Re: LCD-ready enclosures

One thing that seems to be missing in the Electronic DIY community are LCD-ready enclosures. I agree, but the solution I would like would be a small enclosure with LCD and some basic entry/navigation buttons plus an embedded Arduino. I've made numerous projects based on the Arduino, such as a timec...

Bonus points if you can use a switch to select 3 or 5 volt output. I considered that idea but, unfortunately, the NCP1400A IC I used only comes in fixed voltage versions. There are probably other boost convertor ICs that can be switched to different voltages, but they'd probably need a different bo...

but what runs on 5V these days? ;)
Thanks. Actually, I usually run PICs and ATTinys at 5 volts for the faster speed. But, now that the PCB is proven, I have a few more boards on order and plan to assemble a few using the 3.3 volt version of the convertor IC.


Breadboard 5 Volts from a single AAA

I got tired of having to wire up a a linear regulator, filter cap and a battery box just to generate 5 volts for my breadboard projects, so my latest project courtesy of BatchPCB was born:


Firmware update?

Can we get a firmware fix for this, please. I just bought one of these for use on my Intel Mac and I'd like not to have to implement some funky solution using low speed USB hubs, and such. No offense to you guys who came up with the workaround. I'd just like to know when I can get a proper fix for t...

Would love to see a breakout board for this new 3 axis compass:

I'm very interesting in a breakout board for this IC, too. If you guys had a way for me to preorder as a show of support for this one, I'd do it. Please consider this as a product.


Upload misreads board size

 by wholder ¦  Sat Sep 20, 2008 1:40 pm ¦  Forum: BatchPCB ¦  Topic: Upload misreads board size ¦  Replies: 0 ¦  Views: 1196

After successfully uploading several designs I created in Osmond (PCB design on Mac OSX), I find that the Bot seems to misread the size of my latest board, which is intended as an Arduino sheild design. I've tried several variations to try and get it to determine the proper size, but none work prope...

PIC Xmit and Receive code for Nordic rF24L01

In the spirit of sharing I wanted to post some code for anyone that wants to play around with SF's various breakout boards for the rF24L01. I started by buying two of the "Transceiver nRF24L01 Module with RP-SMA" modules (and matching antennas), but then got spooked by having to get both the transmi...

Using nRF24AP1

I've purchased two of the "Transceiver nRF24AP1 with Trace Antenna" modules from Sparkfun and I'm in the process of writing some code to exercise them. However, the Ant protocol description docs leave a lot to be desired, IMO. They're kind of docs that I'm sure makes perfect sense to whomever that w...

FT232R Breakout GND

I was surprised to see that there does not seem to be a GND line on the two parallel rows of 8 pins config. I had to jury rig a line off the 4 end pins to get a GND signal to my proto board. Seems like an odd decision to me.
