DIY Bluetooth Speaker in Spalted Cherry

I took some time off from work the week of Thanksgiving to spend that time enjoying my family and building this cool project.

I designed and built this self-powered, Bluetooth speaker from 5/4 spalted cherry. It is powered by a Dayton Audio KAB-250 amp board (2 x 50 watts) with integrated Bluetooth chip delivered to a pair of Dayton Audio RS100-4 full range drivers. It was really fun and relatively simple to build. The most challenging part was of this project was creating the large volume control, and flush mounting the drivers. I also learned how to cut dovetailed corner keys out of mahogany to strengthen the miter joints at the corners.

I hope you enjoy the photo gallery. You can also hear how it sounds in this video demo on my facebook page (you may need to adjust the volume of the video.)


Jesus Will Always Surprise You

I try not to stray too far from the four gospels (Matthew, Mark, Luke, John) in my Bible reading and study. In any given year, I try to stick close to Jesus’ words and the story of His life in these four books. I do this partly because Jesus is the center of all that God has done for us and said to us, from Genesis to Revelation. Without Jesus…well, life-the-universe-and-everything doesn’t make much sense.

But I also stick close to the gospels because even though it’s familiar territory, each time I listen to Jesus speak through the text, He catches me off guard.

Jesus always surprises me.

Let me tell you about a recent surprise…

In 2017 I’ve been reading through the Bible chronologically. I say reading, but it’s mostly listening. About 80% of my time in the Scriptures this year has been listing to the Bible in chronological order of events using two apps: ReadingPlan and English Standard Version. I’ve found this approach really helpful when reading the Old Testament because it has helped me pick up on major themes I’ve missed before. For example, until this year, I haven’t fully appreciated the significance of this Old Testament word: steadfast love. It’s all over the Old Testament and a constant reminder of God’s faithful care for those He calls His own.

But, reading the Bible this way also means that I haven’t been in the gospels much this year. Until now.

This past week I listened to the entire book of Matthew. And there was Jesus, saying something I’ve heard, and even studied, many times in chapter 15. And yet, He caught me completely off guard. Again. Here’s the passage below. (I’ve marked Jesus responses to her in red.)

21And Jesus went away from there and withdrew to the district of Tyre and Sidon. 22And behold, a Canaanite woman from that region came out and was crying, “Have mercy on me, O Lord, Son of David; my daughter is severely oppressed by a demon.” 23But he did not answer her a word. And his disciples came and begged him, saying, “Send her away, for she is crying out after us.” 24He answered, “I was sent only to the lost sheep of the house of Israel.” 25But she came and knelt before him, saying, “Lord, help me.” 26And he answered,“It is not right to take the children’s bread and throw it to the dogs.” 27She said, “Yes, Lord, yet even the dogs eat the crumbs that fall from their masters’ table.” 28Then Jesus answered her, “O woman, great is your faith! Be it done for you as you desire.” And her daughter was healed instantly.—Matthew 15:21-28


The woman sounds pitiful, her words reveal her desperate heart, arousing our compassion. And yet, Jesus at first appears callous ignoring her, then condescending, and seeming to insult her. In fact, he almost sounds what we would call racist. Is this the picture of Jesus you learned in Sunday School?

Ultimately, of course, its a story of Jesus’ power and compassion. But, if you or I demonstrated power and compassion that way, those around us would say, “Thanks, but no thanks.” I had to stop and listen a few more times. What do I make of this Jesus—a man with the miraculous power to heal, but who alludes to her as a dog in the process?

When I considered His surprising words, I was forced to remember…

❯ I Don’t Know the Whole Story

Jesus never spoke this way to any other woman. Consider the way He spoke with another woman who was publicly accused of adultery. It was quite the opposite. He came to her defense and did not condemn her though she was guilty of the charge. So, for reasons I will never know, Jesus treated this Canaanite woman in a way that provoked her persistence and revealed her desperation. And so, she has become a parable of what Christian faith and humility looks like in action: casting one’s hopes entirely on Jesus alone.

I Am Not His Equal

If a mere man spoke like this to you, whether his intention was kind or not, you would rightly think him full of himself. When a mere man condescends and treats you as beneath him, his conceit is evident. But we know Jesus to be the only truly obedient Son of the Father. The voice of God proclaiming him so at his baptism and on the mount of transfiguration, and his own resurrection testify that Jesus is The (only) Righteous One.

So, Jesus is no mere man. The word condescension has negative connotations when applied to a man. But, the condescension of a true, divine superior is the essence of grace, mercy, and kindness. In this story, I read of a man unlike any man, a God-Man who granted an inferior audience, tested her, and amazingly, satisfied her heart’s desire. The passage teaches in surprising terms both that Jesus is good, and that I am infinitely beneath Him.

I expect Jesus will keep surprising me as I read through the rest of the gospels. It’s good to keep the gospels close and stay surprised. Otherwise, I fear I have a tendency to try to tame Him in my imagination. But as C. S. Lewis said of Aslan in The Chronicles of Narnia, He is neither tame nor safe.

I want to encourage you to meet Jesus face-to-face in the gospels, too. Pick up a Bible. Sit down. Listen. Look Him in the eye. If you want to know Jesus, that is where you will find Him. If you want to grow in faith, that is where you will hear Him command you to believe in Him. If you want to know why, that is where you’ll find the reason. If you want to grow to be a more spiritual person, He will tell you what that really means.

