New R48 Video Clip
Finally, a short but sweet video clip of R48 blue. I hope you enjoy…
R48 and Li-Ion Charger
R48 comes with a non-rechargeable battery (CR2450) and a black cord (lanyard) to hang around the neck. The battery lasts for about 7-8 hours in continuous run.
There are also rechargeable battery (LIR2450) and the charger available. With those, you won’t need to keep buying batteries.
The charger is very compact and plugs right into an USB port.
White LEDs look yellow when they are not lit. Other colors (red, green, and blue) look like the photo above.
Features/Notes:
- Available with 4 different color LEDs: Red, Green, Blue, and White.
- Each R48 is fully assembled, and comes with a non-rechargeable battery (CR2450, easily replaceable).
- Battery will typically last about 7-8 hours continuously.
- Also comes with black cord (lanyard) to hang R48 around your neck.
- 25 beautiful animation patterns preprogrammed.
- “Demo” mode automatically runs though all animation patterns – changes every minute. (Activated by holding the button at the startup.)
- Rechargeable battery (LIR2450) is also available as an option. This recommended option lights the LEDs brighter, as it has higher voltage.
- The charger for the above is also available.
- Dimension: 1.9 inch diameter, 0.4 inch thick (including the battery)
LIR2450 Li-Ion Battery and Charger
LIR2450 is a coin cell, Lithium-Ion rechargeable battery. Physically the same size as CR2450, LIR2450 can be used as a rechargeable replacement to CR2450 in most cases.
This little battery has little over 100 mA/Hour capacity, with nominal 3.6 V output. This battery is perfect for powering a small project.
The problem (for me) was that there were only poor quality chargers available for this very useful battery. Since I could not find a good charger for it, I made one.
This charger is based on the popular MCP73831 by Microchip to charge Lithium-Ion battery safely.
The charger is very compact and plugs right into an USB port.
Features/Notes:
- Compact design plugs into an USB port
- Charge/Done LEDs indicate the charge status
- Charge current: 45 mA typical
- Charge time: about 3 hours
- Dimension: 1.15 x 1.45 x 0.38 inches

See You at the Maker Faire Bay Area
Hello West Coast! I will be exhibiting at the Maker Faire Bay Area on May 18 & 19th.
This is the largest of Maker Faire, so I will be bringing a lot of stuff, some of which are not yet seen by anyone. (yes I’ve been working hard)
Please come see me and hundreds of great makers at this event. It will be exciting!
Laser Cut Enclosure for Color Organ Triple Deluxe II
I made a laser cut acrylic enclosure for Color Organ Triple Deluxe II.
It’s a very simple design, but very functional. Built with laser cut acrylic and screws and nuts only. No filing, glueing or bending.
You can download the design file, and laser cut 3mm acrylic. I used Ponoko, but you should be able to use any services available.
Use my design as is, or customize as you like.
You will also need four 1 inch, #2-56 machine screws and nuts, such as these.
