Modern vehicles are beginning to use PWM to control the output of their circuits for the same reasons Motobrain does this. This is great, but it creates an issue if you want to use the status of the OEM circuit that is using PWM to trigger a Motobrain output. A user brought this to my
Sorry gang. We are currently out of stock. Texas Instruments is backordered on a necessary chip and it is gumming up our supply chain.
1300 Motobrain PCBs were delivered last week. We are looking forward to manufacturing our new versions of Motobrain very soon.
The next generation Motobrain hardware will draw 6.4mA in standby mode. It does not scan it’s inputs for triggers in this mode. It only waits for the key signal to turn on or the Bluetooth to connect. How it works in practice is that when the key signal is off and no outputs are on
The first prototype of the new Motobrain with CANBus and automotive connector just came out of the mold. She is looking good and works well!
Building just the smart half of Motobrain, what I call the “brain board”, requires 220 surface mounted components (40 different types) with 900 individual solder joints. I will manually place all the parts on the PCB and then “reflow solder” them to the PCB. It is an arduous task to be sure. Conveniently, I believe
Here we use Motobrain’s ability to read data off the vehicle OBDii port to build a functional tachometer. This experiment is designed to show off how flexible this gizmo is.
We have a new high current PCB manufacturer and we are doing our first burn in test with their boards. We are currently driving 100A through the Motobrain to see how their boards endure the abuse. These boards use new MOSFETs (the solid state switches) which are larger than the first version of Motobrain. The