How Routine Effects Your Well-Being and Mental Health

Quick. What are you doing at 7:00 tomorrow morning?

If you didn’t know within a second or two, you may be missing out on one of the best ways to improve your quality of life. And if you are battling a mental health problem, you may be missing out on a powerful, free weapon in your arsenal.

It’s called: Having a routine.

❯ A Routine Is Good for Anyone

Every mom knows her kids flourish on a consistent routine, while an inconsistent schedule leads to more and more tears, outbursts, and conflict. But a consistent routine doesn’t just benefit kids. Want better sleep and feel more alert? Stick to a routine. Want to be more productive? Have a routine. Want to improve your fitness? Accomplish a goal? Feel more relaxed? Develop your spiritual life? Routine. Routine. Routine.

A routine is every adult’s friend. It helps you feel more like life is working with you, rather than against you. It produces peace of mind. It engenders calm. It reduces stress. It promotes a positive outlook on each day and a sense of well-being. A routine can build health and strength and a feeling of accomplishment. If applied wisely, it can even help strengthen relationships with the most important people in your life.

Sure, living on a consistent routine may run the risk of you being labeled: Boring. And yes, sooner or later, someone’s gonna tell you to let your hair down, to live a little, that you only live once, that you take life too seriously. But that peer-pressure is a small price to pay for the well-oiled hum of a satisfying life routine. People who live according to a routine know that low stress for the long-term is far, far better than short-term thrills or indulgences.

Of course, you can have too much of a good thing. A routine can be so rigid that it makes you intolerant of people who interrupt it. But, a good routine is flexible and makes room for people by scheduling them into it—everything from lunch with a friend to planning a Super Bowl party.

 A Routine Is a Mental Health Weapon

If having a consistent life routine is valuable when you feel yourself, just imagine how important it is for the person who feels not yourself right now.

I have observed this in my wife Dawn, who struggles with the cycles of bipolar II: hypomania, then briefly feeling herself, then depression, then repeat. In the 30+ years of our marriage, we continue to see how effective a stable routine is in managing the almost daily assault of tumultuous thoughts.

Let me give you an idea of what living a consistent routine means for Dawn:

  • It’s knowing how much water to drink every day and when.
  • It’s when she goes to bed, and when she gets up.
  • It’s knowing which foods make her feel worse (sugar, caffeine, some spices).
  • It’s avoiding music, TV, and movies that lead to more mental battles.
  • It’s what she does first thing every single morning (drink a bottle of water, a 20-minute breath to relax exercise, time reading her Bible, and writing in her journal)
  • It’s how much exercise she gets, and when, and the right kind, and the right level of intensity
  • It’s tackling a manageable set of tasks every day, not too much, not too little.
  • It’s taking time for friends and serving others, but reserving enough quiet space to be alone.
  • It’s participating in the community, but knowing her limits.
  • It’s even scheduling laundry, dishes, shopping and house cleaning so that our home always feels like a calm, peaceful place to relax.

Dawn has learned and keeps learning what works for her by reading, and talking with others, and by trial-and-error. Like blocking and tackling in football, she knows she has to keep practicing the basics of her routine to manage her challenges. I try to help in small ways too: like calling to pray with her each morning, or asking if she remembered to drink water when she feels out of sorts. I also avoid playing some of my music around her because of how it affects her.

What should your routine be like? How could it help you? How could the people who love you help you practice the basics? Only you can know. But give yourself time to learn. The benefits will be worth it.

A Routine Has These Benefits

You can think of the benefits of your routine a few different ways: as a motivator, as decision-support, as guard rails, and as a peace maker.

Think of your routine as a motivator because it can give you a reason to get out of bed in the morning. When you are depressed, it gives you something tangible and positive to do as soon as you are alert. And this can begin to stabilize your mind at the beginning of the day.

Think of your routine as decision-support because it helps you know what to do next. When your mind is foggy or fretful, any decision can seem huge and daunting, with inflated importance. But your routine will remind you of what you can do or should do next. And sometimes, getting through the next few minutes of fog with something positive to focus on is just what you need to build courage for later in the day.

Think of your routine as guard rails that keep a car from the edge of a cliff. If you feel manic or hypomanic symptoms your racing thoughts could lead to some not yourself behavior. They need to be brought smoothly to a slow, safe, sensible pace. Your routine can help you feel grounded so you can focus on one thing at a time. The next thing. And the next. And then, the next. Your routine can help you avoid behaviors or decisions that you may later regret.

And finally, a routine can help make peace within and around you. Just think. Are you more relaxed in a cluttered space or an orderly space? Does a 100 item to-do list for the day help you feel calm and confident? Do you function better when your sleep patterns vary? Are you likely to feel yourself if you skip a proper meal to binge on brownies? It’s pretty clear which habits of life promote that calm, and which destroy it. But it’s practicing your routine that will help make the life habits you need feel easy and desirable.

If you’re a take life as it comes person, I suggest you carve out some time to start thinking about the routines that will help you make a life instead. Don’t obsess about getting it right. Just start imaging how a routine could benefit you, and then take the next step that seems best to you. And then, the next. And the next.

And as always, remember Whom you are dependent on. Remember the source of your life. Jesus, our Redeemer is a ready help to the needy and contrite.
