Updated Open EVSE DIY 4.23 board populated and ready for testing this weekend.

After reading the concerns about the 5V regulation, I decided to connect the digital scope to a DIY V4.21 board with a 70 ohm relay. The 5V output at the processor reads 4.98 VDC. Switching the relay on or off caused no detectable variation in the 5V regulation that exceeded the normal power...

Would you be willing to document your 78L05 mod? Thanks, Greg C. (Barbouri)

Good to hear that you are experimenting with the 4.2 board. I had four goals when building the DIY OpenEVSE boards from Chris Howell's original design. (1) Make it simple for a hobbyist with basic soldering skills. (2) Keep it compatible with existing software and hardware as possible while...

Hi Bert, Soon to be one less Leaf in Birmingham. I am in the process of moving to Mobile, AL around the end of next month. Also still loving my Leaf, it's been a great car so far. At least I managed to install one free charger for all the Bham Leafers at McWane Science Center before leaving...

Home built DIY OpenEVSE 32 amp 240 VAC system with RGB LCD display Version 4.2

Hi Gary, The cost for one from Shapeways was $25.56 plus $6.50 for shipping. I doesn't include a back. I made one from scrap white acrylic I had on hand. There doesn't appear to be a quantity discount when I selected a quantity of 10, same shipping though. Most of the side walls are near the...

Same fuseholder from Allied Electronics $14.49 http://www.alliedelec.com/search/productdetail.aspx?sku=70149367#tab=specs" onclick="window.open(this.href);return false; It is also a high quality dual fuse holder with a 600 volt rating. Greg C.

Just received my 3D printed enclosure from Shapeways that features a spot for a RGB rotary encoder with push to select and clear knob. Below is a board design that is currently out for production that features encoder and RGB connectors, and now includes circuitry for either oled or LCD...

I have been using 4 wire shielded USB 2.0 cable to connect my installed LeafCAN, which has worked well and is small enough to press into the crevice on the side of the dash. The problem with the commercial OBD2 cables that I have purchased so far has been that they are very thick, due to having...

Ground to OBD2 pin 4 Chassis Ground +12 Volt to OBD2 pin 16 Constant power or (pin 8 Switched power) EV CAN-L to OBD2 pin 12 EV CAN-L EV CAN-H to OBD2 pin 13 EV CAN-H The EV CAN is located on the OBD2 discretionary pins and is not used in many vehicles. Use the 2x3 ISP header with your...

Connected the LeafCAN display with the oled hex file from lincomatic to the Leaf today. Everything is working great! I will get it mounted a bit more securely and take it for a spin this afternoon. Eagle CAD 6.2 files are available for those wanting to print your own boards. Greg C.

LeafCAN oled board programmed with updated oled hex file from lincomatic and connected to AdaFruit 2X16 oled display. First power up with no OBDII cable or 12V supply, just 5v connected to the programming power header. So far display is operating correctly, and will test with OBDII cable on...

Thanks, Yes I did. I have done a few of the OpenEVSE RTC display boards with just the surface mount IC's in the past. This was my first full board using the Presto Liddle Griddle. I have components arriving this Friday and should be able to finish the other two boards this weekend. Greg C.
