What is AASaver? Well, simply speaking, it’s a small voltage booster that can bump the voltages on your AA batteries to 5V or 3.3V, which you can use to power flashlight LEDs or breadboard circuits. It has some nice features, including on-board flashlight LEDs, voltage selection switch, power switch, and breadboard pin headers. I like it and I find it really useful. It is available for purchase in my online shop. Check out the full product details and a video demo on the product page:


AASaver just got posted on Hack A Day yesterday afternoon. Thanks for the publicity (Hack A Day is awesome!), orders are pouring in! The version without LEDs is already out of stock. I have placed a batch of orders and it should be back in stock in about 3 weeks. If you want to get notified when it’s back in stock, sign up for the AASaver stock notification list, or simply sign up for my blog RSS feed.
