duh, my rail voltage was too low...

I can't figure out why such a simple design isn't working.

lol, yup, pretty much why I bought a gun.

After several more hours of cleanup the Prototyping SMT board I've been working on is finally done. I attached both sides of the board below.

Here is a link if you want to order a few for yourself. If anyone is really interested I can even send a few out for free to try it out: http://dirtypcbs.com/store/designer/details/freemo/6230/smt-smd-prototyping-board-tssop-20-sop-20-sot-23-6

I havent decided yet if I want to make this open-source. I probably will.

It can act as a simple breakout board for either a single SSOP-20 or x2 SOT-23-6 chips. To use it as a normal breakout just use solder to bridge the 20 connectors on the right and left and sides of the board and it will be a normal breakout (which each pin on the chip going to one of the header pins directly).

Here is the full description.

However there is also a SMT grid on the front and back so you can solder a full circuit onto the chip and arbitrarily have any point in the circuit wired to the various pins. Which makes for very handle little modules you can solder up and reuse.

I also added two power rails for ground and VCC down the middle with vias to both sides of the board. I also added other connectors around the edge that add in vias and wires connections to the opposite side of the board. Should be very useful.

One other little hidden feature is the spacing. Most of the pads are the perfect size to fit most two terminal SMT components (x4 0603 components can solder onto a single pad). But because the pads down the middle are offset it is also very easy to solder on SOT-23 connectors that have 3 terminals. So you really can solder almost any sort of SMT components on here.

Next step will be to build a larger protoboard that can accept modules like this and similar to create more advanced circuits.

Attached are images of the top and back of the design.

Thats my sort of woman right there!

Doesnt really work that way. distributing the cost doesnt make it infinitesimal, particularly if the government inefficiencies you pointed out are accounted for (the overall cost increases).

It is just not as simple as you keep in implying. We cant have a rational or productive conversation if all you do is hold on to the dogma.

I appreciate your goal, but sadly with so many views on the political spectrum, the mentality of absolutes and dogma wont get us anywhere productive. I'm not even opposed to your idea of publicly funded public transport. I just wish to have an educated and indepth discussion about its merits. Something I am not getting here it seems...

So I got bored and did what I usually do when in bored, I needlessly improve things.

I improved my lighting system which used to run directly off a large switching power supply. It now runs off a 20v Dell power adapter which then feeds into a buck dc-dc converter which drops the voltage down to 6.4 volts and a Max current of 2.8amps with over 90% effiency. I then feed this into the light itself. The setup is working perfectly so far.

Well I know where I am going shopping when i finally snap...

lol poor billy

Because doggos.

Ok this is... interesting...

We have this tendency to not see mental health as a disease. so for most of us we never realize these sorts of connections. But it is vital we change how we look at these things for everyone's sake.

me, always.

How about being both?
