Solar Roller parts finally came in so now I’m done with that Project. LED Spot light design is just about done. I need to pick up a 3/4″ PVC coupler at Home Depot to finish it up.
Project #7 will be a round timer for work outs. I need to be able to time 15 2 minute rounds with a 1 minute rest in between. This should will be programmable so I can change it as I need to. Eventually I would like to work up to 15 3 minute rounds with a 30 second rest in between.
This being the 10th week of the year I’m about 3 projects behind. I do intend to make a prop for a magic trick. I have a script written and all I need is this prop.
I’ve been meaning to build one of these for some time now. I can definitely use a beefer supply than the one I’m using. This will be getting done in parallel with the Solar Roller. I just broke a lead on the voltage trigger and now I have to order another one so the roller is on hold
I’ll also be putting some time in on some LED spotlights I was meaning to build for Halloween. I’m not to crazy about the construction and I have a few ideas to make it better. This will most likely shake out to be project #6. I can use an easy win here.
On a positive note the construction of the Solar Roller is going better now that I’m using epoxy to mount the parts. The drive wheel is now a bottle cap I stuck on the motor and everything will be hanging off a paper clip.
Once I get 5 projects put away I’ll send $50.00 to Nuts Bolts & Thingamajigs.
With the Scouts Klondike Derby this week I’m going to be pressed for time. Therefore I’m picking something I have all the parts for and won’t be too taxing on my time. I won’t count making 2 trays of Sausage and Peppers as part of the 52 things. Even though that may be harder than anything else I made so far.
After a lot of unsoldering and resoldering I have the board properly rebuilt. I went from 30 AWG wire to Wire Wrap wire which is much better. When I wired the matrix to the drivers I alternated blue and white wires to better track where I was. Once that was done it was time to verify all the wiring. Out of 48 LED’s I had three bad ones. In the interest of time I went to Radio Shack and paid $1.49 for a pack of 2 3mm LED’s. I still have to slap together some Picaxe code which is 75% done. I should be finished by Sunday.
LED Cube is complete. Took a little time to troubleshoot some issues with my breakaway sockets. They don’t breakaway very clean and I lost a few pins. I didn’t need all the Arduino pins so it was easy to rearrange the socket so I had access to the pins I needed for the cube. Could use a little more power than I’m getting from just the power brick. When I have the USB port plugged in the LED’s run brighter. With the first project done I can get a few things done for project 2 which is going to be a simple mod for a case I use at work.
Started the LED cube yesterday. I know all the real Makers made them 2 years ago but I was busy then. I’m a pretty decent solderer so the assembly was pretty straight forward. This is a good project for novice solderers to practice on.
The design is pretty straight forward. 27 LED’s 3 transistors and a few resistors. I’m going to use the Arduino to control the circuit for now. As a future project I’ll probably put together a one chip Arduino and mount it directly to the board. I could also use an Ardweeny from Solarbotics. For now I don’t need the Arduino for anything else.
Hacker Happy Dance … I’ve got my Linux Enviroment up for PICAxe programming. I have a quick blikenlights test runnung using just a PICAxe and an RGB LED. My goal is to make a mini USB powered version of this very cool project by Eric Moore
