Triangular Solids – My First
Cheap DIY PCB Vise (less than $3)
Example Uses (Click to Enlarge)
I looked at the various PCB holders available on Amazon and found all of them wanting in some way – either too tall or too expensive (both?). This is the solution I came up with.
We Don’t Need No Stinking Bodges!
Poor Man’s Magnetic PCB Holder – Every Expense Spared!
Each of these magnetic PCB holder stanchions can be built for much less than $1 each. And the whole set up can be built for less than $15 – including the storage rack! Continue reading

Heating a Nichrome Wire with Math
I am going to be working with nichrome wire; so, I thought I would explore some of it’s properties. This is the result. Continue reading
PCB Thermal Resistance – Some Unexpected Results
When designing for an IC that uses the PCB as a heat sink, the datasheet usually only gives a single layout example – if that. But, what if you can’t implement your design exactly like the example? What are the relative effects of various compromises? It turns out that my intuition for which factors were most important was quite wrong. Continue reading
