LCD adapters, just have to wire up SDA & SCL, can use them with 3.3v versions of the LCD1602 display meaning less components and there is a contrast pot on the i2c adapter. Those are even available as an add-on. http://www.ebay.co.uk/itm/IIC-I2C-Serial-1602-...

Re: 9$ SBC from Next Thing

I think the pertinent comment in that blog posting was "So it's not a $9 computer with $20 shipping, it's a $20 dollar computer with $9 shipping". Whatever way you stir that it comes out as a $29 computer that's still kickstarter vapourhardware. It is only $29 for those who have to pay $20 shipping...

Re: enc28j60 on pi Zero

I have a couple of these bare boards left, just need to plug in a cheap enc28j60 module, solder on pin headers / socket and should work on a Pi zero too!

Re: 5v from 12v power supply

Google "UBEC", if you use one, check the output voltage, you might need to add a diode to drop voltage. Think that these can handle upto 3A and cheap,

Re: Arduino + Raspberry Pi connection through 3.3 and relay?

Like others have said, it is possible to read an arduino output using a 2 resistor voltage divider, (see https://en.m.wikipedia.org/wiki/Voltage_divider ), you can use something like Z1:2K and Z2:3.3K to do the job, Vin would be the Arduino output and Vout the RPi gpio pin. For the pcb I made ( http...

Re: CAN Board

Hi David,

Do you have a particular model that you are after ?

I think I've got an mcp2515 board and also an obd cable both unused somewhere around ( From memory you might need to level shift when interfacing to Raspberry Pi ).

Re: Adding an ENC28J60 Ethernet module - instructions

I prototyped up a little pcb which I've tested on a model b raspberry pi, downloaded the latest NOOBS 1.9 and added the line : dtoverlay=enc28j60 to /boot/config.txt, rebooted and it worked first time, VERY easy to setup ! Anyway, got a few spare boards, if anyone is interested let me know. I can so...

Hi Carl,

How are you powering down ?
Asking as you might have problems rebooting if you're just switching the power off rather than doing a shutdown !

I2C / Nano / LCD / Real Time Clock

Hi, I'm looking for some comments on a board I've created which links a Raspberry Pi and Arduino Nano, it uses a barrel connector for power supplied (I prefer these as have spare adapters lying around but not so many micro usb), it's protected against voltage being applied the wrong way around, take...
