He took two different aftermarket cases; one fits his cellphone and the other is a BlackBerry case meant for housing a credit card. After cutting a hole in the back of the cellphone case he epoxied the credit card holder in place, smoothed the seam with Bondo, and repainted. Not only does the charger fit in the credit card case, but there’s still room for a credit card. [Derek] also measured the magnetic fields around the circuitry and found they will not damage the magnetic strip on that American Express Black you’ve been keeping on you. In the video after the break he mentions the last step in finishing this case will be to locate a 90-degree USB plug as the current connector is a bit of an eyesore.
[Phil] wrote in to let us know about the DorkbotPDX group orders. The site makes group PCB orders until a cutoff date or the panel is full. You get three copies of your design with no setup fee for just $5/square inch including domestic postage. Not a bad price. We aren’t affiliated with them, but we’re always looking for board production options for hobbyists. BatchPCB is another popular one, and if you need help getting your design ready we’ve got your covered.
If you are an embedded programmer who happens to be marrying another embedded programmer take note. This wedding cake is perfect for you; decorated with character LCD screens, solderless breadboards, and development boards along with the wires that connect them all together. [Francirius], a read from Chile, says this cake was the handy work of [Paulina Verdejo].
[Todd Harrison] put together a welding cart that has all kinds of tricks built-in. The carcass is a cheap rolling cart that has been reinforced with steel plate and beefier wheels. The top tray can be loaded up with fire brick for oxygen-acetylene welding or with a grate for cutting. That grate lets the slag fall through and into the red-rimmed fire-box below. Finally, there’s a steel plate to the right of the cart that rotates and slides over the top of the unit to prepare it for MIG welding. Todd walks us through his versatile invention in the video after the break. This will nicely augment your other welding hacks.
Yes, you could argue this Nursery Room Temperature Monitor is simply an LED and an Arduino with a temperature sensor, but [Jay] really did put more thought into the process. For instance he stuck with AVR, built a wooden base and sanded globe, and even included schematics and source code. Plus, SIDS is no laughing matter and the more you know, the more it can be prevented. Back on point, one thing we would add is PWM for a more gradual change in color. What would you add?
