Posted on July 1, 2011 | No CommentsI’ve been building some cabinets in the garage the last few days. I noticed that I was missing some data and dropping packets from the RF12 radios. Here is a... -
Eflite 120mAh test done!
Posted on June 28, 2011 | 2 CommentsSo a few days ago, the Jeenode stopped sending data. The beginning of this test can be found in this post. It stopped after sending 15,200 data points. That is... -
Testing the Eflite 120mAh battery with a minimal jeenode
Posted on June 17, 2011 | 4 CommentsI want to build some small wireless sensor nodes that run off small LiPo batteries and use small solar cells to charge the battery. I found some small LiPo batteries... -
Reading Lipo Voltage
Posted on June 15, 2011 | 1 CommentI’m testing a mini LiPo battery to see how long it will power a Jeenode. I bought this battery: It is listed as a 3.7V, 120mAh 1S 14C LiPo battery.... -
Reading the ARSSI pin on the Si4221/HopeRF 12B
Posted on June 14, 2011 | No CommentsThe Si4221 has a digital received signal strength indicator (RSSI). You can set a threshold in the configuration and the pin will go low when that threshold has been broken.... -
DHCP on the ENC28J60
Posted on June 7, 2011 | No CommentsExciting news! Andy has created a new library for Arduino that includes DHCP. JCW has got it working on Jeenodes it appears. Follow it here. Code is available on Github... -
