This blog was created so I could share the little projects that have made my life easier (or more interesting 😉 ). I hope you have fun looking around!
Hi we would love to feature your last RF Transceiver project on our website. Would you be willing to work with us in doing so?
I sent you an email.
I’m studying engineering and I would like to test the MRF49XA for a project, but I don’t want to make a some board just for that, because the cost is very expensive.
Do you sell these cards? Are you interested in selling two units?
I don’t have any way to sell them at the moment. It mostly depends on your timeframe. It’s also possible for you to make them yourself, as I have the PCB design as a public design on BatchPCB. If you are unable to make it yourself and don’t mind waiting a month for them, we can work something out.
I’m wondering if you do contract electronic design work? We have a project which might be of interest to you. I couldn’t find your contact information elsewhere, so this seemed the best way to get your attention.
Thanks for your time!
In general, yes. However, I’m in the last year of my Ph.D., so I have no time at all at the moment. Thanks for asking…
I have some questions pertaining to a wireless jeopardy system that I am attempting to construct. If you would be willing to help in this please message me.
Sure, lay ’em on me.
Do you have a contact email for future reference?
Just got Cocoa-Radio up and running on my Mac. Will start looking into the code to see if I could work with it
Hi Bill and happy New Year!
I was happy to discover cocoa radio and wanted to use it with my RTL stick, however the program starts, displays a messages that it couldn’t open the RTL stick, and promptly exits.
As it exits I didn’t know what to do or try to repair, if this was possible.
I am using a Macbook pro, OS is 10.7, Lion.
The stick is a RTLDVB-T plus FM stick with the RTL2832U chip and the RafaelMicro receiver.
Thanks for any help,
Can you provide some information from the system profiler thing? I just need to verify that the USB device is being detected by the OS. Also, what is the exact model number of the tuner chip?
William, can I get you to take a detailed, close-up, picture of the CM-5 light panel? I’m building a replica and after scouring the internet I can’t find any photos detailed enough to show what’s going on in there. I can see that there appears to be white graduations for each set of 8 LEDs and something written under each set but can’t make it out in any pictures available on the web. I thought I would take a shot and ask for your help. Driving the 500 miles to the National Cryptographic Museum in Maryland isn’t really an option right now. –Thanks, Jeff
Sure, I can do that. I’ll try to remember to do that tonight.
I updated the original CM-5 post with a close-up image of the LED panel and its silkscreen. I hope it helps.
William, the picture is perfect. Thanks for letting me take a bit of your valuable time.
There is something important to notice, depending on how much you care about authenticity. Notice that the bottom half of the LEDs look different? There is a mask of black paint on the inside of the plexi, and the bottom few banks of LEDs are completely masked out. The first bank that isn’t covered is node 45. You can see evidence of this in a few of the photos. Even though they’re masked-out, there are still LEDs under there.
I wonder if that particular CM-5 only had 45 nodes in that cabinet.
A few more questions…
In the pictures I’ve seen the LEDs look rectangular. Are they indeed rectangle LEDs or are they round?
Are the single digit nodes labeled as 01, 02, 03 or 1, 2, 3?
This CM-5 was a full load. The interesting thing is that nodes 2-45 are blacked out, nodes 46-255 aren’t. Also, I just noticed that there isn’t even a place for nodes 0 and 1.
The LEDs are round and 5mm. It’s the masking between rows that makes them look rectangular.
The single-digit nodes do not have a leading zero.
I saw your article about the helical antenna. I was given one of these, and happen to also have an Ensemble II receiver. How do use this setup to receive weather satellite data?
My article about that is here:
I’ll probably depend on whether you using windows, linux or mac. You’ll need to use GNURadio, SDR#, DSP Radio; some kind of “virtual audio cable”; and WXtoImg or WXAPT to decode the audio.
I’m planning a post about using the RTLSDR dongles for weather satellite images, too: https://twitter.com/hpux735/status/452674180970864641
Where did you find the stickers for that Cyvasse set you made?
Do you mean the bulk sticker material? I don’t remember the exact product, I think it was transparent address labels by Avery. I designed the icons on my computer and printed them onto the address labels. Then, I put them on the tiles and cut around the edges. If you use a bone-folder or something like it to press the sticker it’ll be almost clear. Also, when you paint the sticker it makes it appear almost completely transparent.
Thanks for the reply.
Yes, your process on the set is a streamlined one; I really like your lexan idea. I’m trying to make a set of my own but I don’t think I could reproduce such great sticker pieces. Would it be too much if you would send me the designs?
You’d make my year.
I looked all around, and I found most of the artwork, but some of it’s missing. I can’t find the rabble, horses, or crossbow artwork. I’m pretty sure I just google image searched for those anyway… I sent it to the email address you used with the comment. Cheers.
I absolutely appreciate it.
For your time, I’ll post this; it’s streamlined rules after many playtests. And they’re not too hard to look at either.
Please complete this capcha. I get almost 1000 spam comments a day! *
The number of projects I'm able to write about is limited by my very constrained budget. Any donation would go directly toward this fund.
