I've purchased one of the Embeddedtronics circuit boards and have just placed a digikey order for the parts I don't have in stock.
I've also attached a spreadsheet with all the digikey numbers and prices in Canadian $ including shipping. Where I've had to buy 10 but need only one I've used the 10's cost. I've also used gold plated machine tool sockets so that the board will be servicable during my Servo learning curve.
I'll post a photo when I've assembled it and also post reports on how it works and whatever issues I have with it.
What I can say is I'm surprised at the Total cost. I'm at $151 Cdn. which doesn't include any sort of heatsink or box. I did spec in connectors that are removeable so that it will be easier to work with. That raised the price. I also went for the faster MUR120 diodes and the IRFP260N FETS which are listed as 200V and 50A. Theoretically I shouldn't toast those.
Less expensive diodes, fets and connectors could drop the price by about $30 and leave it at $120. What amazes me though is that a GECKO 340 with the step multiplier is in the same ballpark price.
So I have a general question. Why even build this if a Gecko can be had ready to go for the same or less? Especially since the 320 is currently on sale.
