Information On Building This at www.h2o2fromh2o.oregonsouth.com Update 1/212/2009: The Plans are ready come and check them out. This is the first DIY project to the H2O2FromH2O WebSite. A Simple Voltage regulator. Based on the LM317. Great for the bench to power projects while still on a bread board. Use as a bench Variable power supply. Have more then one to power your voltage hungry prototype 5V, 3.3V, 2.5V and so on. Use it on the production line to power your device under test, That’s what I made the PowerStick for. Vary cost efective when you need 10 power supplies and many diferent voltages. Photos avalible for V1.1.1 www.h2o2fromh2o.oregonsouth.com

This is great. I would to like make it pluggable to a protoboard, some pin pads would have to be? added to the artwork though.
that thing needs a heatsink, and for the negative version you can use a LM337.?
I built the Powerstick in one afternoon. Very fun and easy project to? tackle. I used an old HP printer power supply to power the device. This PS had dual voltages, +15v @ 700mA and +32v @825mA. I required only 12v so i chose to use the +15v as input. Used it to test my new H2O2 V2 PWM at my work bench. It worked flawlessly. It’s a great tool to have around. Thanks H2O2 for providing such great instruction and support. Keep up the good work.
I use this Power Supply A Phihong 24V 2.5 Model PSC60W-240 Mouser Part# 552-PSC-60W-240-R
Using A laptop power supply: From the ones I have looked at they produce 18 to 19Vdc and plenty of current. The only problem might be the plug? tip and its size. I looked at 3 and all had the right polarity, 2 Had a usable plug size, one the inside diameter was to small.
Do you think a? laptop power supply would work to power this PowerStick?
I never? thought to look at a computer fans connector. The Pad area has plenty of room to connect other plugs or just solder the wires directly.
The white header looks very similar to, if not the same as fan headers in PCs. You could use this to connect different fans at different speeds.?
Every thing is ready the plans are posted on my? website. come check it out.
Thats my left hand, You should see my right hand at work. It’s tweeking pots all day. Thanks for the Coffee straw tip, will use it? on those left handed jobs. What do you think of the PowerStick. For beginers Techs and Prototyping! At work there are 4 techs in my department and 2 variable power supplys. I plan to make one for each test fixture that needs something other than 9, 12, 15VDC.
I always hated when the screwdriver kept sliding off the screw.? Placing a small piece of tubing over the driver blade will keep it centered on the screw. I use a piece of a coffee stir straw held in place with tape. It’s the perfect size for the pot screws.
Could anyone make? use of this device?
